+
+ * The merge message detection in "git cvsimport" did not catch
+   a message that began with "Merge...".
+
+ * "git status" suggests "git rm --cached" for unstaging the

+
+ * "git status" output was incorrect during a partial commit.
+
+ * "git bisect" refused to start when the HEAD was detached.
+
+ * "git bisect" allowed a wildcard character in the commit

+   them failed atomically (the answer is the former).  Reworded
+   the message to clarify this.
+
+ * "git clone" from a repository whose HEAD was misconfigured
+   did not set up the remote properly.  Now it tries to do
+   better.
+
+ * Updated git-push documentation to clarify what "matching"
+   means, in order to reduce user confusion.
+
+ * Updated git-add documentation to clarify "add -u" operates in
+   the current subdirectory you are in, just like other commands.

+==========================
+
+Fixes since v1.5.4.3
+--------------------
+
+ * Building and installing with an overtight umask such as 077 made
+   installed templates unreadable by others, while the rest of the install
+   are done in a way that is friendly to umask 022.
+
+ * "git cvsexportcommit -w $cvsdir" misbehaved when GIT_DIR is set to a
+   relative directory.
+
+ * "git http-push" had an invalid memory access that could lead it to
+   segfault.
+
+ * When "git rebase -i" gave control back to the user for a commit that is
+   marked to be edited, it just said "modify it with commit --amend",
+   without saying what to do to continue after modifying it.  Give an
+   explicit instruction to run "rebase --continue" to be more helpful.
+
+ * "git send-email" in 1.5.4.3 issued a bogus empty In-Reply-To: header.
+
+ * "git bisect" showed mysterious "won't bisect on seeked tree" error message.
+   This was leftover from Cogito days to prevent "bisect" starting from a
+   cg-seeked state.  We still keep the Cogito safety, but running "git bisect
+   start" when another bisect was in effect will clean up and start over.
+
+ * "git push" with an explicit PATH to receive-pack did not quite work if
+   receive-pack was not on usual PATH.  We earlier fixed the same issue
+   with "git fetch" and upload-pack, but somehow forgot to do so in the
+   other direction.
+
+ * git-gui's info dialog was not displayed correctly when the user tries
+   to commit nothing (i.e. without staging anything).
+
+ * "git revert" did not properly fail when attempting to run with a
+   dirty index.
+
+ * "git merge --no-commit --no-ff <other>" incorrectly made commits.
+
+ * "git merge --squash --no-ff <other>", which is a nonsense combination
+   of options, was not rejected.
+
+ * "git ls-remote" and "git remote show" against an empty repository
+   failed, instead of just giving an empty result (regression).
+
+ * "git fast-import" did not handle a renamed path whose name needs to be
+   quoted, due to a bug in unquote_c_style() function.
+
+ * "git cvsexportcommit" was confused when multiple files with the same
+   basename needed to be pushed out in the same commit.
+
+ * "git daemon" did not send early errors to syslog.
+
+ * "git log --merge" did not work well with --left-right option.
+
+ * "git svn" prompted for client cert password every time it accessed the
+   server.
+
+ * The reset command in "git fast-import" data stream was documented to
+   end with an optional LF, but it actually required one.
+
+ * "git svn dcommit/rebase" did not honor --rewrite-root option.
+
+Also included are a handful documentation updates.

+GIT v1.5.4.5 Release Notes
+==========================
+
+Fixes since v1.5.4.4
+--------------------
+
+ * "git fetch there" when the URL information came from the Cogito style
+   branches/there file did not update refs/heads/there (regression in
+   1.5.4).
+
+ * Bogus refspec configuration such as "remote.there.fetch = =" were not
+   detected as errors (regression in 1.5.4).
+
+ * You couldn't specify a custom editor whose path contains a whitespace
+   via GIT_EDITOR (and core.editor).
+
+ * The subdirectory filter to "git filter-branch" mishandled a history
+   where the subdirectory becomes empty and then later becomes non-empty.
+
+ * "git shortlog" gave an empty line if the original commit message was
+   malformed (e.g. a botched import from foreign SCM).  Now it finds the
+   first non-empty line and uses it for better information.
+
+ * When the user fails to give a revision parameter to "git svn", an error
+   from the Perl interpreter was issued because the script lacked proper
+   error checking.
+
+ * After "git rebase" stopped due to conflicts, if the user played with
+   "git reset" and friends, "git rebase --abort" failed to go back to the
+   correct commit.
+
+ * Additional work trees prepared with git-new-workdir (in contrib/) did
+   not share git-svn metadata directory .git/svn with the original.
+
+ * "git-merge-recursive" did not mark addition of the same path with
+   different filemodes correctly as a conflict.
+
+ * "gitweb" gave malformed URL when pathinfo stype paths are in use.
+
+ * "-n" stands for "--no-tags" again for "git fetch".
+
+ * "git format-patch" did not detect the need to add 8-bit MIME header
+   when the user used format.header configuration.
+
+ * "rev~" revision specifier used to mean "rev", which was inconsistent
+   with how "rev^" worked.  Now "rev~" is the same as "rev~1" (hence it
+   also is the same as "rev^1"), and "rev~0" is the same as "rev^0"
+   (i.e. it has to be a commit).
+
+ * "git quiltimport" did not grok empty lines, lines in "file -pNNN"
+   format to specify the prefix levels and lines with trailing comments.
+
+ * "git rebase -m" triggered pre-commit verification, which made
+   "rebase --continue" impossible.
+

+GIT v1.5.4.6 Release Notes
+==========================
+
+I personally do not think there is any reason anybody should want to
+run v1.5.4.X series these days, because 'master' version is always
+more stable than any tagged released version of git.
+
+This is primarily to futureproof "git-shell" to accept requests
+without a dash between "git" and subcommand name (e.g. "git
+upload-pack") which the newer client will start to make sometime in
+the future.
+
+Fixes since v1.5.4.5
+--------------------
+
+ * Command line option "-n" to "git-repack" was not correctly parsed.
+
+ * Error messages from "git-apply" when the patchfile cannot be opened
+   have been improved.
+
+ * Error messages from "git-bisect" when given nonsense revisions have
+   been improved.
+
+ * reflog syntax that uses time e.g. "HEAD@{10 seconds ago}:path" did not
+   stop parsing at the closing "}".
+
+ * "git rev-parse --symbolic-full-name ^master^2" printed solitary "^",
+   but it should print nothing.
+
+ * "git apply" did not enforce "match at the beginning" correctly.
+
+ * a path specification "a/b" in .gitattributes file should not match
+   "sub/a/b", but it did.
+
+ * "git log --date-order --topo-order" did not override the earlier
+   date-order with topo-order as expected.
+
+ * "git fast-export" did not export octopus merges correctly.
+
+ * "git archive --prefix=$path/" mishandled gitattributes.
+
+As usual, it also comes with many documentation fixes and clarifications.

+GIT v1.5.5 Release Notes
+========================
+
+Updates since v1.5.4
+--------------------
+
+(subsystems)
+
+ * Comes with git-gui 0.10.1
+
+(portability)
+
+ * We shouldn't ask for BSD group ownership semantics by setting g+s bit
+   on directories on older BSD systems that refuses chmod() by non root
+   users.  BSD semantics is the default there anyway.
+
+ * Bunch of portability improvement patches coming from an effort to port
+   to Solaris has been applied.
+
+(performance)
+
+ * On platforms with suboptimal qsort(3) implementation, there
+   is an option to use more reasonable substitute we ship with
+   our software.
+
+ * New configuration variable "pack.packsizelimit" can be used
+   in place of command line option --max-pack-size.
+
+ * "git fetch" over the native git protocol used to make a
+   connection to find out the set of current remote refs and
+   another to actually download the pack data.  We now use only
+   one connection for these tasks.
+
+ * "git commit" does not run lstat(2) more than necessary
+   anymore.
+
+(usability, bells and whistles)
+
+ * Bash completion script (in contrib) are aware of more commands and
+   options.
+
+ * You can be warned when core.autocrlf conversion is applied in
+   such a way that results in an irreversible conversion.
+
+ * A catch-all "color.ui" configuration variable can be used to
+   enable coloring of all color-capable commands, instead of
+   individual ones such as "color.status" and "color.branch".
+
+ * The commands refused to take absolute pathnames where they
+   require pathnames relative to the work tree or the current
+   subdirectory.  They now can take absolute pathnames in such a
+   case as long as the pathnames do not refer outside of the
+   work tree.  E.g. "git add $(pwd)/foo" now works.
+
+ * Error messages used to be sent to stderr, only to get hidden,
+   when $PAGER was in use.  They now are sent to stdout along
+   with the command output to be shown in the $PAGER.
+
+ * A pattern "foo/" in .gitignore file now matches a directory
+   "foo".  Pattern "foo" also matches as before.
+
+ * bash completion's prompt helper function can talk about
+   operation in-progress (e.g. merge, rebase, etc.).
+
+ * Configuration variables "url.<usethis>.insteadof = <otherurl>" can be
+   used to tell "git-fetch" and "git-push" to use different URL than what
+   is given from the command line.
+
+ * "git add -i" behaves better even before you make an initial commit.
+
+ * "git am" refused to run from a subdirectory without a good reason.
+
+ * After "git apply --whitespace=fix" fixes whitespace errors in a patch,
+   a line before the fix can appear as a context or preimage line in a
+   later patch, causing the patch not to apply.  The command now knows to
+   see through whitespace fixes done to context lines to successfully
+   apply such a patch series.
+
+ * "git branch" (and "git checkout -b") to branch from a local branch can
+   optionally set "branch.<name>.merge" to mark the new branch to build on
+   the other local branch, when "branch.autosetupmerge" is set to
+   "always", or when passing the command line option "--track" (this option
+   was ignored when branching from local branches).  By default, this does
+   not happen when branching from a local branch.
+
+ * "git checkout" to switch to a branch that has "branch.<name>.merge" set
+   (i.e. marked to build on another branch) reports how much the branch
+   and the other branch diverged.
+
+ * When "git checkout" has to update a lot of paths, it used to be silent
+   for 4 seconds before it showed any progress report.  It is now a bit
+   more impatient and starts showing progress report early.
+
+ * "git commit" learned a new hook "prepare-commit-msg" that can
+   inspect what is going to be committed and prepare the commit
+   log message template to be edited.
+
+ * "git cvsimport" can now take more than one -M options.
+
+ * "git describe" learned to limit the tags to be used for
+   naming with --match option.
+
+ * "git describe --contains" now barfs when the named commit
+   cannot be described.
+
+ * "git describe --exact-match" describes only commits that are tagged.
+
+ * "git describe --long" describes a tagged commit as $tag-0-$sha1,
+   instead of just showing the exact tagname.
+
+ * "git describe" warns when using a tag whose name and path contradict
+   with each other.
+
+ * "git diff" learned "--relative" option to limit and output paths
+   relative to the current directory when working in a subdirectory.
+
+ * "git diff" learned "--dirstat" option to show birds-eye-summary of
+   changes more concisely than "--diffstat".
+
+ * "git format-patch" learned --cover-letter option to generate a cover
+   letter template.
+
+ * "git gc" learned --quiet option.
+
+ * "git gc" now automatically prunes unreachable objects that are two
+   weeks old or older.
+
+ * "git gc --auto" can be disabled more easily by just setting gc.auto
+   to zero.  It also tolerates more packfiles by default.
+
+ * "git grep" now knows "--name-only" is a synonym for the "-l" option.
+
+ * "git help <alias>" now reports "'git <alias>' is alias to <what>",
+   instead of saying "No manual entry for git-<alias>".
+
+ * "git help" can use different backends to show manual pages and this can
+   be configured using "man.viewer" configuration.
+
+ * "gitk" does not restore window position from $HOME/.gitk anymore (it
+   still restores the size).
+
+ * "git log --grep=<what>" learned "--fixed-strings" option to look for
+   <what> without treating it as a regular expression.
+
+ * "git gui" learned an auto-spell checking.
+
+ * "git push <somewhere> HEAD" and "git push <somewhere> +HEAD" works as
+   expected; they push the current branch (and only the current branch).
+   In addition, HEAD can be written as the value of "remote.<there>.push"
+   configuration variable.
+
+ * When the configuration variable "pack.threads" is set to 0, "git
+   repack" auto detects the number of CPUs and uses that many threads.
+
+ * "git send-email" learned to prompt for passwords
+   interactively.
+
+ * "git send-email" learned an easier way to suppress CC
+   recipients.
+
+ * "git stash" learned "pop" command, that applies the latest stash and
+   removes it from the stash, and "drop" command to discard the named
+   stash entry.
+
+ * "git submodule" learned a new subcommand "summary" to show the
+   symmetric difference between the HEAD version and the work tree version
+   of the submodule commits.
+
+ * Various "git cvsimport", "git cvsexportcommit", "git cvsserver",
+   "git svn" and "git p4" improvements.
+
+(internal)
+
+ * Duplicated code between git-help and git-instaweb that
+   launches user's preferred browser has been refactored.
+
+ * It is now easier to write test scripts that records known
+   breakages.
+
+ * "git checkout" is rewritten in C.
+
+ * "git remote" is rewritten in C.
+
+ * Two conflict hunks that are separated by a very short span of common
+   lines are now coalesced into one larger hunk, to make the result easier
+   to read.
+
+ * Run-command API's use of file descriptors is documented clearer and
+   is more consistent now.
+
+ * diff output can be sent to FILE * that is different from stdout.  This
+   will help reimplementing more things in C.
+
+Fixes since v1.5.4
+------------------
+
+All of the fixes in v1.5.4 maintenance series are included in
+this release, unless otherwise noted.
+
+ * "git-http-push" did not allow deletion of remote ref with the usual
+   "push <remote> :<branch>" syntax.
+
+ * "git-rebase --abort" did not go back to the right location if
+   "git-reset" was run during the "git-rebase" session.
+

+-----------
+

+   subcommand name (e.g. "git upload-pack") which the newer client will
+   start to make sometime in the future.
+
+Fixes since v1.5.6.1
+--------------------
+
+* "git clone" from a remote that is named with url.insteadOf setting in
+  $HOME/.gitconfig did not work well.
+
+* "git describe --long --tags" segfaulted when the described revision was
+  tagged with a lightweight tag.
+
+* "git diff --check" did not report the result via its exit status
+  reliably.
+
+* When remote side used to have branch 'foo' and git-fetch finds that now
+  it has branch 'foo/bar', it refuses to lose the existing remote tracking
+  branch and its reflog.  The error message has been improved to suggest
+  pruning the remote if the user wants to proceed and get the latest set
+  of branches from the remote, including such 'foo/bar'.
+
+* "git reset file" should mean the same thing as "git reset HEAD file",
+  but we required disambiguating -- even when "file" is not ambiguous.
+
+* "git show" segfaulted when an annotated tag that points at another
+  annotated tag was given to it.
+
+* Optimization for a large import via "git-svn" introduced in v1.5.6 had a
+  serious memory and temporary file leak, which made it unusable for
+  moderately large import.

+
+* Setting core.sharerepository to traditional "true" value was supposed to make

+  that the path is now unchanged.
+
+* The section that describes attributes related to git-archive were placed
+  in a wrong place in the gitattributes(5) manual page.
+
+* "git am" was not helpful to the users when it detected that the committer
+  information is not set up properly yet.
+
+* "git clone" had a leftover debugging fprintf().
+
+* "git clone -q" was not quiet enough as it used to and gave object count
+  and progress reports.
+
+* "git clone" marked downloaded packfile with .keep; this could be a
+  good thing if the remote side is well packed but otherwise not,
+  especially for a project that is not really big.
+
+* "git daemon" used to call syslog() from a signal handler, which
+  could raise signals of its own but generally is not reentrant.  This
+  was fixed by restructuring the code to report syslog() after the handler
+  returns.
+
+* When "git push" tries to remove a remote ref, and corresponding
+  tracking ref is missing, we used to report error (i.e. failure to
+  remove something that does not exist).
+
+* "git mailinfo" (hence "git am") did not handle commit log messages in a
+  MIME multipart mail correctly.

+  with small PATH_MAX value in a repository that has contents with
+  long pathnames.
+
+* There wasn't a way to make --pretty=format:%<> specifiers to honor

+
+* "git-cvsserver" did not clean up its temporary working area after annotate
+  request.
+
+* "git-daemon" called syslog() from its signal handler, which was a
+  no-no.
+
+* "git-fetch" into an empty repository used to remind that the fetch will
+   be huge by saying "no common commits", but this was an unnecessary
+   noise; it is already known by the user anyway.
+
+* "git-http-fetch" would have segfaulted when pack idx file retrieved
+  from the other side was corrupt.
+
+* "git-index-pack" used too much memory when dealing with a deep delta chain.
+
+* "git-mailinfo" (hence "git-am") did not correctly handle in-body [PATCH]
+  line to override the commit title taken from the mail Subject header.
+
+* "git-rebase -i -p" lost parents that are not involved in the history
+  being rewritten.
+
+* "git-rm" lost track of where the index file was when GIT_DIR was
+  specified as a relative path.
+
+* "git-rev-list --quiet" was not quiet as advertised.

+GIT v1.5.6 Release Notes
+========================
+
+Updates since v1.5.5
+--------------------
+
+(subsystems)
+
+* Comes with updated gitk and git-gui.
+
+(portability)
+
+* git will build on AIX better than before now.
+
+* core.ignorecase configuration variable can be used to work better on
+  filesystems that are not case sensitive.
+
+* "git init" now autodetects the case sensitivity of the filesystem and
+  sets core.ignorecase accordingly.
+
+* cpio is no longer used; neither "curl" binary (libcurl is still used).
+
+(documentation)
+
+* Many freestanding documentation pages have been converted and made
+  available to "git help" (aka "man git<something>") as section 7 of
+  the manual pages. This means bookmarks to some HTML documentation
+  files may need to be updated (eg "tutorial.html" became
+  "gittutorial.html").
+
+(performance)
+
+* "git clone" was rewritten in C.  This will hopefully help cloning a
+  repository with insane number of refs.
+
+* "git rebase --onto $there $from $branch" used to switch to the tip of
+  $branch only to immediately reset back to $from, smudging work tree
+  files unnecessarily.  This has been optimized.
+
+* Object creation codepath in "git-svn" has been optimized by enhancing
+  plumbing commands git-cat-file and git-hash-object.
+
+(usability, bells and whistles)
+
+* "git add -p" (and the "patch" subcommand of "git add -i") can choose to
+  apply (or not apply) mode changes independently from contents changes.
+
+* "git bisect help" gives longer and more helpful usage information.
+
+* "git bisect" does not use a special branch "bisect" anymore; instead, it
+  does its work on a detached HEAD.
+
+* "git branch" (and "git checkout -b") can be told to set up
+  branch.<name>.rebase automatically, so that later you can say "git pull"
+  and magically cause "git pull --rebase" to happen.
+
+* "git branch --merged" and "git branch --no-merged" can be used to list
+  branches that have already been merged (or not yet merged) to the
+  current branch.
+
+* "git cherry-pick" and "git revert" can add a sign-off.
+
+* "git commit" mentions the author identity when you are committing
+  somebody else's changes.
+
+* "git diff/log --dirstat" output is consistent between binary and textual
+  changes.
+
+* "git filter-branch" rewrites signed tags by demoting them to annotated.
+
+* "git format-patch --no-binary" can produce a patch that lack binary
+  changes (i.e. cannot be used to propagate the whole changes) meant only
+  for reviewing.
+
+* "git init --bare" is a synonym for "git --bare init" now.
+
+* "git gc --auto" honors a new pre-auto-gc hook to temporarily disable it.
+
+* "git log --pretty=tformat:<custom format>" gives a LF after each entry,
+  instead of giving a LF between each pair of entries which is how
+  "git log --pretty=format:<custom format>" works.
+
+* "git log" and friends learned the "--graph" option to show the ancestry
+  graph at the left margin of the output.
+
+* "git log" and friends can be told to use date format that is different
+  from the default via 'log.date' configuration variable.
+
+* "git send-email" now can send out messages outside a git repository.
+
+* "git send-email --compose" was made aware of rfc2047 quoting.
+
+* "git status" can optionally include output from "git submodule
+  summary".
+
+* "git svn" learned --add-author-from option to propagate the authorship
+  by munging the commit log message.
+
+* new object creation and looking up in "git svn" has been optimized.
+
+* "gitweb" can read from a system-wide configuration file.
+
+(internal)
+
+* "git unpack-objects" and "git receive-pack" is now more strict about
+  detecting breakage in the objects they receive over the wire.

+GIT v1.6.0 Release Notes
+========================
+
+User visible changes
+--------------------
+
+With the default Makefile settings, most of the programs are now
+installed outside your $PATH, except for "git", "gitk" and
+some server side programs that need to be accessible for technical
+reasons.  Invoking a git subcommand as "git-xyzzy" from the command
+line has been deprecated since early 2006 (and officially announced in
+1.5.4 release notes); use of them from your scripts after adding
+output from "git --exec-path" to the $PATH is still supported in this
+release, but users are again strongly encouraged to adjust their
+scripts to use "git xyzzy" form, as we will stop installing
+"git-xyzzy" hardlinks for built-in commands in later releases.
+
+An earlier change to page "git status" output was overwhelmingly unpopular
+and has been reverted.
+
+Source changes needed for porting to MinGW environment are now all in the
+main git.git codebase.
+
+By default, packfiles created with this version uses delta-base-offset
+encoding introduced in v1.4.4.  Pack idx files are using version 2 that
+allows larger packs and added robustness thanks to its CRC checking,
+introduced in v1.5.2 and v1.4.4.5.  If you want to keep your repositories
+backwards compatible past these versions, set repack.useDeltaBaseOffset
+to false or pack.indexVersion to 1, respectively.
+
+We used to prevent sample hook scripts shipped in templates/ from
+triggering by default by relying on the fact that we install them as
+unexecutable, but on some filesystems, this approach does not work.
+They are now shipped with ".sample" suffix.  If you want to activate
+any of these samples as-is, rename them to drop the ".sample" suffix,
+instead of running "chmod +x" on them.  For example, you can rename
+hooks/post-update.sample to hooks/post-update to enable the sample
+hook that runs update-server-info, in order to make repositories
+friendly to dumb protocols (i.e. HTTP).
+
+GIT_CONFIG, which was only documented as affecting "git config", but
+actually affected all git commands, now only affects "git config".
+GIT_LOCAL_CONFIG, also only documented as affecting "git config" and
+not different from GIT_CONFIG in a useful way, is removed.
+
+The ".dotest" temporary area "git am" and "git rebase" use is now moved
+inside the $GIT_DIR, to avoid mistakes of adding it to the project by
+accident.
+
+An ancient merge strategy "stupid" has been removed.
+
+
+Updates since v1.5.6
+--------------------
+
+(subsystems)
+
+* git-p4 in contrib learned "allowSubmit" configuration to control on
+  which branch to allow "submit" subcommand.
+
+* git-gui learned to stage changes per-line.
+
+(portability)
+
+* Changes for MinGW port have been merged, thanks to Johannes Sixt and
+  gangs.
+
+* Sample hook scripts shipped in templates/ are now suffixed with
+  *.sample.
+
+* perl's in-place edit (-i) does not work well without backup files on Windows;
+  some tests are rewritten to cope with this.
+
+(documentation)
+
+* Updated howto/update-hook-example
+
+* Got rid of usage of "git-foo" from the tutorial and made typography
+  more consistent.
+
+* Disambiguating "--" between revs and paths is finally documented.
+
+(performance, robustness, sanity etc.)
+
+* index-pack used too much memory when dealing with a deep delta chain.
+  This has been optimized.
+
+* reduced excessive inlining to shrink size of the "git" binary.
+
+* verify-pack checks the object CRC when using version 2 idx files.
+
+* When an object is corrupt in a pack, the object became unusable even
+  when the same object is available in a loose form,  We now try harder to
+  fall back to these redundant objects when able.  In particular, "git
+  repack -a -f" can be used to fix such a corruption as long as necessary
+  objects are available.
+
+* Performance of "git-blame -C -C" operation is vastly improved.
+
+* git-clone does not create refs in loose form anymore (it behaves as
+  if you immediately ran git-pack-refs after cloning).  This will help
+  repositories with insanely large number of refs.
+
+* core.fsyncobjectfiles configuration can be used to ensure that the loose
+  objects created will be fsync'ed (this is only useful on filesystems
+  that does not order data writes properly).
+
+* "git commit-tree" plumbing can make Octopus with more than 16 parents.
+  "git commit" has been capable of this for quite some time.
+
+(usability, bells and whistles)
+
+* even more documentation pages are now accessible via "man" and "git help".
+
+* A new environment variable GIT_CEILING_DIRECTORIES can be used to stop
+  the discovery process of the toplevel of working tree; this may be useful
+  when you are working in a slow network disk and are outside any working tree,
+  as bash-completion and "git help" may still need to run in these places.
+
+* By default, stash entries never expire.  Set reflogexpire in [gc
+  "refs/stash"] to a reasonable value to get traditional auto-expiration
+  behaviour back
+
+* Longstanding latency issue with bash completion script has been
+  addressed.  This will need to be backmerged to 'maint' later.
+
+* pager.<cmd> configuration variable can be used to enable/disable the
+  default paging behaviour per command.
+
+* "git-add -i" has a new action 'e/dit' to allow you edit the patch hunk
+  manually.
+
+* git-am records the original tip of the branch in ORIG_HEAD before it
+  starts applying patches.
+
+* git-apply can handle a patch that touches the same path more than once
+  much better than before.
+
+* git-apply can be told not to trust the line counts recorded in the input
+  patch but recount, with the new --recount option.
+
+* git-apply can be told to apply a patch to a path deeper than what the
+  patch records with --directory option.
+
+* git-archive can be told to omit certain paths from its output using
+  export-ignore attributes.
+
+* git-archive uses the zlib default compression level when creating
+  zip archive.
+
+* git-archive's command line options --exec and --remote can take their
+  parameters as separate command line arguments, similar to other commands.
+  IOW, both "--exec=path" and "--exec path" are now supported.
+
+* With -v option, git-branch describes the remote tracking statistics
+  similar to the way git-checkout reports by how many commits your branch
+  is ahead/behind.
+
+* git-branch's --contains option used to always require a commit parameter
+  to limit the branches with; it now defaults to list branches that
+  contains HEAD if this parameter is omitted.
+
+* git-branch's --merged and --no-merged option used to always limit the
+  branches relative to the HEAD, but they can now take an optional commit
+  argument that is used in place of HEAD.
+
+* git-bundle can read the revision arguments from the standard input.
+
+* git-cherry-pick can replay a root commit now.
+
+* git-clone can clone from a remote whose URL would be rewritten by
+  configuration stored in $HOME/.gitconfig now.
+
+* "git-clone --mirror" is a handy way to set up a bare mirror repository.
+
+* git-cvsserver learned to respond to "cvs co -c".
+
+* git-diff --check now checks leftover merge conflict markers.
+
+* "git-diff -p" learned to grab a better hunk header lines in
+  BibTex, Pascal/Delphi, and Ruby files and also pays attention to
+  chapter and part boundary in TeX documents.
+
+* When remote side used to have branch 'foo' and git-fetch finds that now
+  it has branch 'foo/bar', it refuses to lose the existing remote tracking
+  branch and its reflog.  The error message has been improved to suggest
+  pruning the remote if the user wants to proceed and get the latest set
+  of branches from the remote, including such 'foo/bar'.
+
+* fast-export learned to export and import marks file; this can be used to
+  interface with fast-import incrementally.
+
+* fast-import and fast-export learned to export and import gitlinks.
+
+* "gitk" left background process behind after being asked to dig very deep
+  history and the user killed the UI; the process is killed when the UI goes
+  away now.
+
+* git-rebase records the original tip of branch in ORIG_HEAD before it is
+  rewound.
+
+* "git rerere" can be told to update the index with auto-reused resolution
+  with rerere.autoupdate configuration variable.
+
+* git-rev-parse learned $commit^! and $commit^@ notations used in "log"
+  family.  These notations are available in gitk as well, because the gitk
+  command internally uses rev-parse to interpret its arguments.
+
+* git-rev-list learned --children option to show child commits it
+  encountered during the traversal, instead of showing parent commits.
+
+* git-send-mail can talk not just over SSL but over TLS now.
+
+* git-shortlog honors custom output format specified with "--pretty=format:".
+
+* "git-stash save" learned --keep-index option.  This lets you stash away the
+  local changes and bring the changes staged in the index to your working
+  tree for examination and testing.
+
+* git-stash also learned branch subcommand to create a new branch out of
+  stashed changes.
+
+* git-status gives the remote tracking statistics similar to the way
+  git-checkout reports by how many commits your branch is ahead/behind.
+
+* "git-svn dcommit" is now aware of auto-props setting the subversion user
+  has.
+
+* You can tell "git status -u" to even more aggressively omit checking
+  untracked files with --untracked-files=no.
+
+* Original SHA-1 value for "update-ref -d" is optional now.
+
+* Error codes from gitweb are made more descriptive where possible, rather
+  than "403 forbidden" as we used to issue everywhere.
+
+(internal)
+
+* git-merge has been reimplemented in C.
+
+
+Fixes since v1.5.6
+------------------
+
+All of the fixes in v1.5.6 maintenance series are included in
+this release, unless otherwise noted.
+
+ * git-clone ignored its -u option; the fix needs to be backported to
+   'maint';
+
+ * git-mv used to lose the distinction between changes that are staged
+   and that are only in the working tree, by staging both in the index
+   after moving such a path.
+
+ * "git-rebase -i -p" rewrote the parents to wrong ones when amending
+   (either edit or squash) was involved, and did not work correctly
+   when fast forwarding.

+     the change.
+
+     The people who may need to know are the ones whose code you
+     are butchering.  These people happen to be the ones who are
+     most likely to be knowledgeable enough to help you, but
+     they have no obligation to help you (i.e. you ask for help,

+ (2) You get comments and suggestions for improvements.  You may
+     even get them in a "on top of your change" patch form.
+
+ (3) Polish, refine, and re-send to the list and the people who
+     spend their time to improve your patch.  Go back to step (2).
+
+ (4) The list forms consensus that the last round of your patch is
+     good.  Send it to the list and cc the maintainer.
+
+ (5) A topic branch is created with the patch and is merged to 'next',
+     and cooked further and eventually graduates to 'master'.
+
+In any time between the (2)-(3) cycle, the maintainer may pick it up
+from the list and queue it to 'pu', in order to make it easier for
+people play with it without having to pick up and apply the patch to

+CRLF conversion bears a slight chance of corrupting data.
+autocrlf=true will convert CRLF to LF during commit and LF to
+CRLF during checkout.  A file that contains a mixture of LF and
+CRLF before the commit cannot be recreated by git.  For text
+files this is the right thing to do: it corrects line endings
+such that we have only LF line endings in the repository.
+But for binary files that are accidentally classified as text the
+conversion can corrupt data.
++
+If you recognize such corruption early you can easily fix it by
+setting the conversion type explicitly in .gitattributes.  Right
+after committing you still have the original file in your work
+tree and this file is not yet corrupted.  You can explicitly tell
+git that this file is binary and git will handle the file
+appropriately.
++
+Unfortunately, the desired effect of cleaning up text files with
+mixed line endings and the undesired effect of corrupting binary
+files cannot be distinguished.  In both cases CRLFs are removed
+in an irreversible way.  For text files this is the right thing
+to do because CRLFs are line endings, while for binary files
+converting CRLFs corrupts data.
++
+Note, this safety check does not mean that a checkout will generate a
+file identical to the original file for a different setting of
+`core.autocrlf`, but only for the current one.  For example, a text
+file with `LF` would be accepted with `core.autocrlf=input` and could
+later be checked out with `core.autocrlf=true`, in which case the
+resulting file would contain `CRLF`, although the original file
+contained `LF`.  However, in both work trees the line endings would be
+consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
+file with mixed line endings would be reported by the `core.safecrlf`

-A git core tutorial for developers
-==================================
-
-Introduction
-------------
-
-This tutorial explains how to use the "core" git programs to set up and
-work with a git repository.
-
-If you just need to use git as a revision control system you may prefer
-to start with link:tutorial.html[a tutorial introduction to git] or
-link:user-manual.html[the git user manual].
-
-However, an understanding of these low-level tools can be helpful if
-you want to understand git's internals.
-
-The core git is often called "plumbing", with the prettier user
-interfaces on top of it called "porcelain". You may not want to use the
-plumbing directly very often, but it can be good to know what the
-plumbing does for when the porcelain isn't flushing.
-
-[NOTE]
-Deeper technical details are often marked as Notes, which you can
-skip on your first reading.
-
-
-Creating a git repository
--------------------------
-
-Creating a new git repository couldn't be easier: all git repositories start
-out empty, and the only thing you need to do is find yourself a
-subdirectory that you want to use as a working tree - either an empty
-one for a totally new project, or an existing working tree that you want
-to import into git.
-
-For our first example, we're going to start a totally new repository from
-scratch, with no pre-existing files, and we'll call it `git-tutorial`.
-To start up, create a subdirectory for it, change into that
-subdirectory, and initialize the git infrastructure with `git-init`:
-
-------------------------------------------------
-$ mkdir git-tutorial
-$ cd git-tutorial
-$ git-init
-------------------------------------------------
-
-to which git will reply
-
-----------------
-Initialized empty Git repository in .git/
-----------------
-
-which is just git's way of saying that you haven't been doing anything
-strange, and that it will have created a local `.git` directory setup for
-your new project. You will now have a `.git` directory, and you can
-inspect that with `ls`. For your new empty project, it should show you
-three entries, among other things:
-
- - a file called `HEAD`, that has `ref: refs/heads/master` in it.
-   This is similar to a symbolic link and points at
-   `refs/heads/master` relative to the `HEAD` file.
-+
-Don't worry about the fact that the file that the `HEAD` link points to
-doesn't even exist yet -- you haven't created the commit that will
-start your `HEAD` development branch yet.
-
- - a subdirectory called `objects`, which will contain all the
-   objects of your project. You should never have any real reason to
-   look at the objects directly, but you might want to know that these
-   objects are what contains all the real 'data' in your repository.
-
- - a subdirectory called `refs`, which contains references to objects.
-
-In particular, the `refs` subdirectory will contain two other
-subdirectories, named `heads` and `tags` respectively. They do
-exactly what their names imply: they contain references to any number
-of different 'heads' of development (aka 'branches'), and to any
-'tags' that you have created to name specific versions in your
-repository.
-
-One note: the special `master` head is the default branch, which is
-why the `.git/HEAD` file was created points to it even if it
-doesn't yet exist. Basically, the `HEAD` link is supposed to always
-point to the branch you are working on right now, and you always
-start out expecting to work on the `master` branch.
-
-However, this is only a convention, and you can name your branches
-anything you want, and don't have to ever even 'have' a `master`
-branch. A number of the git tools will assume that `.git/HEAD` is
-valid, though.
-
-[NOTE]
-An 'object' is identified by its 160-bit SHA1 hash, aka 'object name',
-and a reference to an object is always the 40-byte hex
-representation of that SHA1 name. The files in the `refs`
-subdirectory are expected to contain these hex references
-(usually with a final `\'\n\'` at the end), and you should thus
-expect to see a number of 41-byte files containing these
-references in these `refs` subdirectories when you actually start
-populating your tree.
-
-[NOTE]
-An advanced user may want to take a look at the
-link:repository-layout.html[repository layout] document
-after finishing this tutorial.
-
-You have now created your first git repository. Of course, since it's
-empty, that's not very useful, so let's start populating it with data.
-
-
-Populating a git repository
----------------------------
-
-We'll keep this simple and stupid, so we'll start off with populating a
-few trivial files just to get a feel for it.
-
-Start off with just creating any random files that you want to maintain
-in your git repository. We'll start off with a few bad examples, just to
-get a feel for how this works:
-
-------------------------------------------------
-$ echo "Hello World" >hello
-$ echo "Silly example" >example
-------------------------------------------------
-
-you have now created two files in your working tree (aka 'working directory'),
-but to actually check in your hard work, you will have to go through two steps:
-
- - fill in the 'index' file (aka 'cache') with the information about your
-   working tree state.
-
- - commit that index file as an object.
-
-The first step is trivial: when you want to tell git about any changes
-to your working tree, you use the `git-update-index` program. That
-program normally just takes a list of filenames you want to update, but
-to avoid trivial mistakes, it refuses to add new entries to the index
-(or remove existing ones) unless you explicitly tell it that you're
-adding a new entry with the `\--add` flag (or removing an entry with the
-`\--remove`) flag.
-
-So to populate the index with the two files you just created, you can do
-
-------------------------------------------------
-$ git-update-index --add hello example
-------------------------------------------------
-
-and you have now told git to track those two files.
-
-In fact, as you did that, if you now look into your object directory,
-you'll notice that git will have added two new objects to the object
-database. If you did exactly the steps above, you should now be able to do
-
-
-----------------
-$ ls .git/objects/??/*
-----------------
-
-and see two files:
-
-----------------
-.git/objects/55/7db03de997c86a4a028e1ebd3a1ceb225be238
-.git/objects/f2/4c74a2e500f5ee1332c86b94199f52b1d1d962
-----------------
-
-which correspond with the objects with names of `557db...` and
-`f24c7...` respectively.
-
-If you want to, you can use `git-cat-file` to look at those objects, but
-you'll have to use the object name, not the filename of the object:
-
-----------------
-$ git-cat-file -t 557db03de997c86a4a028e1ebd3a1ceb225be238
-----------------
-
-where the `-t` tells `git-cat-file` to tell you what the "type" of the
-object is. git will tell you that you have a "blob" object (i.e., just a
-regular file), and you can see the contents with
-
-----------------
-$ git-cat-file "blob" 557db03
-----------------
-
-which will print out "Hello World". The object `557db03` is nothing
-more than the contents of your file `hello`.
-
-[NOTE]
-Don't confuse that object with the file `hello` itself. The
-object is literally just those specific *contents* of the file, and
-however much you later change the contents in file `hello`, the object
-we just looked at will never change. Objects are immutable.
-
-[NOTE]
-The second example demonstrates that you can
-abbreviate the object name to only the first several
-hexadecimal digits in most places.
-
-Anyway, as we mentioned previously, you normally never actually take a
-look at the objects themselves, and typing long 40-character hex
-names is not something you'd normally want to do. The above digression
-was just to show that `git-update-index` did something magical, and
-actually saved away the contents of your files into the git object
-database.
-
-Updating the index did something else too: it created a `.git/index`
-file. This is the index that describes your current working tree, and
-something you should be very aware of. Again, you normally never worry
-about the index file itself, but you should be aware of the fact that
-you have not actually really "checked in" your files into git so far,
-you've only *told* git about them.
-
-However, since git knows about them, you can now start using some of the
-most basic git commands to manipulate the files or look at their status.
-
-In particular, let's not even check in the two files into git yet, we'll
-start off by adding another line to `hello` first:
-
-------------------------------------------------
-$ echo "It's a new day for git" >>hello
-------------------------------------------------
-
-and you can now, since you told git about the previous state of `hello`, ask
-git what has changed in the tree compared to your old index, using the
-`git-diff-files` command:
-
-------------
-$ git-diff-files
-------------
-
-Oops. That wasn't very readable. It just spit out its own internal
-version of a `diff`, but that internal version really just tells you
-that it has noticed that "hello" has been modified, and that the old object
-contents it had have been replaced with something else.
-
-To make it readable, we can tell git-diff-files to output the
-differences as a patch, using the `-p` flag:
-
-------------
-$ git-diff-files -p
-diff --git a/hello b/hello

-i.e. the diff of the change we caused by adding another line to `hello`.
-
-In other words, `git-diff-files` always shows us the difference between
-what is recorded in the index, and what is currently in the working
-tree. That's very useful.
-
-A common shorthand for `git-diff-files -p` is to just write `git
-diff`, which will do the same thing.

-Committing git state
---------------------
-
-Now, we want to go to the next stage in git, which is to take the files
-that git knows about in the index, and commit them as a real tree. We do
-that in two phases: creating a 'tree' object, and committing that 'tree'
-object as a 'commit' object together with an explanation of what the
-tree was all about, along with information of how we came to that state.
-
-Creating a tree object is trivial, and is done with `git-write-tree`.
-There are no options or other input: git-write-tree will take the
-current index state, and write an object that describes that whole
-index. In other words, we're now tying together all the different
-filenames with their contents (and their permissions), and we're
-creating the equivalent of a git "directory" object:
-
-------------------------------------------------
-$ git-write-tree
-------------------------------------------------
-
-and this will just output the name of the resulting tree, in this case
-(if you have done exactly as I've described) it should be
-
-----------------
-8988da15d077d4829fc51d8544c097def6644dbb
-----------------
-
-which is another incomprehensible object name. Again, if you want to,
-you can use `git-cat-file -t 8988d\...` to see that this time the object
-is not a "blob" object, but a "tree" object (you can also use
-`git-cat-file` to actually output the raw object contents, but you'll see
-mainly a binary mess, so that's less interesting).
-
-However -- normally you'd never use `git-write-tree` on its own, because
-normally you always commit a tree into a commit object using the
-`git-commit-tree` command. In fact, it's easier to not actually use
-`git-write-tree` on its own at all, but to just pass its result in as an
-argument to `git-commit-tree`.
-
-`git-commit-tree` normally takes several arguments -- it wants to know
-what the 'parent' of a commit was, but since this is the first commit
-ever in this new repository, and it has no parents, we only need to pass in
-the object name of the tree. However, `git-commit-tree` also wants to get a
-commit message on its standard input, and it will write out the resulting
-object name for the commit to its standard output.
-
-And this is where we create the `.git/refs/heads/master` file
-which is pointed at by `HEAD`. This file is supposed to contain
-the reference to the top-of-tree of the master branch, and since
-that's exactly what `git-commit-tree` spits out, we can do this
-all with a sequence of simple shell commands:
-
-------------------------------------------------
-$ tree=$(git-write-tree)
-$ commit=$(echo 'Initial commit' | git-commit-tree $tree)
-$ git-update-ref HEAD $commit
-------------------------------------------------
-
-In this case this creates a totally new commit that is not related to
-anything else. Normally you do this only *once* for a project ever, and
-all later commits will be parented on top of an earlier commit.
-
-Again, normally you'd never actually do this by hand. There is a
-helpful script called `git commit` that will do all of this for you. So
-you could have just written `git commit`
-instead, and it would have done the above magic scripting for you.
-
-
-Making a change
----------------
-
-Remember how we did the `git-update-index` on file `hello` and then we
-changed `hello` afterward, and could compare the new state of `hello` with the
-state we saved in the index file?
-
-Further, remember how I said that `git-write-tree` writes the contents
-of the *index* file to the tree, and thus what we just committed was in
-fact the *original* contents of the file `hello`, not the new ones. We did
-that on purpose, to show the difference between the index state, and the
-state in the working tree, and how they don't have to match, even
-when we commit things.
-
-As before, if we do `git-diff-files -p` in our git-tutorial project,
-we'll still see the same difference we saw last time: the index file
-hasn't changed by the act of committing anything. However, now that we
-have committed something, we can also learn to use a new command:
-`git-diff-index`.
-
-Unlike `git-diff-files`, which showed the difference between the index
-file and the working tree, `git-diff-index` shows the differences
-between a committed *tree* and either the index file or the working
-tree. In other words, `git-diff-index` wants a tree to be diffed
-against, and before we did the commit, we couldn't do that, because we
-didn't have anything to diff against.
-
-But now we can do
-
-----------------
-$ git-diff-index -p HEAD
-----------------
-
-(where `-p` has the same meaning as it did in `git-diff-files`), and it
-will show us the same difference, but for a totally different reason.
-Now we're comparing the working tree not against the index file,
-but against the tree we just wrote. It just so happens that those two
-are obviously the same, so we get the same result.
-
-Again, because this is a common operation, you can also just shorthand
-it with
-
-----------------
-$ git diff HEAD
-----------------
-
-which ends up doing the above for you.
-
-In other words, `git-diff-index` normally compares a tree against the
-working tree, but when given the `\--cached` flag, it is told to
-instead compare against just the index cache contents, and ignore the
-current working tree state entirely. Since we just wrote the index
-file to HEAD, doing `git-diff-index \--cached -p HEAD` should thus return
-an empty set of differences, and that's exactly what it does.
-
-[NOTE]
-================
-`git-diff-index` really always uses the index for its
-comparisons, and saying that it compares a tree against the working
-tree is thus not strictly accurate. In particular, the list of
-files to compare (the "meta-data") *always* comes from the index file,
-regardless of whether the `\--cached` flag is used or not. The `\--cached`
-flag really only determines whether the file *contents* to be compared
-come from the working tree or not.
-
-This is not hard to understand, as soon as you realize that git simply
-never knows (or cares) about files that it is not told about
-explicitly. git will never go *looking* for files to compare, it
-expects you to tell it what the files are, and that's what the index
-is there for.
-================
-
-However, our next step is to commit the *change* we did, and again, to
-understand what's going on, keep in mind the difference between "working
-tree contents", "index file" and "committed tree". We have changes
-in the working tree that we want to commit, and we always have to
-work through the index file, so the first thing we need to do is to
-update the index cache:
-
-------------------------------------------------
-$ git-update-index hello
-------------------------------------------------
-
-(note how we didn't need the `\--add` flag this time, since git knew
-about the file already).
-
-Note what happens to the different `git-diff-\*` versions here. After
-we've updated `hello` in the index, `git-diff-files -p` now shows no
-differences, but `git-diff-index -p HEAD` still *does* show that the
-current state is different from the state we committed. In fact, now
-`git-diff-index` shows the same difference whether we use the `--cached`
-flag or not, since now the index is coherent with the working tree.
-
-Now, since we've updated `hello` in the index, we can commit the new
-version. We could do it by writing the tree by hand again, and
-committing the tree (this time we'd have to use the `-p HEAD` flag to
-tell commit that the HEAD was the *parent* of the new commit, and that
-this wasn't an initial commit any more), but you've done that once
-already, so let's just use the helpful script this time:
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-which starts an editor for you to write the commit message and tells you
-a bit about what you have done.
-
-Write whatever message you want, and all the lines that start with '#'
-will be pruned out, and the rest will be used as the commit message for
-the change. If you decide you don't want to commit anything after all at
-this point (you can continue to edit things and update the index), you
-can just leave an empty message. Otherwise `git commit` will commit
-the change for you.
-
-You've now made your first real git commit. And if you're interested in
-looking at what `git commit` really does, feel free to investigate:
-it's a few very simple shell scripts to generate the helpful (?) commit
-message headers, and a few one-liners that actually do the
-commit itself (`git-commit`).
-
-
-Inspecting Changes
-------------------
-
-While creating changes is useful, it's even more useful if you can tell
-later what changed. The most useful command for this is another of the
-`diff` family, namely `git-diff-tree`.
-
-`git-diff-tree` can be given two arbitrary trees, and it will tell you the
-differences between them. Perhaps even more commonly, though, you can
-give it just a single commit object, and it will figure out the parent
-of that commit itself, and show the difference directly. Thus, to get
-the same diff that we've already seen several times, we can now do
-
-----------------
-$ git-diff-tree -p HEAD
-----------------
-
-(again, `-p` means to show the difference as a human-readable patch),
-and it will show what the last commit (in `HEAD`) actually changed.
-

-============
-
-More interestingly, you can also give `git-diff-tree` the `--pretty` flag,
-which tells it to also show the commit message and author and date of the
-commit, and you can tell it to show a whole series of diffs.
-Alternatively, you can tell it to be "silent", and not show the diffs at
-all, but just show the actual commit message.
-
-In fact, together with the `git-rev-list` program (which generates a
-list of revisions), `git-diff-tree` ends up being a veritable fount of
-changes. A trivial (but very useful) script called `git-whatchanged` is
-included with git which does exactly this, and shows a log of recent
-activities.
-
-To see the whole history of our pitiful little git-tutorial project, you
-can do
-
-----------------
-$ git log
-----------------
-
-which shows just the log messages, or if we want to see the log together
-with the associated patches use the more complex (and much more
-powerful)
-
-----------------
-$ git-whatchanged -p --root
-----------------
-
-and you will see exactly what has changed in the repository over its
-short history.
-
-[NOTE]
-The `\--root` flag is a flag to `git-diff-tree` to tell it to
-show the initial aka 'root' commit too. Normally you'd probably not
-want to see the initial import diff, but since the tutorial project
-was started from scratch and is so small, we use it to make the result
-a bit more interesting.
-
-With that, you should now be having some inkling of what git does, and
-can explore on your own.
-
-[NOTE]
-Most likely, you are not directly using the core
-git Plumbing commands, but using Porcelain such as `git-add`, `git-rm'
-and `git-commit'.
-
-
-Tagging a version
------------------
-
-In git, there are two kinds of tags, a "light" one, and an "annotated tag".
-
-A "light" tag is technically nothing more than a branch, except we put
-it in the `.git/refs/tags/` subdirectory instead of calling it a `head`.
-So the simplest form of tag involves nothing more than
-
-------------------------------------------------
-$ git tag my-first-tag
-------------------------------------------------
-
-which just writes the current `HEAD` into the `.git/refs/tags/my-first-tag`
-file, after which point you can then use this symbolic name for that
-particular state. You can, for example, do
-
-----------------
-$ git diff my-first-tag
-----------------
-
-to diff your current state against that tag which at this point will
-obviously be an empty diff, but if you continue to develop and commit
-stuff, you can use your tag as an "anchor-point" to see what has changed
-since you tagged it.
-
-An "annotated tag" is actually a real git object, and contains not only a
-pointer to the state you want to tag, but also a small tag name and
-message, along with optionally a PGP signature that says that yes,
-you really did
-that tag. You create these annotated tags with either the `-a` or
-`-s` flag to `git tag`:
-
-----------------
-$ git tag -s <tagname>
-----------------
-
-which will sign the current `HEAD` (but you can also give it another
-argument that specifies the thing to tag, i.e., you could have tagged the
-current `mybranch` point by using `git tag <tagname> mybranch`).
-
-You normally only do signed tags for major releases or things
-like that, while the light-weight tags are useful for any marking you
-want to do -- any time you decide that you want to remember a certain
-point, just create a private tag for it, and you have a nice symbolic
-name for the state at that point.
-
-
-Copying repositories
---------------------
-
-git repositories are normally totally self-sufficient and relocatable.
-Unlike CVS, for example, there is no separate notion of
-"repository" and "working tree". A git repository normally *is* the
-working tree, with the local git information hidden in the `.git`
-subdirectory. There is nothing else. What you see is what you got.
-
-[NOTE]
-You can tell git to split the git internal information from
-the directory that it tracks, but we'll ignore that for now: it's not
-how normal projects work, and it's really only meant for special uses.
-So the mental model of "the git information is always tied directly to
-the working tree that it describes" may not be technically 100%
-accurate, but it's a good model for all normal use.
-
-This has two implications:
-
- - if you grow bored with the tutorial repository you created (or you've
-   made a mistake and want to start all over), you can just do simple
-+
-----------------
-$ rm -rf git-tutorial
-----------------
-+
-and it will be gone. There's no external repository, and there's no
-history outside the project you created.
-
- - if you want to move or duplicate a git repository, you can do so. There
-   is `git clone` command, but if all you want to do is just to
-   create a copy of your repository (with all the full history that
-   went along with it), you can do so with a regular
-   `cp -a git-tutorial new-git-tutorial`.
-+
-Note that when you've moved or copied a git repository, your git index
-file (which caches various information, notably some of the "stat"
-information for the files involved) will likely need to be refreshed.
-So after you do a `cp -a` to create a new copy, you'll want to do
-+
-----------------
-$ git-update-index --refresh
-----------------
-+
-in the new repository to make sure that the index file is up-to-date.
-
-Note that the second point is true even across machines. You can
-duplicate a remote git repository with *any* regular copy mechanism, be it
-`scp`, `rsync` or `wget`.
-
-When copying a remote repository, you'll want to at a minimum update the
-index cache when you do this, and especially with other peoples'
-repositories you often want to make sure that the index cache is in some
-known state (you don't know *what* they've done and not yet checked in),
-so usually you'll precede the `git-update-index` with a
-
-----------------
-$ git-read-tree --reset HEAD
-$ git-update-index --refresh
-----------------
-
-which will force a total index re-build from the tree pointed to by `HEAD`.
-It resets the index contents to `HEAD`, and then the `git-update-index`
-makes sure to match up all index entries with the checked-out files.
-If the original repository had uncommitted changes in its
-working tree, `git-update-index --refresh` notices them and
-tells you they need to be updated.
-
-The above can also be written as simply
-
-----------------
-$ git reset
-----------------
-
-and in fact a lot of the common git command combinations can be scripted
-with the `git xyz` interfaces.  You can learn things by just looking
-at what the various git scripts do.  For example, `git reset` used to be
-the above two lines implemented in `git-reset`, but some things like
-`git status` and `git commit` are slightly more complex scripts around
-the basic git commands.
-
-Many (most?) public remote repositories will not contain any of
-the checked out files or even an index file, and will *only* contain the
-actual core git files. Such a repository usually doesn't even have the
-`.git` subdirectory, but has all the git files directly in the
-repository.
-
-To create your own local live copy of such a "raw" git repository, you'd
-first create your own subdirectory for the project, and then copy the
-raw repository contents into the `.git` directory. For example, to
-create your own copy of the git repository, you'd do the following
-
-----------------
-$ mkdir my-git
-$ cd my-git
-$ rsync -rL rsync://rsync.kernel.org/pub/scm/git/git.git/ .git
-----------------
-
-followed by
-
-----------------
-$ git-read-tree HEAD
-----------------
-
-to populate the index. However, now you have populated the index, and
-you have all the git internal files, but you will notice that you don't
-actually have any of the working tree files to work on. To get
-those, you'd check them out with
-
-----------------
-$ git-checkout-index -u -a
-----------------
-
-where the `-u` flag means that you want the checkout to keep the index
-up-to-date (so that you don't have to refresh it afterward), and the
-`-a` flag means "check out all files" (if you have a stale copy or an
-older version of a checked out tree you may also need to add the `-f`
-flag first, to tell git-checkout-index to *force* overwriting of any old
-files).
-
-Again, this can all be simplified with
-
-----------------
-$ git clone rsync://rsync.kernel.org/pub/scm/git/git.git/ my-git
-$ cd my-git
-$ git checkout
-----------------
-
-which will end up doing all of the above for you.
-
-You have now successfully copied somebody else's (mine) remote
-repository, and checked it out.
-
-
-Creating a new branch
----------------------
-
-Branches in git are really nothing more than pointers into the git
-object database from within the `.git/refs/` subdirectory, and as we
-already discussed, the `HEAD` branch is nothing but a symlink to one of
-these object pointers.
-
-You can at any time create a new branch by just picking an arbitrary
-point in the project history, and just writing the SHA1 name of that
-object into a file under `.git/refs/heads/`. You can use any filename you
-want (and indeed, subdirectories), but the convention is that the
-"normal" branch is called `master`. That's just a convention, though,
-and nothing enforces it.
-
-To show that as an example, let's go back to the git-tutorial repository we
-used earlier, and create a branch in it. You do that by simply just
-saying that you want to check out a new branch:
-
-------------
-$ git checkout -b mybranch
-------------
-
-will create a new branch based at the current `HEAD` position, and switch
-to it.
-
-[NOTE]
-================================================
-If you make the decision to start your new branch at some
-other point in the history than the current `HEAD`, you can do so by
-just telling `git checkout` what the base of the checkout would be.
-In other words, if you have an earlier tag or branch, you'd just do
-
-------------
-$ git checkout -b mybranch earlier-commit
-------------
-
-and it would create the new branch `mybranch` at the earlier commit,
-and check out the state at that time.
-================================================
-
-You can always just jump back to your original `master` branch by doing
-
-------------
-$ git checkout master
-------------
-
-(or any other branch-name, for that matter) and if you forget which
-branch you happen to be on, a simple
-
-------------
-$ cat .git/HEAD
-------------
-
-will tell you where it's pointing.  To get the list of branches
-you have, you can say
-
-------------
-$ git branch
-------------
-
-which used to be nothing more than a simple script around `ls .git/refs/heads`.
-There will be an asterisk in front of the branch you are currently on.
-
-Sometimes you may wish to create a new branch _without_ actually
-checking it out and switching to it. If so, just use the command
-
-------------
-$ git branch <branchname> [startingpoint]
-------------
-
-which will simply _create_ the branch, but will not do anything further.
-You can then later -- once you decide that you want to actually develop
-on that branch -- switch to that branch with a regular `git checkout`
-with the branchname as the argument.
-
-
-Merging two branches
---------------------
-
-One of the ideas of having a branch is that you do some (possibly
-experimental) work in it, and eventually merge it back to the main
-branch. So assuming you created the above `mybranch` that started out
-being the same as the original `master` branch, let's make sure we're in
-that branch, and do some work there.
-
-------------------------------------------------
-$ git checkout mybranch
-$ echo "Work, work, work" >>hello
-$ git commit -m "Some work." -i hello
-------------------------------------------------
-
-Here, we just added another line to `hello`, and we used a shorthand for
-doing both `git-update-index hello` and `git commit` by just giving the
-filename directly to `git commit`, with an `-i` flag (it tells
-git to 'include' that file in addition to what you have done to
-the index file so far when making the commit).  The `-m` flag is to give the
-commit log message from the command line.
-
-Now, to make it a bit more interesting, let's assume that somebody else
-does some work in the original branch, and simulate that by going back
-to the master branch, and editing the same file differently there:
-
-------------
-$ git checkout master
-------------
-
-Here, take a moment to look at the contents of `hello`, and notice how they
-don't contain the work we just did in `mybranch` -- because that work
-hasn't happened in the `master` branch at all. Then do
-
-------------
-$ echo "Play, play, play" >>hello
-$ echo "Lots of fun" >>example
-$ git commit -m "Some fun." -i hello example
-------------
-
-since the master branch is obviously in a much better mood.
-
-Now, you've got two branches, and you decide that you want to merge the
-work done. Before we do that, let's introduce a cool graphical tool that
-helps you view what's going on:
-
-----------------
-$ gitk --all
-----------------
-
-will show you graphically both of your branches (that's what the `\--all`
-means: normally it will just show you your current `HEAD`) and their
-histories. You can also see exactly how they came to be from a common
-source.
-
-Anyway, let's exit `gitk` (`^Q` or the File menu), and decide that we want
-to merge the work we did on the `mybranch` branch into the `master`
-branch (which is currently our `HEAD` too). To do that, there's a nice
-script called `git merge`, which wants to know which branches you want
-to resolve and what the merge is all about:
-
-------------
-$ git merge -m "Merge work in mybranch" mybranch
-------------
-
-where the first argument is going to be used as the commit message if
-the merge can be resolved automatically.
-
-Now, in this case we've intentionally created a situation where the
-merge will need to be fixed up by hand, though, so git will do as much
-of it as it can automatically (which in this case is just merge the `example`
-file, which had no differences in the `mybranch` branch), and say:
-
-----------------
-       Auto-merging hello
-       CONFLICT (content): Merge conflict in hello
-       Automatic merge failed; fix up by hand
-----------------
-
-It tells you that it did an "Automatic merge", which
-failed due to conflicts in `hello`.
-
-Not to worry. It left the (trivial) conflict in `hello` in the same form you
-should already be well used to if you've ever used CVS, so let's just
-open `hello` in our editor (whatever that may be), and fix it up somehow.
-I'd suggest just making it so that `hello` contains all four lines:

-Hello World
-It's a new day for git
-Play, play, play
-Work, work, work
-------------
-
-and once you're happy with your manual merge, just do a
-
-------------
-$ git commit -i hello
-------------
-
-which will very loudly warn you that you're now committing a merge
-(which is correct, so never mind), and you can write a small merge
-message about your adventures in git-merge-land.
-
-After you're done, start up `gitk \--all` to see graphically what the
-history looks like. Notice that `mybranch` still exists, and you can
-switch to it, and continue to work with it if you want to. The
-`mybranch` branch will not contain the merge, but next time you merge it
-from the `master` branch, git will know how you merged it, so you'll not
-have to do _that_ merge again.
-
-Another useful tool, especially if you do not always work in X-Window
-environment, is `git show-branch`.
-
-------------------------------------------------
-$ git-show-branch --topo-order --more=1 master mybranch
-* [master] Merge work in mybranch
- ! [mybranch] Some work.
---
--  [master] Merge work in mybranch
-*+ [mybranch] Some work.
-*  [master^] Some fun.
-------------------------------------------------
-
-The first two lines indicate that it is showing the two branches
-and the first line of the commit log message from their
-top-of-the-tree commits, you are currently on `master` branch
-(notice the asterisk `\*` character), and the first column for
-the later output lines is used to show commits contained in the
-`master` branch, and the second column for the `mybranch`
-branch. Three commits are shown along with their log messages.
-All of them have non blank characters in the first column (`*`
-shows an ordinary commit on the current branch, `-` is a merge commit), which
-means they are now part of the `master` branch. Only the "Some
-work" commit has the plus `+` character in the second column,
-because `mybranch` has not been merged to incorporate these
-commits from the master branch.  The string inside brackets
-before the commit log message is a short name you can use to
-name the commit.  In the above example, 'master' and 'mybranch'
-are branch heads.  'master^' is the first parent of 'master'
-branch head.  Please see 'git-rev-parse' documentation if you
-see more complex cases.
-
-[NOTE]
-Without the '--more=1' option, 'git-show-branch' would not output the
-'[master^]' commit, as '[mybranch]' commit is a common ancestor of
-both 'master' and 'mybranch' tips.  Please see 'git-show-branch'
-documentation for details.
-
-[NOTE]
-If there were more commits on the 'master' branch after the merge, the
-merge commit itself would not be shown by 'git-show-branch' by
-default.  You would need to provide '--sparse' option to make the
-merge commit visible in this case.
-
-Now, let's pretend you are the one who did all the work in
-`mybranch`, and the fruit of your hard work has finally been merged
-to the `master` branch. Let's go back to `mybranch`, and run
-`git merge` to get the "upstream changes" back to your branch.
-
-------------
-$ git checkout mybranch
-$ git merge -m "Merge upstream changes." master
-------------
-
-This outputs something like this (the actual commit object names
-would be different)
-
-----------------
-Updating from ae3a2da... to a80b4aa....
-Fast forward
- example |    1 +
- hello   |    1 +
- 2 files changed, 2 insertions(+), 0 deletions(-)
-----------------
-
-Because your branch did not contain anything more than what are
-already merged into the `master` branch, the merge operation did
-not actually do a merge. Instead, it just updated the top of
-the tree of your branch to that of the `master` branch. This is
-often called 'fast forward' merge.
-
-You can run `gitk \--all` again to see how the commit ancestry
-looks like, or run `show-branch`, which tells you this.
-
-------------------------------------------------
-$ git show-branch master mybranch
-! [master] Merge work in mybranch
- * [mybranch] Merge work in mybranch
---
--- [master] Merge work in mybranch
-------------------------------------------------
-
-
-Merging external work
----------------------
-
-It's usually much more common that you merge with somebody else than
-merging with your own branches, so it's worth pointing out that git
-makes that very easy too, and in fact, it's not that different from
-doing a `git merge`. In fact, a remote merge ends up being nothing
-more than "fetch the work from a remote repository into a temporary tag"
-followed by a `git merge`.
-
-Fetching from a remote repository is done by, unsurprisingly,
-`git fetch`:
-
-----------------
-$ git fetch <remote-repository>
-----------------
-
-One of the following transports can be used to name the
-repository to download from:
-
-Rsync::
-       `rsync://remote.machine/path/to/repo.git/`
-+
-Rsync transport is usable for both uploading and downloading,
-but is completely unaware of what git does, and can produce
-unexpected results when you download from the public repository
-while the repository owner is uploading into it via `rsync`
-transport.  Most notably, it could update the files under
-`refs/` which holds the object name of the topmost commits
-before uploading the files in `objects/` -- the downloader would
-obtain head commit object name while that object itself is still
-not available in the repository.  For this reason, it is
-considered deprecated.
-
-SSH::
-       `remote.machine:/path/to/repo.git/` or
-+
-`ssh://remote.machine/path/to/repo.git/`
-+
-This transport can be used for both uploading and downloading,
-and requires you to have a log-in privilege over `ssh` to the
-remote machine.  It finds out the set of objects the other side
-lacks by exchanging the head commits both ends have and
-transfers (close to) minimum set of objects.  It is by far the
-most efficient way to exchange git objects between repositories.
-
-Local directory::
-       `/path/to/repo.git/`
-+
-This transport is the same as SSH transport but uses `sh` to run
-both ends on the local machine instead of running other end on
-the remote machine via `ssh`.
-
-git Native::
-       `git://remote.machine/path/to/repo.git/`
-+
-This transport was designed for anonymous downloading.  Like SSH
-transport, it finds out the set of objects the downstream side
-lacks and transfers (close to) minimum set of objects.
-
-HTTP(S)::
-       `http://remote.machine/path/to/repo.git/`
-+
-Downloader from http and https URL
-first obtains the topmost commit object name from the remote site
-by looking at the specified refname under `repo.git/refs/` directory,
-and then tries to obtain the
-commit object by downloading from `repo.git/objects/xx/xxx\...`
-using the object name of that commit object.  Then it reads the
-commit object to find out its parent commits and the associate
-tree object; it repeats this process until it gets all the
-necessary objects.  Because of this behavior, they are
-sometimes also called 'commit walkers'.
-+
-The 'commit walkers' are sometimes also called 'dumb
-transports', because they do not require any git aware smart
-server like git Native transport does.  Any stock HTTP server
-that does not even support directory index would suffice.  But
-you must prepare your repository with `git-update-server-info`
-to help dumb transport downloaders.
-
-Once you fetch from the remote repository, you `merge` that
-with your current branch.
-
-However -- it's such a common thing to `fetch` and then
-immediately `merge`, that it's called `git pull`, and you can
-simply do
-
-----------------
-$ git pull <remote-repository>
-----------------
-
-and optionally give a branch-name for the remote end as a second
-argument.
-
-[NOTE]
-You could do without using any branches at all, by
-keeping as many local repositories as you would like to have
-branches, and merging between them with `git pull`, just like
-you merge between branches. The advantage of this approach is
-that it lets you keep a set of files for each `branch` checked
-out and you may find it easier to switch back and forth if you
-juggle multiple lines of development simultaneously. Of
-course, you will pay the price of more disk usage to hold
-multiple working trees, but disk space is cheap these days.
-
-It is likely that you will be pulling from the same remote
-repository from time to time. As a short hand, you can store
-the remote repository URL in the local repository's config file
-like this:
-
-------------------------------------------------
-$ git config remote.linus.url http://www.kernel.org/pub/scm/git/git.git/
-------------------------------------------------
-
-and use the "linus" keyword with `git pull` instead of the full URL.
-
-Examples.
-
-. `git pull linus`
-. `git pull linus tag v0.99.1`
-
-the above are equivalent to:
-
-. `git pull http://www.kernel.org/pub/scm/git/git.git/ HEAD`
-. `git pull http://www.kernel.org/pub/scm/git/git.git/ tag v0.99.1`
-
-
-How does the merge work?
-------------------------
-
-We said this tutorial shows what plumbing does to help you cope
-with the porcelain that isn't flushing, but we so far did not
-talk about how the merge really works.  If you are following
-this tutorial the first time, I'd suggest to skip to "Publishing
-your work" section and come back here later.
-
-OK, still with me?  To give us an example to look at, let's go
-back to the earlier repository with "hello" and "example" file,
-and bring ourselves back to the pre-merge state:
-
-------------
-$ git show-branch --more=2 master mybranch
-! [master] Merge work in mybranch
- * [mybranch] Merge work in mybranch
---
--- [master] Merge work in mybranch
-+* [master^2] Some work.
-+* [master^] Some fun.
-------------
-
-Remember, before running `git merge`, our `master` head was at
-"Some fun." commit, while our `mybranch` head was at "Some
-work." commit.
-
-------------
-$ git checkout mybranch
-$ git reset --hard master^2
-$ git checkout master
-$ git reset --hard master^
-------------
-
-After rewinding, the commit structure should look like this:
-
-------------
-$ git show-branch
-* [master] Some fun.
- ! [mybranch] Some work.
---
- + [mybranch] Some work.
-*  [master] Some fun.
-*+ [mybranch^] New day.
-------------
-
-Now we are ready to experiment with the merge by hand.
-
-`git merge` command, when merging two branches, uses 3-way merge
-algorithm.  First, it finds the common ancestor between them.
-The command it uses is `git-merge-base`:
-
-------------
-$ mb=$(git-merge-base HEAD mybranch)
-------------
-
-The command writes the commit object name of the common ancestor
-to the standard output, so we captured its output to a variable,
-because we will be using it in the next step.  By the way, the common
-ancestor commit is the "New day." commit in this case.  You can
-tell it by:
-
-------------
-$ git-name-rev $mb
-my-first-tag
-------------
-
-After finding out a common ancestor commit, the second step is
-this:
-
-------------
-$ git-read-tree -m -u $mb HEAD mybranch
-------------
-
-This is the same `git-read-tree` command we have already seen,
-but it takes three trees, unlike previous examples.  This reads
-the contents of each tree into different 'stage' in the index
-file (the first tree goes to stage 1, the second to stage 2,
-etc.).  After reading three trees into three stages, the paths
-that are the same in all three stages are 'collapsed' into stage
-0.  Also paths that are the same in two of three stages are
-collapsed into stage 0, taking the SHA1 from either stage 2 or
-stage 3, whichever is different from stage 1 (i.e. only one side
-changed from the common ancestor).
-
-After 'collapsing' operation, paths that are different in three
-trees are left in non-zero stages.  At this point, you can
-inspect the index file with this command:
-
-------------
-$ git-ls-files --stage
-100644 7f8b141b65fdcee47321e399a2598a235a032422 0      example
-100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1      hello
-100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2      hello
-100644 cc44c73eb783565da5831b4d820c962954019b69 3      hello
-------------
-
-In our example of only two files, we did not have unchanged
-files so only 'example' resulted in collapsing, but in real-life
-large projects, only small number of files change in one commit,
-and this 'collapsing' tends to trivially merge most of the paths
-fairly quickly, leaving only a handful the real changes in non-zero
-stages.
-
-To look at only non-zero stages, use `\--unmerged` flag:
-
-------------
-$ git-ls-files --unmerged
-100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1      hello
-100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2      hello
-100644 cc44c73eb783565da5831b4d820c962954019b69 3      hello
-------------
-
-The next step of merging is to merge these three versions of the
-file, using 3-way merge.  This is done by giving
-`git-merge-one-file` command as one of the arguments to
-`git-merge-index` command:
-
-------------
-$ git-merge-index git-merge-one-file hello
-Auto-merging hello.
-merge: warning: conflicts during merge
-ERROR: Merge conflict in hello.
-fatal: merge program failed
-------------
-
-`git-merge-one-file` script is called with parameters to
-describe those three versions, and is responsible to leave the
-merge results in the working tree.
-It is a fairly straightforward shell script, and
-eventually calls `merge` program from RCS suite to perform a
-file-level 3-way merge.  In this case, `merge` detects
-conflicts, and the merge result with conflict marks is left in
-the working tree..  This can be seen if you run `ls-files
---stage` again at this point:
-
-------------
-$ git-ls-files --stage
-100644 7f8b141b65fdcee47321e399a2598a235a032422 0      example
-100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1      hello
-100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2      hello
-100644 cc44c73eb783565da5831b4d820c962954019b69 3      hello
-------------
-
-This is the state of the index file and the working file after
-`git merge` returns control back to you, leaving the conflicting
-merge for you to resolve.  Notice that the path `hello` is still
-unmerged, and what you see with `git diff` at this point is
-differences since stage 2 (i.e. your version).
-
-
-Publishing your work
---------------------
-
-So, we can use somebody else's work from a remote repository, but
-how can *you* prepare a repository to let other people pull from
-it?
-
-You do your real work in your working tree that has your
-primary repository hanging under it as its `.git` subdirectory.
-You *could* make that repository accessible remotely and ask
-people to pull from it, but in practice that is not the way
-things are usually done. A recommended way is to have a public
-repository, make it reachable by other people, and when the
-changes you made in your primary working tree are in good shape,
-update the public repository from it. This is often called
-'pushing'.
-
-[NOTE]
-This public repository could further be mirrored, and that is
-how git repositories at `kernel.org` are managed.
-
-Publishing the changes from your local (private) repository to
-your remote (public) repository requires a write privilege on
-the remote machine. You need to have an SSH account there to
-run a single command, `git-receive-pack`.
-
-First, you need to create an empty repository on the remote
-machine that will house your public repository. This empty
-repository will be populated and be kept up-to-date by pushing
-into it later. Obviously, this repository creation needs to be
-done only once.
-
-[NOTE]
-`git push` uses a pair of programs,
-`git-send-pack` on your local machine, and `git-receive-pack`
-on the remote machine. The communication between the two over
-the network internally uses an SSH connection.
-
-Your private repository's git directory is usually `.git`, but
-your public repository is often named after the project name,
-i.e. `<project>.git`. Let's create such a public repository for
-project `my-git`. After logging into the remote machine, create
-an empty directory:
-
-------------
-$ mkdir my-git.git
-------------
-
-Then, make that directory into a git repository by running
-`git init`, but this time, since its name is not the usual
-`.git`, we do things slightly differently:
-
-------------
-$ GIT_DIR=my-git.git git-init
-------------
-
-Make sure this directory is available for others you want your
-changes to be pulled by via the transport of your choice. Also
-you need to make sure that you have the `git-receive-pack`
-program on the `$PATH`.
-
-[NOTE]
-Many installations of sshd do not invoke your shell as the login
-shell when you directly run programs; what this means is that if
-your login shell is `bash`, only `.bashrc` is read and not
-`.bash_profile`. As a workaround, make sure `.bashrc` sets up
-`$PATH` so that you can run `git-receive-pack` program.
-
-[NOTE]
-If you plan to publish this repository to be accessed over http,
-you should do `chmod +x my-git.git/hooks/post-update` at this
-point.  This makes sure that every time you push into this
-repository, `git-update-server-info` is run.
-
-Your "public repository" is now ready to accept your changes.
-Come back to the machine you have your private repository. From
-there, run this command:
-
-------------
-$ git push <public-host>:/path/to/my-git.git master
-------------
-
-This synchronizes your public repository to match the named
-branch head (i.e. `master` in this case) and objects reachable
-from them in your current repository.
-
-As a real example, this is how I update my public git
-repository. Kernel.org mirror network takes care of the
-propagation to other publicly visible machines:
-
-------------
-$ git push master.kernel.org:/pub/scm/git/git.git/
-------------
-
-
-Packing your repository
------------------------
-
-Earlier, we saw that one file under `.git/objects/??/` directory
-is stored for each git object you create. This representation
-is efficient to create atomically and safely, but
-not so convenient to transport over the network. Since git objects are
-immutable once they are created, there is a way to optimize the
-storage by "packing them together". The command
-
-------------
-$ git repack
-------------
-
-will do it for you. If you followed the tutorial examples, you
-would have accumulated about 17 objects in `.git/objects/??/`
-directories by now. `git repack` tells you how many objects it
-packed, and stores the packed file in `.git/objects/pack`
-directory.
-
-[NOTE]
-You will see two files, `pack-\*.pack` and `pack-\*.idx`,
-in `.git/objects/pack` directory. They are closely related to
-each other, and if you ever copy them by hand to a different
-repository for whatever reason, you should make sure you copy
-them together. The former holds all the data from the objects
-in the pack, and the latter holds the index for random
-access.
-
-If you are paranoid, running `git-verify-pack` command would
-detect if you have a corrupt pack, but do not worry too much.
-Our programs are always perfect ;-).
-
-Once you have packed objects, you do not need to leave the
-unpacked objects that are contained in the pack file anymore.
-
-------------
-$ git prune-packed
-------------
-
-would remove them for you.
-
-You can try running `find .git/objects -type f` before and after
-you run `git prune-packed` if you are curious.  Also `git
-count-objects` would tell you how many unpacked objects are in
-your repository and how much space they are consuming.
-
-[NOTE]
-`git pull` is slightly cumbersome for HTTP transport, as a
-packed repository may contain relatively few objects in a
-relatively large pack. If you expect many HTTP pulls from your
-public repository you might want to repack & prune often, or
-never.
-
-If you run `git repack` again at this point, it will say
-"Nothing to pack". Once you continue your development and
-accumulate the changes, running `git repack` again will create a
-new pack, that contains objects created since you packed your
-repository the last time. We recommend that you pack your project
-soon after the initial import (unless you are starting your
-project from scratch), and then run `git repack` every once in a
-while, depending on how active your project is.
-
-When a repository is synchronized via `git push` and `git pull`
-objects packed in the source repository are usually stored
-unpacked in the destination, unless rsync transport is used.
-While this allows you to use different packing strategies on
-both ends, it also means you may need to repack both
-repositories every once in a while.
-
-
-Working with Others
--------------------
-
-Although git is a truly distributed system, it is often
-convenient to organize your project with an informal hierarchy
-of developers. Linux kernel development is run this way. There
-is a nice illustration (page 17, "Merges to Mainline") in
-link:http://www.xenotime.net/linux/mentor/linux-mentoring-2006.pdf[Randy Dunlap's presentation].
-
-It should be stressed that this hierarchy is purely *informal*.
-There is nothing fundamental in git that enforces the "chain of
-patch flow" this hierarchy implies. You do not have to pull
-from only one remote repository.
-
-A recommended workflow for a "project lead" goes like this:
-
-1. Prepare your primary repository on your local machine. Your
-   work is done there.
-
-2. Prepare a public repository accessible to others.
-+
-If other people are pulling from your repository over dumb
-transport protocols (HTTP), you need to keep this repository
-'dumb transport friendly'.  After `git init`,
-`$GIT_DIR/hooks/post-update` copied from the standard templates
-would contain a call to `git-update-server-info` but the
-`post-update` hook itself is disabled by default -- enable it
-with `chmod +x post-update`.  This makes sure `git-update-server-info`
-keeps the necessary files up-to-date.
-
-3. Push into the public repository from your primary
-   repository.
-
-4. `git repack` the public repository. This establishes a big
-   pack that contains the initial set of objects as the
-   baseline, and possibly `git prune` if the transport
-   used for pulling from your repository supports packed
-   repositories.
-
-5. Keep working in your primary repository. Your changes
-   include modifications of your own, patches you receive via
-   e-mails, and merges resulting from pulling the "public"
-   repositories of your "subsystem maintainers".
-+
-You can repack this private repository whenever you feel like.
-
-6. Push your changes to the public repository, and announce it
-   to the public.
-
-7. Every once in a while, "git repack" the public repository.
-   Go back to step 5. and continue working.
-
-
-A recommended work cycle for a "subsystem maintainer" who works
-on that project and has an own "public repository" goes like this:
-
-1. Prepare your work repository, by `git clone` the public
-   repository of the "project lead". The URL used for the
-   initial cloning is stored in the remote.origin.url
-   configuration variable.
-
-2. Prepare a public repository accessible to others, just like
-   the "project lead" person does.
-
-3. Copy over the packed files from "project lead" public
-   repository to your public repository, unless the "project
-   lead" repository lives on the same machine as yours.  In the
-   latter case, you can use `objects/info/alternates` file to
-   point at the repository you are borrowing from.
-
-4. Push into the public repository from your primary
-   repository. Run `git repack`, and possibly `git prune` if the
-   transport used for pulling from your repository supports
-   packed repositories.
-
-5. Keep working in your primary repository. Your changes
-   include modifications of your own, patches you receive via
-   e-mails, and merges resulting from pulling the "public"
-   repositories of your "project lead" and possibly your
-   "sub-subsystem maintainers".
-+
-You can repack this private repository whenever you feel
-like.
-
-6. Push your changes to your public repository, and ask your
-   "project lead" and possibly your "sub-subsystem
-   maintainers" to pull from it.
-
-7. Every once in a while, `git repack` the public repository.
-   Go back to step 5. and continue working.
-
-
-A recommended work cycle for an "individual developer" who does
-not have a "public" repository is somewhat different. It goes
-like this:
-
-1. Prepare your work repository, by `git clone` the public
-   repository of the "project lead" (or a "subsystem
-   maintainer", if you work on a subsystem). The URL used for
-   the initial cloning is stored in the remote.origin.url
-   configuration variable.
-
-2. Do your work in your repository on 'master' branch.
-
-3. Run `git fetch origin` from the public repository of your
-   upstream every once in a while. This does only the first
-   half of `git pull` but does not merge. The head of the
-   public repository is stored in `.git/refs/remotes/origin/master`.
-
-4. Use `git cherry origin` to see which ones of your patches
-   were accepted, and/or use `git rebase origin` to port your
-   unmerged changes forward to the updated upstream.
-
-5. Use `git format-patch origin` to prepare patches for e-mail
-   submission to your upstream and send it out. Go back to
-   step 2. and continue.
-
-
-Working with Others, Shared Repository Style
---------------------------------------------
-
-If you are coming from CVS background, the style of cooperation
-suggested in the previous section may be new to you. You do not
-have to worry. git supports "shared public repository" style of
-cooperation you are probably more familiar with as well.
-
-See link:cvs-migration.html[git for CVS users] for the details.
-
-Bundling your work together
----------------------------
-
-It is likely that you will be working on more than one thing at
-a time.  It is easy to manage those more-or-less independent tasks
-using branches with git.
-
-We have already seen how branches work previously,
-with "fun and work" example using two branches.  The idea is the
-same if there are more than two branches.  Let's say you started
-out from "master" head, and have some new code in the "master"
-branch, and two independent fixes in the "commit-fix" and
-"diff-fix" branches:
-
-------------
-$ git show-branch
-! [commit-fix] Fix commit message normalization.
- ! [diff-fix] Fix rename detection.
-  * [master] Release candidate #1
----
- +  [diff-fix] Fix rename detection.
- +  [diff-fix~1] Better common substring algorithm.
-+   [commit-fix] Fix commit message normalization.
-  * [master] Release candidate #1
-++* [diff-fix~2] Pretty-print messages.
-------------
-
-Both fixes are tested well, and at this point, you want to merge
-in both of them.  You could merge in 'diff-fix' first and then
-'commit-fix' next, like this:
-
-------------
-$ git merge -m "Merge fix in diff-fix" diff-fix
-$ git merge -m "Merge fix in commit-fix" commit-fix
-------------
-
-Which would result in:
-
-------------
-$ git show-branch
-! [commit-fix] Fix commit message normalization.
- ! [diff-fix] Fix rename detection.
-  * [master] Merge fix in commit-fix
----
-  - [master] Merge fix in commit-fix
-+ * [commit-fix] Fix commit message normalization.
-  - [master~1] Merge fix in diff-fix
- +* [diff-fix] Fix rename detection.
- +* [diff-fix~1] Better common substring algorithm.
-  * [master~2] Release candidate #1
-++* [master~3] Pretty-print messages.
-------------
-
-However, there is no particular reason to merge in one branch
-first and the other next, when what you have are a set of truly
-independent changes (if the order mattered, then they are not
-independent by definition).  You could instead merge those two
-branches into the current branch at once.  First let's undo what
-we just did and start over.  We would want to get the master
-branch before these two merges by resetting it to 'master~2':
-
-------------
-$ git reset --hard master~2
-------------
-
-You can make sure 'git show-branch' matches the state before
-those two 'git merge' you just did.  Then, instead of running
-two 'git merge' commands in a row, you would merge these two
-branch heads (this is known as 'making an Octopus'):
-
-------------
-$ git merge commit-fix diff-fix
-$ git show-branch
-! [commit-fix] Fix commit message normalization.
- ! [diff-fix] Fix rename detection.
-  * [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
----
-  - [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
-+ * [commit-fix] Fix commit message normalization.
- +* [diff-fix] Fix rename detection.
- +* [diff-fix~1] Better common substring algorithm.
-  * [master~1] Release candidate #1
-++* [master~2] Pretty-print messages.
-------------
-
-Note that you should not do Octopus because you can.  An octopus
-is a valid thing to do and often makes it easier to view the
-commit history if you are merging more than two independent
-changes at the same time.  However, if you have merge conflicts
-with any of the branches you are merging in and need to hand
-resolve, that is an indication that the development happened in
-those branches were not independent after all, and you should
-merge two at a time, documenting how you resolved the conflicts,
-and the reason why you preferred changes made in one side over
-the other.  Otherwise it would make the project history harder
-to follow, not easier.

-git for CVS users
-=================
-
-Git differs from CVS in that every working tree contains a repository with
-a full copy of the project history, and no repository is inherently more
-important than any other.  However, you can emulate the CVS model by
-designating a single shared repository which people can synchronize with;
-this document explains how to do that.
-
-Some basic familiarity with git is required.  This
-link:tutorial.html[tutorial introduction to git] should be sufficient.
-
-Developing against a shared repository
---------------------------------------
-
-Suppose a shared repository is set up in /pub/repo.git on the host
-foo.com.  Then as an individual committer you can clone the shared
-repository over ssh with:
-
-------------------------------------------------
-$ git clone foo.com:/pub/repo.git/ my-project
-$ cd my-project
-------------------------------------------------
-
-and hack away.  The equivalent of `cvs update` is
-
-------------------------------------------------
-$ git pull origin
-------------------------------------------------
-
-which merges in any work that others might have done since the clone
-operation.  If there are uncommitted changes in your working tree, commit
-them first before running git pull.
-
-[NOTE]
-================================
-The `pull` command knows where to get updates from because of certain
-configuration variables that were set by the first `git clone`
-command; see `git config -l` and the linkgit:git-config[1] man
-page for details.
-================================
-
-You can update the shared repository with your changes by first committing
-your changes, and then using the linkgit:git-push[1] command:
-
-------------------------------------------------
-$ git push origin master
-------------------------------------------------
-
-to "push" those commits to the shared repository.  If someone else has
-updated the repository more recently, `git push`, like `cvs commit`, will
-complain, in which case you must pull any changes before attempting the
-push again.
-
-In the `git push` command above we specify the name of the remote branch
-to update (`master`).  If we leave that out, `git push` tries to update
-any branches in the remote repository that have the same name as a branch
-in the local repository.  So the last `push` can be done with either of:
-
-------------
-$ git push origin
-$ git push foo.com:/pub/project.git/
-------------
-
-as long as the shared repository does not have any branches
-other than `master`.
-
-Setting Up a Shared Repository
-------------------------------
-
-We assume you have already created a git repository for your project,
-possibly created from scratch or from a tarball (see the
-link:tutorial.html[tutorial]), or imported from an already existing CVS
-repository (see the next section).
-
-Assume your existing repo is at /home/alice/myproject.  Create a new "bare"
-repository (a repository without a working tree) and fetch your project into
-it:
-
-------------------------------------------------
-$ mkdir /pub/my-repo.git
-$ cd /pub/my-repo.git
-$ git --bare init --shared
-$ git --bare fetch /home/alice/myproject master:master
-------------------------------------------------
-
-Next, give every team member read/write access to this repository.  One
-easy way to do this is to give all the team members ssh access to the
-machine where the repository is hosted.  If you don't want to give them a
-full shell on the machine, there is a restricted shell which only allows
-users to do git pushes and pulls; see linkgit:git-shell[1].
-
-Put all the committers in the same group, and make the repository
-writable by that group:
-
-------------------------------------------------
-$ chgrp -R $group /pub/my-repo.git
-------------------------------------------------
-
-Make sure committers have a umask of at most 027, so that the directories
-they create are writable and searchable by other group members.
-
-Importing a CVS archive
------------------------
-
-First, install version 2.1 or higher of cvsps from
-link:http://www.cobite.com/cvsps/[http://www.cobite.com/cvsps/] and make
-sure it is in your path.  Then cd to a checked out CVS working directory
-of the project you are interested in and run linkgit:git-cvsimport[1]:
-
--------------------------------------------
-$ git cvsimport -C <destination> <module>
--------------------------------------------
-
-This puts a git archive of the named CVS module in the directory
-<destination>, which will be created if necessary.
-
-The import checks out from CVS every revision of every file.  Reportedly
-cvsimport can average some twenty revisions per second, so for a
-medium-sized project this should not take more than a couple of minutes.
-Larger projects or remote repositories may take longer.
-
-The main trunk is stored in the git branch named `origin`, and additional
-CVS branches are stored in git branches with the same names.  The most
-recent version of the main trunk is also left checked out on the `master`
-branch, so you can start adding your own changes right away.
-
-The import is incremental, so if you call it again next month it will
-fetch any CVS updates that have been made in the meantime.  For this to
-work, you must not modify the imported branches; instead, create new
-branches for your own changes, and merge in the imported branches as
-necessary.
-
-Advanced Shared Repository Management
--------------------------------------
-
-Git allows you to specify scripts called "hooks" to be run at certain
-points.  You can use these, for example, to send all commits to the shared
-repository to a mailing list.  See link:hooks.html[Hooks used by git].
-
-You can enforce finer grained permissions using update hooks.  See
-link:howto/update-hook-example.txt[Controlling access to branches using
-update hooks].
-
-Providing CVS Access to a git Repository
-----------------------------------------
-
-It is also possible to provide true CVS access to a git repository, so
-that developers can still use CVS; see linkgit:git-cvsserver[1] for
-details.
-
-Alternative Development Models
-------------------------------
-
-CVS users are accustomed to giving a group of developers commit access to
-a common repository.  As we've seen, this is also possible with git.
-However, the distributed nature of git allows other development models,
-and you may want to first consider whether one of them might be a better
-fit for your project.
-
-For example, you can choose a single person to maintain the project's
-primary public repository.  Other developers then clone this repository
-and each work in their own clone.  When they have a series of changes that
-they're happy with, they ask the maintainer to pull from the branch
-containing the changes.  The maintainer reviews their changes and pulls
-them into the primary repository, which other developers pull from as
-necessary to stay coordinated.  The Linux kernel and other projects use
-variants of this model.
-
-With a small group, developers may just pull changes from each other's
-repositories without the need for a central maintainer.

-Tweaking diff output
-====================
-June 2005
-
-
-Introduction
-------------
-
-The diff commands git-diff-index, git-diff-files, and git-diff-tree
-can be told to manipulate differences they find in
-unconventional ways before showing diff(1) output.  The manipulation
-is collectively called "diffcore transformation".  This short note
-describes what they are and how to use them to produce diff outputs
-that are easier to understand than the conventional kind.
-
-
-The chain of operation
-----------------------
-
-The git-diff-* family works by first comparing two sets of
-files:
-
- - git-diff-index compares contents of a "tree" object and the
-   working directory (when '\--cached' flag is not used) or a
-   "tree" object and the index file (when '\--cached' flag is
-   used);
-
- - git-diff-files compares contents of the index file and the
-   working directory;
-
- - git-diff-tree compares contents of two "tree" objects;
-
-In all of these cases, the commands themselves compare
-corresponding paths in the two sets of files.  The result of
-comparison is passed from these commands to what is internally
-called "diffcore", in a format similar to what is output when
-the -p option is not used.  E.g.
-
-------------------------------------------------
-in-place edit  :100644 100644 bcd1234... 0123456... M file0
-create         :000000 100644 0000000... 1234567... A file4
-delete         :100644 000000 1234567... 0000000... D file5
-unmerged       :000000 000000 0000000... 0000000... U file6
-------------------------------------------------
-
-The diffcore mechanism is fed a list of such comparison results
-(each of which is called "filepair", although at this point each
-of them talks about a single file), and transforms such a list
-into another list.  There are currently 6 such transformations:
-
-- diffcore-pathspec
-- diffcore-break
-- diffcore-rename
-- diffcore-merge-broken
-- diffcore-pickaxe
-- diffcore-order
-
-These are applied in sequence.  The set of filepairs git-diff-\*
-commands find are used as the input to diffcore-pathspec, and
-the output from diffcore-pathspec is used as the input to the
-next transformation.  The final result is then passed to the
-output routine and generates either diff-raw format (see Output
-format sections of the manual for git-diff-\* commands) or
-diff-patch format.
-
-
-diffcore-pathspec: For Ignoring Files Outside Our Consideration
----------------------------------------------------------------
-
-The first transformation in the chain is diffcore-pathspec, and
-is controlled by giving the pathname parameters to the
-git-diff-* commands on the command line.  The pathspec is used
-to limit the world diff operates in.  It removes the filepairs
-outside the specified set of pathnames.  E.g. If the input set
-of filepairs included:
-
-------------------------------------------------
-:100644 100644 bcd1234... 0123456... M junkfile
-------------------------------------------------
-
-but the command invocation was "git-diff-files myfile", then the
-junkfile entry would be removed from the list because only "myfile"
-is under consideration.
-
-Implementation note.  For performance reasons, git-diff-tree
-uses the pathname parameters on the command line to cull set of
-filepairs it feeds the diffcore mechanism itself, and does not
-use diffcore-pathspec, but the end result is the same.
-
-
-diffcore-break: For Splitting Up "Complete Rewrites"
-----------------------------------------------------
-
-The second transformation in the chain is diffcore-break, and is
-controlled by the -B option to the git-diff-* commands.  This is
-used to detect a filepair that represents "complete rewrite" and
-break such filepair into two filepairs that represent delete and
-create.  E.g.  If the input contained this filepair:
-
-------------------------------------------------
-:100644 100644 bcd1234... 0123456... M file0
-------------------------------------------------
-
-and if it detects that the file "file0" is completely rewritten,
-it changes it to:
-
-------------------------------------------------
-:100644 000000 bcd1234... 0000000... D file0
-:000000 100644 0000000... 0123456... A file0
-------------------------------------------------
-
-For the purpose of breaking a filepair, diffcore-break examines
-the extent of changes between the contents of the files before
-and after modification (i.e. the contents that have "bcd1234..."
-and "0123456..." as their SHA1 content ID, in the above
-example).  The amount of deletion of original contents and
-insertion of new material are added together, and if it exceeds
-the "break score", the filepair is broken into two.  The break
-score defaults to 50% of the size of the smaller of the original
-and the result (i.e. if the edit shrinks the file, the size of
-the result is used; if the edit lengthens the file, the size of
-the original is used), and can be customized by giving a number
-after "-B" option (e.g. "-B75" to tell it to use 75%).
-
-
-diffcore-rename: For Detection Renames and Copies
--------------------------------------------------
-
-This transformation is used to detect renames and copies, and is
-controlled by the -M option (to detect renames) and the -C option
-(to detect copies as well) to the git-diff-* commands.  If the
-input contained these filepairs:
-
-------------------------------------------------
-:100644 000000 0123456... 0000000... D fileX
-:000000 100644 0000000... 0123456... A file0
-------------------------------------------------
-
-and the contents of the deleted file fileX is similar enough to
-the contents of the created file file0, then rename detection
-merges these filepairs and creates:
-
-------------------------------------------------
-:100644 100644 0123456... 0123456... R100 fileX file0
-------------------------------------------------
-
-When the "-C" option is used, the original contents of modified files,
-and deleted files (and also unmodified files, if the
-"\--find-copies-harder" option is used) are considered as candidates
-of the source files in rename/copy operation.  If the input were like
-these filepairs, that talk about a modified file fileY and a newly
-created file file0:
-
-------------------------------------------------
-:100644 100644 0123456... 1234567... M fileY
-:000000 100644 0000000... bcd3456... A file0
-------------------------------------------------
-
-the original contents of fileY and the resulting contents of
-file0 are compared, and if they are similar enough, they are
-changed to:
-
-------------------------------------------------
-:100644 100644 0123456... 1234567... M fileY
-:100644 100644 0123456... bcd3456... C100 fileY file0
-------------------------------------------------
-
-In both rename and copy detection, the same "extent of changes"
-algorithm used in diffcore-break is used to determine if two
-files are "similar enough", and can be customized to use
-a similarity score different from the default of 50% by giving a
-number after the "-M" or "-C" option (e.g. "-M8" to tell it to use
-8/10 = 80%).
-
-Note.  When the "-C" option is used with `\--find-copies-harder`
-option, git-diff-\* commands feed unmodified filepairs to
-diffcore mechanism as well as modified ones.  This lets the copy
-detector consider unmodified files as copy source candidates at
-the expense of making it slower.  Without `\--find-copies-harder`,
-git-diff-\* commands can detect copies only if the file that was
-copied happened to have been modified in the same changeset.
-
-
-diffcore-merge-broken: For Putting "Complete Rewrites" Back Together
---------------------------------------------------------------------
-
-This transformation is used to merge filepairs broken by
-diffcore-break, and not transformed into rename/copy by
-diffcore-rename, back into a single modification.  This always
-runs when diffcore-break is used.
-
-For the purpose of merging broken filepairs back, it uses a
-different "extent of changes" computation from the ones used by
-diffcore-break and diffcore-rename.  It counts only the deletion
-from the original, and does not count insertion.  If you removed
-only 10 lines from a 100-line document, even if you added 910
-new lines to make a new 1000-line document, you did not do a
-complete rewrite.  diffcore-break breaks such a case in order to
-help diffcore-rename to consider such filepairs as candidate of
-rename/copy detection, but if filepairs broken that way were not
-matched with other filepairs to create rename/copy, then this
-transformation merges them back into the original
-"modification".
-
-The "extent of changes" parameter can be tweaked from the
-default 80% (that is, unless more than 80% of the original
-material is deleted, the broken pairs are merged back into a
-single modification) by giving a second number to -B option,
-like these:
-
-* -B50/60 (give 50% "break score" to diffcore-break, use 60%
-  for diffcore-merge-broken).
-
-* -B/60 (the same as above, since diffcore-break defaults to 50%).
-
-Note that earlier implementation left a broken pair as a separate
-creation and deletion patches.  This was an unnecessary hack and
-the latest implementation always merges all the broken pairs
-back into modifications, but the resulting patch output is
-formatted differently for easier review in case of such
-a complete rewrite by showing the entire contents of old version
-prefixed with '-', followed by the entire contents of new
-version prefixed with '+'.
-
-
-diffcore-pickaxe: For Detecting Addition/Deletion of Specified String
----------------------------------------------------------------------
-
-This transformation is used to find filepairs that represent
-changes that touch a specified string, and is controlled by the
--S option and the `\--pickaxe-all` option to the git-diff-*
-commands.
-
-When diffcore-pickaxe is in use, it checks if there are
-filepairs whose "original" side has the specified string and
-whose "result" side does not.  Such a filepair represents "the
-string appeared in this changeset".  It also checks for the
-opposite case that loses the specified string.
-
-When `\--pickaxe-all` is not in effect, diffcore-pickaxe leaves
-only such filepairs that touch the specified string in its
-output.  When `\--pickaxe-all` is used, diffcore-pickaxe leaves all
-filepairs intact if there is such a filepair, or makes the
-output empty otherwise.  The latter behaviour is designed to
-make reviewing of the changes in the context of the whole
-changeset easier.
-
-
-diffcore-order: For Sorting the Output Based on Filenames
----------------------------------------------------------
-
-This is used to reorder the filepairs according to the user's
-(or project's) taste, and is controlled by the -O option to the
-git-diff-* commands.
-
-This takes a text file each of whose lines is a shell glob
-pattern.  Filepairs that match a glob pattern on an earlier line
-in the file are output before ones that match a later line, and
-filepairs that do not match any glob pattern are output last.
-
-As an example, a typical orderfile for the core git probably
-would look like this:
-
-------------------------------------------------
-README
-Makefile
-Documentation
-*.h
-*.c
-t

+Crash Reports
+-------------
+If fast-import is supplied invalid input it will terminate with a
+non-zero exit status and create a crash report in the top level of
+the Git repository it was importing into.  Crash reports contain
+a snapshot of the internal fast-import state as well as the most
+recent commands that lead up to the crash.
+
+All recent commands (including stream comments, file changes and
+progress commands) are shown in the command history within the crash
+report, but raw file data and commit messages are excluded from the
+crash report.  This exclusion saves space within the report file
+and reduces the amount of buffering that fast-import must perform
+during execution.
+
+After writing a crash report fast-import will close the current
+packfile and export the marks table.  This allows the frontend
+developer to inspect the repository state and resume the import from
+the point where it crashed.  The modified branches and tags are not
+updated during a crash, as the import did not complete successfully.

+can configure the absolute path to konqueror by setting
+'man.konqueror.path'. Otherwise, 'git-help' assumes the tool is
+available in PATH.
+
+man.<tool>.cmd
+~~~~~~~~~~~~~~
+
+When the man viewer, specified by the 'man.viewer' configuration
+variables, is not among the supported ones, then the corresponding
+'man.<tool>.cmd' configuration variable will be looked up. If this
+variable exists then the specified tool will be treated as a custom
+command and a shell eval will be used to run the command with the man
+page passed as arguments.
+
+Note about konqueror
+~~~~~~~~~~~~~~~~~~~~
+
+When 'konqueror' is specified in the 'man.viewer' configuration
+variable, we launch 'kfmclient' to try to open the man page on an
+already opened konqueror in a new tab if possible.
+
+For consistency, we also try such a trick if 'man.konqueror.path' is
+set to something like 'A_PATH_TO/konqueror'. That means we will try to
+launch 'A_PATH_TO/kfmclient' instead.
+
+If you really want to use 'konqueror', then you can use something like
+the following:
+
+------------------------------------------------
+       [man]
+               viewer = konq
+
+       [man "konq"]

 HOW MERGE WORKS
 ---------------
 
 A merge is always between the current `HEAD` and one or more
-remote branch heads, and the index file must exactly match the
-tree of `HEAD` commit (i.e. the contents of the last commit) when
-it happens.  In other words, `git-diff --cached HEAD` must
-report no changes.
-
-[NOTE]
-This is a bit of a lie.  In certain special cases, your index is
-allowed to be different from the tree of the `HEAD` commit.  The most
-notable case is when your `HEAD` commit is already ahead of what
-is being merged, in which case your index can have arbitrary
-differences from your `HEAD` commit.  Also, your index entries
-may have differences from your `HEAD` commit that match
-the result of a trivial merge (e.g. you received the same patch
-from an external source to produce the same result as what you are
-merging).  For example, if a path did not exist in the common
-ancestor and your head commit but exists in the tree you are
-merging into your repository, and if you already happen to have
-that path exactly in your index, the merge does not have to
-fail.
-
-Otherwise, merge will refuse to do any harm to your repository
-(that is, it may fetch the objects from remote, and it may even
-update the local branch used to keep track of the remote branch
-with `git pull remote rbranch:lbranch`, but your working tree,
-`.git/HEAD` pointer and index file are left intact).
-
-You may have local modifications in the working tree files.  In
-other words, `git-diff` is allowed to report changes.
-However, the merge uses your working tree as the working area,
-and in order to prevent the merge operation from losing such
-changes, it makes sure that they do not interfere with the
-merge. Those complex tables in read-tree documentation define
-what it means for a path to "interfere with the merge".  And if
-your local modifications interfere with the merge, again, it
-stops before touching anything.
-
-So in the above two "failed merge" case, you do not have to
-worry about loss of data --- you simply were not ready to do
-a merge, so no merge happened at all.  You may want to finish
-whatever you were in the middle of doing, and retry the same
-pull after you are done and ready.
-
+commits (usually, branch head or tag), and the index file must
+match the tree of `HEAD` commit (i.e. the contents of the last commit)
+when it starts out.  In other words, `git diff --cached HEAD` must
+report no changes.  (One exception is when the changed index
+entries are already in the same state that would result from
+the merge anyway.)
+
+Three kinds of merge can happen:
+
+* The merged commit is already contained in `HEAD`. This is the
+  simplest case, called "Already up-to-date."
+
+* `HEAD` is already contained in the merged commit. This is the
+  most common case especially when involved through 'git pull':
+  you are tracking an upstream repository, committed no local
+  changes and now you want to update to a newer upstream revision.
+  Your `HEAD` (and the index) is updated to at point the merged
+  commit, without creating an extra merge commit.  This is
+  called "Fast-forward".
+
+* Both the merged commit and `HEAD` are independent and must be
+  tied together by a merge commit that has them both as its parents.
+  The rest of this section describes this "True merge" case.
+
+The chosen merge strategy merges the two commits into a single
+new source tree.

 to merge the retrieved head(s) into the current branch.

+OUTPUT
+------
+
+The output of "git push" depends on the transport method used; this
+section describes the output when pushing over the git protocol (either
+locally or via ssh).
+
+The status of the push is output in tabular form, with each line
+representing the status of a single ref. Each line is of the form:
+
+-------------------------------
+ <flag> <summary> <from> -> <to> (<reason>)
+-------------------------------
+
+flag::
+       A single character indicating the status of the ref. This is
+       blank for a successfully pushed ref, `!` for a ref that was
+       rejected or failed to push, and '=' for a ref that was up to
+       date and did not need pushing (note that the status of up to
+       date refs is shown only when `git push` is running verbosely).
+
+summary::
+       For a successfully pushed ref, the summary shows the old and new
+       values of the ref in a form suitable for using as an argument to
+       `git log` (this is `<old>..<new>` in most cases, and
+       `<old>...<new>` for forced non-fast forward updates). For a
+       failed update, more details are given for the failure.
+       The string `rejected` indicates that git did not try to send the
+       ref at all (typically because it is not a fast forward). The
+       string `remote rejected` indicates that the remote end refused
+       the update; this rejection is typically caused by a hook on the
+       remote side. The string `remote failure` indicates that the
+       remote end did not report the successful update of the ref
+       (perhaps because of a temporary error on the remote side, a
+       break in the network connection, or other transient error).
+
+from::
+       The name of the local ref being pushed, minus its
+       `refs/<type>/` prefix. In the case of deletion, the
+       name of the local ref is omitted.
+
+to::
+       The name of the remote ref being updated, minus its
+       `refs/<type>/` prefix.
+
+reason::
+       A human-readable explanation. In the case of successfully pushed
+       refs, no explanation is needed. For a failed ref, the reason for
+       failure is described.

+The <file> list given to the command can be exact pathnames,
+file glob patterns, or leading directory names.  The command
+removes only the paths that are known to git.  Giving the name of
 a file that you have not told git about does not remove that file.
 
+File globbing matches across directory boundaries.  Thus, given
+two directories `d` and `d2`, there is a difference between
+using `git rm \'d\*\'` and `git rm \'d/\*\'`, as the former will
+also remove all of directory `d2`.
 
 EXAMPLES
 --------
-git-rm Documentation/\\*.txt::
+git rm Documentation/\\*.txt::
        Removes all `\*.txt` files from the index that are under the

+of files and subdirectories under the `Documentation/` directory.
 
-git-rm -f git-*.sh::
-       Remove all git-*.sh scripts that are in the index.
+git rm -f git-*.sh::
        Because this example lets the shell expand the asterisk
        (i.e. you are listing the files explicitly), it
        does not remove `subdir/git-foo.sh`.

+
+DESCRIPTION
+-----------
+Submodules allow foreign repositories to be embedded within
+a dedicated subdirectory of the source tree, always pointed
+at a particular commit.
+
+They are not to be confused with remotes, which are meant mainly
+for branches of the same project; submodules are meant for
+different projects you would like to make part of your source tree,
+while the history of the two projects still stays completely
+independent and you cannot modify the contents of the submodule
+from within the main project.
+If you want to merge the project histories and want to treat the
+aggregated whole as a single project from then on, you may want to
+add a remote for the other project and use the 'subtree' merge strategy,
+instead of treating the other project as a submodule. Directories
+that come from both projects can be cloned and checked out as a whole
+if you choose to go that route.
+
+Submodules are composed from a so-called `gitlink` tree entry
+in the main repository that refers to a particular commit object
+within the inner repository that is completely separate.
+A record in the `.gitmodules` file at the root of the source
+tree assigns a logical name to the submodule and describes
+the default URL the submodule shall be cloned from.
+The logical name can be used for overriding this URL within your
+local repository configuration (see 'submodule init').
+
+This command will manage the tree entries and contents of the
+gitmodules file for you, as well as inspect the status of your
+submodules and update them.
+When adding a new submodule to the tree, the 'add' subcommand
+is to be used.  However, when pulling a tree containing submodules,
+these will not be checked out by default;
+the 'init' and 'update' subcommands will maintain submodules
+checked out and at appropriate revision in your working tree.
+You can briefly inspect the up-to-date status of your submodules
+using the 'status' subcommand and get a detailed overview of the
+difference between the index and checkouts using the 'summary'
+subcommand.
 
 
 COMMANDS
 --------
 add::
        Add the given repository as a submodule at the given path
-       to the changeset to be committed next.  In particular, the
-       repository is cloned at the specified path, added to the
-       changeset and registered in .gitmodules.   If no path is
-       specified, the path is deduced from the repository specification.
-       If the repository url begins with ./ or ../, it is stored as
-       given but resolved as a relative path from the main project's
-       url when cloning.
+       to the changeset to be committed next to the current
+       project: the current project is termed the "superproject".
++
+This requires two arguments: <repository> and <path>.
++
+<repository> is the URL of the new submodule's origin repository.
+This may be either an absolute URL, or (if it begins with ./
+or ../), the location relative to the superproject's origin
+repository.
++
+<path> is the relative location for the cloned submodule to
+exist in the superproject. If <path> does not exist, then the
+submodule is created by cloning from the named URL. If <path> does
+exist and is already a valid git repository, then this is added
+to the changeset without cloning. This second form is provided
+to ease creating a new submodule from scratch, and presumes
+the user will later push the submodule to the given URL.
++
+In either case, the given URL is recorded into .gitmodules for
+use by subsequent users cloning the superproject. If the URL is
+given relative to the superproject's repository, the presumption
+is the superproject and submodule repositories will be kept
+together in the same relative location, and only the
+superproject's URL need be provided: git-submodule will correctly
+locate the submodule using the relative URL in .gitmodules.
 
 status::
        Show the status of the submodules. This will print the SHA-1 of the
        currently checked out commit for each submodule, along with the
-       submodule path and the output of linkgit:git-describe[1] for the
+       submodule path and the output of 'git-describe' for the
        SHA-1. Each SHA-1 will be prefixed with `-` if the submodule is not
        initialized and `+` if the currently checked out submodule commit
        does not match the SHA-1 found in the index of the containing
-       repository. This command is the default command for git-submodule.
+       repository. This command is the default command for 'git-submodule'.
 
 init::
-       Initialize the submodules, i.e. register in .git/config each submodule
-       name and url found in .gitmodules. The key used in .git/config is
-       `submodule.$name.url`. This command does not alter existing information
-       in .git/config.

+       The key used in .git/config is `submodule.$name.url`.
+       This command does not alter existing information in .git/config.
+       You can then customize the submodule clone URLs in .git/config
+       for your local setup and proceed to 'git submodule update';
+       you can also just use 'git submodule update --init' without
+       the explicit 'init' step if you do not intend to customize
+       any submodule locations.
 
 update::
        Update the registered submodules, i.e. clone missing submodules and
        checkout the commit specified in the index of the containing repository.
        This will make the submodules HEAD be detached.
++
+If the submodule is not yet initialized, and you just want to use the
+setting as stored in .gitmodules, you can automatically initialize the
+submodule with the --init option.
 
+summary::
+       Show commit summary between the given commit (defaults to HEAD) and
+       working tree/index. For a submodule in question, a series of commits
+       in the submodule between the given super project commit and the
+       index or working tree (switched by --cached) are shown.

 DESCRIPTION

-git-svn is a simple conduit for changesets between Subversion and git.
-It is not to be confused with linkgit:git-svnimport[1], which is
-read-only.
+'git-svn' is a simple conduit for changesets between Subversion and git.
+It provides a bidirectional flow of changes between a Subversion and a git
+repository.
 
-git-svn was originally designed for an individual developer who wants a
-bidirectional flow of changesets between a single branch in Subversion
-and an arbitrary number of branches in git.  Since its inception,
-git-svn has gained the ability to track multiple branches in a manner
-similar to git-svnimport.
+'git-svn' can track a single Subversion branch simply by using a
+URL to the branch, follow branches laid out in the Subversion recommended
+method (trunk, branches, tags directories) with the --stdlayout option, or
+follow branches in any layout with the -T/-t/-b options (see options to
+'init' below, and also the 'clone' command).
 
-git-svn is especially useful when it comes to tracking repositories
-not organized in the way Subversion developers recommend (trunk,
-branches, tags directories).
+Once tracking a Subversion branch (with any of the above methods), the git
+repository can be updated from Subversion by the 'fetch' command and
+Subversion updated from git by the 'dcommit' command.

+NAME
+----
+git-web--browse - git helper script to launch a web browser
+
+SYNOPSIS
+--------
+'git web--browse' [OPTIONS] URL/FILE ...
+
+DESCRIPTION
+-----------
+
+This script tries, as much as possible, to display the URLs and FILEs
+that are passed as arguments, as HTML pages in new tabs on an already
+opened web browser.
+
+The following browsers (or commands) are currently supported:
+
+* firefox (this is the default under X Window when not using KDE)
+* iceweasel
+* konqueror (this is the default under KDE, see 'Note about konqueror' below)
+* w3m (this is the default outside graphical environments)
+* links
+* lynx
+* dillo
+* open (this is the default under Mac OS X GUI)
+
+Custom commands may also be specified.
+
+OPTIONS
+-------
+-b BROWSER::
+--browser=BROWSER::
+       Use the specified BROWSER. It must be in the list of supported
+       browsers.
+
+-t BROWSER::
+--tool=BROWSER::
+       Same as above.
+
+-c CONF.VAR::
+--config=CONF.VAR::
+       CONF.VAR is looked up in the git config files. If it's set,
+       then its value specify the browser that should be used.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+CONF.VAR (from -c option) and web.browser
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The web browser can be specified using a configuration variable passed
+with the -c (or --config) command line option, or the 'web.browser'
+configuration variable if the former is not used.
+
+browser.<tool>.path
+~~~~~~~~~~~~~~~~~~~
+
+You can explicitly provide a full path to your preferred browser by
+setting the configuration variable 'browser.<tool>.path'. For example,
+you can configure the absolute path to firefox by setting
+'browser.firefox.path'. Otherwise, 'git-web--browse' assumes the tool
+is available in PATH.
+
+browser.<tool>.cmd
+~~~~~~~~~~~~~~~~~~
+
+When the browser, specified by options or configuration variables, is
+not among the supported ones, then the corresponding
+'browser.<tool>.cmd' configuration variable will be looked up. If this
+variable exists then 'git-web--browse' will treat the specified tool
+as a custom command and will use a shell eval to run the command with
+the URLs passed as arguments.
+
+Note about konqueror
+--------------------
+
+When 'konqueror' is specified by the a command line option or a
+configuration variable, we launch 'kfmclient' to try to open the HTML
+man page on an already opened konqueror in a new tab if possible.
+
+For consistency, we also try such a trick if 'browser.konqueror.path' is
+set to something like 'A_PATH_TO/konqueror'. That means we will try to
+launch 'A_PATH_TO/kfmclient' instead.
+
+If you really want to use 'konqueror', then you can use something like
+the following:
+
+------------------------------------------------
+       [web]
+               browser = konq
+
+       [browser "konq"]
+               cmd = A_PATH_TO/konqueror
+------------------------------------------------
+
+Note about git-config --global
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note that these configuration variables should probably be set using
+the '--global' flag, for example like this:
+
+------------------------------------------------
+$ git config --global web.browser firefox
+------------------------------------------------
+
+as they are probably more user specific than repository specific.
+See linkgit:git-config[1] for more information about this.

+Many commands take revisions (most often "commits", but sometimes
+"tree-ish", depending on the context and command) and paths as their
+arguments.  Here are the rules:
+
+ * Revisions come first and then paths.
+   E.g. in `git diff v1.0 v2.0 arch/x86 include/asm-x86`,
+   `v1.0` and `v2.0` are revisions and `arch/x86` and `include/asm-x86`
+   are paths.
+
+ * When an argument can be misunderstood as either a revision or a path,
+   they can be disambiguated by placing `\--` between them.
+   E.g. `git diff \-- HEAD` is, "I have a file called HEAD in my work
+   tree.  Please show changes between the version I staged in the index
+   and what I have in the work tree for that file". not "show difference
+   between the HEAD commit and the work tree as a whole".  You can say
+   `git diff HEAD \--` to ask for the latter.
+
+ * Without disambiguating `\--`, git makes a reasonable guess, but errors
+   out and asking you to disambiguate when ambiguous.  E.g. if you have a
+   file called HEAD in your work tree, `git diff HEAD` is ambiguous, and
+   you have to say either `git diff HEAD \--` or `git diff \-- HEAD` to
+   disambiguate.
+
+When writing a script that is expected to handle random user-input, it is
+a good practice to make it explicit which arguments are which by placing
+disambiguating `\--` at appropriate places.
+
+Here are the rules regarding the "flags" that you should follow when you are

+NOTES ON FREQUENTLY CONFUSED OPTIONS
+------------------------------------
+
+Many commands that can work on files in the working tree
+and/or in the index can take `--cached` and/or `--index`
+options.  Sometimes people incorrectly think that, because
+the index was originally called cache, these two are
+synonyms.  They are *not* -- these two options mean very
+different things.
+
+ * The `--cached` option is used to ask a command that
+   usually works on files in the working tree to *only* work
+   with the index.  For example, `git grep`, when used
+   without a commit to specify from which commit to look for
+   strings in, usually works on files in the working tree,
+   but with the `--cached` option, it looks for strings in
+   the index.
+
+ * The `--index` option is used to ask a command that
+   usually works on files in the working tree to *also*
+   affect the index.  For example, `git stash apply` usually
+   merges changes recorded in a stash to the working tree,
+   but with the `--index` option, it also merges changes to
+   the index as well.
+
+`git apply` command can be used with `--cached` and
+`--index` (but not at the same time).  Usually the command
+only affects the files in the working tree, but with
+`--index`, it patches both the files and their index
+entries, and with `--cached`, it modifies only the index
+entries.

+NAME
+----
+gitcore-tutorial - A git core tutorial for developers
+
+SYNOPSIS
+--------
+git *
+
+DESCRIPTION
+-----------
+
+This tutorial explains how to use the "core" git programs to set up and
+work with a git repository.
+
+If you just need to use git as a revision control system you may prefer
+to start with "A Tutorial Introduction to GIT" (linkgit:gittutorial[7]) or
+link:user-manual.html[the GIT User Manual].
+
+However, an understanding of these low-level tools can be helpful if
+you want to understand git's internals.
+
+The core git is often called "plumbing", with the prettier user
+interfaces on top of it called "porcelain". You may not want to use the
+plumbing directly very often, but it can be good to know what the
+plumbing does for when the porcelain isn't flushing.
+
+[NOTE]
+Deeper technical details are often marked as Notes, which you can
+skip on your first reading.
+
+
+Creating a git repository
+-------------------------
+
+Creating a new git repository couldn't be easier: all git repositories start
+out empty, and the only thing you need to do is find yourself a
+subdirectory that you want to use as a working tree - either an empty
+one for a totally new project, or an existing working tree that you want
+to import into git.
+
+For our first example, we're going to start a totally new repository from
+scratch, with no pre-existing files, and we'll call it 'git-tutorial'.
+To start up, create a subdirectory for it, change into that
+subdirectory, and initialize the git infrastructure with 'git-init':
+
+------------------------------------------------
+$ mkdir git-tutorial
+$ cd git-tutorial
+$ git init
+------------------------------------------------
+
+to which git will reply
+
+----------------
+Initialized empty Git repository in .git/
+----------------
+
+which is just git's way of saying that you haven't been doing anything
+strange, and that it will have created a local `.git` directory setup for
+your new project. You will now have a `.git` directory, and you can
+inspect that with 'ls'. For your new empty project, it should show you
+three entries, among other things:
+
+ - a file called `HEAD`, that has `ref: refs/heads/master` in it.
+   This is similar to a symbolic link and points at
+   `refs/heads/master` relative to the `HEAD` file.
++
+Don't worry about the fact that the file that the `HEAD` link points to
+doesn't even exist yet -- you haven't created the commit that will
+start your `HEAD` development branch yet.
+
+ - a subdirectory called `objects`, which will contain all the
+   objects of your project. You should never have any real reason to
+   look at the objects directly, but you might want to know that these
+   objects are what contains all the real 'data' in your repository.
+
+ - a subdirectory called `refs`, which contains references to objects.
+
+In particular, the `refs` subdirectory will contain two other
+subdirectories, named `heads` and `tags` respectively. They do
+exactly what their names imply: they contain references to any number
+of different 'heads' of development (aka 'branches'), and to any
+'tags' that you have created to name specific versions in your
+repository.
+
+One note: the special `master` head is the default branch, which is
+why the `.git/HEAD` file was created points to it even if it
+doesn't yet exist. Basically, the `HEAD` link is supposed to always
+point to the branch you are working on right now, and you always
+start out expecting to work on the `master` branch.
+
+However, this is only a convention, and you can name your branches
+anything you want, and don't have to ever even 'have' a `master`
+branch. A number of the git tools will assume that `.git/HEAD` is
+valid, though.
+
+[NOTE]
+An 'object' is identified by its 160-bit SHA1 hash, aka 'object name',
+and a reference to an object is always the 40-byte hex
+representation of that SHA1 name. The files in the `refs`
+subdirectory are expected to contain these hex references
+(usually with a final `\'\n\'` at the end), and you should thus
+expect to see a number of 41-byte files containing these
+references in these `refs` subdirectories when you actually start
+populating your tree.
+
+[NOTE]
+An advanced user may want to take a look at linkgit:gitrepository-layout[5]
+after finishing this tutorial.
+
+You have now created your first git repository. Of course, since it's
+empty, that's not very useful, so let's start populating it with data.
+
+
+Populating a git repository
+---------------------------
+
+We'll keep this simple and stupid, so we'll start off with populating a
+few trivial files just to get a feel for it.
+
+Start off with just creating any random files that you want to maintain
+in your git repository. We'll start off with a few bad examples, just to
+get a feel for how this works:
+
+------------------------------------------------
+$ echo "Hello World" >hello
+$ echo "Silly example" >example
+------------------------------------------------
+
+you have now created two files in your working tree (aka 'working directory'),
+but to actually check in your hard work, you will have to go through two steps:
+
+ - fill in the 'index' file (aka 'cache') with the information about your
+   working tree state.
+
+ - commit that index file as an object.
+
+The first step is trivial: when you want to tell git about any changes
+to your working tree, you use the 'git-update-index' program. That
+program normally just takes a list of filenames you want to update, but
+to avoid trivial mistakes, it refuses to add new entries to the index
+(or remove existing ones) unless you explicitly tell it that you're
+adding a new entry with the `\--add` flag (or removing an entry with the
+`\--remove`) flag.
+
+So to populate the index with the two files you just created, you can do
+
+------------------------------------------------
+$ git update-index --add hello example
+------------------------------------------------
+
+and you have now told git to track those two files.
+
+In fact, as you did that, if you now look into your object directory,
+you'll notice that git will have added two new objects to the object
+database. If you did exactly the steps above, you should now be able to do
+
+
+----------------
+$ ls .git/objects/??/*
+----------------
+
+and see two files:
+
+----------------
+.git/objects/55/7db03de997c86a4a028e1ebd3a1ceb225be238
+.git/objects/f2/4c74a2e500f5ee1332c86b94199f52b1d1d962
+----------------
+
+which correspond with the objects with names of `557db...` and
+`f24c7...` respectively.
+
+If you want to, you can use 'git-cat-file' to look at those objects, but
+you'll have to use the object name, not the filename of the object:
+
+----------------
+$ git cat-file -t 557db03de997c86a4a028e1ebd3a1ceb225be238
+----------------
+
+where the `-t` tells 'git-cat-file' to tell you what the "type" of the
+object is. git will tell you that you have a "blob" object (i.e., just a
+regular file), and you can see the contents with
+
+----------------
+$ git cat-file "blob" 557db03
+----------------
+
+which will print out "Hello World". The object `557db03` is nothing
+more than the contents of your file `hello`.
+
+[NOTE]
+Don't confuse that object with the file `hello` itself. The
+object is literally just those specific *contents* of the file, and
+however much you later change the contents in file `hello`, the object
+we just looked at will never change. Objects are immutable.
+
+[NOTE]
+The second example demonstrates that you can
+abbreviate the object name to only the first several
+hexadecimal digits in most places.
+
+Anyway, as we mentioned previously, you normally never actually take a
+look at the objects themselves, and typing long 40-character hex
+names is not something you'd normally want to do. The above digression
+was just to show that 'git-update-index' did something magical, and
+actually saved away the contents of your files into the git object
+database.
+
+Updating the index did something else too: it created a `.git/index`
+file. This is the index that describes your current working tree, and
+something you should be very aware of. Again, you normally never worry
+about the index file itself, but you should be aware of the fact that
+you have not actually really "checked in" your files into git so far,
+you've only *told* git about them.
+
+However, since git knows about them, you can now start using some of the
+most basic git commands to manipulate the files or look at their status.
+
+In particular, let's not even check in the two files into git yet, we'll
+start off by adding another line to `hello` first:
+
+------------------------------------------------
+$ echo "It's a new day for git" >>hello
+------------------------------------------------
+
+and you can now, since you told git about the previous state of `hello`, ask
+git what has changed in the tree compared to your old index, using the
+'git-diff-files' command:
+
+------------
+$ git diff-files
+------------
+
+Oops. That wasn't very readable. It just spit out its own internal
+version of a 'diff', but that internal version really just tells you
+that it has noticed that "hello" has been modified, and that the old object
+contents it had have been replaced with something else.
+
+To make it readable, we can tell 'git-diff-files' to output the
+differences as a patch, using the `-p` flag:
+
+------------
+$ git diff-files -p
+diff --git a/hello b/hello
+index 557db03..263414f 100644
+--- a/hello
++++ b/hello
+@@ -1 +1,2 @@
+ Hello World
++It's a new day for git
+----
+
+i.e. the diff of the change we caused by adding another line to `hello`.
+
+In other words, 'git-diff-files' always shows us the difference between
+what is recorded in the index, and what is currently in the working
+tree. That's very useful.
+
+A common shorthand for `git diff-files -p` is to just write `git
+diff`, which will do the same thing.
+
+------------
+$ git diff
+diff --git a/hello b/hello
+index 557db03..263414f 100644
+--- a/hello
++++ b/hello
+@@ -1 +1,2 @@
+ Hello World
++It's a new day for git
+------------
+
+
+Committing git state
+--------------------
+
+Now, we want to go to the next stage in git, which is to take the files
+that git knows about in the index, and commit them as a real tree. We do
+that in two phases: creating a 'tree' object, and committing that 'tree'
+object as a 'commit' object together with an explanation of what the
+tree was all about, along with information of how we came to that state.
+
+Creating a tree object is trivial, and is done with 'git-write-tree'.
+There are no options or other input: `git write-tree` will take the
+current index state, and write an object that describes that whole
+index. In other words, we're now tying together all the different
+filenames with their contents (and their permissions), and we're
+creating the equivalent of a git "directory" object:
+
+------------------------------------------------
+$ git write-tree
+------------------------------------------------
+
+and this will just output the name of the resulting tree, in this case
+(if you have done exactly as I've described) it should be
+
+----------------
+8988da15d077d4829fc51d8544c097def6644dbb
+----------------
+
+which is another incomprehensible object name. Again, if you want to,
+you can use `git cat-file -t 8988d\...` to see that this time the object
+is not a "blob" object, but a "tree" object (you can also use
+`git cat-file` to actually output the raw object contents, but you'll see
+mainly a binary mess, so that's less interesting).
+
+However -- normally you'd never use 'git-write-tree' on its own, because
+normally you always commit a tree into a commit object using the
+'git-commit-tree' command. In fact, it's easier to not actually use
+'git-write-tree' on its own at all, but to just pass its result in as an
+argument to 'git-commit-tree'.
+
+'git-commit-tree' normally takes several arguments -- it wants to know
+what the 'parent' of a commit was, but since this is the first commit
+ever in this new repository, and it has no parents, we only need to pass in
+the object name of the tree. However, 'git-commit-tree' also wants to get a
+commit message on its standard input, and it will write out the resulting
+object name for the commit to its standard output.
+
+And this is where we create the `.git/refs/heads/master` file
+which is pointed at by `HEAD`. This file is supposed to contain
+the reference to the top-of-tree of the master branch, and since
+that's exactly what 'git-commit-tree' spits out, we can do this
+all with a sequence of simple shell commands:
+
+------------------------------------------------
+$ tree=$(git write-tree)
+$ commit=$(echo 'Initial commit' | git commit-tree $tree)
+$ git update-ref HEAD $commit
+------------------------------------------------
+
+In this case this creates a totally new commit that is not related to
+anything else. Normally you do this only *once* for a project ever, and
+all later commits will be parented on top of an earlier commit.
+
+Again, normally you'd never actually do this by hand. There is a
+helpful script called `git commit` that will do all of this for you. So
+you could have just written `git commit`
+instead, and it would have done the above magic scripting for you.
+
+
+Making a change
+---------------
+
+Remember how we did the 'git-update-index' on file `hello` and then we
+changed `hello` afterward, and could compare the new state of `hello` with the
+state we saved in the index file?
+
+Further, remember how I said that 'git-write-tree' writes the contents
+of the *index* file to the tree, and thus what we just committed was in
+fact the *original* contents of the file `hello`, not the new ones. We did
+that on purpose, to show the difference between the index state, and the
+state in the working tree, and how they don't have to match, even
+when we commit things.
+
+As before, if we do `git diff-files -p` in our git-tutorial project,
+we'll still see the same difference we saw last time: the index file
+hasn't changed by the act of committing anything. However, now that we
+have committed something, we can also learn to use a new command:
+'git-diff-index'.
+
+Unlike 'git-diff-files', which showed the difference between the index
+file and the working tree, 'git-diff-index' shows the differences
+between a committed *tree* and either the index file or the working
+tree. In other words, 'git-diff-index' wants a tree to be diffed
+against, and before we did the commit, we couldn't do that, because we
+didn't have anything to diff against.
+
+But now we can do
+
+----------------
+$ git diff-index -p HEAD
+----------------
+
+(where `-p` has the same meaning as it did in 'git-diff-files'), and it
+will show us the same difference, but for a totally different reason.
+Now we're comparing the working tree not against the index file,
+but against the tree we just wrote. It just so happens that those two
+are obviously the same, so we get the same result.
+
+Again, because this is a common operation, you can also just shorthand
+it with
+
+----------------
+$ git diff HEAD
+----------------
+
+which ends up doing the above for you.
+
+In other words, 'git-diff-index' normally compares a tree against the
+working tree, but when given the `\--cached` flag, it is told to
+instead compare against just the index cache contents, and ignore the
+current working tree state entirely. Since we just wrote the index
+file to HEAD, doing `git diff-index \--cached -p HEAD` should thus return
+an empty set of differences, and that's exactly what it does.
+
+[NOTE]
+================
+'git-diff-index' really always uses the index for its
+comparisons, and saying that it compares a tree against the working
+tree is thus not strictly accurate. In particular, the list of
+files to compare (the "meta-data") *always* comes from the index file,
+regardless of whether the `\--cached` flag is used or not. The `\--cached`
+flag really only determines whether the file *contents* to be compared
+come from the working tree or not.
+
+This is not hard to understand, as soon as you realize that git simply
+never knows (or cares) about files that it is not told about
+explicitly. git will never go *looking* for files to compare, it
+expects you to tell it what the files are, and that's what the index
+is there for.
+================
+
+However, our next step is to commit the *change* we did, and again, to
+understand what's going on, keep in mind the difference between "working
+tree contents", "index file" and "committed tree". We have changes
+in the working tree that we want to commit, and we always have to
+work through the index file, so the first thing we need to do is to
+update the index cache:
+
+------------------------------------------------
+$ git update-index hello
+------------------------------------------------
+
+(note how we didn't need the `\--add` flag this time, since git knew
+about the file already).
+
+Note what happens to the different 'git-diff-\*' versions here. After
+we've updated `hello` in the index, `git diff-files -p` now shows no
+differences, but `git diff-index -p HEAD` still *does* show that the
+current state is different from the state we committed. In fact, now
+'git-diff-index' shows the same difference whether we use the `--cached`
+flag or not, since now the index is coherent with the working tree.
+
+Now, since we've updated `hello` in the index, we can commit the new
+version. We could do it by writing the tree by hand again, and
+committing the tree (this time we'd have to use the `-p HEAD` flag to
+tell commit that the HEAD was the *parent* of the new commit, and that
+this wasn't an initial commit any more), but you've done that once
+already, so let's just use the helpful script this time:
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+which starts an editor for you to write the commit message and tells you
+a bit about what you have done.
+
+Write whatever message you want, and all the lines that start with '#'
+will be pruned out, and the rest will be used as the commit message for
+the change. If you decide you don't want to commit anything after all at
+this point (you can continue to edit things and update the index), you
+can just leave an empty message. Otherwise `git commit` will commit
+the change for you.
+
+You've now made your first real git commit. And if you're interested in
+looking at what `git commit` really does, feel free to investigate:
+it's a few very simple shell scripts to generate the helpful (?) commit
+message headers, and a few one-liners that actually do the
+commit itself ('git-commit').
+
+
+Inspecting Changes
+------------------
+
+While creating changes is useful, it's even more useful if you can tell
+later what changed. The most useful command for this is another of the
+'diff' family, namely 'git-diff-tree'.
+
+'git-diff-tree' can be given two arbitrary trees, and it will tell you the
+differences between them. Perhaps even more commonly, though, you can
+give it just a single commit object, and it will figure out the parent
+of that commit itself, and show the difference directly. Thus, to get
+the same diff that we've already seen several times, we can now do
+
+----------------
+$ git diff-tree -p HEAD
+----------------
+
+(again, `-p` means to show the difference as a human-readable patch),
+and it will show what the last commit (in `HEAD`) actually changed.
+
+[NOTE]
+============
+Here is an ASCII art by Jon Loeliger that illustrates how
+various diff-\* commands compare things.
+
+                      diff-tree
+                       +----+

+                    |  Backing  |

+                      |  |  "cache"  |
+                      |  +-----------+
+                      |    ^
+                      |    |
+                      |    |  diff-files
+                      |    |
+                      V    V
+                    +-----------+
+                    |  Working  |
+                    | Directory |
+                    +-----------+
+============
+
+More interestingly, you can also give 'git-diff-tree' the `--pretty` flag,
+which tells it to also show the commit message and author and date of the
+commit, and you can tell it to show a whole series of diffs.
+Alternatively, you can tell it to be "silent", and not show the diffs at
+all, but just show the actual commit message.
+
+In fact, together with the 'git-rev-list' program (which generates a
+list of revisions), 'git-diff-tree' ends up being a veritable fount of
+changes. A trivial (but very useful) script called 'git-whatchanged' is
+included with git which does exactly this, and shows a log of recent
+activities.
+
+To see the whole history of our pitiful little git-tutorial project, you
+can do
+
+----------------
+$ git log
+----------------
+
+which shows just the log messages, or if we want to see the log together
+with the associated patches use the more complex (and much more
+powerful)
+
+----------------
+$ git whatchanged -p
+----------------
+
+and you will see exactly what has changed in the repository over its
+short history.
+
+[NOTE]
+When using the above two commands, the initial commit will be shown.
+If this is a problem because it is huge, you can hide it by setting
+the log.showroot configuration variable to false. Having this, you
+can still show it for each command just adding the `\--root` option,
+which is a flag for 'git-diff-tree' accepted by both commands.
+
+With that, you should now be having some inkling of what git does, and
+can explore on your own.
+
+[NOTE]
+Most likely, you are not directly using the core
+git Plumbing commands, but using Porcelain such as 'git-add', `git-rm'
+and `git-commit'.
+
+
+Tagging a version
+-----------------
+
+In git, there are two kinds of tags, a "light" one, and an "annotated tag".
+
+A "light" tag is technically nothing more than a branch, except we put
+it in the `.git/refs/tags/` subdirectory instead of calling it a `head`.
+So the simplest form of tag involves nothing more than
+
+------------------------------------------------
+$ git tag my-first-tag
+------------------------------------------------
+
+which just writes the current `HEAD` into the `.git/refs/tags/my-first-tag`
+file, after which point you can then use this symbolic name for that
+particular state. You can, for example, do
+
+----------------
+$ git diff my-first-tag
+----------------
+
+to diff your current state against that tag which at this point will
+obviously be an empty diff, but if you continue to develop and commit
+stuff, you can use your tag as an "anchor-point" to see what has changed
+since you tagged it.
+
+An "annotated tag" is actually a real git object, and contains not only a
+pointer to the state you want to tag, but also a small tag name and
+message, along with optionally a PGP signature that says that yes,
+you really did
+that tag. You create these annotated tags with either the `-a` or
+`-s` flag to 'git-tag':
+
+----------------
+$ git tag -s <tagname>
+----------------
+
+which will sign the current `HEAD` (but you can also give it another
+argument that specifies the thing to tag, i.e., you could have tagged the
+current `mybranch` point by using `git tag <tagname> mybranch`).
+
+You normally only do signed tags for major releases or things
+like that, while the light-weight tags are useful for any marking you
+want to do -- any time you decide that you want to remember a certain
+point, just create a private tag for it, and you have a nice symbolic
+name for the state at that point.
+
+
+Copying repositories
+--------------------
+
+git repositories are normally totally self-sufficient and relocatable.
+Unlike CVS, for example, there is no separate notion of
+"repository" and "working tree". A git repository normally *is* the
+working tree, with the local git information hidden in the `.git`
+subdirectory. There is nothing else. What you see is what you got.
+
+[NOTE]
+You can tell git to split the git internal information from
+the directory that it tracks, but we'll ignore that for now: it's not
+how normal projects work, and it's really only meant for special uses.
+So the mental model of "the git information is always tied directly to
+the working tree that it describes" may not be technically 100%
+accurate, but it's a good model for all normal use.
+
+This has two implications:
+
+ - if you grow bored with the tutorial repository you created (or you've
+   made a mistake and want to start all over), you can just do simple
++
+----------------
+$ rm -rf git-tutorial
+----------------
++
+and it will be gone. There's no external repository, and there's no
+history outside the project you created.
+
+ - if you want to move or duplicate a git repository, you can do so. There
+   is 'git-clone' command, but if all you want to do is just to
+   create a copy of your repository (with all the full history that
+   went along with it), you can do so with a regular
+   `cp -a git-tutorial new-git-tutorial`.
++
+Note that when you've moved or copied a git repository, your git index
+file (which caches various information, notably some of the "stat"
+information for the files involved) will likely need to be refreshed.
+So after you do a `cp -a` to create a new copy, you'll want to do
++
+----------------
+$ git update-index --refresh
+----------------
++
+in the new repository to make sure that the index file is up-to-date.
+
+Note that the second point is true even across machines. You can
+duplicate a remote git repository with *any* regular copy mechanism, be it
+'scp', 'rsync' or 'wget'.
+
+When copying a remote repository, you'll want to at a minimum update the
+index cache when you do this, and especially with other peoples'
+repositories you often want to make sure that the index cache is in some
+known state (you don't know *what* they've done and not yet checked in),
+so usually you'll precede the 'git-update-index' with a
+
+----------------
+$ git read-tree --reset HEAD
+$ git update-index --refresh
+----------------
+
+which will force a total index re-build from the tree pointed to by `HEAD`.
+It resets the index contents to `HEAD`, and then the 'git-update-index'
+makes sure to match up all index entries with the checked-out files.
+If the original repository had uncommitted changes in its
+working tree, `git update-index --refresh` notices them and
+tells you they need to be updated.
+
+The above can also be written as simply
+
+----------------
+$ git reset
+----------------
+
+and in fact a lot of the common git command combinations can be scripted
+with the `git xyz` interfaces.  You can learn things by just looking
+at what the various git scripts do.  For example, `git reset` used to be
+the above two lines implemented in 'git-reset', but some things like
+'git-status' and 'git-commit' are slightly more complex scripts around
+the basic git commands.
+
+Many (most?) public remote repositories will not contain any of
+the checked out files or even an index file, and will *only* contain the
+actual core git files. Such a repository usually doesn't even have the
+`.git` subdirectory, but has all the git files directly in the
+repository.
+
+To create your own local live copy of such a "raw" git repository, you'd
+first create your own subdirectory for the project, and then copy the
+raw repository contents into the `.git` directory. For example, to
+create your own copy of the git repository, you'd do the following
+
+----------------
+$ mkdir my-git
+$ cd my-git
+$ rsync -rL rsync://rsync.kernel.org/pub/scm/git/git.git/ .git
+----------------
+
+followed by
+
+----------------
+$ git read-tree HEAD
+----------------
+
+to populate the index. However, now you have populated the index, and
+you have all the git internal files, but you will notice that you don't
+actually have any of the working tree files to work on. To get
+those, you'd check them out with
+
+----------------
+$ git checkout-index -u -a
+----------------
+
+where the `-u` flag means that you want the checkout to keep the index
+up-to-date (so that you don't have to refresh it afterward), and the
+`-a` flag means "check out all files" (if you have a stale copy or an
+older version of a checked out tree you may also need to add the `-f`
+flag first, to tell 'git-checkout-index' to *force* overwriting of any old
+files).
+
+Again, this can all be simplified with
+
+----------------
+$ git clone rsync://rsync.kernel.org/pub/scm/git/git.git/ my-git
+$ cd my-git
+$ git checkout
+----------------
+
+which will end up doing all of the above for you.
+
+You have now successfully copied somebody else's (mine) remote
+repository, and checked it out.
+
+
+Creating a new branch
+---------------------
+
+Branches in git are really nothing more than pointers into the git
+object database from within the `.git/refs/` subdirectory, and as we
+already discussed, the `HEAD` branch is nothing but a symlink to one of
+these object pointers.
+
+You can at any time create a new branch by just picking an arbitrary
+point in the project history, and just writing the SHA1 name of that
+object into a file under `.git/refs/heads/`. You can use any filename you
+want (and indeed, subdirectories), but the convention is that the
+"normal" branch is called `master`. That's just a convention, though,
+and nothing enforces it.
+
+To show that as an example, let's go back to the git-tutorial repository we
+used earlier, and create a branch in it. You do that by simply just
+saying that you want to check out a new branch:
+
+------------
+$ git checkout -b mybranch
+------------
+
+will create a new branch based at the current `HEAD` position, and switch
+to it.
+
+[NOTE]
+================================================
+If you make the decision to start your new branch at some
+other point in the history than the current `HEAD`, you can do so by
+just telling 'git-checkout' what the base of the checkout would be.
+In other words, if you have an earlier tag or branch, you'd just do
+
+------------
+$ git checkout -b mybranch earlier-commit
+------------
+
+and it would create the new branch `mybranch` at the earlier commit,
+and check out the state at that time.
+================================================
+
+You can always just jump back to your original `master` branch by doing
+
+------------
+$ git checkout master
+------------
+
+(or any other branch-name, for that matter) and if you forget which
+branch you happen to be on, a simple
+
+------------
+$ cat .git/HEAD
+------------
+
+will tell you where it's pointing.  To get the list of branches
+you have, you can say
+
+------------
+$ git branch
+------------
+
+which used to be nothing more than a simple script around `ls .git/refs/heads`.
+There will be an asterisk in front of the branch you are currently on.
+
+Sometimes you may wish to create a new branch _without_ actually
+checking it out and switching to it. If so, just use the command
+
+------------
+$ git branch <branchname> [startingpoint]
+------------
+
+which will simply _create_ the branch, but will not do anything further.
+You can then later -- once you decide that you want to actually develop
+on that branch -- switch to that branch with a regular 'git-checkout'
+with the branchname as the argument.
+
+
+Merging two branches
+--------------------
+
+One of the ideas of having a branch is that you do some (possibly
+experimental) work in it, and eventually merge it back to the main
+branch. So assuming you created the above `mybranch` that started out
+being the same as the original `master` branch, let's make sure we're in
+that branch, and do some work there.
+
+------------------------------------------------
+$ git checkout mybranch
+$ echo "Work, work, work" >>hello
+$ git commit -m "Some work." -i hello
+------------------------------------------------
+
+Here, we just added another line to `hello`, and we used a shorthand for
+doing both `git update-index hello` and `git commit` by just giving the
+filename directly to `git commit`, with an `-i` flag (it tells
+git to 'include' that file in addition to what you have done to
+the index file so far when making the commit).  The `-m` flag is to give the
+commit log message from the command line.
+
+Now, to make it a bit more interesting, let's assume that somebody else
+does some work in the original branch, and simulate that by going back
+to the master branch, and editing the same file differently there:
+
+------------
+$ git checkout master
+------------
+
+Here, take a moment to look at the contents of `hello`, and notice how they
+don't contain the work we just did in `mybranch` -- because that work
+hasn't happened in the `master` branch at all. Then do
+
+------------
+$ echo "Play, play, play" >>hello
+$ echo "Lots of fun" >>example
+$ git commit -m "Some fun." -i hello example
+------------
+
+since the master branch is obviously in a much better mood.
+
+Now, you've got two branches, and you decide that you want to merge the
+work done. Before we do that, let's introduce a cool graphical tool that
+helps you view what's going on:
+
+----------------
+$ gitk --all
+----------------
+
+will show you graphically both of your branches (that's what the `\--all`
+means: normally it will just show you your current `HEAD`) and their
+histories. You can also see exactly how they came to be from a common
+source.
+
+Anyway, let's exit 'gitk' (`^Q` or the File menu), and decide that we want
+to merge the work we did on the `mybranch` branch into the `master`
+branch (which is currently our `HEAD` too). To do that, there's a nice
+script called 'git-merge', which wants to know which branches you want
+to resolve and what the merge is all about:
+
+------------
+$ git merge -m "Merge work in mybranch" mybranch
+------------
+
+where the first argument is going to be used as the commit message if
+the merge can be resolved automatically.
+
+Now, in this case we've intentionally created a situation where the
+merge will need to be fixed up by hand, though, so git will do as much
+of it as it can automatically (which in this case is just merge the `example`
+file, which had no differences in the `mybranch` branch), and say:
+
+----------------
+       Auto-merging hello
+       CONFLICT (content): Merge conflict in hello
+       Automatic merge failed; fix up by hand
+----------------
+
+It tells you that it did an "Automatic merge", which
+failed due to conflicts in `hello`.
+
+Not to worry. It left the (trivial) conflict in `hello` in the same form you
+should already be well used to if you've ever used CVS, so let's just
+open `hello` in our editor (whatever that may be), and fix it up somehow.
+I'd suggest just making it so that `hello` contains all four lines:
+
+------------
+Hello World
+It's a new day for git
+Play, play, play
+Work, work, work
+------------
+
+and once you're happy with your manual merge, just do a
+
+------------
+$ git commit -i hello
+------------
+
+which will very loudly warn you that you're now committing a merge
+(which is correct, so never mind), and you can write a small merge
+message about your adventures in 'git-merge'-land.
+
+After you're done, start up `gitk \--all` to see graphically what the
+history looks like. Notice that `mybranch` still exists, and you can
+switch to it, and continue to work with it if you want to. The
+`mybranch` branch will not contain the merge, but next time you merge it
+from the `master` branch, git will know how you merged it, so you'll not
+have to do _that_ merge again.
+
+Another useful tool, especially if you do not always work in X-Window
+environment, is `git show-branch`.
+
+------------------------------------------------
+$ git show-branch --topo-order --more=1 master mybranch
+* [master] Merge work in mybranch
+ ! [mybranch] Some work.
+--
+-  [master] Merge work in mybranch
+*+ [mybranch] Some work.
+*  [master^] Some fun.
+------------------------------------------------
+
+The first two lines indicate that it is showing the two branches
+and the first line of the commit log message from their
+top-of-the-tree commits, you are currently on `master` branch
+(notice the asterisk `\*` character), and the first column for
+the later output lines is used to show commits contained in the
+`master` branch, and the second column for the `mybranch`
+branch. Three commits are shown along with their log messages.
+All of them have non blank characters in the first column (`*`
+shows an ordinary commit on the current branch, `-` is a merge commit), which
+means they are now part of the `master` branch. Only the "Some
+work" commit has the plus `+` character in the second column,
+because `mybranch` has not been merged to incorporate these
+commits from the master branch.  The string inside brackets
+before the commit log message is a short name you can use to
+name the commit.  In the above example, 'master' and 'mybranch'
+are branch heads.  'master^' is the first parent of 'master'
+branch head.  Please see linkgit:git-rev-parse[1] if you want to
+see more complex cases.
+
+[NOTE]
+Without the '--more=1' option, 'git-show-branch' would not output the
+'[master^]' commit, as '[mybranch]' commit is a common ancestor of
+both 'master' and 'mybranch' tips.  Please see linkgit:git-show-branch[1]
+for details.
+
+[NOTE]
+If there were more commits on the 'master' branch after the merge, the
+merge commit itself would not be shown by 'git-show-branch' by
+default.  You would need to provide '--sparse' option to make the
+merge commit visible in this case.
+
+Now, let's pretend you are the one who did all the work in
+`mybranch`, and the fruit of your hard work has finally been merged
+to the `master` branch. Let's go back to `mybranch`, and run
+'git-merge' to get the "upstream changes" back to your branch.
+
+------------
+$ git checkout mybranch
+$ git merge -m "Merge upstream changes." master
+------------
+
+This outputs something like this (the actual commit object names
+would be different)
+
+----------------
+Updating from ae3a2da... to a80b4aa....
+Fast forward
+ example |    1 +
+ hello   |    1 +
+ 2 files changed, 2 insertions(+), 0 deletions(-)
+----------------
+
+Because your branch did not contain anything more than what are
+already merged into the `master` branch, the merge operation did
+not actually do a merge. Instead, it just updated the top of
+the tree of your branch to that of the `master` branch. This is
+often called 'fast forward' merge.
+
+You can run `gitk \--all` again to see how the commit ancestry
+looks like, or run 'show-branch', which tells you this.
+
+------------------------------------------------
+$ git show-branch master mybranch
+! [master] Merge work in mybranch
+ * [mybranch] Merge work in mybranch
+--
+-- [master] Merge work in mybranch
+------------------------------------------------
+
+
+Merging external work
+---------------------
+
+It's usually much more common that you merge with somebody else than
+merging with your own branches, so it's worth pointing out that git
+makes that very easy too, and in fact, it's not that different from
+doing a 'git-merge'. In fact, a remote merge ends up being nothing
+more than "fetch the work from a remote repository into a temporary tag"
+followed by a 'git-merge'.
+
+Fetching from a remote repository is done by, unsurprisingly,
+'git-fetch':
+
+----------------
+$ git fetch <remote-repository>
+----------------
+
+One of the following transports can be used to name the
+repository to download from:
+
+Rsync::
+       `rsync://remote.machine/path/to/repo.git/`
++
+Rsync transport is usable for both uploading and downloading,
+but is completely unaware of what git does, and can produce
+unexpected results when you download from the public repository
+while the repository owner is uploading into it via `rsync`
+transport.  Most notably, it could update the files under
+`refs/` which holds the object name of the topmost commits
+before uploading the files in `objects/` -- the downloader would
+obtain head commit object name while that object itself is still
+not available in the repository.  For this reason, it is
+considered deprecated.
+
+SSH::
+       `remote.machine:/path/to/repo.git/` or
++
+`ssh://remote.machine/path/to/repo.git/`
++
+This transport can be used for both uploading and downloading,
+and requires you to have a log-in privilege over `ssh` to the
+remote machine.  It finds out the set of objects the other side
+lacks by exchanging the head commits both ends have and
+transfers (close to) minimum set of objects.  It is by far the
+most efficient way to exchange git objects between repositories.
+
+Local directory::
+       `/path/to/repo.git/`
++
+This transport is the same as SSH transport but uses 'sh' to run
+both ends on the local machine instead of running other end on
+the remote machine via 'ssh'.
+
+git Native::
+       `git://remote.machine/path/to/repo.git/`
++
+This transport was designed for anonymous downloading.  Like SSH
+transport, it finds out the set of objects the downstream side
+lacks and transfers (close to) minimum set of objects.
+
+HTTP(S)::
+       `http://remote.machine/path/to/repo.git/`
++
+Downloader from http and https URL
+first obtains the topmost commit object name from the remote site
+by looking at the specified refname under `repo.git/refs/` directory,
+and then tries to obtain the
+commit object by downloading from `repo.git/objects/xx/xxx\...`
+using the object name of that commit object.  Then it reads the
+commit object to find out its parent commits and the associate
+tree object; it repeats this process until it gets all the
+necessary objects.  Because of this behavior, they are
+sometimes also called 'commit walkers'.
++
+The 'commit walkers' are sometimes also called 'dumb
+transports', because they do not require any git aware smart
+server like git Native transport does.  Any stock HTTP server
+that does not even support directory index would suffice.  But
+you must prepare your repository with 'git-update-server-info'
+to help dumb transport downloaders.
+
+Once you fetch from the remote repository, you `merge` that
+with your current branch.
+
+However -- it's such a common thing to `fetch` and then
+immediately `merge`, that it's called `git pull`, and you can
+simply do
+
+----------------
+$ git pull <remote-repository>
+----------------
+
+and optionally give a branch-name for the remote end as a second
+argument.
+
+[NOTE]
+You could do without using any branches at all, by
+keeping as many local repositories as you would like to have
+branches, and merging between them with 'git-pull', just like
+you merge between branches. The advantage of this approach is
+that it lets you keep a set of files for each `branch` checked
+out and you may find it easier to switch back and forth if you
+juggle multiple lines of development simultaneously. Of
+course, you will pay the price of more disk usage to hold
+multiple working trees, but disk space is cheap these days.
+
+It is likely that you will be pulling from the same remote
+repository from time to time. As a short hand, you can store
+the remote repository URL in the local repository's config file
+like this:
+
+------------------------------------------------
+$ git config remote.linus.url http://www.kernel.org/pub/scm/git/git.git/
+------------------------------------------------
+
+and use the "linus" keyword with 'git-pull' instead of the full URL.
+
+Examples.
+
+. `git pull linus`
+. `git pull linus tag v0.99.1`
+
+the above are equivalent to:
+
+. `git pull http://www.kernel.org/pub/scm/git/git.git/ HEAD`
+. `git pull http://www.kernel.org/pub/scm/git/git.git/ tag v0.99.1`
+
+
+How does the merge work?
+------------------------
+
+We said this tutorial shows what plumbing does to help you cope
+with the porcelain that isn't flushing, but we so far did not
+talk about how the merge really works.  If you are following
+this tutorial the first time, I'd suggest to skip to "Publishing
+your work" section and come back here later.
+
+OK, still with me?  To give us an example to look at, let's go
+back to the earlier repository with "hello" and "example" file,
+and bring ourselves back to the pre-merge state:
+
+------------
+$ git show-branch --more=2 master mybranch
+! [master] Merge work in mybranch
+ * [mybranch] Merge work in mybranch
+--
+-- [master] Merge work in mybranch
++* [master^2] Some work.
++* [master^] Some fun.
+------------
+
+Remember, before running 'git-merge', our `master` head was at
+"Some fun." commit, while our `mybranch` head was at "Some
+work." commit.
+
+------------
+$ git checkout mybranch
+$ git reset --hard master^2
+$ git checkout master
+$ git reset --hard master^
+------------
+
+After rewinding, the commit structure should look like this:
+
+------------
+$ git show-branch
+* [master] Some fun.
+ ! [mybranch] Some work.
+--
+ + [mybranch] Some work.
+*  [master] Some fun.
+*+ [mybranch^] New day.
+------------
+
+Now we are ready to experiment with the merge by hand.
+
+`git merge` command, when merging two branches, uses 3-way merge
+algorithm.  First, it finds the common ancestor between them.
+The command it uses is 'git-merge-base':
+
+------------
+$ mb=$(git merge-base HEAD mybranch)
+------------
+
+The command writes the commit object name of the common ancestor
+to the standard output, so we captured its output to a variable,
+because we will be using it in the next step.  By the way, the common
+ancestor commit is the "New day." commit in this case.  You can
+tell it by:
+
+------------
+$ git name-rev $mb
+my-first-tag
+------------
+
+After finding out a common ancestor commit, the second step is
+this:
+
+------------
+$ git read-tree -m -u $mb HEAD mybranch
+------------
+
+This is the same 'git-read-tree' command we have already seen,
+but it takes three trees, unlike previous examples.  This reads
+the contents of each tree into different 'stage' in the index
+file (the first tree goes to stage 1, the second to stage 2,
+etc.).  After reading three trees into three stages, the paths
+that are the same in all three stages are 'collapsed' into stage
+0.  Also paths that are the same in two of three stages are
+collapsed into stage 0, taking the SHA1 from either stage 2 or
+stage 3, whichever is different from stage 1 (i.e. only one side
+changed from the common ancestor).
+
+After 'collapsing' operation, paths that are different in three
+trees are left in non-zero stages.  At this point, you can
+inspect the index file with this command:
+
+------------
+$ git ls-files --stage
+100644 7f8b141b65fdcee47321e399a2598a235a032422 0      example
+100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1      hello
+100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2      hello
+100644 cc44c73eb783565da5831b4d820c962954019b69 3      hello
+------------
+
+In our example of only two files, we did not have unchanged
+files so only 'example' resulted in collapsing, but in real-life
+large projects, only small number of files change in one commit,
+and this 'collapsing' tends to trivially merge most of the paths
+fairly quickly, leaving only a handful the real changes in non-zero
+stages.
+
+To look at only non-zero stages, use `\--unmerged` flag:
+
+------------
+$ git ls-files --unmerged
+100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1      hello
+100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2      hello
+100644 cc44c73eb783565da5831b4d820c962954019b69 3      hello
+------------
+
+The next step of merging is to merge these three versions of the
+file, using 3-way merge.  This is done by giving
+'git-merge-one-file' command as one of the arguments to
+'git-merge-index' command:
+
+------------
+$ git merge-index git-merge-one-file hello
+Auto-merging hello.
+merge: warning: conflicts during merge
+ERROR: Merge conflict in hello.
+fatal: merge program failed
+------------
+
+'git-merge-one-file' script is called with parameters to
+describe those three versions, and is responsible to leave the
+merge results in the working tree.
+It is a fairly straightforward shell script, and
+eventually calls 'merge' program from RCS suite to perform a
+file-level 3-way merge.  In this case, 'merge' detects
+conflicts, and the merge result with conflict marks is left in
+the working tree..  This can be seen if you run `ls-files
+--stage` again at this point:
+
+------------
+$ git ls-files --stage
+100644 7f8b141b65fdcee47321e399a2598a235a032422 0      example
+100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1      hello
+100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2      hello
+100644 cc44c73eb783565da5831b4d820c962954019b69 3      hello
+------------
+
+This is the state of the index file and the working file after
+'git-merge' returns control back to you, leaving the conflicting
+merge for you to resolve.  Notice that the path `hello` is still
+unmerged, and what you see with 'git-diff' at this point is
+differences since stage 2 (i.e. your version).
+
+
+Publishing your work
+--------------------
+
+So, we can use somebody else's work from a remote repository, but
+how can *you* prepare a repository to let other people pull from
+it?
+
+You do your real work in your working tree that has your
+primary repository hanging under it as its `.git` subdirectory.
+You *could* make that repository accessible remotely and ask
+people to pull from it, but in practice that is not the way
+things are usually done. A recommended way is to have a public
+repository, make it reachable by other people, and when the
+changes you made in your primary working tree are in good shape,
+update the public repository from it. This is often called
+'pushing'.
+
+[NOTE]
+This public repository could further be mirrored, and that is
+how git repositories at `kernel.org` are managed.
+
+Publishing the changes from your local (private) repository to
+your remote (public) repository requires a write privilege on
+the remote machine. You need to have an SSH account there to
+run a single command, 'git-receive-pack'.
+
+First, you need to create an empty repository on the remote
+machine that will house your public repository. This empty
+repository will be populated and be kept up-to-date by pushing
+into it later. Obviously, this repository creation needs to be
+done only once.
+
+[NOTE]
+'git-push' uses a pair of programs,
+'git-send-pack' on your local machine, and 'git-receive-pack'
+on the remote machine. The communication between the two over
+the network internally uses an SSH connection.
+
+Your private repository's git directory is usually `.git`, but
+your public repository is often named after the project name,
+i.e. `<project>.git`. Let's create such a public repository for
+project `my-git`. After logging into the remote machine, create
+an empty directory:
+
+------------
+$ mkdir my-git.git
+------------
+
+Then, make that directory into a git repository by running
+'git-init', but this time, since its name is not the usual
+`.git`, we do things slightly differently:
+
+------------
+$ GIT_DIR=my-git.git git init
+------------
+
+Make sure this directory is available for others you want your
+changes to be pulled by via the transport of your choice. Also
+you need to make sure that you have the 'git-receive-pack'
+program on the `$PATH`.
+
+[NOTE]
+Many installations of sshd do not invoke your shell as the login
+shell when you directly run programs; what this means is that if
+your login shell is 'bash', only `.bashrc` is read and not
+`.bash_profile`. As a workaround, make sure `.bashrc` sets up
+`$PATH` so that you can run 'git-receive-pack' program.
+
+[NOTE]
+If you plan to publish this repository to be accessed over http,
+you should do `mv my-git.git/hooks/post-update.sample
+my-git.git/hooks/post-update` at this point.
+This makes sure that every time you push into this
+repository, `git update-server-info` is run.
+
+Your "public repository" is now ready to accept your changes.
+Come back to the machine you have your private repository. From
+there, run this command:
+
+------------
+$ git push <public-host>:/path/to/my-git.git master
+------------
+
+This synchronizes your public repository to match the named
+branch head (i.e. `master` in this case) and objects reachable
+from them in your current repository.
+
+As a real example, this is how I update my public git
+repository. Kernel.org mirror network takes care of the
+propagation to other publicly visible machines:
+
+------------
+$ git push master.kernel.org:/pub/scm/git/git.git/
+------------
+
+
+Packing your repository
+-----------------------
+
+Earlier, we saw that one file under `.git/objects/??/` directory
+is stored for each git object you create. This representation
+is efficient to create atomically and safely, but
+not so convenient to transport over the network. Since git objects are
+immutable once they are created, there is a way to optimize the
+storage by "packing them together". The command
+
+------------
+$ git repack
+------------
+
+will do it for you. If you followed the tutorial examples, you
+would have accumulated about 17 objects in `.git/objects/??/`
+directories by now. 'git-repack' tells you how many objects it
+packed, and stores the packed file in `.git/objects/pack`
+directory.
+
+[NOTE]
+You will see two files, `pack-\*.pack` and `pack-\*.idx`,
+in `.git/objects/pack` directory. They are closely related to
+each other, and if you ever copy them by hand to a different
+repository for whatever reason, you should make sure you copy
+them together. The former holds all the data from the objects
+in the pack, and the latter holds the index for random
+access.
+
+If you are paranoid, running 'git-verify-pack' command would
+detect if you have a corrupt pack, but do not worry too much.
+Our programs are always perfect ;-).
+
+Once you have packed objects, you do not need to leave the
+unpacked objects that are contained in the pack file anymore.
+
+------------
+$ git prune-packed
+------------
+
+would remove them for you.
+
+You can try running `find .git/objects -type f` before and after
+you run `git prune-packed` if you are curious.  Also `git
+count-objects` would tell you how many unpacked objects are in
+your repository and how much space they are consuming.
+
+[NOTE]
+`git pull` is slightly cumbersome for HTTP transport, as a
+packed repository may contain relatively few objects in a
+relatively large pack. If you expect many HTTP pulls from your
+public repository you might want to repack & prune often, or
+never.
+
+If you run `git repack` again at this point, it will say
+"Nothing to pack". Once you continue your development and
+accumulate the changes, running `git repack` again will create a
+new pack, that contains objects created since you packed your
+repository the last time. We recommend that you pack your project
+soon after the initial import (unless you are starting your
+project from scratch), and then run `git repack` every once in a
+while, depending on how active your project is.
+
+When a repository is synchronized via `git push` and `git pull`
+objects packed in the source repository are usually stored
+unpacked in the destination, unless rsync transport is used.
+While this allows you to use different packing strategies on
+both ends, it also means you may need to repack both
+repositories every once in a while.
+
+
+Working with Others
+-------------------
+
+Although git is a truly distributed system, it is often
+convenient to organize your project with an informal hierarchy
+of developers. Linux kernel development is run this way. There
+is a nice illustration (page 17, "Merges to Mainline") in
+link:http://www.xenotime.net/linux/mentor/linux-mentoring-2006.pdf[Randy Dunlap's presentation].
+
+It should be stressed that this hierarchy is purely *informal*.
+There is nothing fundamental in git that enforces the "chain of
+patch flow" this hierarchy implies. You do not have to pull
+from only one remote repository.
+
+A recommended workflow for a "project lead" goes like this:
+
+1. Prepare your primary repository on your local machine. Your
+   work is done there.
+
+2. Prepare a public repository accessible to others.
++
+If other people are pulling from your repository over dumb
+transport protocols (HTTP), you need to keep this repository
+'dumb transport friendly'.  After `git init`,
+`$GIT_DIR/hooks/post-update.sample` copied from the standard templates
+would contain a call to 'git-update-server-info'
+but you need to manually enable the hook with
+`mv post-update.sample post-update`.  This makes sure
+'git-update-server-info' keeps the necessary files up-to-date.
+
+3. Push into the public repository from your primary
+   repository.
+
+4. 'git-repack' the public repository. This establishes a big
+   pack that contains the initial set of objects as the
+   baseline, and possibly 'git-prune' if the transport
+   used for pulling from your repository supports packed
+   repositories.
+
+5. Keep working in your primary repository. Your changes
+   include modifications of your own, patches you receive via
+   e-mails, and merges resulting from pulling the "public"
+   repositories of your "subsystem maintainers".
++
+You can repack this private repository whenever you feel like.
+
+6. Push your changes to the public repository, and announce it
+   to the public.
+
+7. Every once in a while, "git-repack" the public repository.
+   Go back to step 5. and continue working.
+
+
+A recommended work cycle for a "subsystem maintainer" who works
+on that project and has an own "public repository" goes like this:
+
+1. Prepare your work repository, by 'git-clone' the public
+   repository of the "project lead". The URL used for the
+   initial cloning is stored in the remote.origin.url
+   configuration variable.
+
+2. Prepare a public repository accessible to others, just like
+   the "project lead" person does.
+
+3. Copy over the packed files from "project lead" public
+   repository to your public repository, unless the "project
+   lead" repository lives on the same machine as yours.  In the
+   latter case, you can use `objects/info/alternates` file to
+   point at the repository you are borrowing from.
+
+4. Push into the public repository from your primary
+   repository. Run 'git-repack', and possibly 'git-prune' if the
+   transport used for pulling from your repository supports
+   packed repositories.
+
+5. Keep working in your primary repository. Your changes
+   include modifications of your own, patches you receive via
+   e-mails, and merges resulting from pulling the "public"
+   repositories of your "project lead" and possibly your
+   "sub-subsystem maintainers".
++
+You can repack this private repository whenever you feel
+like.
+
+6. Push your changes to your public repository, and ask your
+   "project lead" and possibly your "sub-subsystem
+   maintainers" to pull from it.
+
+7. Every once in a while, 'git-repack' the public repository.
+   Go back to step 5. and continue working.
+
+
+A recommended work cycle for an "individual developer" who does
+not have a "public" repository is somewhat different. It goes
+like this:
+
+1. Prepare your work repository, by 'git-clone' the public
+   repository of the "project lead" (or a "subsystem
+   maintainer", if you work on a subsystem). The URL used for
+   the initial cloning is stored in the remote.origin.url
+   configuration variable.
+
+2. Do your work in your repository on 'master' branch.
+
+3. Run `git fetch origin` from the public repository of your
+   upstream every once in a while. This does only the first
+   half of `git pull` but does not merge. The head of the
+   public repository is stored in `.git/refs/remotes/origin/master`.
+
+4. Use `git cherry origin` to see which ones of your patches
+   were accepted, and/or use `git rebase origin` to port your
+   unmerged changes forward to the updated upstream.
+
+5. Use `git format-patch origin` to prepare patches for e-mail
+   submission to your upstream and send it out. Go back to
+   step 2. and continue.
+
+
+Working with Others, Shared Repository Style
+--------------------------------------------
+
+If you are coming from CVS background, the style of cooperation
+suggested in the previous section may be new to you. You do not
+have to worry. git supports "shared public repository" style of
+cooperation you are probably more familiar with as well.
+
+See linkgit:gitcvs-migration[7] for the details.
+
+Bundling your work together
+---------------------------
+
+It is likely that you will be working on more than one thing at
+a time.  It is easy to manage those more-or-less independent tasks
+using branches with git.
+
+We have already seen how branches work previously,
+with "fun and work" example using two branches.  The idea is the
+same if there are more than two branches.  Let's say you started
+out from "master" head, and have some new code in the "master"
+branch, and two independent fixes in the "commit-fix" and
+"diff-fix" branches:
+
+------------
+$ git show-branch
+! [commit-fix] Fix commit message normalization.
+ ! [diff-fix] Fix rename detection.
+  * [master] Release candidate #1
+---
+ +  [diff-fix] Fix rename detection.
+ +  [diff-fix~1] Better common substring algorithm.
++   [commit-fix] Fix commit message normalization.
+  * [master] Release candidate #1
+++* [diff-fix~2] Pretty-print messages.
+------------
+
+Both fixes are tested well, and at this point, you want to merge
+in both of them.  You could merge in 'diff-fix' first and then
+'commit-fix' next, like this:
+
+------------
+$ git merge -m "Merge fix in diff-fix" diff-fix
+$ git merge -m "Merge fix in commit-fix" commit-fix
+------------
+
+Which would result in:
+
+------------
+$ git show-branch
+! [commit-fix] Fix commit message normalization.
+ ! [diff-fix] Fix rename detection.
+  * [master] Merge fix in commit-fix
+---
+  - [master] Merge fix in commit-fix
++ * [commit-fix] Fix commit message normalization.
+  - [master~1] Merge fix in diff-fix
+ +* [diff-fix] Fix rename detection.
+ +* [diff-fix~1] Better common substring algorithm.
+  * [master~2] Release candidate #1
+++* [master~3] Pretty-print messages.
+------------
+
+However, there is no particular reason to merge in one branch
+first and the other next, when what you have are a set of truly
+independent changes (if the order mattered, then they are not
+independent by definition).  You could instead merge those two
+branches into the current branch at once.  First let's undo what
+we just did and start over.  We would want to get the master
+branch before these two merges by resetting it to 'master~2':
+
+------------
+$ git reset --hard master~2
+------------
+
+You can make sure `git show-branch` matches the state before
+those two 'git-merge' you just did.  Then, instead of running
+two 'git-merge' commands in a row, you would merge these two
+branch heads (this is known as 'making an Octopus'):
+
+------------
+$ git merge commit-fix diff-fix
+$ git show-branch
+! [commit-fix] Fix commit message normalization.
+ ! [diff-fix] Fix rename detection.
+  * [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
+---
+  - [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
++ * [commit-fix] Fix commit message normalization.
+ +* [diff-fix] Fix rename detection.
+ +* [diff-fix~1] Better common substring algorithm.
+  * [master~1] Release candidate #1
+++* [master~2] Pretty-print messages.
+------------
+
+Note that you should not do Octopus because you can.  An octopus
+is a valid thing to do and often makes it easier to view the
+commit history if you are merging more than two independent
+changes at the same time.  However, if you have merge conflicts
+with any of the branches you are merging in and need to hand
+resolve, that is an indication that the development happened in
+those branches were not independent after all, and you should
+merge two at a time, documenting how you resolved the conflicts,
+and the reason why you preferred changes made in one side over
+the other.  Otherwise it would make the project history harder
+to follow, not easier.

+gitcvs-migration(7)
+===================
+
+NAME
+----
+gitcvs-migration - git for CVS users
+
+SYNOPSIS
+--------
+git cvsimport *
+
+DESCRIPTION
+-----------
+
+Git differs from CVS in that every working tree contains a repository with
+a full copy of the project history, and no repository is inherently more
+important than any other.  However, you can emulate the CVS model by
+designating a single shared repository which people can synchronize with;
+this document explains how to do that.
+
+Some basic familiarity with git is required. Having gone through
+linkgit:gittutorial[7] and
+linkgit:gitglossary[7] should be sufficient.
+
+Developing against a shared repository
+--------------------------------------
+
+Suppose a shared repository is set up in /pub/repo.git on the host
+foo.com.  Then as an individual committer you can clone the shared
+repository over ssh with:
+
+------------------------------------------------
+$ git clone foo.com:/pub/repo.git/ my-project
+$ cd my-project
+------------------------------------------------
+
+and hack away.  The equivalent of 'cvs update' is
+
+------------------------------------------------
+$ git pull origin
+------------------------------------------------
+
+which merges in any work that others might have done since the clone
+operation.  If there are uncommitted changes in your working tree, commit
+them first before running git pull.
+
+[NOTE]
+================================
+The 'pull' command knows where to get updates from because of certain
+configuration variables that were set by the first 'git-clone'
+command; see `git config -l` and the linkgit:git-config[1] man
+page for details.
+================================
+
+You can update the shared repository with your changes by first committing
+your changes, and then using the 'git-push' command:
+
+------------------------------------------------
+$ git push origin master
+------------------------------------------------
+
+to "push" those commits to the shared repository.  If someone else has
+updated the repository more recently, 'git-push', like 'cvs commit', will
+complain, in which case you must pull any changes before attempting the
+push again.
+
+In the 'git-push' command above we specify the name of the remote branch
+to update (`master`).  If we leave that out, 'git-push' tries to update
+any branches in the remote repository that have the same name as a branch
+in the local repository.  So the last 'push' can be done with either of:
+
+------------
+$ git push origin
+$ git push foo.com:/pub/project.git/
+------------
+
+as long as the shared repository does not have any branches
+other than `master`.
+
+Setting Up a Shared Repository
+------------------------------
+
+We assume you have already created a git repository for your project,
+possibly created from scratch or from a tarball (see
+linkgit:gittutorial[7]), or imported from an already existing CVS
+repository (see the next section).
+
+Assume your existing repo is at /home/alice/myproject.  Create a new "bare"
+repository (a repository without a working tree) and fetch your project into
+it:
+
+------------------------------------------------
+$ mkdir /pub/my-repo.git
+$ cd /pub/my-repo.git
+$ git --bare init --shared
+$ git --bare fetch /home/alice/myproject master:master
+------------------------------------------------
+
+Next, give every team member read/write access to this repository.  One
+easy way to do this is to give all the team members ssh access to the
+machine where the repository is hosted.  If you don't want to give them a
+full shell on the machine, there is a restricted shell which only allows
+users to do git pushes and pulls; see linkgit:git-shell[1].
+
+Put all the committers in the same group, and make the repository
+writable by that group:
+
+------------------------------------------------
+$ chgrp -R $group /pub/my-repo.git
+------------------------------------------------
+
+Make sure committers have a umask of at most 027, so that the directories
+they create are writable and searchable by other group members.
+
+Importing a CVS archive
+-----------------------
+
+First, install version 2.1 or higher of cvsps from
+link:http://www.cobite.com/cvsps/[http://www.cobite.com/cvsps/] and make
+sure it is in your path.  Then cd to a checked out CVS working directory
+of the project you are interested in and run 'git-cvsimport':
+
+-------------------------------------------
+$ git cvsimport -C <destination> <module>
+-------------------------------------------
+
+This puts a git archive of the named CVS module in the directory
+<destination>, which will be created if necessary.
+
+The import checks out from CVS every revision of every file.  Reportedly
+cvsimport can average some twenty revisions per second, so for a
+medium-sized project this should not take more than a couple of minutes.
+Larger projects or remote repositories may take longer.
+
+The main trunk is stored in the git branch named `origin`, and additional
+CVS branches are stored in git branches with the same names.  The most
+recent version of the main trunk is also left checked out on the `master`
+branch, so you can start adding your own changes right away.
+
+The import is incremental, so if you call it again next month it will
+fetch any CVS updates that have been made in the meantime.  For this to
+work, you must not modify the imported branches; instead, create new
+branches for your own changes, and merge in the imported branches as
+necessary.
+
+If you want a shared repository, you will need to make a bare clone
+of the imported directory, as described above. Then treat the imported
+directory as another development clone for purposes of merging
+incremental imports.
+
+Advanced Shared Repository Management
+-------------------------------------
+
+Git allows you to specify scripts called "hooks" to be run at certain
+points.  You can use these, for example, to send all commits to the shared
+repository to a mailing list.  See linkgit:githooks[5].
+
+You can enforce finer grained permissions using update hooks.  See
+link:howto/update-hook-example.txt[Controlling access to branches using
+update hooks].
+
+Providing CVS Access to a git Repository
+----------------------------------------
+
+It is also possible to provide true CVS access to a git repository, so
+that developers can still use CVS; see linkgit:git-cvsserver[1] for
+details.
+
+Alternative Development Models
+------------------------------
+
+CVS users are accustomed to giving a group of developers commit access to
+a common repository.  As we've seen, this is also possible with git.
+However, the distributed nature of git allows other development models,
+and you may want to first consider whether one of them might be a better
+fit for your project.
+
+For example, you can choose a single person to maintain the project's
+primary public repository.  Other developers then clone this repository
+and each work in their own clone.  When they have a series of changes that
+they're happy with, they ask the maintainer to pull from the branch
+containing the changes.  The maintainer reviews their changes and pulls
+them into the primary repository, which other developers pull from as
+necessary to stay coordinated.  The Linux kernel and other projects use
+variants of this model.
+
+With a small group, developers may just pull changes from each other's
+repositories without the need for a central maintainer.

+gitdiffcore(7)
+==============
+
+NAME
+----
+gitdiffcore - Tweaking diff output (June 2005)
+
+SYNOPSIS
+--------
+'git diff' *
+
+DESCRIPTION
+-----------
+
+The diff commands 'git-diff-index', 'git-diff-files', and 'git-diff-tree'
+can be told to manipulate differences they find in
+unconventional ways before showing 'diff' output.  The manipulation
+is collectively called "diffcore transformation".  This short note
+describes what they are and how to use them to produce 'diff' output
+that is easier to understand than the conventional kind.
+
+
+The chain of operation
+----------------------
+
+The 'git-diff-{asterisk}' family works by first comparing two sets of
+files:
+
+ - 'git-diff-index' compares contents of a "tree" object and the
+   working directory (when '\--cached' flag is not used) or a
+   "tree" object and the index file (when '\--cached' flag is
+   used);
+
+ - 'git-diff-files' compares contents of the index file and the
+   working directory;
+
+ - 'git-diff-tree' compares contents of two "tree" objects;
+
+In all of these cases, the commands themselves compare
+corresponding paths in the two sets of files.  The result of
+comparison is passed from these commands to what is internally
+called "diffcore", in a format similar to what is output when
+the -p option is not used.  E.g.
+
+------------------------------------------------
+in-place edit  :100644 100644 bcd1234... 0123456... M file0
+create         :000000 100644 0000000... 1234567... A file4
+delete         :100644 000000 1234567... 0000000... D file5
+unmerged       :000000 000000 0000000... 0000000... U file6
+------------------------------------------------
+
+The diffcore mechanism is fed a list of such comparison results
+(each of which is called "filepair", although at this point each
+of them talks about a single file), and transforms such a list
+into another list.  There are currently 6 such transformations:
+
+- diffcore-pathspec
+- diffcore-break
+- diffcore-rename
+- diffcore-merge-broken
+- diffcore-pickaxe
+- diffcore-order
+
+These are applied in sequence.  The set of filepairs 'git-diff-{asterisk}'
+commands find are used as the input to diffcore-pathspec, and
+the output from diffcore-pathspec is used as the input to the
+next transformation.  The final result is then passed to the
+output routine and generates either diff-raw format (see Output
+format sections of the manual for 'git-diff-{asterisk}' commands) or
+diff-patch format.
+
+
+diffcore-pathspec: For Ignoring Files Outside Our Consideration
+---------------------------------------------------------------
+
+The first transformation in the chain is diffcore-pathspec, and
+is controlled by giving the pathname parameters to the
+'git-diff-{asterisk}' commands on the command line.  The pathspec is used
+to limit the world diff operates in.  It removes the filepairs
+outside the specified set of pathnames.  E.g. If the input set
+of filepairs included:
+
+------------------------------------------------
+:100644 100644 bcd1234... 0123456... M junkfile
+------------------------------------------------
+
+but the command invocation was `git diff-files myfile`, then the
+junkfile entry would be removed from the list because only "myfile"
+is under consideration.
+
+Implementation note.  For performance reasons, 'git-diff-tree'
+uses the pathname parameters on the command line to cull set of
+filepairs it feeds the diffcore mechanism itself, and does not
+use diffcore-pathspec, but the end result is the same.
+
+
+diffcore-break: For Splitting Up "Complete Rewrites"
+----------------------------------------------------
+
+The second transformation in the chain is diffcore-break, and is
+controlled by the -B option to the 'git-diff-{asterisk}' commands.  This is
+used to detect a filepair that represents "complete rewrite" and
+break such filepair into two filepairs that represent delete and
+create.  E.g.  If the input contained this filepair:
+
+------------------------------------------------
+:100644 100644 bcd1234... 0123456... M file0
+------------------------------------------------
+
+and if it detects that the file "file0" is completely rewritten,
+it changes it to:
+
+------------------------------------------------
+:100644 000000 bcd1234... 0000000... D file0
+:000000 100644 0000000... 0123456... A file0
+------------------------------------------------
+
+For the purpose of breaking a filepair, diffcore-break examines
+the extent of changes between the contents of the files before
+and after modification (i.e. the contents that have "bcd1234..."
+and "0123456..." as their SHA1 content ID, in the above
+example).  The amount of deletion of original contents and
+insertion of new material are added together, and if it exceeds
+the "break score", the filepair is broken into two.  The break
+score defaults to 50% of the size of the smaller of the original
+and the result (i.e. if the edit shrinks the file, the size of
+the result is used; if the edit lengthens the file, the size of
+the original is used), and can be customized by giving a number
+after "-B" option (e.g. "-B75" to tell it to use 75%).
+
+
+diffcore-rename: For Detection Renames and Copies
+-------------------------------------------------
+
+This transformation is used to detect renames and copies, and is
+controlled by the -M option (to detect renames) and the -C option
+(to detect copies as well) to the 'git-diff-{asterisk}' commands.  If the
+input contained these filepairs:
+
+------------------------------------------------
+:100644 000000 0123456... 0000000... D fileX
+:000000 100644 0000000... 0123456... A file0
+------------------------------------------------
+
+and the contents of the deleted file fileX is similar enough to
+the contents of the created file file0, then rename detection
+merges these filepairs and creates:
+
+------------------------------------------------
+:100644 100644 0123456... 0123456... R100 fileX file0
+------------------------------------------------
+
+When the "-C" option is used, the original contents of modified files,
+and deleted files (and also unmodified files, if the
+"\--find-copies-harder" option is used) are considered as candidates
+of the source files in rename/copy operation.  If the input were like
+these filepairs, that talk about a modified file fileY and a newly
+created file file0:
+
+------------------------------------------------
+:100644 100644 0123456... 1234567... M fileY
+:000000 100644 0000000... bcd3456... A file0
+------------------------------------------------
+
+the original contents of fileY and the resulting contents of
+file0 are compared, and if they are similar enough, they are
+changed to:
+
+------------------------------------------------
+:100644 100644 0123456... 1234567... M fileY
+:100644 100644 0123456... bcd3456... C100 fileY file0
+------------------------------------------------
+
+In both rename and copy detection, the same "extent of changes"
+algorithm used in diffcore-break is used to determine if two
+files are "similar enough", and can be customized to use
+a similarity score different from the default of 50% by giving a
+number after the "-M" or "-C" option (e.g. "-M8" to tell it to use
+8/10 = 80%).
+
+Note.  When the "-C" option is used with `\--find-copies-harder`
+option, 'git-diff-{asterisk}' commands feed unmodified filepairs to
+diffcore mechanism as well as modified ones.  This lets the copy
+detector consider unmodified files as copy source candidates at
+the expense of making it slower.  Without `\--find-copies-harder`,
+'git-diff-{asterisk}' commands can detect copies only if the file that was
+copied happened to have been modified in the same changeset.
+
+
+diffcore-merge-broken: For Putting "Complete Rewrites" Back Together
+--------------------------------------------------------------------
+
+This transformation is used to merge filepairs broken by
+diffcore-break, and not transformed into rename/copy by
+diffcore-rename, back into a single modification.  This always
+runs when diffcore-break is used.
+
+For the purpose of merging broken filepairs back, it uses a
+different "extent of changes" computation from the ones used by
+diffcore-break and diffcore-rename.  It counts only the deletion
+from the original, and does not count insertion.  If you removed
+only 10 lines from a 100-line document, even if you added 910
+new lines to make a new 1000-line document, you did not do a
+complete rewrite.  diffcore-break breaks such a case in order to
+help diffcore-rename to consider such filepairs as candidate of
+rename/copy detection, but if filepairs broken that way were not
+matched with other filepairs to create rename/copy, then this
+transformation merges them back into the original
+"modification".
+
+The "extent of changes" parameter can be tweaked from the
+default 80% (that is, unless more than 80% of the original
+material is deleted, the broken pairs are merged back into a
+single modification) by giving a second number to -B option,
+like these:
+
+* -B50/60 (give 50% "break score" to diffcore-break, use 60%
+  for diffcore-merge-broken).
+
+* -B/60 (the same as above, since diffcore-break defaults to 50%).
+
+Note that earlier implementation left a broken pair as a separate
+creation and deletion patches.  This was an unnecessary hack and
+the latest implementation always merges all the broken pairs
+back into modifications, but the resulting patch output is
+formatted differently for easier review in case of such
+a complete rewrite by showing the entire contents of old version
+prefixed with '-', followed by the entire contents of new
+version prefixed with '+'.
+
+
+diffcore-pickaxe: For Detecting Addition/Deletion of Specified String
+---------------------------------------------------------------------
+
+This transformation is used to find filepairs that represent
+changes that touch a specified string, and is controlled by the
+-S option and the `\--pickaxe-all` option to the 'git-diff-{asterisk}'
+commands.
+
+When diffcore-pickaxe is in use, it checks if there are
+filepairs whose "original" side has the specified string and
+whose "result" side does not.  Such a filepair represents "the
+string appeared in this changeset".  It also checks for the
+opposite case that loses the specified string.
+
+When `\--pickaxe-all` is not in effect, diffcore-pickaxe leaves
+only such filepairs that touch the specified string in its
+output.  When `\--pickaxe-all` is used, diffcore-pickaxe leaves all
+filepairs intact if there is such a filepair, or makes the
+output empty otherwise.  The latter behaviour is designed to
+make reviewing of the changes in the context of the whole
+changeset easier.
+
+
+diffcore-order: For Sorting the Output Based on Filenames
+---------------------------------------------------------
+
+This is used to reorder the filepairs according to the user's
+(or project's) taste, and is controlled by the -O option to the
+'git-diff-{asterisk}' commands.
+
+This takes a text file each of whose lines is a shell glob
+pattern.  Filepairs that match a glob pattern on an earlier line
+in the file are output before ones that match a later line, and
+filepairs that do not match any glob pattern are output last.
+
+As an example, a typical orderfile for the core git probably
+would look like this:
+
+------------------------------------------------
+README
+Makefile
+Documentation
+*.h
+*.c
+t

+githooks - Hooks used by git
+
+SYNOPSIS
+--------
+$GIT_DIR/hooks/*
+
+
+DESCRIPTION
+-----------
+
+Hooks are little scripts you can place in `$GIT_DIR/hooks`
+directory to trigger action at certain points.  When
+'git-init' is run, a handful example hooks are copied in the
+`hooks` directory of the new repository, but by default they are
+all disabled.  To enable a hook, rename it by removing its `.sample`
+suffix.
+
+This document describes the currently defined hooks.
+
+applypatch-msg
+--------------
+
+This hook is invoked by 'git-am' script.  It takes a single
+parameter, the name of the file that holds the proposed commit
+log message.  Exiting with non-zero status causes
+'git-am' to abort before applying the patch.
+
+The hook is allowed to edit the message file in place, and can
+be used to normalize the message into some project standard
+format (if the project has one). It can also be used to refuse
+the commit after inspecting the message file.
+
+The default 'applypatch-msg' hook, when enabled, runs the
+'commit-msg' hook, if the latter is enabled.
+
+pre-applypatch
+--------------
+
+This hook is invoked by 'git-am'.  It takes no parameter, and is
+invoked after the patch is applied, but before a commit is made.
+
+If it exits with non-zero status, then the working tree will not be
+committed after applying the patch.
+
+It can be used to inspect the current working tree and refuse to
+make a commit if it does not pass certain test.
+
+The default 'pre-applypatch' hook, when enabled, runs the
+'pre-commit' hook, if the latter is enabled.
+
+post-applypatch
+---------------
+
+This hook is invoked by 'git-am'.  It takes no parameter,
+and is invoked after the patch is applied and a commit is made.
+
+This hook is meant primarily for notification, and cannot affect
+the outcome of 'git-am'.
+
+pre-commit
+----------
+
+This hook is invoked by 'git-commit', and can be bypassed
+with `\--no-verify` option.  It takes no parameter, and is
+invoked before obtaining the proposed commit log message and
+making a commit.  Exiting with non-zero status from this script
+causes the 'git-commit' to abort.
+
+The default 'pre-commit' hook, when enabled, catches introduction
+of lines with trailing whitespaces and aborts the commit when
+such a line is found.
+
+All the 'git-commit' hooks are invoked with the environment
+variable `GIT_EDITOR=:` if the command will not bring up an editor
+to modify the commit message.
+
+prepare-commit-msg
+------------------
+
+This hook is invoked by 'git-commit' right after preparing the
+default log message, and before the editor is started.
+
+It takes one to three parameters.  The first is the name of the file
+that the commit log message.  The second is the source of the commit
+message, and can be: `message` (if a `\-m` or `\-F` option was
+given); `template` (if a `\-t` option was given or the
+configuration option `commit.template` is set); `merge` (if the
+commit is a merge or a `.git/MERGE_MSG` file exists); `squash`
+(if a `.git/SQUASH_MSG` file exists); or `commit`, followed by
+a commit SHA1 (if a `\-c`, `\-C` or `\--amend` option was given).
+
+If the exit status is non-zero, 'git-commit' will abort.
+
+The purpose of the hook is to edit the message file in place, and
+it is not suppressed by the `\--no-verify` option.  A non-zero exit
+means a failure of the hook and aborts the commit.  It should not
+be used as replacement for pre-commit hook.
+
+The sample `prepare-commit-msg` hook that comes with git comments
+out the `Conflicts:` part of a merge's commit message.
+
+commit-msg
+----------
+
+This hook is invoked by 'git-commit', and can be bypassed
+with `\--no-verify` option.  It takes a single parameter, the
+name of the file that holds the proposed commit log message.
+Exiting with non-zero status causes the 'git-commit' to
+abort.
+
+The hook is allowed to edit the message file in place, and can
+be used to normalize the message into some project standard
+format (if the project has one). It can also be used to refuse
+the commit after inspecting the message file.
+
+The default 'commit-msg' hook, when enabled, detects duplicate
+"Signed-off-by" lines, and aborts the commit if one is found.
+
+post-commit
+-----------
+
+This hook is invoked by 'git-commit'.  It takes no
+parameter, and is invoked after a commit is made.
+
+This hook is meant primarily for notification, and cannot affect
+the outcome of 'git-commit'.
+
+post-checkout
+-----------
+
+This hook is invoked when a 'git-checkout' is run after having updated the
+worktree.  The hook is given three parameters: the ref of the previous HEAD,
+the ref of the new HEAD (which may or may not have changed), and a flag
+indicating whether the checkout was a branch checkout (changing branches,
+flag=1) or a file checkout (retrieving a file from the index, flag=0).
+This hook cannot affect the outcome of 'git-checkout'.
+
+This hook can be used to perform repository validity checks, auto-display
+differences from the previous HEAD if different, or set working dir metadata
+properties.
+
+post-merge
+-----------
+
+This hook is invoked by 'git-merge', which happens when a 'git-pull'
+is done on a local repository.  The hook takes a single parameter, a status
+flag specifying whether or not the merge being done was a squash merge.
+This hook cannot affect the outcome of 'git-merge' and is not executed,
+if the merge failed due to conflicts.
+
+This hook can be used in conjunction with a corresponding pre-commit hook to
+save and restore any form of metadata associated with the working tree
+(eg: permissions/ownership, ACLS, etc).  See contrib/hooks/setgitperms.perl
+for an example of how to do this.
+
+[[pre-receive]]
+pre-receive
+-----------
+
+This hook is invoked by 'git-receive-pack' on the remote repository,
+which happens when a 'git-push' is done on a local repository.
+Just before starting to update refs on the remote repository, the
+pre-receive hook is invoked.  Its exit status determines the success
+or failure of the update.
+
+This hook executes once for the receive operation. It takes no
+arguments, but for each ref to be updated it receives on standard
+input a line of the format:
+
+  <old-value> SP <new-value> SP <ref-name> LF
+
+where `<old-value>` is the old object name stored in the ref,
+`<new-value>` is the new object name to be stored in the ref and
+`<ref-name>` is the full name of the ref.
+When creating a new ref, `<old-value>` is 40 `0`.
+
+If the hook exits with non-zero status, none of the refs will be
+updated. If the hook exits with zero, updating of individual refs can
+still be prevented by the <<update,'update'>> hook.
+
+Both standard output and standard error output are forwarded to
+'git-send-pack' on the other end, so you can simply `echo` messages
+for the user.
+
+[[update]]
+update
+------
+
+This hook is invoked by 'git-receive-pack' on the remote repository,
+which happens when a 'git-push' is done on a local repository.
+Just before updating the ref on the remote repository, the update hook
+is invoked.  Its exit status determines the success or failure of
+the ref update.
+
+The hook executes once for each ref to be updated, and takes
+three parameters:
+
+ - the name of the ref being updated,
+ - the old object name stored in the ref,
+ - and the new objectname to be stored in the ref.
+
+A zero exit from the update hook allows the ref to be updated.
+Exiting with a non-zero status prevents 'git-receive-pack'
+from updating that ref.
+
+This hook can be used to prevent 'forced' update on certain refs by
+making sure that the object name is a commit object that is a
+descendant of the commit object named by the old object name.
+That is, to enforce a "fast forward only" policy.
+
+It could also be used to log the old..new status.  However, it
+does not know the entire set of branches, so it would end up
+firing one e-mail per ref when used naively, though.  The
+<<post-receive,'post-receive'>> hook is more suited to that.
+
+Another use suggested on the mailing list is to use this hook to
+implement access control which is finer grained than the one
+based on filesystem group.
+
+Both standard output and standard error output are forwarded to
+'git-send-pack' on the other end, so you can simply `echo` messages
+for the user.
+
+The default 'update' hook, when enabled--and with
+`hooks.allowunannotated` config option turned on--prevents
+unannotated tags to be pushed.
+
+[[post-receive]]
+post-receive
+------------
+
+This hook is invoked by 'git-receive-pack' on the remote repository,
+which happens when a 'git-push' is done on a local repository.
+It executes on the remote repository once after all the refs have
+been updated.
+
+This hook executes once for the receive operation.  It takes no
+arguments, but gets the same information as the
+<<pre-receive,'pre-receive'>>
+hook does on its standard input.
+
+This hook does not affect the outcome of 'git-receive-pack', as it
+is called after the real work is done.
+
+This supersedes the <<post-update,'post-update'>> hook in that it gets
+both old and new values of all the refs in addition to their
+names.
+
+Both standard output and standard error output are forwarded to
+'git-send-pack' on the other end, so you can simply `echo` messages
+for the user.
+
+The default 'post-receive' hook is empty, but there is
+a sample script `post-receive-email` provided in the `contrib/hooks`
+directory in git distribution, which implements sending commit
+emails.
+
+[[post-update]]
+post-update
+-----------
+
+This hook is invoked by 'git-receive-pack' on the remote repository,
+which happens when a 'git-push' is done on a local repository.
+It executes on the remote repository once after all the refs have
+been updated.
+
+It takes a variable number of parameters, each of which is the
+name of ref that was actually updated.
+
+This hook is meant primarily for notification, and cannot affect
+the outcome of 'git-receive-pack'.
+
+The 'post-update' hook can tell what are the heads that were pushed,
+but it does not know what their original and updated values are,
+so it is a poor place to do log old..new. The
+<<post-receive,'post-receive'>> hook does get both original and
+updated values of the refs. You might consider it instead if you need
+them.
+
+When enabled, the default 'post-update' hook runs
+'git-update-server-info' to keep the information used by dumb
+transports (e.g., HTTP) up-to-date.  If you are publishing
+a git repository that is accessible via HTTP, you should
+probably enable this hook.
+
+Both standard output and standard error output are forwarded to
+'git-send-pack' on the other end, so you can simply `echo` messages
+for the user.
+
+pre-auto-gc
+-----------
+
+This hook is invoked by 'git-gc --auto'. It takes no parameter, and
+exiting with non-zero status from this script causes the 'git-gc --auto'
+to abort.

+=======================
+
+NAME
+----
+gitrepository-layout - Git Repository Layout
+
+SYNOPSIS
+--------
+$GIT_DIR/*
+
+DESCRIPTION
+-----------
+
+You may find these things in your git repository (`.git`
+directory for a repository associated with your working tree, or
+`<project>.git` directory for a public 'bare' repository. It is
+also possible to have a working tree where `.git` is a plain
+ascii file containing `gitdir: <path>`, i.e. the path to the
+real git repository).
+
+objects::
+       Object store associated with this repository.  Usually
+       an object store is self sufficient (i.e. all the objects
+       that are referred to by an object found in it are also
+       found in it), but there are couple of ways to violate
+       it.
++
+. You could populate the repository by running a commit walker
+without `-a` option.  Depending on which options are given, you
+could have only commit objects without associated blobs and
+trees this way, for example.  A repository with this kind of
+incomplete object store is not suitable to be published to the
+outside world but sometimes useful for private repository.
+. You also could have an incomplete but locally usable repository
+by cloning shallowly.  See linkgit:git-clone[1].
+. You can be using `objects/info/alternates` mechanism, or
+`$GIT_ALTERNATE_OBJECT_DIRECTORIES` mechanism to 'borrow'
+objects from other object stores.  A repository with this kind
+of incomplete object store is not suitable to be published for
+use with dumb transports but otherwise is OK as long as
+`objects/info/alternates` points at the right object stores
+it borrows from.
+
+objects/[0-9a-f][0-9a-f]::
+       Traditionally, each object is stored in its own file.
+       They are split into 256 subdirectories using the first
+       two letters from its object name to keep the number of
+       directory entries `objects` directory itself needs to
+       hold.  Objects found here are often called 'unpacked'
+       (or 'loose') objects.
+
+objects/pack::
+       Packs (files that store many object in compressed form,
+       along with index files to allow them to be randomly
+       accessed) are found in this directory.
+
+objects/info::
+       Additional information about the object store is
+       recorded in this directory.
+
+objects/info/packs::
+       This file is to help dumb transports discover what packs
+       are available in this object store.  Whenever a pack is
+       added or removed, `git update-server-info` should be run
+       to keep this file up-to-date if the repository is
+       published for dumb transports.  'git-repack' does this
+       by default.
+
+objects/info/alternates::
+       This file records paths to alternate object stores that
+       this object store borrows objects from, one pathname per
+       line. Note that not only native Git tools use it locally,
+       but the HTTP fetcher also tries to use it remotely; this
+       will usually work if you have relative paths (relative
+       to the object database, not to the repository!) in your
+       alternates file, but it will not work if you use absolute
+       paths unless the absolute path in filesystem and web URL
+       is the same. See also 'objects/info/http-alternates'.
+
+objects/info/http-alternates::
+       This file records URLs to alternate object stores that
+       this object store borrows objects from, to be used when
+       the repository is fetched over HTTP.
+
+refs::
+       References are stored in subdirectories of this
+       directory.  The 'git-prune' command knows to keep
+       objects reachable from refs found in this directory and
+       its subdirectories.
+
+refs/heads/`name`::
+       records tip-of-the-tree commit objects of branch `name`
+
+refs/tags/`name`::
+       records any object name (not necessarily a commit
+       object, or a tag object that points at a commit object).
+
+refs/remotes/`name`::
+       records tip-of-the-tree commit objects of branches copied
+       from a remote repository.
+
+packed-refs::
+       records the same information as refs/heads/, refs/tags/,
+       and friends record in a more efficient way.  See
+       linkgit:git-pack-refs[1].
+
+HEAD::
+       A symref (see glossary) to the `refs/heads/` namespace
+       describing the currently active branch.  It does not mean
+       much if the repository is not associated with any working tree
+       (i.e. a 'bare' repository), but a valid git repository
+       *must* have the HEAD file; some porcelains may use it to
+       guess the designated "default" branch of the repository
+       (usually 'master').  It is legal if the named branch
+       'name' does not (yet) exist.  In some legacy setups, it is
+       a symbolic link instead of a symref that points at the current
+       branch.
++
+HEAD can also record a specific commit directly, instead of
+being a symref to point at the current branch.  Such a state
+is often called 'detached HEAD', and almost all commands work
+identically as normal.  See linkgit:git-checkout[1] for
+details.
+
+branches::
+       A slightly deprecated way to store shorthands to be used
+       to specify URL to 'git-fetch', 'git-pull' and 'git-push'
+       commands is to store a file in `branches/<name>` and
+       give 'name' to these commands in place of 'repository'
+       argument.
+
+hooks::
+       Hooks are customization scripts used by various git
+       commands.  A handful of sample hooks are installed when
+       'git-init' is run, but all of them are disabled by
+       default.  To enable, they need to be made executable.
+       Read linkgit:githooks[5] for more details about
+       each hook.
+
+index::
+       The current index file for the repository.  It is
+       usually not found in a bare repository.
+
+info::
+       Additional information about the repository is recorded
+       in this directory.
+
+info/refs::
+       This file helps dumb transports discover what refs are
+       available in this repository.  If the repository is
+       published for dumb transports, this file should be
+       regenerated by 'git-update-server-info' every time a tag
+       or branch is created or modified.  This is normally done
+       from the `hooks/update` hook, which is run by the
+       'git-receive-pack' command when you 'git-push' into the
+       repository.
+
+info/grafts::
+       This file records fake commit ancestry information, to
+       pretend the set of parents a commit has is different
+       from how the commit was actually created.  One record
+       per line describes a commit and its fake parents by
+       listing their 40-byte hexadecimal object names separated
+       by a space and terminated by a newline.
+
+info/exclude::
+       This file, by convention among Porcelains, stores the
+       exclude pattern list. `.gitignore` is the per-directory
+       ignore file.  'git-status', 'git-add', 'git-rm' and
+       'git-clean' look at it but the core git commands do not look
+       at it.  See also: linkgit:gitignore[5].
+
+remotes::
+       Stores shorthands to be used to give URL and default
+       refnames to interact with remote repository to
+       'git-fetch', 'git-pull' and 'git-push' commands.
+
+logs::
+       Records of changes made to refs are stored in this
+       directory.  See linkgit:git-update-ref[1]
+       for more information.
+
+logs/refs/heads/`name`::
+       Records all changes made to the branch tip named `name`.
+
+logs/refs/tags/`name`::
+       Records all changes made to the tag named `name`.
+
+shallow::
+       This is similar to `info/grafts` but is internally used
+       and maintained by shallow clone mechanism.  See `--depth`
+       option to linkgit:git-clone[1] and linkgit:git-fetch[1].

+NAME
+----
+gittutorial-2 - A tutorial introduction to git: part two
+
+SYNOPSIS
+--------
+git *
+
+DESCRIPTION
+-----------
+
+You should work through linkgit:gittutorial[7] before reading this tutorial.
+
+The goal of this tutorial is to introduce two fundamental pieces of
+git's architecture--the object database and the index file--and to
+provide the reader with everything necessary to understand the rest
+of the git documentation.
+
+The git object database
+-----------------------
+
+Let's start a new project and create a small amount of history:
+
+------------------------------------------------
+$ mkdir test-project
+$ cd test-project
+$ git init
+Initialized empty Git repository in .git/
+$ echo 'hello world' > file.txt
+$ git add .
+$ git commit -a -m "initial commit"
+Created initial commit 54196cc2703dc165cbd373a65a4dcf22d50ae7f7
+ create mode 100644 file.txt
+$ echo 'hello world!' >file.txt
+$ git commit -a -m "add emphasis"
+Created commit c4d59f390b9cfd4318117afde11d601c1085f241
+------------------------------------------------
+
+What are the 40 digits of hex that git responded to the commit with?
+
+We saw in part one of the tutorial that commits have names like this.
+It turns out that every object in the git history is stored under
+such a 40-digit hex name.  That name is the SHA1 hash of the object's
+contents; among other things, this ensures that git will never store
+the same data twice (since identical data is given an identical SHA1
+name), and that the contents of a git object will never change (since
+that would change the object's name as well).
+
+It is expected that the content of the commit object you created while
+following the example above generates a different SHA1 hash than
+the one shown above because the commit object records the time when
+it was created and the name of the person performing the commit.
+
+We can ask git about this particular object with the `cat-file`
+command. Don't copy the 40 hex digits from this example but use those
+from your own version. Note that you can shorten it to only a few
+characters to save yourself typing all 40 hex digits:
+
+------------------------------------------------
+$ git cat-file -t 54196cc2
+commit
+$ git cat-file commit 54196cc2
+tree 92b8b694ffb1675e5975148e1121810081dbdffe
+author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+
+initial commit
+------------------------------------------------
+
+A tree can refer to one or more "blob" objects, each corresponding to
+a file.  In addition, a tree can also refer to other tree objects,
+thus creating a directory hierarchy.  You can examine the contents of
+any tree using ls-tree (remember that a long enough initial portion
+of the SHA1 will also work):
+
+------------------------------------------------
+$ git ls-tree 92b8b694
+100644 blob 3b18e512dba79e4c8300dd08aeb37f8e728b8dad    file.txt
+------------------------------------------------
+
+Thus we see that this tree has one file in it.  The SHA1 hash is a
+reference to that file's data:
+
+------------------------------------------------
+$ git cat-file -t 3b18e512
+blob
+------------------------------------------------
+
+A "blob" is just file data, which we can also examine with cat-file:
+
+------------------------------------------------
+$ git cat-file blob 3b18e512
+hello world
+------------------------------------------------
+
+Note that this is the old file data; so the object that git named in
+its response to the initial tree was a tree with a snapshot of the
+directory state that was recorded by the first commit.
+
+All of these objects are stored under their SHA1 names inside the git
+directory:
+
+------------------------------------------------
+$ find .git/objects/
+.git/objects/
+.git/objects/pack
+.git/objects/info
+.git/objects/3b
+.git/objects/3b/18e512dba79e4c8300dd08aeb37f8e728b8dad
+.git/objects/92
+.git/objects/92/b8b694ffb1675e5975148e1121810081dbdffe
+.git/objects/54
+.git/objects/54/196cc2703dc165cbd373a65a4dcf22d50ae7f7
+.git/objects/a0
+.git/objects/a0/423896973644771497bdc03eb99d5281615b51
+.git/objects/d0
+.git/objects/d0/492b368b66bdabf2ac1fd8c92b39d3db916e59
+.git/objects/c4
+.git/objects/c4/d59f390b9cfd4318117afde11d601c1085f241
+------------------------------------------------
+
+and the contents of these files is just the compressed data plus a
+header identifying their length and their type.  The type is either a
+blob, a tree, a commit, or a tag.
+
+The simplest commit to find is the HEAD commit, which we can find
+from .git/HEAD:
+
+------------------------------------------------
+$ cat .git/HEAD
+ref: refs/heads/master
+------------------------------------------------
+
+As you can see, this tells us which branch we're currently on, and it
+tells us this by naming a file under the .git directory, which itself
+contains a SHA1 name referring to a commit object, which we can
+examine with cat-file:
+
+------------------------------------------------
+$ cat .git/refs/heads/master
+c4d59f390b9cfd4318117afde11d601c1085f241
+$ git cat-file -t c4d59f39
+commit
+$ git cat-file commit c4d59f39
+tree d0492b368b66bdabf2ac1fd8c92b39d3db916e59
+parent 54196cc2703dc165cbd373a65a4dcf22d50ae7f7

+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143418702 -0500
+
+add emphasis
+------------------------------------------------
+
+The "tree" object here refers to the new state of the tree:
+
+------------------------------------------------
+$ git ls-tree d0492b36
+100644 blob a0423896973644771497bdc03eb99d5281615b51    file.txt
+$ git cat-file blob a0423896
+hello world!
+------------------------------------------------
+
+and the "parent" object refers to the previous commit:
+
+------------------------------------------------
+$ git cat-file commit 54196cc2
+tree 92b8b694ffb1675e5975148e1121810081dbdffe
+author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+
+initial commit
+------------------------------------------------
+
+The tree object is the tree we examined first, and this commit is
+unusual in that it lacks any parent.
+
+Most commits have only one parent, but it is also common for a commit
+to have multiple parents.   In that case the commit represents a
+merge, with the parent references pointing to the heads of the merged
+branches.
+
+Besides blobs, trees, and commits, the only remaining type of object
+is a "tag", which we won't discuss here; refer to linkgit:git-tag[1]
+for details.
+
+So now we know how git uses the object database to represent a
+project's history:
+
+  * "commit" objects refer to "tree" objects representing the
+    snapshot of a directory tree at a particular point in the
+    history, and refer to "parent" commits to show how they're
+    connected into the project history.
+  * "tree" objects represent the state of a single directory,
+    associating directory names to "blob" objects containing file
+    data and "tree" objects containing subdirectory information.
+  * "blob" objects contain file data without any other structure.
+  * References to commit objects at the head of each branch are
+    stored in files under .git/refs/heads/.
+  * The name of the current branch is stored in .git/HEAD.
+
+Note, by the way, that lots of commands take a tree as an argument.
+But as we can see above, a tree can be referred to in many different
+ways--by the SHA1 name for that tree, by the name of a commit that
+refers to the tree, by the name of a branch whose head refers to that
+tree, etc.--and most such commands can accept any of these names.
+
+In command synopses, the word "tree-ish" is sometimes used to
+designate such an argument.
+
+The index file
+--------------
+
+The primary tool we've been using to create commits is `git-commit
+-a`, which creates a commit including every change you've made to
+your working tree.  But what if you want to commit changes only to
+certain files?  Or only certain changes to certain files?
+
+If we look at the way commits are created under the cover, we'll see
+that there are more flexible ways creating commits.
+
+Continuing with our test-project, let's modify file.txt again:
+
+------------------------------------------------
+$ echo "hello world, again" >>file.txt
+------------------------------------------------
+
+but this time instead of immediately making the commit, let's take an
+intermediate step, and ask for diffs along the way to keep track of
+what's happening:
+
+------------------------------------------------
+$ git diff
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+$ git add file.txt
+$ git diff
+------------------------------------------------
+
+The last diff is empty, but no new commits have been made, and the
+head still doesn't contain the new line:
+
+------------------------------------------------
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index a042389..513feba 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+------------------------------------------------
+
+So 'git-diff' is comparing against something other than the head.
+The thing that it's comparing against is actually the index file,
+which is stored in .git/index in a binary format, but whose contents
+we can examine with ls-files:
+
+------------------------------------------------
+$ git ls-files --stage
+100644 513feba2e53ebbd2532419ded848ba19de88ba00 0       file.txt
+$ git cat-file -t 513feba2
+blob
+$ git cat-file blob 513feba2
+hello world!
+hello world, again
+------------------------------------------------
+
+So what our 'git-add' did was store a new blob and then put
+a reference to it in the index file.  If we modify the file again,
+we'll see that the new modifications are reflected in the 'git-diff'
+output:
+
+------------------------------------------------
+$ echo 'again?' >>file.txt
+$ git diff
+index 513feba..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1,2 +1,3 @@
+ hello world!
+ hello world, again
++again?
+------------------------------------------------
+
+With the right arguments, 'git-diff' can also show us the difference
+between the working directory and the last commit, or between the
+index and the last commit:
+
+------------------------------------------------
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index a042389..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,3 @@
+ hello world!
++hello world, again
++again?
+$ git diff --cached

+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+------------------------------------------------
+
+At any time, we can create a new commit using 'git-commit' (without
+the "-a" option), and verify that the state committed only includes the
+changes stored in the index file, not the additional change that is
+still only in our working tree:
+
+------------------------------------------------
+$ git commit -m "repeat"
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index 513feba..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1,2 +1,3 @@
+ hello world!
+ hello world, again
++again?
+------------------------------------------------
+
+So by default 'git-commit' uses the index to create the commit, not
+the working tree; the "-a" option to commit tells it to first update
+the index with all changes in the working tree.
+
+Finally, it's worth looking at the effect of 'git-add' on the index
+file:
+
+------------------------------------------------
+$ echo "goodbye, world" >closing.txt
+$ git add closing.txt
+------------------------------------------------
+
+The effect of the 'git-add' was to add one entry to the index file:
+
+------------------------------------------------
+$ git ls-files --stage
+100644 8b9743b20d4b15be3955fc8d5cd2b09cd2336138 0       closing.txt
+100644 513feba2e53ebbd2532419ded848ba19de88ba00 0       file.txt
+------------------------------------------------
+
+And, as you can see with cat-file, this new entry refers to the
+current contents of the file:
+
+------------------------------------------------
+$ git cat-file blob 8b9743b2
+goodbye, world
+------------------------------------------------
+
+The "status" command is a useful way to get a quick summary of the
+situation:
+
+------------------------------------------------
+$ git status
+# On branch master
+# Changes to be committed:
+#   (use "git reset HEAD <file>..." to unstage)
+#
+#       new file: closing.txt
+#
+# Changed but not updated:
+#   (use "git add <file>..." to update what will be committed)
+#
+#       modified: file.txt
+#
+------------------------------------------------
+
+Since the current state of closing.txt is cached in the index file,
+it is listed as "Changes to be committed".  Since file.txt has
+changes in the working directory that aren't reflected in the index,
+it is marked "changed but not updated".  At this point, running "git
+commit" would create a commit that added closing.txt (with its new
+contents), but that didn't modify file.txt.
+
+Also, note that a bare `git diff` shows the changes to file.txt, but
+not the addition of closing.txt, because the version of closing.txt
+in the index file is identical to the one in the working directory.
+
+In addition to being the staging area for new commits, the index file
+is also populated from the object database when checking out a
+branch, and is used to hold the trees involved in a merge operation.
+See linkgit:gitcore-tutorial[7] and the relevant man
+pages for details.
+
+What next?
+----------
+
+At this point you should know everything necessary to read the man
+pages for any of the git commands; one good place to start would be
+with the commands mentioned in link:everyday.html[Everyday git].  You
+should be able to find any unknown jargon in linkgit:gitglossary[7].
+
+The link:user-manual.html[Git User's Manual] provides a more
+comprehensive introduction to git.
+
+linkgit:gitcvs-migration[7] explains how to
+import a CVS repository into git, and shows how to use git in a
+CVS-like way.
+
+For some interesting examples of git use, see the
+link:howto-index.html[howtos].
+
+For git developers, linkgit:gitcore-tutorial[7] goes

+NAME
+----
+gittutorial - A tutorial introduction to git (for version 1.5.1 or newer)
+
+SYNOPSIS
+--------
+git *
+
+DESCRIPTION
+-----------
+
+This tutorial explains how to import a new project into git, make
+changes to it, and share changes with other developers.
+
+If you are instead primarily interested in using git to fetch a project,
+for example, to test the latest version, you may prefer to start with
+the first two chapters of link:user-manual.html[The Git User's Manual].
+
+First, note that you can get documentation for a command such as
+`git log --graph` with:
+
+------------------------------------------------
+$ man git-log
+------------------------------------------------
+
+It is a good idea to introduce yourself to git with your name and
+public email address before doing any operation.  The easiest
+way to do so is:
+
+------------------------------------------------
+$ git config --global user.name "Your Name Comes Here"
+$ git config --global user.email you@yourdomain.example.com
+------------------------------------------------
+
+
+Importing a new project
+-----------------------
+
+Assume you have a tarball project.tar.gz with your initial work.  You
+can place it under git revision control as follows.
+
+------------------------------------------------
+$ tar xzf project.tar.gz
+$ cd project
+$ git init
+------------------------------------------------
+
+Git will reply
+
+------------------------------------------------
+Initialized empty Git repository in .git/
+------------------------------------------------
+
+You've now initialized the working directory--you may notice a new
+directory created, named ".git".
+
+Next, tell git to take a snapshot of the contents of all files under the
+current directory (note the '.'), with 'git-add':
+
+------------------------------------------------
+$ git add .
+------------------------------------------------
+
+This snapshot is now stored in a temporary staging area which git calls
+the "index".  You can permanently store the contents of the index in the
+repository with 'git-commit':
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+This will prompt you for a commit message.  You've now stored the first
+version of your project in git.
+
+Making changes
+--------------
+
+Modify some files, then add their updated contents to the index:
+
+------------------------------------------------
+$ git add file1 file2 file3
+------------------------------------------------
+
+You are now ready to commit.  You can see what is about to be committed
+using 'git-diff' with the --cached option:
+
+------------------------------------------------
+$ git diff --cached
+------------------------------------------------
+
+(Without --cached, 'git-diff' will show you any changes that
+you've made but not yet added to the index.)  You can also get a brief
+summary of the situation with 'git-status':
+
+------------------------------------------------
+$ git status
+# On branch master
+# Changes to be committed:
+#   (use "git reset HEAD <file>..." to unstage)
+#
+#      modified:   file1
+#      modified:   file2
+#      modified:   file3
+#
+------------------------------------------------
+
+If you need to make any further adjustments, do so now, and then add any
+newly modified content to the index.  Finally, commit your changes with:
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+This will again prompt you for a message describing the change, and then
+record a new version of the project.
+
+Alternatively, instead of running 'git-add' beforehand, you can use
+
+------------------------------------------------
+$ git commit -a
+------------------------------------------------
+
+which will automatically notice any modified (but not new) files, add
+them to the index, and commit, all in one step.
+
+A note on commit messages: Though not required, it's a good idea to
+begin the commit message with a single short (less than 50 character)
+line summarizing the change, followed by a blank line and then a more
+thorough description.  Tools that turn commits into email, for
+example, use the first line on the Subject: line and the rest of the
+commit in the body.
+
+Git tracks content not files
+----------------------------
+
+Many revision control systems provide an `add` command that tells the
+system to start tracking changes to a new file.  Git's `add` command
+does something simpler and more powerful: 'git-add' is used both for new
+and newly modified files, and in both cases it takes a snapshot of the
+given files and stages that content in the index, ready for inclusion in
+the next commit.
+
+Viewing project history
+-----------------------
+
+At any point you can view the history of your changes using
+
+------------------------------------------------
+$ git log
+------------------------------------------------
+
+If you also want to see complete diffs at each step, use
+
+------------------------------------------------
+$ git log -p
+------------------------------------------------
+
+Often the overview of the change is useful to get a feel of
+each step
+
+------------------------------------------------
+$ git log --stat --summary
+------------------------------------------------
+
+Managing branches
+-----------------
+
+A single git repository can maintain multiple branches of
+development.  To create a new branch named "experimental", use
+
+------------------------------------------------
+$ git branch experimental
+------------------------------------------------
+
+If you now run
+
+------------------------------------------------
+$ git branch
+------------------------------------------------
+
+you'll get a list of all existing branches:
+
+------------------------------------------------
+  experimental
+* master
+------------------------------------------------
+
+The "experimental" branch is the one you just created, and the
+"master" branch is a default branch that was created for you
+automatically.  The asterisk marks the branch you are currently on;
+type
+
+------------------------------------------------
+$ git checkout experimental
+------------------------------------------------
+
+to switch to the experimental branch.  Now edit a file, commit the
+change, and switch back to the master branch:
+
+------------------------------------------------
+(edit file)
+$ git commit -a
+$ git checkout master
+------------------------------------------------
+
+Check that the change you made is no longer visible, since it was
+made on the experimental branch and you're back on the master branch.
+
+You can make a different change on the master branch:
+
+------------------------------------------------
+(edit file)
+$ git commit -a
+------------------------------------------------
+
+at this point the two branches have diverged, with different changes
+made in each.  To merge the changes made in experimental into master, run
+
+------------------------------------------------
+$ git merge experimental
+------------------------------------------------
+
+If the changes don't conflict, you're done.  If there are conflicts,
+markers will be left in the problematic files showing the conflict;
+
+------------------------------------------------
+$ git diff
+------------------------------------------------
+
+will show this.  Once you've edited the files to resolve the
+conflicts,
+
+------------------------------------------------
+$ git commit -a
+------------------------------------------------
+
+will commit the result of the merge. Finally,
+
+------------------------------------------------
+$ gitk
+------------------------------------------------
+
+will show a nice graphical representation of the resulting history.
+
+At this point you could delete the experimental branch with
+
+------------------------------------------------
+$ git branch -d experimental
+------------------------------------------------
+
+This command ensures that the changes in the experimental branch are
+already in the current branch.
+
+If you develop on a branch crazy-idea, then regret it, you can always
+delete the branch with
+
+-------------------------------------
+$ git branch -D crazy-idea
+-------------------------------------
+
+Branches are cheap and easy, so this is a good way to try something
+out.
+
+Using git for collaboration
+---------------------------
+
+Suppose that Alice has started a new project with a git repository in
+/home/alice/project, and that Bob, who has a home directory on the
+same machine, wants to contribute.
+
+Bob begins with:
+
+------------------------------------------------
+bob$ git clone /home/alice/project myrepo
+------------------------------------------------
+
+This creates a new directory "myrepo" containing a clone of Alice's
+repository.  The clone is on an equal footing with the original
+project, possessing its own copy of the original project's history.
+
+Bob then makes some changes and commits them:
+
+------------------------------------------------
+(edit files)
+bob$ git commit -a
+(repeat as necessary)
+------------------------------------------------
+
+When he's ready, he tells Alice to pull changes from the repository
+at /home/bob/myrepo.  She does this with:
+
+------------------------------------------------
+alice$ cd /home/alice/project
+alice$ git pull /home/bob/myrepo master
+------------------------------------------------
+
+This merges the changes from Bob's "master" branch into Alice's
+current branch.  If Alice has made her own changes in the meantime,
+then she may need to manually fix any conflicts.  (Note that the
+"master" argument in the above command is actually unnecessary, as it
+is the default.)
+
+The "pull" command thus performs two operations: it fetches changes
+from a remote branch, then merges them into the current branch.
+
+Note that in general, Alice would want her local changes committed before
+initiating this "pull".  If Bob's work conflicts with what Alice did since
+their histories forked, Alice will use her working tree and the index to
+resolve conflicts, and existing local changes will interfere with the
+conflict resolution process (git will still perform the fetch but will
+refuse to merge --- Alice will have to get rid of her local changes in
+some way and pull again when this happens).
+
+Alice can peek at what Bob did without merging first, using the "fetch"
+command; this allows Alice to inspect what Bob did, using a special
+symbol "FETCH_HEAD", in order to determine if he has anything worth
+pulling, like this:
+
+------------------------------------------------
+alice$ git fetch /home/bob/myrepo master
+alice$ git log -p ..FETCH_HEAD
+------------------------------------------------
+
+This operation is safe even if Alice has uncommitted local changes.
+
+After inspecting what Bob did, if there is nothing urgent, Alice may
+decide to continue working without pulling from Bob.  If Bob's history
+does have something Alice would immediately need, Alice may choose to
+stash her work-in-progress first, do a "pull", and then finally unstash
+her work-in-progress on top of the resulting history.
+
+When you are working in a small closely knit group, it is not
+unusual to interact with the same repository over and over
+again.  By defining 'remote' repository shorthand, you can make
+it easier:
+
+------------------------------------------------
+alice$ git remote add bob /home/bob/myrepo
+------------------------------------------------
+
+With this, Alice can perform the first part of the "pull" operation alone using the
+'git-fetch' command without merging them with her own branch,
+using:
+
+-------------------------------------
+alice$ git fetch bob
+-------------------------------------
+
+Unlike the longhand form, when Alice fetches from Bob using a
+remote repository shorthand set up with 'git-remote', what was
+fetched is stored in a remote tracking branch, in this case
+`bob/master`.  So after this:
+
+-------------------------------------
+alice$ git log -p master..bob/master
+-------------------------------------
+
+shows a list of all the changes that Bob made since he branched from
+Alice's master branch.
+
+After examining those changes, Alice
+could merge the changes into her master branch:
+
+-------------------------------------
+alice$ git merge bob/master
+-------------------------------------
+
+This `merge` can also be done by 'pulling from her own remote
+tracking branch', like this:
+
+-------------------------------------
+alice$ git pull . remotes/bob/master
+-------------------------------------
+
+Note that git pull always merges into the current branch,
+regardless of what else is given on the command line.
+
+Later, Bob can update his repo with Alice's latest changes using
+
+-------------------------------------
+bob$ git pull
+-------------------------------------
+
+Note that he doesn't need to give the path to Alice's repository;
+when Bob cloned Alice's repository, git stored the location of her
+repository in the repository configuration, and that location is
+used for pulls:
+
+-------------------------------------
+bob$ git config --get remote.origin.url
+/home/alice/project
+-------------------------------------
+
+(The complete configuration created by 'git-clone' is visible using
+`git config -l`, and the linkgit:git-config[1] man page
+explains the meaning of each option.)
+
+Git also keeps a pristine copy of Alice's master branch under the
+name "origin/master":
+
+-------------------------------------
+bob$ git branch -r
+  origin/master
+-------------------------------------
+
+If Bob later decides to work from a different host, he can still
+perform clones and pulls using the ssh protocol:
+
+-------------------------------------
+bob$ git clone alice.org:/home/alice/project myrepo
+-------------------------------------
+
+Alternatively, git has a native protocol, or can use rsync or http;
+see linkgit:git-pull[1] for details.
+
+Git can also be used in a CVS-like mode, with a central repository
+that various users push changes to; see linkgit:git-push[1] and
+linkgit:gitcvs-migration[7].
+
+Exploring history
+-----------------
+
+Git history is represented as a series of interrelated commits.  We
+have already seen that the 'git-log' command can list those commits.
+Note that first line of each git log entry also gives a name for the
+commit:
+
+-------------------------------------
+$ git log
+commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+Author: Junio C Hamano <junkio@cox.net>
+Date:   Tue May 16 17:18:22 2006 -0700
+
+    merge-base: Clarify the comments on post processing.
+-------------------------------------
+
+We can give this name to 'git-show' to see the details about this
+commit.
+
+-------------------------------------
+$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+-------------------------------------
+
+But there are other ways to refer to commits.  You can use any initial
+part of the name that is long enough to uniquely identify the commit:
+
+-------------------------------------
+$ git show c82a22c39c  # the first few characters of the name are
+                       # usually enough
+$ git show HEAD                # the tip of the current branch
+$ git show experimental        # the tip of the "experimental" branch
+-------------------------------------
+
+Every commit usually has one "parent" commit
+which points to the previous state of the project:
+
+-------------------------------------
+$ git show HEAD^  # to see the parent of HEAD
+$ git show HEAD^^ # to see the grandparent of HEAD
+$ git show HEAD~4 # to see the great-great grandparent of HEAD
+-------------------------------------
+
+Note that merge commits may have more than one parent:
+
+-------------------------------------
+$ git show HEAD^1 # show the first parent of HEAD (same as HEAD^)
+$ git show HEAD^2 # show the second parent of HEAD
+-------------------------------------
+
+You can also give commits names of your own; after running
+
+-------------------------------------
+$ git tag v2.5 1b2e1d63ff
+-------------------------------------
+
+you can refer to 1b2e1d63ff by the name "v2.5".  If you intend to
+share this name with other people (for example, to identify a release
+version), you should create a "tag" object, and perhaps sign it; see
+linkgit:git-tag[1] for details.
+
+Any git command that needs to know a commit can take any of these
+names.  For example:
+
+-------------------------------------
+$ git diff v2.5 HEAD    # compare the current HEAD to v2.5
+$ git branch stable v2.5 # start a new branch named "stable" based
+                        # at v2.5
+$ git reset --hard HEAD^ # reset your current branch and working
+                        # directory to its state at HEAD^
+-------------------------------------
+
+Be careful with that last command: in addition to losing any changes
+in the working directory, it will also remove all later commits from
+this branch.  If this branch is the only branch containing those
+commits, they will be lost.  Also, don't use 'git-reset' on a
+publicly-visible branch that other developers pull from, as it will
+force needless merges on other developers to clean up the history.
+If you need to undo changes that you have pushed, use 'git-revert'
+instead.
+
+The 'git-grep' command can search for strings in any version of your
+project, so
+
+-------------------------------------
+$ git grep "hello" v2.5
+-------------------------------------
+
+searches for all occurrences of "hello" in v2.5.
+
+If you leave out the commit name, 'git-grep' will search any of the
+files it manages in your current directory.  So
+
+-------------------------------------
+$ git grep "hello"
+-------------------------------------
+
+is a quick way to search just the files that are tracked by git.
+
+Many git commands also take sets of commits, which can be specified
+in a number of ways.  Here are some examples with 'git-log':
+
+-------------------------------------
+$ git log v2.5..v2.6            # commits between v2.5 and v2.6
+$ git log v2.5..                # commits since v2.5
+$ git log --since="2 weeks ago" # commits from the last 2 weeks
+$ git log v2.5.. Makefile       # commits since v2.5 which modify
+                               # Makefile
+-------------------------------------
+
+You can also give 'git-log' a "range" of commits where the first is not
+necessarily an ancestor of the second; for example, if the tips of
+the branches "stable-release" and "master" diverged from a common
+commit some time ago, then
+
+-------------------------------------
+$ git log stable..experimental
+-------------------------------------
+
+will list commits made in the experimental branch but not in the
+stable branch, while
+
+-------------------------------------
+$ git log experimental..stable
+-------------------------------------
+
+will show the list of commits made on the stable branch but not
+the experimental branch.
+
+The 'git-log' command has a weakness: it must present commits in a
+list.  When the history has lines of development that diverged and
+then merged back together, the order in which 'git-log' presents
+those commits is meaningless.
+
+Most projects with multiple contributors (such as the linux kernel,
+or git itself) have frequent merges, and 'gitk' does a better job of
+visualizing their history.  For example,
+
+-------------------------------------
+$ gitk --since="2 weeks ago" drivers/
+-------------------------------------
+
+allows you to browse any commits from the last 2 weeks of commits
+that modified files under the "drivers" directory.  (Note: you can
+adjust gitk's fonts by holding down the control key while pressing
+"-" or "+".)
+
+Finally, most commands that take filenames will optionally allow you
+to precede any filename by a commit, to specify a particular version
+of the file:
+
+-------------------------------------
+$ git diff v2.5:Makefile HEAD:Makefile.in
+-------------------------------------
+
+You can also use 'git-show' to see any such file:
+
+-------------------------------------
+$ git show v2.5:Makefile
+-------------------------------------
+
+Next Steps
+----------
+
+This tutorial should be enough to perform basic distributed revision
+control for your projects.  However, to fully understand the depth
+and power of git you need to understand two simple ideas on which it
+is based:
+
+  * The object database is the rather elegant system used to
+    store the history of your project--files, directories, and
+    commits.
+
+  * The index file is a cache of the state of a directory tree,
+    used to create commits, check out working directories, and
+    hold the various trees involved in a merge.
+
+Part two of this tutorial explains the object
+database, the index file, and a few other odds and ends that you'll
+need to make the most of git. You can find it at linkgit:gittutorial-2[7].
+
+If you don't want to continue with that right away, a few other
+digressions that may be interesting at this point are:
+
+  * linkgit:git-format-patch[1], linkgit:git-am[1]: These convert
+    series of git commits into emailed patches, and vice versa,
+    useful for projects such as the linux kernel which rely heavily
+    on emailed patches.
+
+  * linkgit:git-bisect[1]: When there is a regression in your
+    project, one way to track down the bug is by searching through
+    the history to find the exact commit that's to blame.  Git bisect
+    can help you perform a binary search for that commit.  It is
+    smart enough to perform a close-to-optimal search even in the
+    case of complex non-linear history with lots of merged branches.

+       have a locally checked-out copy of any of the files under

+       `repository.git` directory instead,
+       and no other files are present and checked out. Usually publishers of

+
+[[def_blob_object]]blob object::
+       Untyped <<def_object,object>>, e.g. the contents of a file.
+
+[[def_branch]]branch::
+       A "branch" is an active line of development.  The most recent
+       <<def_commit,commit>> on a branch is referred to as the tip of
+       that branch.  The tip of the branch is referenced by a branch
+       <<def_head,head>>, which moves forward as additional development
+       is done on the branch.  A single git
+       <<def_repository,repository>> can track an arbitrary number of
+       branches, but your <<def_working_tree,working tree>> is
+       associated with just one of them (the "current" or "checked out"
+       branch), and <<def_HEAD,HEAD>> points to that branch.
+
+[[def_cache]]cache::
+       Obsolete for: <<def_index,index>>.
+
+[[def_chain]]chain::
+       A list of objects, where each <<def_object,object>> in the list contains
+       a reference to its successor (for example, the successor of a
+       <<def_commit,commit>> could be one of its <<def_parent,parents>>).
+
+[[def_changeset]]changeset::
+       BitKeeper/cvsps speak for "<<def_commit,commit>>". Since git does not
+       store changes, but states, it really does not make sense to use the term
+       "changesets" with git.
+
+[[def_checkout]]checkout::
+       The action of updating all or part of the
+       <<def_working_tree,working tree>> with a <<def_tree_object,tree object>>
+       or <<def_blob_object,blob>> from the
+       <<def_object_database,object database>>, and updating the
+       <<def_index,index>> and <<def_HEAD,HEAD>> if the whole working tree has
+       been pointed at a new <<def_branch,branch>>.
+
+[[def_cherry-picking]]cherry-picking::
+       In <<def_SCM,SCM>> jargon, "cherry pick" means to choose a subset of
+       changes out of a series of changes (typically commits) and record them
+       as a new series of changes on top of a different codebase. In GIT, this is
+       performed by the "git cherry-pick" command to extract the change introduced
+       by an existing <<def_commit,commit>> and to record it based on the tip
+       of the current <<def_branch,branch>> as a new commit.
+
+[[def_clean]]clean::
+       A <<def_working_tree,working tree>> is clean, if it
+       corresponds to the <<def_revision,revision>> referenced by the current
+       <<def_head,head>>. Also see "<<def_dirty,dirty>>".
+
+[[def_commit]]commit::
+       As a noun: A single point in the
+       git history; the entire history of a project is represented as a
+       set of interrelated commits.  The word "commit" is often
+       used by git in the same places other revision control systems
+       use the words "revision" or "version".  Also used as a short
+       hand for <<def_commit_object,commit object>>.
++
+As a verb: The action of storing a new snapshot of the project's
+state in the git history, by creating a new commit representing the current
+state of the <<def_index,index>> and advancing <<def_HEAD,HEAD>>
+to point at the new commit.
+
+[[def_commit_object]]commit object::
+       An <<def_object,object>> which contains the information about a
+       particular <<def_revision,revision>>, such as <<def_parent,parents>>, committer,
+       author, date and the <<def_tree_object,tree object>> which corresponds
+       to the top <<def_directory,directory>> of the stored
+       revision.
+
+[[def_core_git]]core git::
+       Fundamental data structures and utilities of git. Exposes only limited
+       source code management tools.
+
+[[def_DAG]]DAG::
+       Directed acyclic graph. The <<def_commit_object,commit objects>> form a
+       directed acyclic graph, because they have parents (directed), and the
+       graph of commit objects is acyclic (there is no <<def_chain,chain>>
+       which begins and ends with the same <<def_object,object>>).
+
+[[def_dangling_object]]dangling object::
+       An <<def_unreachable_object,unreachable object>> which is not
+       <<def_reachable,reachable>> even from other unreachable objects; a
+       dangling object has no references to it from any
+       reference or <<def_object,object>> in the <<def_repository,repository>>.
+
+[[def_detached_HEAD]]detached HEAD::
+       Normally the <<def_HEAD,HEAD>> stores the name of a
+       <<def_branch,branch>>.  However, git also allows you to <<def_checkout,check out>>
+       an arbitrary <<def_commit,commit>> that isn't necessarily the tip of any
+       particular branch.  In this case HEAD is said to be "detached".
+

+       You are *waaaaay* behind. See <<def_index,index>>.
+
+[[def_directory]]directory::
+       The list you get with "ls" :-)
+
+[[def_dirty]]dirty::
+       A <<def_working_tree,working tree>> is said to be "dirty" if
+       it contains modifications which have not been <<def_commit,committed>> to the current
+       <<def_branch,branch>>.
+
+[[def_ent]]ent::
+       Favorite synonym to "<<def_tree-ish,tree-ish>>" by some total geeks. See
+       `http://en.wikipedia.org/wiki/Ent_(Middle-earth)` for an in-depth
+       explanation. Avoid this term, not to confuse people.
+
+[[def_evil_merge]]evil merge::
+       An evil merge is a <<def_merge,merge>> that introduces changes that
+       do not appear in any <<def_parent,parent>>.
+
+[[def_fast_forward]]fast forward::
+       A fast-forward is a special type of <<def_merge,merge>> where you have a
+       <<def_revision,revision>> and you are "merging" another
+       <<def_branch,branch>>'s changes that happen to be a descendant of what
+       you have. In such these cases, you do not make a new <<def_merge,merge>>
+       <<def_commit,commit>> but instead just update to his
+       revision. This will happen frequently on a
+       <<def_tracking_branch,tracking branch>> of a remote
+       <<def_repository,repository>>.
+
+[[def_fetch]]fetch::
+       Fetching a <<def_branch,branch>> means to get the
+       branch's <<def_head_ref,head ref>> from a remote
+       <<def_repository,repository>>, to find out which objects are
+       missing from the local <<def_object_database,object database>>,
+       and to get them, too.  See also linkgit:git-fetch[1].
+
+[[def_file_system]]file system::
+       Linus Torvalds originally designed git to be a user space file system,
+       i.e. the infrastructure to hold files and directories. That ensured the
+       efficiency and speed of git.
+
+[[def_git_archive]]git archive::
+       Synonym for <<def_repository,repository>> (for arch people).
+
+[[def_grafts]]grafts::
+       Grafts enables two otherwise different lines of development to be joined
+       together by recording fake ancestry information for commits. This way
+       you can make git pretend the set of <<def_parent,parents>> a <<def_commit,commit>> has
+       is different from what was recorded when the commit was
+       created. Configured via the `.git/info/grafts` file.
+
+[[def_hash]]hash::
+       In git's context, synonym to <<def_object_name,object name>>.
+
+[[def_head]]head::
+       A <<def_ref,named reference>> to the <<def_commit,commit>> at the tip of a
+       <<def_branch,branch>>.  Heads are stored in
+       `$GIT_DIR/refs/heads/`, except when using packed refs. (See
+       linkgit:git-pack-refs[1].)
+
+[[def_HEAD]]HEAD::
+       The current <<def_branch,branch>>.  In more detail: Your <<def_working_tree,
+       working tree>> is normally derived from the state of the tree
+       referred to by HEAD.  HEAD is a reference to one of the
+       <<def_head,heads>> in your repository, except when using a
+       <<def_detached_HEAD,detached HEAD>>, in which case it may
+       reference an arbitrary commit.
+
+[[def_head_ref]]head ref::
+       A synonym for <<def_head,head>>.
+
+[[def_hook]]hook::
+       During the normal execution of several git commands, call-outs are made
+       to optional scripts that allow a developer to add functionality or
+       checking. Typically, the hooks allow for a command to be pre-verified
+       and potentially aborted, and allow for a post-notification after the
+       operation is done. The hook scripts are found in the
+       `$GIT_DIR/hooks/` directory, and are enabled by simply
+       making them executable.
+
+[[def_index]]index::
+       A collection of files with stat information, whose contents are stored
+       as objects. The index is a stored version of your
+       <<def_working_tree,working tree>>. Truth be told, it can also contain a second, and even
+       a third version of a working tree, which are used
+       when <<def_merge,merging>>.
+
+[[def_index_entry]]index entry::
+       The information regarding a particular file, stored in the
+       <<def_index,index>>. An index entry can be unmerged, if a
+       <<def_merge,merge>> was started, but not yet finished (i.e. if
+       the index contains multiple versions of that file).
+
+[[def_master]]master::
+       The default development <<def_branch,branch>>. Whenever you
+       create a git <<def_repository,repository>>, a branch named
+       "master" is created, and becomes the active branch. In most
+       cases, this contains the local development, though that is
+       purely by convention and is not required.
+
+[[def_merge]]merge::
+       As a verb: To bring the contents of another
+       <<def_branch,branch>> (possibly from an external
+       <<def_repository,repository>>) into the current branch.  In the
+       case where the merged-in branch is from a different repository,
+       this is done by first <<def_fetch,fetching>> the remote branch
+       and then merging the result into the current branch.  This
+       combination of fetch and merge operations is called a
+       <<def_pull,pull>>.  Merging is performed by an automatic process
+       that identifies changes made since the branches diverged, and
+       then applies all those changes together.  In cases where changes
+       conflict, manual intervention may be required to complete the
+       merge.
++
+As a noun: unless it is a <<def_fast_forward,fast forward>>, a
+successful merge results in the creation of a new <<def_commit,commit>>
+representing the result of the merge, and having as
+<<def_parent,parents>> the tips of the merged <<def_branch,branches>>.
+This commit is referred to as a "merge commit", or sometimes just a
+"merge".
+
+[[def_object]]object::
+       The unit of storage in git. It is uniquely identified by the
+       <<def_SHA1,SHA1>> of its contents. Consequently, an
+       object can not be changed.
+
+[[def_object_database]]object database::
+       Stores a set of "objects", and an individual <<def_object,object>> is
+       identified by its <<def_object_name,object name>>. The objects usually
+       live in `$GIT_DIR/objects/`.
+
+[[def_object_identifier]]object identifier::
+       Synonym for <<def_object_name,object name>>.
+
+[[def_object_name]]object name::
+       The unique identifier of an <<def_object,object>>. The <<def_hash,hash>>
+       of the object's contents using the Secure Hash Algorithm
+       1 and usually represented by the 40 character hexadecimal encoding of
+       the <<def_hash,hash>> of the object.
+
+[[def_object_type]]object type::
+       One of the identifiers "<<def_commit_object,commit>>",
+       "<<def_tree_object,tree>>", "<<def_tag_object,tag>>" or
+       "<<def_blob_object,blob>>" describing the type of an
+       <<def_object,object>>.
+
+[[def_octopus]]octopus::
+       To <<def_merge,merge>> more than two <<def_branch,branches>>. Also denotes an
+       intelligent predator.
+
+[[def_origin]]origin::
+       The default upstream <<def_repository,repository>>. Most projects have
+       at least one upstream project which they track. By default
+       'origin' is used for that purpose. New upstream updates
+       will be fetched into remote <<def_tracking_branch,tracking branches>> named
+       origin/name-of-upstream-branch, which you can see using
+       "`git branch -r`".
+
+[[def_pack]]pack::
+       A set of objects which have been compressed into one file (to save space
+       or to transmit them efficiently).
+
+[[def_pack_index]]pack index::
+       The list of identifiers, and other information, of the objects in a
+       <<def_pack,pack>>, to assist in efficiently accessing the contents of a
+       pack.
+
+[[def_parent]]parent::
+       A <<def_commit_object,commit object>> contains a (possibly empty) list
+       of the logical predecessor(s) in the line of development, i.e. its
+       parents.
+
+[[def_pickaxe]]pickaxe::
+       The term <<def_pickaxe,pickaxe>> refers to an option to the diffcore
+       routines that help select changes that add or delete a given text
+       string. With the `--pickaxe-all` option, it can be used to view the full
+       <<def_changeset,changeset>> that introduced or removed, say, a
+       particular line of text. See linkgit:git-diff[1].
+
+[[def_plumbing]]plumbing::
+       Cute name for <<def_core_git,core git>>.
+
+[[def_porcelain]]porcelain::
+       Cute name for programs and program suites depending on
+       <<def_core_git,core git>>, presenting a high level access to
+       core git. Porcelains expose more of a <<def_SCM,SCM>>
+       interface than the <<def_plumbing,plumbing>>.
+
+[[def_pull]]pull::
+       Pulling a <<def_branch,branch>> means to <<def_fetch,fetch>> it and
+       <<def_merge,merge>> it.  See also linkgit:git-pull[1].
+
+[[def_push]]push::
+       Pushing a <<def_branch,branch>> means to get the branch's
+       <<def_head_ref,head ref>> from a remote <<def_repository,repository>>,
+       find out if it is a direct ancestor to the branch's local
+       head ref, and in that case, putting all
+       objects, which are <<def_reachable,reachable>> from the local
+       head ref, and which are missing from the remote
+       repository, into the remote
+       <<def_object_database,object database>>, and updating the remote
+       head ref. If the remote <<def_head,head>> is not an
+       ancestor to the local head, the push fails.
+
+[[def_reachable]]reachable::
+       All of the ancestors of a given <<def_commit,commit>> are said to be
+       "reachable" from that commit. More
+       generally, one <<def_object,object>> is reachable from
+       another if we can reach the one from the other by a <<def_chain,chain>>
+       that follows <<def_tag,tags>> to whatever they tag,
+       <<def_commit_object,commits>> to their parents or trees, and
+       <<def_tree_object,trees>> to the trees or <<def_blob_object,blobs>>
+       that they contain.
+
+[[def_rebase]]rebase::
+       To reapply a series of changes from a <<def_branch,branch>> to a
+       different base, and reset the <<def_head,head>> of that branch
+       to the result.
+
+[[def_ref]]ref::
+       A 40-byte hex representation of a <<def_SHA1,SHA1>> or a name that
+       denotes a particular <<def_object,object>>. These may be stored in
+       `$GIT_DIR/refs/`.
+
+[[def_reflog]]reflog::
+       A reflog shows the local "history" of a ref.  In other words,
+       it can tell you what the 3rd last revision in _this_ repository
+       was, and what was the current state in _this_ repository,
+       yesterday 9:14pm.  See linkgit:git-reflog[1] for details.
+
+[[def_refspec]]refspec::
+       A "refspec" is used by <<def_fetch,fetch>> and
+       <<def_push,push>> to describe the mapping between remote
+       <<def_ref,ref>> and local ref. They are combined with a colon in
+       the format <src>:<dst>, preceded by an optional plus sign, +.
+       For example: `git fetch $URL
+       refs/heads/master:refs/heads/origin` means "grab the master
+       <<def_branch,branch>> <<def_head,head>> from the $URL and store
+       it as my origin branch head". And `git push
+       $URL refs/heads/master:refs/heads/to-upstream` means "publish my
+       master branch head as to-upstream branch at $URL". See also
+       linkgit:git-push[1].
+
+[[def_repository]]repository::
+       A collection of <<def_ref,refs>> together with an
+       <<def_object_database,object database>> containing all objects
+       which are <<def_reachable,reachable>> from the refs, possibly
+       accompanied by meta data from one or more <<def_porcelain,porcelains>>. A
+       repository can share an object database with other repositories
+       via <<def_alternate_object_database,alternates mechanism>>.
+
+[[def_resolve]]resolve::
+       The action of fixing up manually what a failed automatic
+       <<def_merge,merge>> left behind.
+
+[[def_revision]]revision::
+       A particular state of files and directories which was stored in the
+       <<def_object_database,object database>>. It is referenced by a
+       <<def_commit_object,commit object>>.
+
+[[def_rewind]]rewind::
+       To throw away part of the development, i.e. to assign the
+       <<def_head,head>> to an earlier <<def_revision,revision>>.
+
+[[def_SCM]]SCM::
+       Source code management (tool).
+
+[[def_SHA1]]SHA1::
+       Synonym for <<def_object_name,object name>>.
+
+[[def_shallow_repository]]shallow repository::
+       A shallow <<def_repository,repository>> has an incomplete
+       history some of whose <<def_commit,commits>> have <<def_parent,parents>> cauterized away (in other
+       words, git is told to pretend that these commits do not have the
+       parents, even though they are recorded in the <<def_commit_object,commit
+       object>>). This is sometimes useful when you are interested only in the
+       recent history of a project even though the real history recorded in the
+       upstream is much larger. A shallow repository
+       is created by giving the `--depth` option to linkgit:git-clone[1], and
+       its history can be later deepened with linkgit:git-fetch[1].
+
+[[def_symref]]symref::
+       Symbolic reference: instead of containing the <<def_SHA1,SHA1>>
+       id itself, it is of the format 'ref: refs/some/thing' and when
+       referenced, it recursively dereferences to this reference.
+       '<<def_HEAD,HEAD>>' is a prime example of a symref. Symbolic
+       references are manipulated with the linkgit:git-symbolic-ref[1]
+       command.
+
+[[def_tag]]tag::
+       A <<def_ref,ref>> pointing to a <<def_tag_object,tag>> or
+       <<def_commit_object,commit object>>. In contrast to a <<def_head,head>>,
+       a tag is not changed by a <<def_commit,commit>>. Tags (not
+       <<def_tag_object,tag objects>>) are stored in `$GIT_DIR/refs/tags/`. A
+       git tag has nothing to do with a Lisp tag (which would be
+       called an <<def_object_type,object type>> in git's context). A
+       tag is most typically used to mark a particular point in the
+       commit ancestry <<def_chain,chain>>.
+
+[[def_tag_object]]tag object::
+       An <<def_object,object>> containing a <<def_ref,ref>> pointing to
+       another object, which can contain a message just like a
+       <<def_commit_object,commit object>>. It can also contain a (PGP)
+       signature, in which case it is called a "signed tag object".
+
+[[def_topic_branch]]topic branch::
+       A regular git <<def_branch,branch>> that is used by a developer to
+       identify a conceptual line of development. Since branches are very easy
+       and inexpensive, it is often desirable to have several small branches
+       that each contain very well defined concepts or small incremental yet
+       related changes.
+
+[[def_tracking_branch]]tracking branch::
+       A regular git <<def_branch,branch>> that is used to follow changes from
+       another <<def_repository,repository>>. A tracking
+       branch should not contain direct modifications or have local commits
+       made to it. A tracking branch can usually be
+       identified as the right-hand-side <<def_ref,ref>> in a Pull:
+       <<def_refspec,refspec>>.
+
+[[def_tree]]tree::
+       Either a <<def_working_tree,working tree>>, or a <<def_tree_object,tree
+       object>> together with the dependent <<def_blob_object,blob>> and tree objects
+       (i.e. a stored representation of a working tree).
+
+[[def_tree_object]]tree object::
+       An <<def_object,object>> containing a list of file names and modes along
+       with refs to the associated blob and/or tree objects. A
+       <<def_tree,tree>> is equivalent to a <<def_directory,directory>>.
+
+[[def_tree-ish]]tree-ish::
+       A <<def_ref,ref>> pointing to either a <<def_commit_object,commit
+       object>>, a <<def_tree_object,tree object>>, or a <<def_tag_object,tag
+       object>> pointing to a tag or commit or tree object.
+
+[[def_unmerged_index]]unmerged index::
+       An <<def_index,index>> which contains unmerged
+       <<def_index_entry,index entries>>.
+
+[[def_unreachable_object]]unreachable object::
+       An <<def_object,object>> which is not <<def_reachable,reachable>> from a
+       <<def_branch,branch>>, <<def_tag,tag>>, or any other reference.
+
+[[def_working_tree]]working tree::
+       The tree of actual checked out files.  The working tree is
+       normally equal to the <<def_HEAD,HEAD>> plus any local changes
+       that you have made but not yet committed.

-GIT Glossary
-============
-
-[[def_alternate_object_database]]alternate object database::
-       Via the alternates mechanism, a <<def_repository,repository>>
-       can inherit part of its <<def_object_database,object database>>
-       from another object database, which is called "alternate".
-
-[[def_bare_repository]]bare repository::
-       A bare repository is normally an appropriately
-       named <<def_directory,directory>> with a `.git` suffix that does not
-       have a locally checked-out copy of any of the files under
-       revision control. That is, all of the `git`
-       administrative and control files that would normally be present in the
-       hidden `.git` sub-directory are directly present in the
-       `repository.git` directory instead,
-       and no other files are present and checked out. Usually publishers of
-       public repositories make bare repositories available.
-
-[[def_blob_object]]blob object::
-       Untyped <<def_object,object>>, e.g. the contents of a file.
-
-[[def_branch]]branch::
-       A "branch" is an active line of development.  The most recent
-       <<def_commit,commit>> on a branch is referred to as the tip of
-       that branch.  The tip of the branch is referenced by a branch
-       <<def_head,head>>, which moves forward as additional development
-       is done on the branch.  A single git
-       <<def_repository,repository>> can track an arbitrary number of
-       branches, but your <<def_working_tree,working tree>> is
-       associated with just one of them (the "current" or "checked out"
-       branch), and <<def_HEAD,HEAD>> points to that branch.
-
-[[def_cache]]cache::
-       Obsolete for: <<def_index,index>>.
-
-[[def_chain]]chain::
-       A list of objects, where each <<def_object,object>> in the list contains
-       a reference to its successor (for example, the successor of a
-       <<def_commit,commit>> could be one of its <<def_parent,parents>>).
-
-[[def_changeset]]changeset::
-       BitKeeper/cvsps speak for "<<def_commit,commit>>". Since git does not
-       store changes, but states, it really does not make sense to use the term
-       "changesets" with git.
-
-[[def_checkout]]checkout::
-       The action of updating the <<def_working_tree,working tree>> to a
-       <<def_revision,revision>> which was stored in the
-       <<def_object_database,object database>>.
-
-[[def_cherry-picking]]cherry-picking::
-       In <<def_SCM,SCM>> jargon, "cherry pick" means to choose a subset of
-       changes out of a series of changes (typically commits) and record them
-       as a new series of changes on top of a different codebase. In GIT, this is
-       performed by the "git cherry-pick" command to extract the change introduced
-       by an existing <<def_commit,commit>> and to record it based on the tip
-       of the current <<def_branch,branch>> as a new commit.
-
-[[def_clean]]clean::
-       A <<def_working_tree,working tree>> is clean, if it
-       corresponds to the <<def_revision,revision>> referenced by the current
-       <<def_head,head>>. Also see "<<def_dirty,dirty>>".
-
-[[def_commit]]commit::
-       As a noun: A single point in the
-       git history; the entire history of a project is represented as a
-       set of interrelated commits.  The word "commit" is often
-       used by git in the same places other revision control systems
-       use the words "revision" or "version".  Also used as a short
-       hand for <<def_commit_object,commit object>>.
-+
-As a verb: The action of storing a new snapshot of the project's
-state in the git history, by creating a new commit representing the current
-state of the <<def_index,index>> and advancing <<def_HEAD,HEAD>>
-to point at the new commit.
-
-[[def_commit_object]]commit object::
-       An <<def_object,object>> which contains the information about a
-       particular <<def_revision,revision>>, such as <<def_parent,parents>>, committer,
-       author, date and the <<def_tree_object,tree object>> which corresponds
-       to the top <<def_directory,directory>> of the stored
-       revision.
-
-[[def_core_git]]core git::
-       Fundamental data structures and utilities of git. Exposes only limited
-       source code management tools.
-
-[[def_DAG]]DAG::
-       Directed acyclic graph. The <<def_commit,commit>> objects form a
-       directed acyclic graph, because they have parents (directed), and the
-       graph of commit objects is acyclic (there is no
-       <<def_chain,chain>> which begins and ends with the same
-       <<def_object,object>>).
-
-[[def_dangling_object]]dangling object::
-       An <<def_unreachable_object,unreachable object>> which is not
-       <<def_reachable,reachable>> even from other unreachable objects; a
-       dangling object has no references to it from any
-       reference or <<def_object,object>> in the <<def_repository,repository>>.
-
-[[def_detached_HEAD]]detached HEAD::
-       Normally the <<def_HEAD,HEAD>> stores the name of a
-       <<def_branch,branch>>.  However, git also allows you to <<def_checkout,check out>>
-       an arbitrary <<def_commit,commit>> that isn't necessarily the tip of any
-       particular branch.  In this case HEAD is said to be "detached".
-
-[[def_dircache]]dircache::
-       You are *waaaaay* behind. See <<def_index,index>>.
-
-[[def_directory]]directory::
-       The list you get with "ls" :-)
-
-[[def_dirty]]dirty::
-       A <<def_working_tree,working tree>> is said to be "dirty" if
-       it contains modifications which have not been <<def_commit,committed>> to the current
-       <<def_branch,branch>>.
-
-[[def_ent]]ent::
-       Favorite synonym to "<<def_tree-ish,tree-ish>>" by some total geeks. See
-       `http://en.wikipedia.org/wiki/Ent_(Middle-earth)` for an in-depth
-       explanation. Avoid this term, not to confuse people.
-
-[[def_evil_merge]]evil merge::
-       An evil merge is a <<def_merge,merge>> that introduces changes that
-       do not appear in any <<def_parent,parent>>.
-
-[[def_fast_forward]]fast forward::
-       A fast-forward is a special type of <<def_merge,merge>> where you have a
-       <<def_revision,revision>> and you are "merging" another
-       <<def_branch,branch>>'s changes that happen to be a descendant of what
-       you have. In such these cases, you do not make a new <<def_merge,merge>>
-       <<def_commit,commit>> but instead just update to his
-       revision. This will happen frequently on a
-       <<def_tracking_branch,tracking branch>> of a remote
-       <<def_repository,repository>>.
-
-[[def_fetch]]fetch::
-       Fetching a <<def_branch,branch>> means to get the
-       branch's <<def_head_ref,head ref>> from a remote
-       <<def_repository,repository>>, to find out which objects are
-       missing from the local <<def_object_database,object database>>,
-       and to get them, too.  See also linkgit:git-fetch[1].
-
-[[def_file_system]]file system::
-       Linus Torvalds originally designed git to be a user space file system,
-       i.e. the infrastructure to hold files and directories. That ensured the
-       efficiency and speed of git.
-
-[[def_git_archive]]git archive::
-       Synonym for <<def_repository,repository>> (for arch people).
-
-[[def_grafts]]grafts::
-       Grafts enables two otherwise different lines of development to be joined
-       together by recording fake ancestry information for commits. This way
-       you can make git pretend the set of <<def_parent,parents>> a <<def_commit,commit>> has
-       is different from what was recorded when the commit was
-       created. Configured via the `.git/info/grafts` file.
-
-[[def_hash]]hash::
-       In git's context, synonym to <<def_object_name,object name>>.
-
-[[def_head]]head::
-       A <<def_ref,named reference>> to the <<def_commit,commit>> at the tip of a
-       <<def_branch,branch>>.  Heads are stored in
-       `$GIT_DIR/refs/heads/`, except when using packed refs. (See
-       linkgit:git-pack-refs[1].)
-
-[[def_HEAD]]HEAD::
-       The current <<def_branch,branch>>.  In more detail: Your <<def_working_tree,
-       working tree>> is normally derived from the state of the tree
-       referred to by HEAD.  HEAD is a reference to one of the
-       <<def_head,heads>> in your repository, except when using a
-       <<def_detached_HEAD,detached HEAD>>, in which case it may
-       reference an arbitrary commit.
-
-[[def_head_ref]]head ref::
-       A synonym for <<def_head,head>>.
-
-[[def_hook]]hook::
-       During the normal execution of several git commands, call-outs are made
-       to optional scripts that allow a developer to add functionality or
-       checking. Typically, the hooks allow for a command to be pre-verified
-       and potentially aborted, and allow for a post-notification after the
-       operation is done. The hook scripts are found in the
-       `$GIT_DIR/hooks/` directory, and are enabled by simply
-       making them executable.
-
-[[def_index]]index::
-       A collection of files with stat information, whose contents are stored
-       as objects. The index is a stored version of your
-       <<def_working_tree,working tree>>. Truth be told, it can also contain a second, and even
-       a third version of a working tree, which are used
-       when <<def_merge,merging>>.
-
-[[def_index_entry]]index entry::
-       The information regarding a particular file, stored in the
-       <<def_index,index>>. An index entry can be unmerged, if a
-       <<def_merge,merge>> was started, but not yet finished (i.e. if
-       the index contains multiple versions of that file).
-
-[[def_master]]master::
-       The default development <<def_branch,branch>>. Whenever you
-       create a git <<def_repository,repository>>, a branch named
-       "master" is created, and becomes the active branch. In most
-       cases, this contains the local development, though that is
-       purely by convention and is not required.
-
-[[def_merge]]merge::
-       As a verb: To bring the contents of another
-       <<def_branch,branch>> (possibly from an external
-       <<def_repository,repository>>) into the current branch.  In the
-       case where the merged-in branch is from a different repository,
-       this is done by first <<def_fetch,fetching>> the remote branch
-       and then merging the result into the current branch.  This
-       combination of fetch and merge operations is called a
-       <<def_pull,pull>>.  Merging is performed by an automatic process
-       that identifies changes made since the branches diverged, and
-       then applies all those changes together.  In cases where changes
-       conflict, manual intervention may be required to complete the
-       merge.
-+
-As a noun: unless it is a <<def_fast_forward,fast forward>>, a
-successful merge results in the creation of a new <<def_commit,commit>>
-representing the result of the merge, and having as
-<<def_parent,parents>> the tips of the merged <<def_branch,branches>>.
-This commit is referred to as a "merge commit", or sometimes just a
-"merge".
-
-[[def_object]]object::
-       The unit of storage in git. It is uniquely identified by the
-       <<def_SHA1,SHA1>> of its contents. Consequently, an
-       object can not be changed.
-
-[[def_object_database]]object database::
-       Stores a set of "objects", and an individual <<def_object,object>> is
-       identified by its <<def_object_name,object name>>. The objects usually
-       live in `$GIT_DIR/objects/`.
-
-[[def_object_identifier]]object identifier::
-       Synonym for <<def_object_name,object name>>.
-
-[[def_object_name]]object name::
-       The unique identifier of an <<def_object,object>>. The <<def_hash,hash>>
-       of the object's contents using the Secure Hash Algorithm
-       1 and usually represented by the 40 character hexadecimal encoding of
-       the <<def_hash,hash>> of the object.
-
-[[def_object_type]]object type::
-       One of the identifiers
-       "<<def_commit,commit>>","<<def_tree,tree>>","<<def_tag,tag>>" or "<<def_blob_object,blob>>"
-       describing the type of an <<def_object,object>>.
-
-[[def_octopus]]octopus::
-       To <<def_merge,merge>> more than two <<def_branch,branches>>. Also denotes an
-       intelligent predator.
-
-[[def_origin]]origin::
-       The default upstream <<def_repository,repository>>. Most projects have
-       at least one upstream project which they track. By default
-       'origin' is used for that purpose. New upstream updates
-       will be fetched into remote <<def_tracking_branch,tracking branches>> named
-       origin/name-of-upstream-branch, which you can see using
-       "`git branch -r`".
-
-[[def_pack]]pack::
-       A set of objects which have been compressed into one file (to save space
-       or to transmit them efficiently).
-
-[[def_pack_index]]pack index::
-       The list of identifiers, and other information, of the objects in a
-       <<def_pack,pack>>, to assist in efficiently accessing the contents of a
-       pack.
-
-[[def_parent]]parent::
-       A <<def_commit_object,commit object>> contains a (possibly empty) list
-       of the logical predecessor(s) in the line of development, i.e. its
-       parents.
-
-[[def_pickaxe]]pickaxe::
-       The term <<def_pickaxe,pickaxe>> refers to an option to the diffcore
-       routines that help select changes that add or delete a given text
-       string. With the `--pickaxe-all` option, it can be used to view the full
-       <<def_changeset,changeset>> that introduced or removed, say, a
-       particular line of text. See linkgit:git-diff[1].
-
-[[def_plumbing]]plumbing::
-       Cute name for <<def_core_git,core git>>.
-
-[[def_porcelain]]porcelain::
-       Cute name for programs and program suites depending on
-       <<def_core_git,core git>>, presenting a high level access to
-       core git. Porcelains expose more of a <<def_SCM,SCM>>
-       interface than the <<def_plumbing,plumbing>>.
-
-[[def_pull]]pull::
-       Pulling a <<def_branch,branch>> means to <<def_fetch,fetch>> it and
-       <<def_merge,merge>> it.  See also linkgit:git-pull[1].
-
-[[def_push]]push::
-       Pushing a <<def_branch,branch>> means to get the branch's
-       <<def_head_ref,head ref>> from a remote <<def_repository,repository>>,
-       find out if it is a direct ancestor to the branch's local
-       head ref, and in that case, putting all
-       objects, which are <<def_reachable,reachable>> from the local
-       head ref, and which are missing from the remote
-       repository, into the remote
-       <<def_object_database,object database>>, and updating the remote
-       head ref. If the remote <<def_head,head>> is not an
-       ancestor to the local head, the push fails.
-
-[[def_reachable]]reachable::
-       All of the ancestors of a given <<def_commit,commit>> are said to be
-       "reachable" from that commit. More
-       generally, one <<def_object,object>> is reachable from
-       another if we can reach the one from the other by a <<def_chain,chain>>
-       that follows <<def_tag,tags>> to whatever they tag,
-       <<def_commit_object,commits>> to their parents or trees, and
-       <<def_tree_object,trees>> to the trees or <<def_blob_object,blobs>>
-       that they contain.
-
-[[def_rebase]]rebase::
-       To reapply a series of changes from a <<def_branch,branch>> to a
-       different base, and reset the <<def_head,head>> of that branch
-       to the result.
-
-[[def_ref]]ref::
-       A 40-byte hex representation of a <<def_SHA1,SHA1>> or a name that
-       denotes a particular <<def_object,object>>. These may be stored in
-       `$GIT_DIR/refs/`.
-
-[[def_reflog]]reflog::
-       A reflog shows the local "history" of a ref.  In other words,
-       it can tell you what the 3rd last revision in _this_ repository
-       was, and what was the current state in _this_ repository,
-       yesterday 9:14pm.  See linkgit:git-reflog[1] for details.
-
-[[def_refspec]]refspec::
-       A "refspec" is used by <<def_fetch,fetch>> and
-       <<def_push,push>> to describe the mapping between remote
-       <<def_ref,ref>> and local ref. They are combined with a colon in
-       the format <src>:<dst>, preceded by an optional plus sign, +.
-       For example: `git fetch $URL
-       refs/heads/master:refs/heads/origin` means "grab the master
-       <<def_branch,branch>> <<def_head,head>> from the $URL and store
-       it as my origin branch head". And `git push
-       $URL refs/heads/master:refs/heads/to-upstream` means "publish my
-       master branch head as to-upstream branch at $URL". See also
-       linkgit:git-push[1].
-
-[[def_repository]]repository::
-       A collection of <<def_ref,refs>> together with an
-       <<def_object_database,object database>> containing all objects
-       which are <<def_reachable,reachable>> from the refs, possibly
-       accompanied by meta data from one or more <<def_porcelain,porcelains>>. A
-       repository can share an object database with other repositories
-       via <<def_alternate_object_database,alternates mechanism>>.
-
-[[def_resolve]]resolve::
-       The action of fixing up manually what a failed automatic
-       <<def_merge,merge>> left behind.
-
-[[def_revision]]revision::
-       A particular state of files and directories which was stored in the
-       <<def_object_database,object database>>. It is referenced by a
-       <<def_commit_object,commit object>>.
-
-[[def_rewind]]rewind::
-       To throw away part of the development, i.e. to assign the
-       <<def_head,head>> to an earlier <<def_revision,revision>>.
-
-[[def_SCM]]SCM::
-       Source code management (tool).
-
-[[def_SHA1]]SHA1::
-       Synonym for <<def_object_name,object name>>.
-
-[[def_shallow_repository]]shallow repository::
-       A shallow <<def_repository,repository>> has an incomplete
-       history some of whose <<def_commit,commits>> have <<def_parent,parents>> cauterized away (in other
-       words, git is told to pretend that these commits do not have the
-       parents, even though they are recorded in the <<def_commit_object,commit
-       object>>). This is sometimes useful when you are interested only in the
-       recent history of a project even though the real history recorded in the
-       upstream is much larger. A shallow repository
-       is created by giving the `--depth` option to linkgit:git-clone[1], and
-       its history can be later deepened with linkgit:git-fetch[1].
-
-[[def_symref]]symref::
-       Symbolic reference: instead of containing the <<def_SHA1,SHA1>>
-       id itself, it is of the format 'ref: refs/some/thing' and when
-       referenced, it recursively dereferences to this reference.
-       '<<def_HEAD,HEAD>>' is a prime example of a symref. Symbolic
-       references are manipulated with the linkgit:git-symbolic-ref[1]
-       command.
-
-[[def_tag]]tag::
-       A <<def_ref,ref>> pointing to a <<def_tag_object,tag>> or
-       <<def_commit_object,commit object>>. In contrast to a <<def_head,head>>,
-       a tag is not changed by a <<def_commit,commit>>. Tags (not
-       <<def_tag_object,tag objects>>) are stored in `$GIT_DIR/refs/tags/`. A
-       git tag has nothing to do with a Lisp tag (which would be
-       called an <<def_object_type,object type>> in git's context). A
-       tag is most typically used to mark a particular point in the
-       commit ancestry <<def_chain,chain>>.
-
-[[def_tag_object]]tag object::
-       An <<def_object,object>> containing a <<def_ref,ref>> pointing to
-       another object, which can contain a message just like a
-       <<def_commit_object,commit object>>. It can also contain a (PGP)
-       signature, in which case it is called a "signed tag object".
-
-[[def_topic_branch]]topic branch::
-       A regular git <<def_branch,branch>> that is used by a developer to
-       identify a conceptual line of development. Since branches are very easy
-       and inexpensive, it is often desirable to have several small branches
-       that each contain very well defined concepts or small incremental yet
-       related changes.
-
-[[def_tracking_branch]]tracking branch::
-       A regular git <<def_branch,branch>> that is used to follow changes from
-       another <<def_repository,repository>>. A tracking
-       branch should not contain direct modifications or have local commits
-       made to it. A tracking branch can usually be
-       identified as the right-hand-side <<def_ref,ref>> in a Pull:
-       <<def_refspec,refspec>>.
-
-[[def_tree]]tree::
-       Either a <<def_working_tree,working tree>>, or a <<def_tree_object,tree
-       object>> together with the dependent <<def_blob_object,blob>> and tree objects
-       (i.e. a stored representation of a working tree).
-
-[[def_tree_object]]tree object::
-       An <<def_object,object>> containing a list of file names and modes along
-       with refs to the associated blob and/or tree objects. A
-       <<def_tree,tree>> is equivalent to a <<def_directory,directory>>.
-
-[[def_tree-ish]]tree-ish::
-       A <<def_ref,ref>> pointing to either a <<def_commit_object,commit
-       object>>, a <<def_tree_object,tree object>>, or a <<def_tag_object,tag
-       object>> pointing to a tag or commit or tree object.
-
-[[def_unmerged_index]]unmerged index::
-       An <<def_index,index>> which contains unmerged
-       <<def_index_entry,index entries>>.
-
-[[def_unreachable_object]]unreachable object::
-       An <<def_object,object>> which is not <<def_reachable,reachable>> from a
-       <<def_branch,branch>>, <<def_tag,tag>>, or any other reference.
-
-[[def_working_tree]]working tree::
-       The tree of actual checked out files.  The working tree is
-       normally equal to the <<def_HEAD,HEAD>> plus any local changes
-       that you have made but not yet committed.

-Hooks used by git
-=================
-
-Hooks are little scripts you can place in `$GIT_DIR/hooks`
-directory to trigger action at certain points.  When
-`git-init` is run, a handful example hooks are copied in the
-`hooks` directory of the new repository, but by default they are
-all disabled.  To enable a hook, make it executable with `chmod +x`.
-
-This document describes the currently defined hooks.
-
-applypatch-msg
---------------
-
-This hook is invoked by `git-am` script.  It takes a single
-parameter, the name of the file that holds the proposed commit
-log message.  Exiting with non-zero status causes
-`git-am` to abort before applying the patch.
-
-The hook is allowed to edit the message file in place, and can
-be used to normalize the message into some project standard
-format (if the project has one). It can also be used to refuse
-the commit after inspecting the message file.
-
-The default 'applypatch-msg' hook, when enabled, runs the
-'commit-msg' hook, if the latter is enabled.
-
-pre-applypatch
---------------
-
-This hook is invoked by `git-am`.  It takes no parameter,
-and is invoked after the patch is applied, but before a commit
-is made.  Exiting with non-zero status causes the working tree
-after application of the patch not committed.
-
-It can be used to inspect the current working tree and refuse to
-make a commit if it does not pass certain test.
-
-The default 'pre-applypatch' hook, when enabled, runs the
-'pre-commit' hook, if the latter is enabled.
-
-post-applypatch
----------------
-
-This hook is invoked by `git-am`.  It takes no parameter,
-and is invoked after the patch is applied and a commit is made.
-
-This hook is meant primarily for notification, and cannot affect
-the outcome of `git-am`.
-
-pre-commit
-----------
-
-This hook is invoked by `git-commit`, and can be bypassed
-with `\--no-verify` option.  It takes no parameter, and is
-invoked before obtaining the proposed commit log message and
-making a commit.  Exiting with non-zero status from this script
-causes the `git-commit` to abort.
-
-The default 'pre-commit' hook, when enabled, catches introduction
-of lines with trailing whitespaces and aborts the commit when
-such a line is found.
-
-commit-msg
-----------
-
-This hook is invoked by `git-commit`, and can be bypassed
-with `\--no-verify` option.  It takes a single parameter, the
-name of the file that holds the proposed commit log message.
-Exiting with non-zero status causes the `git-commit` to
-abort.
-
-The hook is allowed to edit the message file in place, and can
-be used to normalize the message into some project standard
-format (if the project has one). It can also be used to refuse
-the commit after inspecting the message file.
-
-The default 'commit-msg' hook, when enabled, detects duplicate
-"Signed-off-by" lines, and aborts the commit if one is found.
-
-post-commit
------------
-
-This hook is invoked by `git-commit`.  It takes no
-parameter, and is invoked after a commit is made.
-
-This hook is meant primarily for notification, and cannot affect
-the outcome of `git-commit`.
-
-post-checkout
------------
-
-This hook is invoked when a `git-checkout` is run after having updated the
-worktree.  The hook is given three parameters: the ref of the previous HEAD,
-the ref of the new HEAD (which may or may not have changed), and a flag
-indicating whether the checkout was a branch checkout (changing branches,
-flag=1) or a file checkout (retrieving a file from the index, flag=0).
-This hook cannot affect the outcome of `git-checkout`.
-
-This hook can be used to perform repository validity checks, auto-display
-differences from the previous HEAD if different, or set working dir metadata
-properties.
-
-post-merge
------------
-
-This hook is invoked by `git-merge`, which happens when a `git pull`
-is done on a local repository.  The hook takes a single parameter, a status
-flag specifying whether or not the merge being done was a squash merge.
-This hook cannot affect the outcome of `git-merge`.
-
-This hook can be used in conjunction with a corresponding pre-commit hook to
-save and restore any form of metadata associated with the working tree
-(eg: permissions/ownership, ACLS, etc).  See contrib/hooks/setgitperms.perl
-for an example of how to do this.
-
-[[pre-receive]]
-pre-receive
------------
-
-This hook is invoked by `git-receive-pack` on the remote repository,
-which happens when a `git push` is done on a local repository.
-Just before starting to update refs on the remote repository, the
-pre-receive hook is invoked.  Its exit status determines the success
-or failure of the update.
-
-This hook executes once for the receive operation. It takes no
-arguments, but for each ref to be updated it receives on standard
-input a line of the format:
-
-  <old-value> SP <new-value> SP <ref-name> LF
-
-where `<old-value>` is the old object name stored in the ref,
-`<new-value>` is the new object name to be stored in the ref and
-`<ref-name>` is the full name of the ref.
-When creating a new ref, `<old-value>` is 40 `0`.
-
-If the hook exits with non-zero status, none of the refs will be
-updated. If the hook exits with zero, updating of individual refs can
-still be prevented by the <<update,'update'>> hook.
-
-Both standard output and standard error output are forwarded to
-`git-send-pack` on the other end, so you can simply `echo` messages
-for the user.
-
-[[update]]
-update
-------
-
-This hook is invoked by `git-receive-pack` on the remote repository,
-which happens when a `git push` is done on a local repository.
-Just before updating the ref on the remote repository, the update hook
-is invoked.  Its exit status determines the success or failure of
-the ref update.
-
-The hook executes once for each ref to be updated, and takes
-three parameters:
-
- - the name of the ref being updated,
- - the old object name stored in the ref,
- - and the new objectname to be stored in the ref.
-
-A zero exit from the update hook allows the ref to be updated.
-Exiting with a non-zero status prevents `git-receive-pack`
-from updating that ref.
-
-This hook can be used to prevent 'forced' update on certain refs by
-making sure that the object name is a commit object that is a
-descendant of the commit object named by the old object name.
-That is, to enforce a "fast forward only" policy.
-
-It could also be used to log the old..new status.  However, it
-does not know the entire set of branches, so it would end up
-firing one e-mail per ref when used naively, though.  The
-<<post-receive,'post-receive'>> hook is more suited to that.
-
-Another use suggested on the mailing list is to use this hook to
-implement access control which is finer grained than the one
-based on filesystem group.
-
-Both standard output and standard error output are forwarded to
-`git-send-pack` on the other end, so you can simply `echo` messages
-for the user.
-
-The default 'update' hook, when enabled--and with
-`hooks.allowunannotated` config option turned on--prevents
-unannotated tags to be pushed.
-
-[[post-receive]]
-post-receive
-------------
-
-This hook is invoked by `git-receive-pack` on the remote repository,
-which happens when a `git push` is done on a local repository.
-It executes on the remote repository once after all the refs have
-been updated.
-
-This hook executes once for the receive operation.  It takes no
-arguments, but gets the same information as the
-<<pre-receive,'pre-receive'>>
-hook does on its standard input.
-
-This hook does not affect the outcome of `git-receive-pack`, as it
-is called after the real work is done.
-
-This supersedes the <<post-update,'post-update'>> hook in that it gets
-both old and new values of all the refs in addition to their
-names.
-
-Both standard output and standard error output are forwarded to
-`git-send-pack` on the other end, so you can simply `echo` messages
-for the user.
-
-The default 'post-receive' hook is empty, but there is
-a sample script `post-receive-email` provided in the `contrib/hooks`
-directory in git distribution, which implements sending commit
-emails.
-
-[[post-update]]
-post-update
------------
-
-This hook is invoked by `git-receive-pack` on the remote repository,
-which happens when a `git push` is done on a local repository.
-It executes on the remote repository once after all the refs have
-been updated.
-
-It takes a variable number of parameters, each of which is the
-name of ref that was actually updated.
-
-This hook is meant primarily for notification, and cannot affect
-the outcome of `git-receive-pack`.
-
-The 'post-update' hook can tell what are the heads that were pushed,
-but it does not know what their original and updated values are,
-so it is a poor place to do log old..new. The
-<<post-receive,'post-receive'>> hook does get both original and
-updated values of the refs. You might consider it instead if you need
-them.
-
-When enabled, the default 'post-update' hook runs
-`git-update-server-info` to keep the information used by dumb
-transports (e.g., HTTP) up-to-date.  If you are publishing
-a git repository that is accessible via HTTP, you should
-probably enable this hook.
-
-Both standard output and standard error output are forwarded to

-git repository layout
-=====================
-
-You may find these things in your git repository (`.git`
-directory for a repository associated with your working tree, or
-`'project'.git` directory for a public 'bare' repository).
-
-objects::
-       Object store associated with this repository.  Usually
-       an object store is self sufficient (i.e. all the objects
-       that are referred to by an object found in it are also
-       found in it), but there are couple of ways to violate
-       it.
-+
-. You could populate the repository by running a commit walker
-without `-a` option.  Depending on which options are given, you
-could have only commit objects without associated blobs and
-trees this way, for example.  A repository with this kind of
-incomplete object store is not suitable to be published to the
-outside world but sometimes useful for private repository.
-. You also could have an incomplete but locally usable repository
-by cloning shallowly.  See linkgit:git-clone[1].
-. You can be using `objects/info/alternates` mechanism, or
-`$GIT_ALTERNATE_OBJECT_DIRECTORIES` mechanism to 'borrow'
-objects from other object stores.  A repository with this kind
-of incomplete object store is not suitable to be published for
-use with dumb transports but otherwise is OK as long as
-`objects/info/alternates` points at the right object stores
-it borrows from.
-
-objects/[0-9a-f][0-9a-f]::
-       Traditionally, each object is stored in its own file.
-       They are split into 256 subdirectories using the first
-       two letters from its object name to keep the number of
-       directory entries `objects` directory itself needs to
-       hold.  Objects found here are often called 'unpacked'
-       (or 'loose') objects.
-
-objects/pack::
-       Packs (files that store many object in compressed form,
-       along with index files to allow them to be randomly
-       accessed) are found in this directory.
-
-objects/info::
-       Additional information about the object store is
-       recorded in this directory.
-
-objects/info/packs::
-       This file is to help dumb transports discover what packs
-       are available in this object store.  Whenever a pack is
-       added or removed, `git update-server-info` should be run
-       to keep this file up-to-date if the repository is
-       published for dumb transports.  `git repack` does this
-       by default.
-
-objects/info/alternates::
-       This file records paths to alternate object stores that
-       this object store borrows objects from, one pathname per
-       line. Note that not only native Git tools use it locally,
-       but the HTTP fetcher also tries to use it remotely; this
-       will usually work if you have relative paths (relative
-       to the object database, not to the repository!) in your
-       alternates file, but it will not work if you use absolute
-       paths unless the absolute path in filesystem and web URL
-       is the same. See also 'objects/info/http-alternates'.
-
-objects/info/http-alternates::
-       This file records URLs to alternate object stores that
-       this object store borrows objects from, to be used when
-       the repository is fetched over HTTP.
-
-refs::
-       References are stored in subdirectories of this
-       directory.  The `git prune` command knows to keep
-       objects reachable from refs found in this directory and
-       its subdirectories.
-
-refs/heads/`name`::
-       records tip-of-the-tree commit objects of branch `name`
-
-refs/tags/`name`::
-       records any object name (not necessarily a commit
-       object, or a tag object that points at a commit object).
-
-refs/remotes/`name`::
-       records tip-of-the-tree commit objects of branches copied
-       from a remote repository.
-
-packed-refs::
-       records the same information as refs/heads/, refs/tags/,
-       and friends record in a more efficient way.  See
-       linkgit:git-pack-refs[1].
-
-HEAD::
-       A symref (see glossary) to the `refs/heads/` namespace
-       describing the currently active branch.  It does not mean
-       much if the repository is not associated with any working tree
-       (i.e. a 'bare' repository), but a valid git repository
-       *must* have the HEAD file; some porcelains may use it to
-       guess the designated "default" branch of the repository
-       (usually 'master').  It is legal if the named branch
-       'name' does not (yet) exist.  In some legacy setups, it is
-       a symbolic link instead of a symref that points at the current
-       branch.
-+
-HEAD can also record a specific commit directly, instead of
-being a symref to point at the current branch.  Such a state
-is often called 'detached HEAD', and almost all commands work
-identically as normal.  See linkgit:git-checkout[1] for
-details.
-
-branches::
-       A slightly deprecated way to store shorthands to be used
-       to specify URL to `git fetch`, `git pull` and `git push`
-       commands is to store a file in `branches/'name'` and
-       give 'name' to these commands in place of 'repository'
-       argument.
-
-hooks::
-       Hooks are customization scripts used by various git
-       commands.  A handful of sample hooks are installed when
-       `git init` is run, but all of them are disabled by
-       default.  To enable, they need to be made executable.
-       Read link:hooks.html[hooks] for more details about
-       each hook.
-
-index::
-       The current index file for the repository.  It is
-       usually not found in a bare repository.
-
-info::
-       Additional information about the repository is recorded
-       in this directory.
-
-info/refs::
-       This file helps dumb transports discover what refs are
-       available in this repository.  If the repository is
-       published for dumb transports, this file should be
-       regenerated by `git update-server-info` every time a tag
-       or branch is created or modified.  This is normally done
-       from the `hooks/update` hook, which is run by the
-       `git-receive-pack` command when you `git push` into the
-       repository.
-
-info/grafts::
-       This file records fake commit ancestry information, to
-       pretend the set of parents a commit has is different
-       from how the commit was actually created.  One record
-       per line describes a commit and its fake parents by
-       listing their 40-byte hexadecimal object names separated
-       by a space and terminated by a newline.
-
-info/exclude::
-       This file, by convention among Porcelains, stores the
-       exclude pattern list. `.gitignore` is the per-directory
-       ignore file.  `git status`, `git add`, `git rm` and `git
-       clean` look at it but the core git commands do not look
-       at it.  See also: linkgit:gitignore[5].
-
-remotes::
-       Stores shorthands to be used to give URL and default
-       refnames to interact with remote repository to `git
-       fetch`, `git pull` and `git push` commands.
-
-logs::
-       Records of changes made to refs are stored in this
-       directory.  See the documentation on git-update-ref
-       for more information.
-
-logs/refs/heads/`name`::
-       Records all changes made to the branch tip named `name`.
-
-logs/refs/tags/`name`::
-       Records all changes made to the tag named `name`.
-
-shallow::
-       This is similar to `info/grafts` but is internally used
-       and maintained by shallow clone mechanism.  See `--depth`
-       option to linkgit:git-clone[1] and linkgit:git-fetch[1].

+History Simplification
+~~~~~~~~~~~~~~~~~~~~~~
+
+When optional paths are given, 'git-rev-list' simplifies commits with
+various strategies, according to the options you have selected.
+
+Suppose you specified `foo` as the <paths>.  We shall call commits
+that modify `foo` !TREESAME, and the rest TREESAME.  (In a diff
+filtered for `foo`, they look different and equal, respectively.)
+
+In the following, we will always refer to the same example history to
+illustrate the differences between simplification settings.  We assume
+that you are filtering for a file `foo` in this commit graph:
+-----------------------------------------------------------------------
+         .-A---M---N---O---P
+        /     /   /   /   /
+       I     B   C   D   E
+        \   /   /   /   /
+         `-------------'
+-----------------------------------------------------------------------
+The horizontal line of history A--P is taken to be the first parent of
+each merge.  The commits are:
+
+* `I` is the initial commit, in which `foo` exists with contents
+  "asdf", and a file `quux` exists with contents "quux".  Initial
+  commits are compared to an empty tree, so `I` is !TREESAME.
+
+* In `A`, `foo` contains just "foo".
+
+* `B` contains the same change as `A`.  Its merge `M` is trivial and
+  hence TREESAME to all parents.
+
+* `C` does not change `foo`, but its merge `N` changes it to "foobar",
+  so it is not TREESAME to any parent.
+
+* `D` sets `foo` to "baz".  Its merge `O` combines the strings from
+  `N` and `D` to "foobarbaz"; i.e., it is not TREESAME to any parent.
+
+* `E` changes `quux` to "xyzzy", and its merge `P` combines the
+  strings to "quux xyzzy".  Despite appearing interesting, `P` is
+  TREESAME to all parents.
 
-When optional paths are given, the default behaviour ('--dense') is to
-only output commits that changes at least one of them, and also ignore
-merges that do not touch the given paths.
+'rev-list' walks backwards through history, including or excluding
+commits based on whether '\--full-history' and/or parent rewriting
+(via '\--parents' or '\--children') are used.  The following settings
+are available.
+
+Default mode::
+
+       Commits are included if they are not TREESAME to any parent
+       (though this can be changed, see '\--sparse' below).  If the
+       commit was a merge, and it was TREESAME to one parent, follow
+       only that parent.  (Even if there are several TREESAME
+       parents, follow only one of them.)  Otherwise, follow all
+       parents.
++
+This results in:
++
+-----------------------------------------------------------------------
+         .-A---N---O
+        /         /
+       I---------D
+-----------------------------------------------------------------------
++
+Note how the rule to only follow the TREESAME parent, if one is
+available, removed `B` from consideration entirely.  `C` was
+considered via `N`, but is TREESAME.  Root commits are compared to an
+empty tree, so `I` is !TREESAME.
++
+Parent/child relations are only visible with --parents, but that does
+not affect the commits selected in default mode, so we have shown the
+parent lines.
+
+--full-history without parent rewriting::
+
+       This mode differs from the default in one point: always follow
+       all parents of a merge, even if it is TREESAME to one of them.
+       Even if more than one side of the merge has commits that are
+       included, this does not imply that the merge itself is!  In
+       the example, we get
++
+-----------------------------------------------------------------------
+       I  A  B  N  D  O
+-----------------------------------------------------------------------
++
+`P` and `M` were excluded because they are TREESAME to a parent.  `E`,
+`C` and `B` were all walked, but only `B` was !TREESAME, so the others
+do not appear.
++
+Note that without parent rewriting, it is not really possible to talk
+about the parent/child relationships between the commits, so we show
+them disconnected.
+
+--full-history with parent rewriting::
+
+       Ordinary commits are only included if they are !TREESAME
+       (though this can be changed, see '\--sparse' below).
++
+Merges are always included.  However, their parent list is rewritten:
+Along each parent, prune away commits that are not included
+themselves.  This results in
++
+-----------------------------------------------------------------------
+         .-A---M---N---O---P
+        /     /   /   /   /
+       I     B   /   D   /
+        \   /   /   /   /
+         `-------------'
+-----------------------------------------------------------------------
++
+Compare to '\--full-history' without rewriting above.  Note that `E`
+was pruned away because it is TREESAME, but the parent list of P was
+rewritten to contain `E`'s parent `I`.  The same happened for `C` and
+`N`.  Note also that `P` was included despite being TREESAME.
+
+In addition to the above settings, you can change whether TREESAME
+affects inclusion:
+
+--dense::
+
+       Commits that are walked are included if they are not TREESAME
+       to any parent.
+
+--sparse::
+
+       All commits that are walked are included.
++
+Note that without '\--full-history', this still simplifies merges: if
+one of the parents is TREESAME, we follow only that one, so the other
+sides of the merge are never walked.
 
-Use the '--sparse' flag to makes the command output all eligible commits
-(still subject to count and age limitation), but apply merge
-simplification nevertheless.

+history graph API
+=================
+
+The graph API is used to draw a text-based representation of the commit
+history.  The API generates the graph in a line-by-line fashion.
+
+Functions
+---------
+
+Core functions:
+
+* `graph_init()` creates a new `struct git_graph`
+
+* `graph_release()` destroys a `struct git_graph`, and frees the memory
+  associated with it.
+
+* `graph_update()` moves the graph to a new commit.
+
+* `graph_next_line()` outputs the next line of the graph into a strbuf.  It
+  does not add a terminating newline.
+
+* `graph_padding_line()` outputs a line of vertical padding in the graph.  It
+  is similar to `graph_next_line()`, but is guaranteed to never print the line
+  containing the current commit.  Where `graph_next_line()` would print the
+  commit line next, `graph_padding_line()` prints a line that simply extends
+  all branch lines downwards one row, leaving their positions unchanged.
+
+* `graph_is_commit_finished()` determines if the graph has output all lines
+  necessary for the current commit.  If `graph_update()` is called before all
+  lines for the current commit have been printed, the next call to
+  `graph_next_line()` will output an ellipsis, to indicate that a portion of
+  the graph was omitted.
+
+The following utility functions are wrappers around `graph_next_line()` and
+`graph_is_commit_finished()`.  They always print the output to stdout.
+They can all be called with a NULL graph argument, in which case no graph
+output will be printed.
+
+* `graph_show_commit()` calls `graph_next_line()` until it returns non-zero.
+  This prints all graph lines up to, and including, the line containing this
+  commit.  Output is printed to stdout.  The last line printed does not contain
+  a terminating newline.  This should not be called if the commit line has
+  already been printed, or it will loop forever.
+
+* `graph_show_oneline()` calls `graph_next_line()` and prints the result to
+  stdout.  The line printed does not contain a terminating newline.
+
+* `graph_show_padding()` calls `graph_padding_line()` and prints the result to
+  stdout.  The line printed does not contain a terminating newline.
+
+* `graph_show_remainder()` calls `graph_next_line()` until
+  `graph_is_commit_finished()` returns non-zero.  Output is printed to stdout.
+  The last line printed does not contain a terminating newline.  Returns 1 if
+  output was printed, and 0 if no output was necessary.
+
+* `graph_show_strbuf()` prints the specified strbuf to stdout, prefixing all
+  lines but the first with a graph line.  The caller is responsible for
+  ensuring graph output for the first line has already been printed to stdout.
+  (This can be done with `graph_show_commit()` or `graph_show_oneline()`.)  If
+  a NULL graph is supplied, the strbuf is printed as-is.
+
+* `graph_show_commit_msg()` is similar to `graph_show_strbuf()`, but it also
+  prints the remainder of the graph, if more lines are needed after the strbuf
+  ends.  It is better than directly calling `graph_show_strbuf()` followed by
+  `graph_show_remainder()` since it properly handles buffers that do not end in
+  a terminating newline.  The output printed by `graph_show_commit_msg()` will
+  end in a newline if and only if the strbuf ends in a newline.
+
+Data structure
+--------------
+`struct git_graph` is an opaque data type used to store the current graph
+state.
+
+Calling sequence
+----------------
+
+* Create a `struct git_graph` by calling `graph_init()`.  When using the
+  revision walking API, this is done automatically by `setup_revisions()` if
+  the '--graph' option is supplied.
+
+* Use the revision walking API to walk through a group of contiguous commits.
+  The `get_revision()` function automatically calls `graph_update()` each time
+  it is invoked.
+
+* For each commit, call `graph_next_line()` repeatedly, until
+  `graph_is_commit_finished()` returns non-zero.  Each call go
+  `graph_next_line()` will output a single line of the graph.  The resulting
+  lines will not contain any newlines.  `graph_next_line()` returns 1 if the
+  resulting line contains the current commit, or 0 if this is merely a line
+  needed to adjust the graph before or after the current commit.  This return
+  value can be used to determine where to print the commit summary information
+  alongside the graph output.
+
+Limitations
+-----------
+
+* `graph_update()` must be called with commits in topological order.  It should
+  not be called on a commit if it has already been invoked with an ancestor of
+  that commit, or the graph output will be incorrect.
+
+* `graph_update()` must be called on a contiguous group of commits.  If
+  `graph_update()` is called on a particular commit, it should later be called
+  on all parents of that commit.  Parents must not be skipped, or the graph
+  output will appear incorrect.
++
+`graph_update()` may be used on a pruned set of commits only if the parent list
+has been rewritten so as to include only ancestors from the pruned set.
+
+* The graph API does not currently support reverse commit ordering.  In
+  order to implement reverse ordering, the graphing API needs an
+  (efficient) mechanism to find the children of a commit.
+
+Sample usage
+------------
+
+------------
+struct commit *commit;
+struct git_graph *graph = graph_init(opts);
+
+while ((commit = get_revision(opts)) != NULL) {
+       graph_update(graph, commit);
+       while (!graph_is_commit_finished(graph))
+       {
+               struct strbuf sb;
+               int is_commit_line;
+
+               strbuf_init(&sb, 0);
+               is_commit_line = graph_next_line(graph, &sb);
+               fputs(sb.buf, stdout);
+
+               if (is_commit_line)
+                       log_tree_commit(opts, commit);
+               else
+                       putchar(opts->diffopt.line_termination);
+       }
+}
+
+graph_release(graph);

+
+Sample output

+not include any commit summary information--callers are responsible for
+outputting that information, if desired.

 parse-options API
 =================
 
-Talk about <parse-options.h>
+The parse-options API is used to parse and massage options in git
+and to provide a usage help with consistent look.
 
-(Pierre)
+Basics
+------
+
+The argument vector `argv[]` may usually contain mandatory or optional
+'non-option arguments', e.g. a filename or a branch, and 'options'.
+Options are optional arguments that start with a dash and
+that allow to change the behavior of a command.
+
+* There are basically three types of options:
+  'boolean' options,
+  options with (mandatory) 'arguments' and
+  options with 'optional arguments'
+  (i.e. a boolean option that can be adjusted).
+
+* There are basically two forms of options:
+  'Short options' consist of one dash (`-`) and one alphanumeric
+  character.
+  'Long options' begin with two dashes (`\--`) and some
+  alphanumeric characters.
+
+* Options are case-sensitive.
+  Please define 'lower-case long options' only.
+
+The parse-options API allows:
+
+* 'sticked' and 'separate form' of options with arguments.
+  `-oArg` is sticked, `-o Arg` is separate form.
+  `\--option=Arg` is sticked, `\--option Arg` is separate form.
+
+* Long options may be 'abbreviated', as long as the abbreviation
+  is unambiguous.
+
+* Short options may be bundled, e.g. `-a -b` can be specified as `-ab`.
+
+* Boolean long options can be 'negated' (or 'unset') by prepending
+  `no-`, e.g. `\--no-abbrev` instead of `\--abbrev`.
+
+* Options and non-option arguments can clearly be separated using the `\--`
+  option, e.g. `-a -b \--option \-- \--this-is-a-file` indicates that
+  `\--this-is-a-file` must not be processed as an option.
+
+Steps to parse options
+----------------------
+
+. `#include "parse-options.h"`
+
+. define a NULL-terminated
+  `static const char * const builtin_foo_usage[]` array
+  containing alternative usage strings
+
+. define `builtin_foo_options` array as described below
+  in section 'Data Structure'.
+
+. in `cmd_foo(int argc, const char **argv, const char *prefix)`
+  call
+
+       argc = parse_options(argc, argv, builtin_foo_options, builtin_foo_usage, flags);
++
+`parse_options()` will filter out the processed options of `argv[]` and leave the
+non-option arguments in `argv[]`.
+`argc` is updated appropriately because of the assignment.
++
+Flags are the bitwise-or of:
+
+`PARSE_OPT_KEEP_DASHDASH`::
+       Keep the `\--` that usually separates options from
+       non-option arguments.
+
+`PARSE_OPT_STOP_AT_NON_OPTION`::
+       Usually the whole argument vector is massaged and reordered.
+       Using this flag, processing is stopped at the first non-option
+       argument.
+
+Data Structure
+--------------
+
+The main data structure is an array of the `option` struct,
+say `static struct option builtin_add_options[]`.
+There are some macros to easily define options:
+
+`OPT__ABBREV(&int_var)`::
+       Add `\--abbrev[=<n>]`.
+
+`OPT__DRY_RUN(&int_var)`::
+       Add `-n, \--dry-run`.
+
+`OPT__QUIET(&int_var)`::
+       Add `-q, \--quiet`.
+
+`OPT__VERBOSE(&int_var)`::
+       Add `-v, \--verbose`.
+
+`OPT_GROUP(description)`::
+       Start an option group. `description` is a short string that
+       describes the group or an empty string.
+       Start the description with an upper-case letter.
+
+`OPT_BOOLEAN(short, long, &int_var, description)`::
+       Introduce a boolean option.
+       `int_var` is incremented on each use.
+
+`OPT_BIT(short, long, &int_var, description, mask)`::
+       Introduce a boolean option.
+       If used, `int_var` is bitwise-ored with `mask`.
+
+`OPT_SET_INT(short, long, &int_var, description, integer)`::
+       Introduce a boolean option.
+       If used, set `int_var` to `integer`.
+
+`OPT_SET_PTR(short, long, &ptr_var, description, ptr)`::
+       Introduce a boolean option.
+       If used, set `ptr_var` to `ptr`.
+
+`OPT_STRING(short, long, &str_var, arg_str, description)`::
+       Introduce an option with string argument.
+       The string argument is put into `str_var`.
+
+`OPT_INTEGER(short, long, &int_var, description)`::
+       Introduce an option with integer argument.
+       The integer is put into `int_var`.
+
+`OPT_DATE(short, long, &int_var, description)`::
+       Introduce an option with date argument, see `approxidate()`.
+       The timestamp is put into `int_var`.
+
+`OPT_CALLBACK(short, long, &var, arg_str, description, func_ptr)`::
+       Introduce an option with argument.
+       The argument will be fed into the function given by `func_ptr`
+       and the result will be put into `var`.
+       See 'Option Callbacks' below for a more elaborate description.
+
+`OPT_ARGUMENT(long, description)`::
+       Introduce a long-option argument that will be kept in `argv[]`.
+
+
+The last element of the array must be `OPT_END()`.
+
+If not stated otherwise, interpret the arguments as follows:
+
+* `short` is a character for the short option
+  (e.g. `\'e\'` for `-e`, use `0` to omit),
+
+* `long` is a string for the long option
+  (e.g. `"example"` for `\--example`, use `NULL` to omit),
+
+* `int_var` is an integer variable,
+
+* `str_var` is a string variable (`char *`),
+
+* `arg_str` is the string that is shown as argument
+  (e.g. `"branch"` will result in `<branch>`).
+  If set to `NULL`, three dots (`...`) will be displayed.
+
+* `description` is a short string to describe the effect of the option.
+  It shall begin with a lower-case letter and a full stop (`.`) shall be
+  omitted at the end.
+
+Option Callbacks
+----------------
+
+The function must be defined in this form:
+
+       int func(const struct option *opt, const char *arg, int unset)
+
+The callback mechanism is as follows:
+
+* Inside `funct`, the only interesting member of the structure
+  given by `opt` is the void pointer `opt->value`.
+  `\*opt->value` will be the value that is saved into `var`, if you
+  use `OPT_CALLBACK()`.
+  For example, do `*(unsigned long *)opt->value = 42;` to get 42
+  into an `unsigned long` variable.
+
+* Return value `0` indicates success and non-zero return
+  value will invoke `usage_with_options()` and, thus, die.
+
+* If the user negates the option, `arg` is `NULL` and `unset` is 1.
+
+Sophisticated option parsing
+----------------------------
+
+If you need, for example, option callbacks with optional arguments
+or without arguments at all, or if you need other special cases,
+that are not handled by the macros above, you need to specify the
+members of the `option` structure manually.
+
+This is not covered in this document, but well documented
+in `parse-options.h` itself.
+
+Examples
+--------
+
+See `test-parse-options.c` and
+`builtin-add.c`,
+`builtin-clone.c`,
+`builtin-commit.c`,
+`builtin-fetch.c`,
+`builtin-fsck.c`,
+`builtin-rm.c`
+for real-world examples.

+Remotes configuration API
+=========================
+
+The API in remote.h gives access to the configuration related to
+remotes. It handles all three configuration mechanisms historically
+and currently used by git, and presents the information in a uniform
+fashion. Note that the code also handles plain URLs without any
+configuration, giving them just the default information.
+
+struct remote
+-------------
+
+`name`::
+
+       The user's nickname for the remote
+
+`url`::
+
+       An array of all of the url_nr URLs configured for the remote
+
+`push`::
+
+        An array of refspecs configured for pushing, with
+        push_refspec being the literal strings, and push_refspec_nr
+        being the quantity.
+
+`fetch`::
+
+       An array of refspecs configured for fetching, with
+       fetch_refspec being the literal strings, and fetch_refspec_nr
+       being the quantity.
+
+`fetch_tags`::
+
+       The setting for whether to fetch tags (as a separate rule from
+       the configured refspecs); -1 means never to fetch tags, 0
+       means to auto-follow tags based on the default heuristic, 1
+       means to always auto-follow tags, and 2 means to fetch all
+       tags.
+
+`receivepack`, `uploadpack`::
+
+       The configured helper programs to run on the remote side, for
+       git-native protocols.
+
+`http_proxy`::
+
+       The proxy to use for curl (http, https, ftp, etc.) URLs.
+
+struct remotes can be found by name with remote_get(), and iterated
+through with for_each_remote(). remote_get(NULL) will return the
+default remote, given the current branch and configuration.
+
+struct refspec
+--------------
+
+A struct refspec holds the parsed interpretation of a refspec. If it
+will force updates (starts with a '+'), force is true. If it is a
+pattern (sides end with '*') pattern is true. src and dest are the two
+sides (if a pattern, only the part outside of the wildcards); if there
+is only one side, it is src, and dst is NULL; if sides exist but are
+empty (i.e., the refspec either starts or ends with ':'), the
+corresponding side is "".
+
+This parsing can be done to an array of strings to give an array of
+struct refpsecs with parse_ref_spec().
+
+remote_find_tracking(), given a remote and a struct refspec with
+either src or dst filled out, will fill out the other such that the
+result is in the "fetch" specification for the remote (note that this
+evaluates patterns and returns a single result).
+
+struct branch
+-------------
+
+Note that this may end up moving to branch.h
+
+struct branch holds the configuration for a branch. It can be looked
+up with branch_get(name) for "refs/heads/{name}", or with
+branch_get(NULL) for HEAD.
+
+It contains:
+
+`name`::
+
+       The short name of the branch.
+
+`refname`::
+
+       The full path for the branch ref.
+
+`remote_name`::
+
+       The name of the remote listed in the configuration.
+
+`remote`::
+
+       The struct remote for that remote.
+
+`merge_name`::
+
+       An array of the "merge" lines in the configuration.
+
+`merge`::
+
+       An array of the struct refspecs used for the merge lines. That
+       is, merge[i]->dst is a local tracking ref which should be
+       merged into this branch by default.
+
+`merge_nr`::
+
+       The number of merge configurations
+
+branch_has_merge_config() returns true if the given branch has merge
+configuration given.
+
+Other stuff
+-----------
+
+There is other stuff in remote.h that is related, in general, to the
+process of interacting with remotes.

 revision walking API
 ====================
 
+The revision walking API offers functions to build a list of revisions
+and then iterate over that list.
+
+Calling sequence
+----------------
+
+The walking API has a given calling sequence: first you need to
+initialize a rev_info structure, then add revisions to control what kind
+of revision list do you want to get, finally you can iterate over the
+revision list.
+
+Functions
+---------
+
+`init_revisions`::
+
+       Initialize a rev_info structure with default values. The second
+       parameter may be NULL or can be prefix path, and then the `.prefix`
+       variable will be set to it. This is typically the first function you
+       want to call when you want to deal with a revision list. After calling
+       this function, you are free to customize options, like set
+       `.ignore_merges` to 0 if you don't want to ignore merges, and so on. See
+       `revision.h` for a complete list of available options.
+
+`add_pending_object`::
+
+       This function can be used if you want to add commit objects as revision
+       information. You can use the `UNINTERESTING` object flag to indicate if
+       you want to include or exclude the given commit (and commits reachable
+       from the given commit) from the revision list.
++
+NOTE: If you have the commits as a string list then you probably want to
+use setup_revisions(), instead of parsing each string and using this
+function.
+
+`setup_revisions`::
+
+       Parse revision information, filling in the `rev_info` structure, and
+       removing the used arguments from the argument list. Returns the number
+       of arguments left that weren't recognized, which are also moved to the
+       head of the argument list. The last parameter is used in case no
+       parameter given by the first two arguments.
+
+`prepare_revision_walk`::
+
+       Prepares the rev_info structure for a walk. You should check if it
+       returns any error (non-zero return code) and if it does not, you can
+       start using get_revision() to do the iteration.
+
+`get_revision`::
+
+       Takes a pointer to a `rev_info` structure and iterates over it,
+       returning a `struct commit *` each time you call it. The end of the
+       revision list is indicated by returning a NULL pointer.
+
+Data structures
+---------------
+
 Talk about <revision.h>, things like:
 
 * two diff_options, one for path limiting, another for output;
-* calling sequence: init_revisions(), setup_revsions(), get_revision();
+* remaining functions;

 run-command API
 ===============
 
-Talk about <run-command.h>, and things like:
+The run-command API offers a versatile tool to run sub-processes with
+redirected input and output as well as with a modified environment
+and an alternate current directory.
 
-* Environment the command runs with (e.g. GIT_DIR);
-* File descriptors and pipes;
-* Exit status;
+A similar API offers the capability to run a function asynchronously,
+which is primarily used to capture the output that the function
+produces in the caller in order to process it.
 
-(Hannes, Dscho, Shawn)
+
+Functions
+---------
+
+`start_command`::
+
+       Start a sub-process. Takes a pointer to a `struct child_process`
+       that specifies the details and returns pipe FDs (if requested).
+       See below for details.
+
+`finish_command`::
+
+       Wait for the completion of a sub-process that was started with
+       start_command().
+
+`run_command`::
+
+       A convenience function that encapsulates a sequence of
+       start_command() followed by finish_command(). Takes a pointer
+       to a `struct child_process` that specifies the details.
+
+`run_command_v_opt`, `run_command_v_opt_cd`, `run_command_v_opt_cd_env`::
+
+       Convenience functions that encapsulate a sequence of
+       start_command() followed by finish_command(). The argument argv
+       specifies the program and its arguments. The argument opt is zero
+       or more of the flags `RUN_COMMAND_NO_STDIN`, `RUN_GIT_CMD`, or
+       `RUN_COMMAND_STDOUT_TO_STDERR` that correspond to the members
+       .no_stdin, .git_cmd, .stdout_to_stderr of `struct child_process`.
+       The argument dir corresponds the member .dir. The argument env
+       corresponds to the member .env.
+
+`start_async`::
+
+       Run a function asynchronously. Takes a pointer to a `struct
+       async` that specifies the details and returns a pipe FD
+       from which the caller reads. See below for details.
+
+`finish_async`::
+
+       Wait for the completion of an asynchronous function that was
+       started with start_async().
+
+
+Data structures
+---------------
+
+* `struct child_process`
+
+This describes the arguments, redirections, and environment of a
+command to run in a sub-process.
+
+The caller:
+
+1. allocates and clears (memset(&chld, 0, sizeof(chld));) a
+   struct child_process variable;
+2. initializes the members;
+3. calls start_command();
+4. processes the data;
+5. closes file descriptors (if necessary; see below);
+6. calls finish_command().
+
+The .argv member is set up as an array of string pointers (NULL
+terminated), of which .argv[0] is the program name to run (usually
+without a path). If the command to run is a git command, set argv[0] to
+the command name without the 'git-' prefix and set .git_cmd = 1.
+
+The members .in, .out, .err are used to redirect stdin, stdout,
+stderr as follows:
+
+. Specify 0 to request no special redirection. No new file descriptor
+  is allocated. The child process simply inherits the channel from the
+  parent.
+
+. Specify -1 to have a pipe allocated; start_command() replaces -1
+  by the pipe FD in the following way:
+
+       .in: Returns the writable pipe end into which the caller writes;
+               the readable end of the pipe becomes the child's stdin.
+
+       .out, .err: Returns the readable pipe end from which the caller
+               reads; the writable end of the pipe end becomes child's
+               stdout/stderr.
+
+  The caller of start_command() must close the so returned FDs
+  after it has completed reading from/writing to it!
+
+. Specify a file descriptor > 0 to be used by the child:
+
+       .in: The FD must be readable; it becomes child's stdin.
+       .out: The FD must be writable; it becomes child's stdout.
+       .err > 0 is not supported.
+
+  The specified FD is closed by start_command(), even if it fails to
+  run the sub-process!
+
+. Special forms of redirection are available by setting these members
+  to 1:
+
+       .no_stdin, .no_stdout, .no_stderr: The respective channel is
+               redirected to /dev/null.
+
+       .stdout_to_stderr: stdout of the child is redirected to its
+               stderr. This happens after stderr is itself redirected.
+               So stdout will follow stderr to wherever it is
+               redirected.
+
+To modify the environment of the sub-process, specify an array of
+string pointers (NULL terminated) in .env:
+
+. If the string is of the form "VAR=value", i.e. it contains '='
+  the variable is added to the child process's environment.
+
+. If the string does not contain '=', it names an environment
+  variable that will be removed from the child process's environment.
+
+To specify a new initial working directory for the sub-process,
+specify it in the .dir member.
+
+
+* `struct async`
+
+This describes a function to run asynchronously, whose purpose is
+to produce output that the caller reads.
+
+The caller:
+
+1. allocates and clears (memset(&asy, 0, sizeof(asy));) a
+   struct async variable;
+2. initializes .proc and .data;
+3. calls start_async();
+4. processes the data by reading from the fd in .out;
+5. closes .out;
+6. calls finish_async().
+
+The function pointer in .proc has the following signature:
+
+       int proc(int fd, void *data);
+
+. fd specifies a writable file descriptor to which the function must
+  write the data that it produces. The function *must* close this
+  descriptor before it returns.
+
+. data is the value that the caller has specified in the .data member
+  of struct async.
+
+. The return value of the function is 0 on success and non-zero
+  on failure. If the function indicates failure, finish_async() will
+  report failure as well.
+
+
+There are serious restrictions on what the asynchronous function can do
+because this facility is implemented by a pipe to a forked process on
+UNIX, but by a thread in the same address space on Windows:
+
+. It cannot change the program's state (global variables, environment,
+  etc.) in a way that the caller notices; in other words, .out is the
+  only communication channel to the caller.
+
+. It must not change the program's state that the caller of the
+  facility also uses.

 strbuf API
 ==========
 
-Talk about <strbuf.h>
+strbuf's are meant to be used with all the usual C string and memory
+APIs. Given that the length of the buffer is known, it's often better to
+use the mem* functions than a str* one (memchr vs. strchr e.g.).
+Though, one has to be careful about the fact that str* functions often
+stop on NULs and that strbufs may have embedded NULs.
 
-(Pierre, JC)
+An strbuf is NUL terminated for convenience, but no function in the
+strbuf API actually relies on the string being free of NULs.
+
+strbufs has some invariants that are very important to keep in mind:
+
+. The `buf` member is never NULL, so you it can be used in any usual C
+string operations safely. strbuf's _have_ to be initialized either by
+`strbuf_init()` or by `= STRBUF_INIT` before the invariants, though.
++
+Do *not* assume anything on what `buf` really is (e.g. if it is
+allocated memory or not), use `strbuf_detach()` to unwrap a memory
+buffer from its strbuf shell in a safe way. That is the sole supported
+way. This will give you a malloced buffer that you can later `free()`.
++
+However, it it totally safe to modify anything in the string pointed by
+the `buf` member, between the indices `0` and `len-1` (inclusive).
+
+. The `buf` member is a byte array that has at least `len + 1` bytes
+  allocated. The extra byte is used to store a `'\0'`, allowing the
+  `buf` member to be a valid C-string. Every strbuf function ensure this
+  invariant is preserved.
++
+NOTE: It is OK to "play" with the buffer directly if you work it this
+      way:
++
+----
+strbuf_grow(sb, SOME_SIZE); <1>
+strbuf_setlen(sb, sb->len + SOME_OTHER_SIZE);
+----
+<1> Here, the memory array starting at `sb->buf`, and of length
+`strbuf_avail(sb)` is all yours, and you can be sure that
+`strbuf_avail(sb)` is at least `SOME_SIZE`.
++
+NOTE: `SOME_OTHER_SIZE` must be smaller or equal to `strbuf_avail(sb)`.
++
+Doing so is safe, though if it has to be done in many places, adding the
+missing API to the strbuf module is the way to go.
++
+WARNING: Do _not_ assume that the area that is yours is of size `alloc
+- 1` even if it's true in the current implementation. Alloc is somehow a
+"private" member that should not be messed with. Use `strbuf_avail()`
+instead.
+
+Data structures
+---------------
+
+* `struct strbuf`
+
+This is string buffer structure. The `len` member can be used to
+determine the current length of the string, and `buf` member provides access to
+the string itself.
+
+Functions
+---------
+
+* Life cycle
+
+`strbuf_init`::
+
+       Initialize the structure. The second parameter can be zero or a bigger
+       number to allocate memory, in case you want to prevent further reallocs.
+
+`strbuf_release`::
+
+       Release a string buffer and the memory it used. You should not use the
+       string buffer after using this function, unless you initialize it again.
+
+`strbuf_detach`::
+
+       Detach the string from the strbuf and returns it; you now own the
+       storage the string occupies and it is your responsibility from then on
+       to release it with `free(3)` when you are done with it.
+
+`strbuf_attach`::
+
+       Attach a string to a buffer. You should specify the string to attach,
+       the current length of the string and the amount of allocated memory.
+       The amount must be larger than the string length, because the string you
+       pass is supposed to be a NUL-terminated string.  This string _must_ be
+       malloc()ed, and after attaching, the pointer cannot be relied upon
+       anymore, and neither be free()d directly.
+
+`strbuf_swap`::
+
+       Swap the contents of two string buffers.
+
+* Related to the size of the buffer
+
+`strbuf_avail`::
+
+       Determine the amount of allocated but unused memory.
+
+`strbuf_grow`::
+
+       Ensure that at least this amount of unused memory is available after
+       `len`. This is used when you know a typical size for what you will add
+       and want to avoid repetitive automatic resizing of the underlying buffer.
+       This is never a needed operation, but can be critical for performance in
+       some cases.
+
+`strbuf_setlen`::
+
+       Set the length of the buffer to a given value. This function does *not*
+       allocate new memory, so you should not perform a `strbuf_setlen()` to a
+       length that is larger than `len + strbuf_avail()`. `strbuf_setlen()` is
+       just meant as a 'please fix invariants from this strbuf I just messed
+       with'.
+
+`strbuf_reset`::
+
+       Empty the buffer by setting the size of it to zero.
+
+* Related to the contents of the buffer
+
+`strbuf_rtrim`::
+
+       Strip whitespace from the end of a string.
+
+`strbuf_cmp`::
+
+       Compare two buffers. Returns an integer less than, equal to, or greater
+       than zero if the first buffer is found, respectively, to be less than,
+       to match, or be greater than the second buffer.
+
+* Adding data to the buffer
+
+NOTE: All of these functions in this section will grow the buffer as
+      necessary.
+
+`strbuf_addch`::
+
+       Add a single character to the buffer.
+
+`strbuf_insert`::
+
+       Insert data to the given position of the buffer. The remaining contents
+       will be shifted, not overwritten.
+
+`strbuf_remove`::
+
+       Remove given amount of data from a given position of the buffer.
+
+`strbuf_splice`::
+
+       Remove the bytes between `pos..pos+len` and replace it with the given
+       data.
+
+`strbuf_add`::
+
+       Add data of given length to the buffer.
+
+`strbuf_addstr`::
+
+Add a NUL-terminated string to the buffer.
++
+NOTE: This function will *always* be implemented as an inline or a macro
+that expands to:
++
+----
+strbuf_add(..., s, strlen(s));
+----
++
+Meaning that this is efficient to write things like:
++
+----
+strbuf_addstr(sb, "immediate string");
+----
+
+`strbuf_addbuf`::
+
+       Copy the contents of an other buffer at the end of the current one.
+
+`strbuf_adddup`::
+
+       Copy part of the buffer from a given position till a given length to the
+       end of the buffer.
+
+`strbuf_expand`::
+
+       This function can be used to expand a format string containing
+       placeholders. To that end, it parses the string and calls the specified
+       function for every percent sign found.
++
+The callback function is given a pointer to the character after the `%`
+and a pointer to the struct strbuf.  It is expected to add the expanded
+version of the placeholder to the strbuf, e.g. to add a newline
+character if the letter `n` appears after a `%`.  The function returns
+the length of the placeholder recognized and `strbuf_expand()` skips
+over it.
++
+All other characters (non-percent and not skipped ones) are copied
+verbatim to the strbuf.  If the callback returned zero, meaning that the
+placeholder is unknown, then the percent sign is copied, too.
++
+In order to facilitate caching and to make it possible to give
+parameters to the callback, `strbuf_expand()` passes a context pointer,
+which can be used by the programmer of the callback as she sees fit.
+
+`strbuf_addf`::
+
+       Add a formatted string to the buffer.
+
+`strbuf_fread`::
+
+       Read a given size of data from a FILE* pointer to the buffer.
++
+NOTE: The buffer is rewinded if the read fails. If -1 is returned,
+`errno` must be consulted, like you would do for `read(3)`.
+`strbuf_read()`, `strbuf_read_file()` and `strbuf_getline()` has the
+same behaviour as well.
+
+`strbuf_read`::
+
+       Read the contents of a given file descriptor. The third argument can be
+       used to give a hint about the file size, to avoid reallocs.
+
+`strbuf_read_file`::
+
+       Read the contents of a file, specified by its path. The third argument
+       can be used to give a hint about the file size, to avoid reallocs.
+
+`strbuf_getline`::
+
+       Read a line from a FILE* pointer. The second argument specifies the line
+       terminator character, typically `'\n'`.
+
+`stripspace`::
+
+       Strip whitespace from a buffer. The second parameter controls if
+       comments are considered contents to be removed or not.
+
+`launch_editor`::

+string-list API
+===============
+
+The string_list API offers a data structure and functions to handle sorted
+and unsorted string lists.
+
+The 'string_list' struct used to be called 'path_list', but was renamed
+because it is not specific to paths.
+
+The caller:
+
+. Allocates and clears a `struct string_list` variable.
+
+. Initializes the members. You might want to set the flag `strdup_strings`
+  if the strings should be strdup()ed. For example, this is necessary
+  when you add something like git_path("..."), since that function returns
+  a static buffer that will change with the next call to git_path().
++
+If you need something advanced, you can manually malloc() the `items`
+member (you need this if you add things later) and you should set the
+`nr` and `alloc` members in that case, too.
+
+. Adds new items to the list, using `string_list_append` or
+  `string_list_insert`.
+
+. Can check if a string is in the list using `string_list_has_string` or
+  `unsorted_string_list_has_string` and get it from the list using
+  `string_list_lookup` for sorted lists.
+
+. Can sort an unsorted list using `sort_string_list`.
+
+. Finally it should free the list using `string_list_clear`.
+
+Example:
+
+----
+struct string_list list;
+int i;
+
+memset(&list, 0, sizeof(struct string_list));
+string_list_append("foo", &list);
+string_list_append("bar", &list);
+for (i = 0; i < list.nr; i++)
+       printf("%s\n", list.items[i].string)
+----
+
+NOTE: It is more efficient to build an unsorted list and sort it
+afterwards, instead of building a sorted list (`O(n log n)` instead of
+`O(n^2)`).
++
+However, if you use the list to check if a certain string was added
+already, you should not do that (using unsorted_string_list_has_string()),
+because the complexity would be quadratic again (but with a worse factor).
+
+Functions
+---------
+
+* General ones (works with sorted and unsorted lists as well)
+
+`print_string_list`::
+
+       Dump a string_list to stdout, useful mainly for debugging purposes. It
+       can take an optional header argument and it writes out the
+       string-pointer pairs of the string_list, each one in its own line.
+
+`string_list_clear`::
+
+       Free a string_list. The `string` pointer of the items will be freed in
+       case the `strdup_strings` member of the string_list is set. The second
+       parameter controls if the `util` pointer of the items should be freed
+       or not.
+
+* Functions for sorted lists only
+
+`string_list_has_string`::
+
+       Determine if the string_list has a given string or not.
+
+`string_list_insert`::
+
+       Insert a new element to the string_list. The returned pointer can be
+       handy if you want to write something to the `util` pointer of the
+       string_list_item containing the just added string.
++
+Since this function uses xrealloc() (which die()s if it fails) if the
+list needs to grow, it is safe not to check the pointer. I.e. you may
+write `string_list_insert(...)->util = ...;`.
+
+`string_list_lookup`::
+
+       Look up a given string in the string_list, returning the containing
+       string_list_item. If the string is not found, NULL is returned.
+
+* Functions for unsorted lists only
+
+`string_list_append`::
+
+       Append a new string to the end of the string_list.
+
+`sort_string_list`::
+
+       Make an unsorted list sorted.
+
+`unsorted_string_list_has_string`::
+
+       It's like `string_list_has_string()` but for unsorted lists.
++
+This function needs to look through all items, as opposed to its
+counterpart for sorted lists, which performs a binary search.
+
+Data structures
+---------------
+

-A tutorial introduction to git: part two
-========================================
-
-You should work through link:tutorial.html[A tutorial introduction to
-git] before reading this tutorial.
-
-The goal of this tutorial is to introduce two fundamental pieces of
-git's architecture--the object database and the index file--and to
-provide the reader with everything necessary to understand the rest
-of the git documentation.
-
-The git object database
------------------------
-
-Let's start a new project and create a small amount of history:
-
-------------------------------------------------
-$ mkdir test-project
-$ cd test-project
-$ git init
-Initialized empty Git repository in .git/
-$ echo 'hello world' > file.txt
-$ git add .
-$ git commit -a -m "initial commit"
-Created initial commit 54196cc2703dc165cbd373a65a4dcf22d50ae7f7
- create mode 100644 file.txt
-$ echo 'hello world!' >file.txt
-$ git commit -a -m "add emphasis"
-Created commit c4d59f390b9cfd4318117afde11d601c1085f241
-------------------------------------------------
-
-What are the 40 digits of hex that git responded to the commit with?
-
-We saw in part one of the tutorial that commits have names like this.
-It turns out that every object in the git history is stored under
-such a 40-digit hex name.  That name is the SHA1 hash of the object's
-contents; among other things, this ensures that git will never store
-the same data twice (since identical data is given an identical SHA1
-name), and that the contents of a git object will never change (since
-that would change the object's name as well).
-
-It is expected that the content of the commit object you created while
-following the example above generates a different SHA1 hash than
-the one shown above because the commit object records the time when
-it was created and the name of the person performing the commit.
-
-We can ask git about this particular object with the cat-file
-command. Don't copy the 40 hex digits from this example but use those
-from your own version. Note that you can shorten it to only a few
-characters to save yourself typing all 40 hex digits:
-

-$ git-cat-file -t 54196cc2
-commit
-$ git-cat-file commit 54196cc2
-tree 92b8b694ffb1675e5975148e1121810081dbdffe
-author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-
-initial commit
-------------------------------------------------
-
-A tree can refer to one or more "blob" objects, each corresponding to
-a file.  In addition, a tree can also refer to other tree objects,
-thus creating a directory hierarchy.  You can examine the contents of
-any tree using ls-tree (remember that a long enough initial portion
-of the SHA1 will also work):
-
-------------------------------------------------
-$ git ls-tree 92b8b694
-100644 blob 3b18e512dba79e4c8300dd08aeb37f8e728b8dad    file.txt
-------------------------------------------------
-
-Thus we see that this tree has one file in it.  The SHA1 hash is a
-reference to that file's data:
-
-------------------------------------------------
-$ git cat-file -t 3b18e512
-blob
-------------------------------------------------
-
-A "blob" is just file data, which we can also examine with cat-file:
-
-------------------------------------------------
-$ git cat-file blob 3b18e512
-hello world
-------------------------------------------------
-
-Note that this is the old file data; so the object that git named in
-its response to the initial tree was a tree with a snapshot of the
-directory state that was recorded by the first commit.
-
-All of these objects are stored under their SHA1 names inside the git
-directory:
-
-------------------------------------------------
-$ find .git/objects/
-.git/objects/
-.git/objects/pack
-.git/objects/info
-.git/objects/3b
-.git/objects/3b/18e512dba79e4c8300dd08aeb37f8e728b8dad

-.git/objects/c4
-.git/objects/c4/d59f390b9cfd4318117afde11d601c1085f241
-------------------------------------------------
-
-and the contents of these files is just the compressed data plus a
-header identifying their length and their type.  The type is either a
-blob, a tree, a commit, or a tag.
-
-The simplest commit to find is the HEAD commit, which we can find
-from .git/HEAD:
-
-------------------------------------------------
-$ cat .git/HEAD
-ref: refs/heads/master
-------------------------------------------------
-
-As you can see, this tells us which branch we're currently on, and it
-tells us this by naming a file under the .git directory, which itself
-contains a SHA1 name referring to a commit object, which we can
-examine with cat-file:
-
-------------------------------------------------
-$ cat .git/refs/heads/master
-c4d59f390b9cfd4318117afde11d601c1085f241
-$ git cat-file -t c4d59f39

-add emphasis
-------------------------------------------------
-
-The "tree" object here refers to the new state of the tree:
-
-------------------------------------------------
-$ git ls-tree d0492b36
-100644 blob a0423896973644771497bdc03eb99d5281615b51    file.txt
-$ git cat-file blob a0423896
-hello world!
-------------------------------------------------
-
-and the "parent" object refers to the previous commit:
-
-------------------------------------------------
-$ git-cat-file commit 54196cc2
-tree 92b8b694ffb1675e5975148e1121810081dbdffe

-committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-
-initial commit
-------------------------------------------------
-
-The tree object is the tree we examined first, and this commit is
-unusual in that it lacks any parent.
-
-Most commits have only one parent, but it is also common for a commit
-to have multiple parents.   In that case the commit represents a
-merge, with the parent references pointing to the heads of the merged
-branches.
-
-Besides blobs, trees, and commits, the only remaining type of object
-is a "tag", which we won't discuss here; refer to linkgit:git-tag[1]
-for details.
-
-So now we know how git uses the object database to represent a
-project's history:
-
-  * "commit" objects refer to "tree" objects representing the
-    snapshot of a directory tree at a particular point in the
-    history, and refer to "parent" commits to show how they're
-    connected into the project history.
-  * "tree" objects represent the state of a single directory,
-    associating directory names to "blob" objects containing file
-    data and "tree" objects containing subdirectory information.
-  * "blob" objects contain file data without any other structure.
-  * References to commit objects at the head of each branch are
-    stored in files under .git/refs/heads/.
-  * The name of the current branch is stored in .git/HEAD.
-
-Note, by the way, that lots of commands take a tree as an argument.
-But as we can see above, a tree can be referred to in many different
-ways--by the SHA1 name for that tree, by the name of a commit that
-refers to the tree, by the name of a branch whose head refers to that
-tree, etc.--and most such commands can accept any of these names.
-
-In command synopses, the word "tree-ish" is sometimes used to
-designate such an argument.
-
-The index file
---------------
-
-The primary tool we've been using to create commits is "git commit
--a", which creates a commit including every change you've made to
-your working tree.  But what if you want to commit changes only to
-certain files?  Or only certain changes to certain files?
-
-If we look at the way commits are created under the cover, we'll see
-that there are more flexible ways creating commits.
-
-Continuing with our test-project, let's modify file.txt again:
-
-------------------------------------------------
-$ echo "hello world, again" >>file.txt
-------------------------------------------------
-
-but this time instead of immediately making the commit, let's take an
-intermediate step, and ask for diffs along the way to keep track of
-what's happening:
-
-------------------------------------------------
-$ git diff
---- a/file.txt
-+++ b/file.txt
-@@ -1 +1,2 @@
- hello world!
-+hello world, again
-$ git add file.txt
-$ git diff
-------------------------------------------------
-
-The last diff is empty, but no new commits have been made, and the
-head still doesn't contain the new line:
-
-------------------------------------------------
-$ git-diff HEAD
-diff --git a/file.txt b/file.txt
-index a042389..513feba 100644
---- a/file.txt
-+++ b/file.txt
-@@ -1 +1,2 @@
- hello world!
-+hello world, again
-------------------------------------------------
-
-So "git diff" is comparing against something other than the head.
-The thing that it's comparing against is actually the index file,
-which is stored in .git/index in a binary format, but whose contents
-we can examine with ls-files:
-
-------------------------------------------------
-$ git ls-files --stage
-100644 513feba2e53ebbd2532419ded848ba19de88ba00 0       file.txt
-$ git cat-file -t 513feba2
-blob
-$ git cat-file blob 513feba2
-hello world!
-hello world, again
-------------------------------------------------
-
-So what our "git add" did was store a new blob and then put
-a reference to it in the index file.  If we modify the file again,
-we'll see that the new modifications are reflected in the "git-diff"
-output:
-
-------------------------------------------------
-$ echo 'again?' >>file.txt

-between the working directory and the last commit, or between the
-index and the last commit:

-
-At any time, we can create a new commit using "git commit" (without
-the -a option), and verify that the state committed only includes the
-changes stored in the index file, not the additional change that is
-still only in our working tree:
-
-------------------------------------------------
-$ git commit -m "repeat"
-$ git diff HEAD

-
-So by default "git commit" uses the index to create the commit, not
-the working tree; the -a option to commit tells it to first update
-the index with all changes in the working tree.
-
-Finally, it's worth looking at the effect of "git add" on the index
-file:
-
-------------------------------------------------
-$ echo "goodbye, world" >closing.txt
-$ git add closing.txt
-------------------------------------------------
-
-The effect of the "git add" was to add one entry to the index file:
-
-------------------------------------------------
-$ git ls-files --stage
-100644 8b9743b20d4b15be3955fc8d5cd2b09cd2336138 0       closing.txt

-------------------------------------------------
-
-And, as you can see with cat-file, this new entry refers to the
-current contents of the file:
-
-------------------------------------------------
-$ git cat-file blob 8b9743b2
-goodbye, world
-------------------------------------------------
-
-The "status" command is a useful way to get a quick summary of the
-situation:
-
-------------------------------------------------
-$ git status
-# On branch master
-# Changes to be committed:
-#   (use "git reset HEAD <file>..." to unstage)
-#
-#       new file: closing.txt
-#
-# Changed but not updated:
-#   (use "git add <file>..." to update what will be committed)
-#
-#       modified: file.txt
-#
-------------------------------------------------
-
-Since the current state of closing.txt is cached in the index file,
-it is listed as "Changes to be committed".  Since file.txt has
-changes in the working directory that aren't reflected in the index,
-it is marked "changed but not updated".  At this point, running "git
-commit" would create a commit that added closing.txt (with its new
-contents), but that didn't modify file.txt.
-
-Also, note that a bare "git diff" shows the changes to file.txt, but
-not the addition of closing.txt, because the version of closing.txt
-in the index file is identical to the one in the working directory.
-
-In addition to being the staging area for new commits, the index file
-is also populated from the object database when checking out a
-branch, and is used to hold the trees involved in a merge operation.
-See the link:core-tutorial.html[core tutorial] and the relevant man
-pages for details.
-
-What next?
-----------
-
-At this point you should know everything necessary to read the man
-pages for any of the git commands; one good place to start would be
-with the commands mentioned in link:everyday.html[Everyday git].  You
-should be able to find any unknown jargon in the
-link:glossary.html[Glossary].

-A tutorial introduction to git (for version 1.5.1 or newer)
-===========================================================
-
-This tutorial explains how to import a new project into git, make
-changes to it, and share changes with other developers.
-
-If you are instead primarily interested in using git to fetch a project,
-for example, to test the latest version, you may prefer to start with
-the first two chapters of link:user-manual.html[The Git User's Manual].
-
-First, note that you can get documentation for a command such as "git
-diff" with:
-
-------------------------------------------------
-$ man git-diff
-------------------------------------------------
-
-It is a good idea to introduce yourself to git with your name and
-public email address before doing any operation.  The easiest
-way to do so is:
-
-------------------------------------------------
-$ git config --global user.name "Your Name Comes Here"
-$ git config --global user.email you@yourdomain.example.com
-------------------------------------------------
-
-
-Importing a new project
------------------------
-
-Assume you have a tarball project.tar.gz with your initial work.  You
-can place it under git revision control as follows.
-
-------------------------------------------------
-$ tar xzf project.tar.gz
-$ cd project
-$ git init
-------------------------------------------------
-
-Git will reply
-
-------------------------------------------------
-Initialized empty Git repository in .git/
-------------------------------------------------
-
-You've now initialized the working directory--you may notice a new
-directory created, named ".git".
-
-Next, tell git to take a snapshot of the contents of all files under the
-current directory (note the '.'), with linkgit:git-add[1]:
-
-------------------------------------------------
-$ git add .
-------------------------------------------------
-
-This snapshot is now stored in a temporary staging area which git calls
-the "index".  You can permanently store the contents of the index in the
-repository with linkgit:git-commit[1]:
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-This will prompt you for a commit message.  You've now stored the first
-version of your project in git.
-
-Making changes
---------------
-
-Modify some files, then add their updated contents to the index:
-
-------------------------------------------------
-$ git add file1 file2 file3
-------------------------------------------------
-
-You are now ready to commit.  You can see what is about to be committed
-using linkgit:git-diff[1] with the --cached option:
-
-------------------------------------------------
-$ git diff --cached
-------------------------------------------------
-
-(Without --cached, linkgit:git-diff[1] will show you any changes that
-you've made but not yet added to the index.)  You can also get a brief
-summary of the situation with linkgit:git-status[1]:
-
-------------------------------------------------
-$ git status
-# On branch master
-# Changes to be committed:
-#   (use "git reset HEAD <file>..." to unstage)
-#
-#      modified:   file1
-#      modified:   file2
-#      modified:   file3
-#
-------------------------------------------------
-
-If you need to make any further adjustments, do so now, and then add any
-newly modified content to the index.  Finally, commit your changes with:
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-This will again prompt your for a message describing the change, and then
-record a new version of the project.
-
-Alternatively, instead of running `git add` beforehand, you can use
-
-------------------------------------------------
-$ git commit -a
-------------------------------------------------
-
-which will automatically notice any modified (but not new) files, add
-them to the index, and commit, all in one step.
-
-A note on commit messages: Though not required, it's a good idea to
-begin the commit message with a single short (less than 50 character)
-line summarizing the change, followed by a blank line and then a more
-thorough description.  Tools that turn commits into email, for
-example, use the first line on the Subject: line and the rest of the
-commit in the body.
-
-Git tracks content not files
-----------------------------
-
-Many revision control systems provide an "add" command that tells the
-system to start tracking changes to a new file.  Git's "add" command
-does something simpler and more powerful: `git add` is used both for new
-and newly modified files, and in both cases it takes a snapshot of the
-given files and stages that content in the index, ready for inclusion in
-the next commit.
-
-Viewing project history
------------------------
-
-At any point you can view the history of your changes using
-
-------------------------------------------------
-$ git log
-------------------------------------------------
-
-If you also want to see complete diffs at each step, use
-
-------------------------------------------------
-$ git log -p
-------------------------------------------------
-
-Often the overview of the change is useful to get a feel of
-each step
-
-------------------------------------------------
-$ git log --stat --summary
-------------------------------------------------
-
-Managing branches
------------------
-
-A single git repository can maintain multiple branches of
-development.  To create a new branch named "experimental", use
-
-------------------------------------------------
-$ git branch experimental
-------------------------------------------------
-
-If you now run
-
-------------------------------------------------
-$ git branch
-------------------------------------------------
-
-you'll get a list of all existing branches:
-
-------------------------------------------------
-  experimental
-* master
-------------------------------------------------
-
-The "experimental" branch is the one you just created, and the
-"master" branch is a default branch that was created for you
-automatically.  The asterisk marks the branch you are currently on;
-type
-
-------------------------------------------------
-$ git checkout experimental
-------------------------------------------------
-
-to switch to the experimental branch.  Now edit a file, commit the
-change, and switch back to the master branch:
-
-------------------------------------------------
-(edit file)
-$ git commit -a
-$ git checkout master
-------------------------------------------------
-
-Check that the change you made is no longer visible, since it was
-made on the experimental branch and you're back on the master branch.
-
-You can make a different change on the master branch:
-
-------------------------------------------------
-(edit file)
-$ git commit -a
-------------------------------------------------
-
-at this point the two branches have diverged, with different changes
-made in each.  To merge the changes made in experimental into master, run
-
-------------------------------------------------
-$ git merge experimental
-------------------------------------------------
-
-If the changes don't conflict, you're done.  If there are conflicts,
-markers will be left in the problematic files showing the conflict;
-
-------------------------------------------------
-$ git diff
-------------------------------------------------
-
-will show this.  Once you've edited the files to resolve the
-conflicts,
-
-------------------------------------------------
-$ git commit -a

-
-will show a nice graphical representation of the resulting history.
-
-At this point you could delete the experimental branch with
-
-------------------------------------------------
-$ git branch -d experimental

-
-This command ensures that the changes in the experimental branch are
-already in the current branch.
-

-$ git branch -D crazy-idea
--------------------------------------
-
-Branches are cheap and easy, so this is a good way to try something
-out.
-
-Using git for collaboration
----------------------------
-
-Suppose that Alice has started a new project with a git repository in
-/home/alice/project, and that Bob, who has a home directory on the
-same machine, wants to contribute.
-
-Bob begins with:
-
-------------------------------------------------
-$ git clone /home/alice/project myrepo
-------------------------------------------------
-
-This creates a new directory "myrepo" containing a clone of Alice's
-repository.  The clone is on an equal footing with the original
-project, possessing its own copy of the original project's history.
-
-Bob then makes some changes and commits them:
-
-------------------------------------------------
-(edit files)
-$ git commit -a
-(repeat as necessary)
-------------------------------------------------
-
-When he's ready, he tells Alice to pull changes from the repository
-at /home/bob/myrepo.  She does this with:
-
-------------------------------------------------
-$ cd /home/alice/project
-$ git pull /home/bob/myrepo master
-------------------------------------------------
-
-This merges the changes from Bob's "master" branch into Alice's
-current branch.  If Alice has made her own changes in the meantime,
-then she may need to manually fix any conflicts.  (Note that the
-"master" argument in the above command is actually unnecessary, as it
-is the default.)
-
-The "pull" command thus performs two operations: it fetches changes
-from a remote branch, then merges them into the current branch.
-
-When you are working in a small closely knit group, it is not
-unusual to interact with the same repository over and over
-again.  By defining 'remote' repository shorthand, you can make
-it easier:
-
-------------------------------------------------
-$ git remote add bob /home/bob/myrepo
-------------------------------------------------
-
-With this, Alice can perform the first operation alone using the
-"git fetch" command without merging them with her own branch,
-using:
-
--------------------------------------
-$ git fetch bob
--------------------------------------
-
-Unlike the longhand form, when Alice fetches from Bob using a
-remote repository shorthand set up with `git remote`, what was
-fetched is stored in a remote tracking branch, in this case
-`bob/master`.  So after this:
-
--------------------------------------
-$ git log -p master..bob/master
--------------------------------------
-
-shows a list of all the changes that Bob made since he branched from
-Alice's master branch.
-
-After examining those changes, Alice
-could merge the changes into her master branch:
-
--------------------------------------
-$ git merge bob/master
--------------------------------------
-
-This `merge` can also be done by 'pulling from her own remote
-tracking branch', like this:
-
--------------------------------------
-$ git pull . remotes/bob/master
--------------------------------------
-
-Note that git pull always merges into the current branch,
-regardless of what else is given on the command line.
-
-Later, Bob can update his repo with Alice's latest changes using
-
--------------------------------------
-$ git pull
--------------------------------------
-
-Note that he doesn't need to give the path to Alice's repository;
-when Bob cloned Alice's repository, git stored the location of her
-repository in the repository configuration, and that location is
-used for pulls:
-
--------------------------------------
-$ git config --get remote.origin.url
-/home/alice/project
--------------------------------------
-
-(The complete configuration created by git-clone is visible using
-"git config -l", and the linkgit:git-config[1] man page
-explains the meaning of each option.)
-
-Git also keeps a pristine copy of Alice's master branch under the
-name "origin/master":
-
--------------------------------------
-$ git branch -r
-  origin/master
--------------------------------------
-
-If Bob later decides to work from a different host, he can still
-perform clones and pulls using the ssh protocol:
-
--------------------------------------
-$ git clone alice.org:/home/alice/project myrepo
--------------------------------------
-
-Alternatively, git has a native protocol, or can use rsync or http;
-see linkgit:git-pull[1] for details.
-
-Git can also be used in a CVS-like mode, with a central repository
-that various users push changes to; see linkgit:git-push[1] and
-link:cvs-migration.html[git for CVS users].
-
-Exploring history
------------------
-
-Git history is represented as a series of interrelated commits.  We
-have already seen that the git log command can list those commits.
-Note that first line of each git log entry also gives a name for the
-commit:
-
--------------------------------------
-$ git log
-commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
-Author: Junio C Hamano <junkio@cox.net>
-Date:   Tue May 16 17:18:22 2006 -0700
-
-    merge-base: Clarify the comments on post processing.
--------------------------------------
-
-We can give this name to git show to see the details about this
-commit.
-
--------------------------------------
-$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
--------------------------------------
-
-But there are other ways to refer to commits.  You can use any initial
-part of the name that is long enough to uniquely identify the commit:
-
--------------------------------------
-$ git show c82a22c39c  # the first few characters of the name are
-                       # usually enough
-$ git show HEAD                # the tip of the current branch
-$ git show experimental        # the tip of the "experimental" branch
--------------------------------------
-
-Every commit usually has one "parent" commit
-which points to the previous state of the project:
-
--------------------------------------
-$ git show HEAD^  # to see the parent of HEAD
-$ git show HEAD^^ # to see the grandparent of HEAD
-$ git show HEAD~4 # to see the great-great grandparent of HEAD
--------------------------------------
-
-Note that merge commits may have more than one parent:
-
--------------------------------------
-$ git show HEAD^1 # show the first parent of HEAD (same as HEAD^)
-$ git show HEAD^2 # show the second parent of HEAD
--------------------------------------
-
-You can also give commits names of your own; after running
-
--------------------------------------
-$ git-tag v2.5 1b2e1d63ff
--------------------------------------
-
-you can refer to 1b2e1d63ff by the name "v2.5".  If you intend to
-share this name with other people (for example, to identify a release
-version), you should create a "tag" object, and perhaps sign it; see
-linkgit:git-tag[1] for details.
-
-Any git command that needs to know a commit can take any of these
-names.  For example:
-
--------------------------------------
-$ git diff v2.5 HEAD    # compare the current HEAD to v2.5
-$ git branch stable v2.5 # start a new branch named "stable" based
-                        # at v2.5
-$ git reset --hard HEAD^ # reset your current branch and working
-                        # directory to its state at HEAD^
--------------------------------------
-
-Be careful with that last command: in addition to losing any changes
-in the working directory, it will also remove all later commits from
-this branch.  If this branch is the only branch containing those
-commits, they will be lost.  Also, don't use "git reset" on a
-publicly-visible branch that other developers pull from, as it will
-force needless merges on other developers to clean up the history.
-If you need to undo changes that you have pushed, use linkgit:git-revert[1]
-instead.
-
-The git grep command can search for strings in any version of your
-project, so
-
--------------------------------------
-$ git grep "hello" v2.5
--------------------------------------
-
-searches for all occurrences of "hello" in v2.5.
-
-If you leave out the commit name, git grep will search any of the
-files it manages in your current directory.  So
-
--------------------------------------
-$ git grep "hello"
--------------------------------------
-
-is a quick way to search just the files that are tracked by git.
-
-Many git commands also take sets of commits, which can be specified
-in a number of ways.  Here are some examples with git log:
-
--------------------------------------
-$ git log v2.5..v2.6            # commits between v2.5 and v2.6
-$ git log v2.5..                # commits since v2.5
-$ git log --since="2 weeks ago" # commits from the last 2 weeks
-$ git log v2.5.. Makefile       # commits since v2.5 which modify
-                               # Makefile
--------------------------------------
-
-You can also give git log a "range" of commits where the first is not
-necessarily an ancestor of the second; for example, if the tips of
-the branches "stable-release" and "master" diverged from a common
-commit some time ago, then
-
--------------------------------------
-$ git log stable..experimental
--------------------------------------
-
-will list commits made in the experimental branch but not in the
-stable branch, while
-
--------------------------------------
-$ git log experimental..stable
--------------------------------------
-
-will show the list of commits made on the stable branch but not
-the experimental branch.
-
-The "git log" command has a weakness: it must present commits in a
-list.  When the history has lines of development that diverged and
-then merged back together, the order in which "git log" presents
-those commits is meaningless.
-
-Most projects with multiple contributors (such as the linux kernel,
-or git itself) have frequent merges, and gitk does a better job of
-visualizing their history.  For example,
-
--------------------------------------
-$ gitk --since="2 weeks ago" drivers/
--------------------------------------
-
-allows you to browse any commits from the last 2 weeks of commits
-that modified files under the "drivers" directory.  (Note: you can
-adjust gitk's fonts by holding down the control key while pressing
-"-" or "+".)
-
-Finally, most commands that take filenames will optionally allow you
-to precede any filename by a commit, to specify a particular version
-of the file:
-
--------------------------------------
-$ git diff v2.5:Makefile HEAD:Makefile.in
--------------------------------------
-
-You can also use "git show" to see any such file:
-
--------------------------------------
-$ git show v2.5:Makefile
--------------------------------------
-
-Next Steps
-----------
-
-This tutorial should be enough to perform basic distributed revision
-control for your projects.  However, to fully understand the depth
-and power of git you need to understand two simple ideas on which it
-is based:
-
-  * The object database is the rather elegant system used to
-    store the history of your project--files, directories, and
-    commits.
-
-  * The index file is a cache of the state of a directory tree,
-    used to create commits, check out working directories, and
-    hold the various trees involved in a merge.
-
-link:tutorial-2.html[Part two of this tutorial] explains the object
-database, the index file, and a few other odds and ends that you'll
-need to make the most of git.
-
-If you don't want to continue with that right away, a few other
-digressions that may be interesting at this point are:
-
-  * linkgit:git-format-patch[1], linkgit:git-am[1]: These convert
-    series of git commits into emailed patches, and vice versa,
-    useful for projects such as the linux kernel which rely heavily
-    on emailed patches.
-
-  * linkgit:git-bisect[1]: When there is a regression in your
-    project, one way to track down the bug is by searching through
-    the history to find the exact commit that's to blame.  Git bisect
-    can help you perform a binary search for that commit.  It is
-    smart enough to perform a close-to-optimal search even in the
-    case of complex non-linear history with lots of merged branches.

+The name of one of the following can be used instead

+* a remote in the git configuration file: `$GIT_DIR/config`,
+* a file in the `$GIT_DIR/remotes` directory, or
+* a file in the `$GIT_DIR/branches` directory.
 
-------------
+All of these also allow you to omit the refspec from the command line
+because they each contain a refspec which git will use by default.
 
-Then such a short-hand is specified in place of
-<repository> without <refspec> parameters on the command
-line, <refspec> specified on `Push:` lines or `Pull:`
-lines are used for `git-push` and `git-fetch`/`git-pull`,
-respectively.  Multiple `Push:` and `Pull:` lines may

+Named remote in configuration file

-Or, equivalently, in the `$GIT_DIR/config` (note the use

+or even by a manual edit to the `$GIT_DIR/config` file.  The URL of
+this remote will be used to access the repository.  The refspec
+of this remote will be used by default when you do

-name of remote head (URL fragment notation).

+appp.sh is a script that is supposed to be used together with ExternalEditor
+for Mozilla Thundebird. It will let you include patches inline in e-mails
+in an easy way.
+
+Usage:
+- Generate the patch with git format-patch.
+- Start writing a new e-mail in Thunderbird.
+- Press the external editor button (or Ctrl-E) to run appp.sh
+- Select the previosly generated patch file.
+- Finish editing the e-mail.
+
+Any text that is entered into the message editor before appp.sh is called
+will be moved to the section between the --- and the diffstat.
+
+All S-O-B:s and Cc:s in the patch will be added to the CC list.
+
+To set it up, just install External Editor and tell it to use appp.sh as the
+editor.
+
+Zenity is a required dependency.

+The po/git-gui.pot file is updated by the internationalization
+coordinator from time to time.  You _could_ update it yourself, but
+translators are discouraged from doing so because we would want all
+language teams to be working off of the same version of git-gui.pot.
+
+****************************************************************
+
+This section is a note to the internationalization coordinator, and
+translators do not have to worry about it too much.
+
+The message template file po/git-gui.pot needs to be kept up to date
+relative to the software the translations apply to, and it is the
+responsibility of the internationalization coordinator.
+
+When updating po/git-gui.pot file, however, _never_ run "msgmerge -U
+po/xx.po" for individual language translations, unless you are absolutely
+sure that there is no outstanding work on translation for language xx.
+Doing so will create unnecessary merge conflicts and force needless
+re-translation on translators.  The translator however may not have access
+to the msgmerge tool, in which case the coordinator may run it for the
+translator as a service.
+
+But mistakes do happen.  Suppose a translation was based on an older
+version X, the POT file was updated at version Y and then msgmerge was run
+at version Z for the language, and the translator sent in a patch based on
+version X:
+
+         ? translated
+        /
+    ---X---Y---Z (master)
+
+The coordinator could recover from such a mistake by first applying the
+patch to X, replace the translated file in Z, and then running msgmerge
+again based on the updated POT file and commit the result.  The sequence
+would look like this:
+
+    $ git checkout X
+    $ git am -s xx.patch
+    $ git checkout master
+    $ git checkout HEAD@{1} po/xx.po
+    $ msgmerge -U po/xx.po po/git-gui.pot
+    $ git commit -c HEAD@{1} po/xx.po
+
+State in the message that the translated messages are based on a slightly
+older version, and msgmerge was run to incorporate changes to message
+templates from the updated POT file.  The result needs to be further
+translated, but at least the messages that were updated by the patch that
+were not changed by the POT update will survive the process and do not
+need to be re-translated.

+Projects list file format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instead of having gitweb find repositories by scanning filesystem starting
+from $projectroot (or $projects_list, if it points to directory), you can
+provide list of projects by setting $projects_list to a text file with list
+of projects (and some additional info).  This file uses the following
+format:
+
+One record (for project / repository) per line, whitespace separated fields;
+does not support (at least for now) lines continuation (newline escaping).
+Leading and trailing whitespace are ignored, any run of whitespace can be
+used as field separator (rules for Perl's "split(' ', $line)").  Keyed by
+the first field, which is project name, i.e. path to repository GIT_DIR
+relative to $projectroot.  Fields use modified URI encoding, defined in
+RFC 3986, section 2.1 (Percent-Encoding), or rather "Query string encoding"
+(see http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference
+being that SP (' ') can be encoded as '+' (and therefore '+' has to be also
+percent-encoded).  Reserved characters are: '%' (used for encoding), '+'
+(can be used to encode SPACE), all whitespace characters as defined in Perl,
+including SP, TAB and LF, (used to separate fields in a record).
+
+Currently list of fields is
+ * <repository path>  - path to repository GIT_DIR, relative to $projectroot
+ * <repository owner> - displayed as repository owner, preferably full name,
+                        or email, or both

+You can additionally use $projects_list file to limit which repositories
+are visible, and together with $strict_export to limit access to

+threadsafe. It does provide some error checking to help prevent temp file refs
+writing over one another.

+In general, the L<File::Handle> returned should not be closed by consumers as

+ * Conventional binary search loop looks like this:
+ *
+ *     unsigned lo, hi;
+ *      do {
+ *              unsigned mi = (lo + hi) / 2;
+ *              int cmp = "entry pointed at by mi" minus "target";
+ *              if (!cmp)
+ *                      return (mi is the wanted one)
+ *              if (cmp > 0)
+ *                      hi = mi; "mi is larger than target"
+ *              else
+ *                      lo = mi+1; "mi is smaller than target"
+ *      } while (lo < hi);
+ *
+ * The invariants are:
+ *
+ * - When entering the loop, lo points at a slot that is never
+ *   above the target (it could be at the target), hi points at a
+ *   slot that is guaranteed to be above the target (it can never
+ *   be at the target).
+ *
+ * - We find a point 'mi' between lo and hi (mi could be the same
+ *   as lo, but never can be as same as hi), and check if it hits
+ *   the target.  There are three cases:
+ *
+ *    - if it is a hit, we are happy.
+ *
+ *    - if it is strictly higher than the target, we set it to hi,
+ *      and repeat the search.
+ *
+ *    - if it is strictly lower than the target, we update lo to
+ *      one slot after it, because we allow lo to be at the target.
+ *
+ *   If the loop exits, there is no matching entry.
+ *
+ * When choosing 'mi', we do not have to take the "middle" but
+ * anywhere in between lo and hi, as long as lo <= mi < hi is
+ * satisfied.  When we somehow know that the distance between the
+ * target and lo is much shorter than the target and hi, we could
+ * pick mi that is much closer to lo than the midway.
+ *
+ * Now, we can take advantage of the fact that SHA-1 is a good hash
+ * function, and as long as there are enough entries in the table, we
+ * can expect uniform distribution.  An entry that begins with for
+ * example "deadbeef..." is much likely to appear much later than in
+ * the midway of the table.  It can reasonably be expected to be near
+ * 87% (222/256) from the top of the table.
+ *
+ * However, we do not want to pick "mi" too precisely.  If the entry at
+ * the 87% in the above example turns out to be higher than the target
+ * we are looking for, we would end up narrowing the search space down
+ * only by 13%, instead of 50% we would get if we did a simple binary
+ * search.  So we would want to hedge our bets by being less aggressive.
+ *
+ * The table at "table" holds at least "nr" entries of "elem_size"
+ * bytes each.  Each entry has the SHA-1 key at "key_offset".  The
+ * table is sorted by the SHA-1 key of the entries.  The caller wants
+ * to find the entry with "key", and knows that the entry at "lo" is
+ * not higher than the entry it is looking for, and that the entry at
+ * "hi" is higher than the entry it is looking for.

+Skipping Tests
+--------------
+
+In some environments, certain tests have no way of succeeding
+due to platform limitation, such as lack of 'unzip' program, or
+filesystem that do not allow arbitrary sequence of non-NUL bytes
+as pathnames.
+
+You should be able to say something like
+
+    $ GIT_SKIP_TESTS=t9200.8 sh ./t9200-git-cvsexport-commit.sh
+
+and even:
+
+    $ GIT_SKIP_TESTS='t[0-4]??? t91?? t9200.8' make
+
+to omit such tests.  The value of the environment variable is a
+SP separated list of patterns that tells which tests to skip,
+and either can match the "t[0-9]{4}" part to skip the whole
+test, or t[0-9]{4} followed by ".$number" to say which
+particular test to skip.
+
+Note that some tests in the existing test suite rely on previous
+test item, so you cannot arbitrarily disable one and expect the
+remainder of test to check what the test originally was intended
+to check.

+#
+# 1) blob_2 is a delta with blob_1 for base and blob_3 is a delta with blob2
+#    for base, such that blob_3 delta depth is 2;
+#
+# 2) the bulk of object data is uncompressible so the text part remains
+#    visible;

-################################################################
-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-                  o---o---o---o---o---o---o---o---o---o "next"
-                 /       /           /           /
-                /   a---a---b A     /           /
-               /   /               /           /
-              /   /   c---c---c---c B         /
-             /   /   /             \         /
-            /   /   /   b---b C     \       /
-           /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-       git-rev-list ^master ^topic next
-       git-rev-list ^master        next
-
-       if these match, topic has not merged in next at all.
-
-To compute (2):
-
-       git-rev-list master..topic
-
-       if this is empty, it is fully merged to "master".

+################################################################
+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+   merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+   it is deleted.  If you need to build on top of it to correct
+   earlier mistakes, a new topic branch is created by forking at
+   the tip of the "master".  This is not strictly necessary, but
+   it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+   branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next".  Young
+    topic branches can have stupid mistakes you would rather
+    clean up before publishing, and things that have not been
+    merged into other branches can be easily rebased without
+    affecting other people.  But once it is published, you would
+    not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+    Then you can delete it.  More importantly, you should not
+    build on top of it -- other people may already want to
+    change things related to the topic as patches against your
+    "master", so if you need further changes, it is better to
+    fork the topic (perhaps with the same name) afresh from the
+    tip of "master".
+
+Let's look at this example:
+
+                  o---o---o---o---o---o---o---o---o---o "next"
+                 /       /           /           /
+                /   a---a---b A     /           /
+               /   /               /           /
+              /   /   c---c---c---c B         /
+             /   /   /             \         /
+            /   /   /   b---b C     \       /
+           /   /   /   /             \     /
+    ---o---o---o---o---o---o---o---o---o---o---o "master"
+
+
+A, B and C are topic branches.
+
+ * A has one fix since it was merged up to "next".
+
+ * B has finished.  It has been fully merged up to "master" and "next",
+   and is ready to be deleted.
+
+ * C has not merged to "next" at all.
+
+We would want to allow C to be rebased, refuse A, and encourage
+B to be deleted.
+
+To compute (1):
+
+       git-rev-list ^master ^topic next
+       git-rev-list ^master        next
+
+       if these match, topic has not merged in next at all.
+
+To compute (2):
+
+       git-rev-list master..topic
+
+       if this is empty, it is fully merged to "master".
