+Git v1.6.6.2 Release Notes
+==========================
+
+Fixes since v1.6.6.1
+--------------------
+
+ * recursive merge didn't correctly diagnose its own programming errors,
+   and instead caused the caller to segfault.
+
+ * The new "smart http" aware clients probed the web servers to see if
+   they support smart http, but did not fall back to dumb http transport
+   correctly with some servers.
+
+ * Time based reflog syntax e.g. "@{yesterday}" didn't diagnose a misspelled
+   time specification and instead assumed "@{now}".
+
+ * "git archive HEAD -- no-such-directory" produced an empty archive
+   without complaining.
+
+ * "git blame -L start,end -- file" misbehaved when given a start that is
+   larger than the number of lines in the file.
+
+ * "git checkout -m" didn't correctly call custom merge backend supplied
+   by the end user.
+
+ * "git config -f <file>" misbehaved when run from a subdirectory.
+
+ * "git cvsserver" didn't like having regex metacharacters (e.g. '+') in
+   CVSROOT environment.
+
+ * "git fast-import" did not correctly handle large blobs that may
+   bust the pack size limit.
+
+ * "git gui" is supposed to work even when launched from inside a .git
+   directory.
+
+ * "git gui" misbehaved when applying a hunk that ends with deletion.
+

-HOW MERGE WORKS
----------------
-
-A merge is always between the current `HEAD` and one or more
-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 invoked from 'git pull':
-  you are tracking an upstream repository, have committed no local
-  changes and now you want to update to a newer upstream revision.
-  Your `HEAD` (and the index) is updated to point at 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 both of them 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.
-When things merge cleanly, this is what happens:
-
-1. The results are updated both in the index file and in your
-   working tree;
-2. Index file is written out as a tree;
-3. The tree gets committed; and
-4. The `HEAD` pointer gets advanced.
-
-Because of 2., we require that the original state of the index
-file matches exactly the current `HEAD` commit; otherwise we
-will write out your local changes already registered in your
-index file along with the merge result, which is not good.
-Because 1. involves only those paths differing between your
-branch and the branch you are merging
-(which is typically a fraction of the whole tree), you can
-have local modifications in your working tree as long as they do
-not overlap with what the merge updates.
-
-When there are conflicts, the following happens:
-
-1. `HEAD` stays the same.
-
-2. Cleanly merged paths are updated both in the index file and
-   in your working tree.
+FAST-FORWARD MERGE
+------------------
+
+Often the current branch head is an ancestor of the named commit.
+This is the most common case especially when invoked from 'git
+pull': you are tracking an upstream repository, you have committed
+no local changes, and now you want to update to a newer upstream
+revision.  In this case, a new commit is not needed to store the
+combined history; instead, the `HEAD` (along with the index) is
+updated to point at the named commit, without creating an extra
+merge commit.
+
+This behavior can be suppressed with the `--no-ff` option.
 
-3. For conflicting paths, the index file records up to three
-   versions; stage1 stores the version from the common ancestor,
-   stage2 from `HEAD`, and stage3 from the other branch (you
+TRUE MERGE
+----------
+
+Except in a fast-forward merge (see above), the branches to be
+merged must be tied together by a merge commit that has both of them
+as its parents.
+
+A merged version reconciling the changes from all branches to be
+merged is committed, and your `HEAD`, index, and working tree are
+updated to it.  It is possible to have modifications in the working
+tree as long as they do not overlap; the update will preserve them.
+
+When it is not obvious how to reconcile the changes, the following
+happens:
+
+1. The `HEAD` pointer stays the same.
+2. The `MERGE_HEAD` ref is set to point to the other branch head.
+3. Paths that merged cleanly are updated both in the index file and
+   in your working tree.
+4. For conflicting paths, the index file records up to three
+   versions: stage 1 stores the version from the common ancestor,
+   stage 2 from `HEAD`, and stage 3 from `MERGE_HEAD` (you
    can inspect the stages with `git ls-files -u`).  The working
    tree files contain the result of the "merge" program; i.e. 3-way
-   merge results with familiar conflict markers `<<< === >>>`.
-
-4. No other changes are done.  In particular, the local
+   merge results with familiar conflict markers `<<<` `===` `>>>`.
+5. No other changes are made.  In particular, the local
    modifications you had before you started merge will stay the
    same and the index entries for them stay as they were,
    i.e. matching `HEAD`.
 
+If you tried a merge which resulted in complex conflicts and
+want to start over, you can recover with `git reset --merge`.

- * Check-out files from the "current cache directory"
- *
- * Copyright (C) 2005 Linus Torvalds
- *
- * Careful: order of argument flags does matter. For example,
- *
- *     git checkout-index -a -f file.c
- *
- * Will first check out all files listed in the cache (but not
- * overwrite any old ones), and then force-checkout "file.c" a
- * second time (ie that one _will_ overwrite any old contents
- * with the same filename).
- *
- * Also, just doing "git checkout-index" does nothing. You probably
- * meant "git checkout-index -a". And if you want to force it, you
- * want "git checkout-index -f -a".
- *
- * Intuitiveness is not the goal here. Repeatability is. The
- * reason for the "no arguments means no work" thing is that
- * from scripts you are supposed to be able to do things like
- *
- *     find . -name '*.h' -print0 | xargs -0 git checkout-index -f --
- *
- * or:
- *
- *     find . -name '*.h' -print0 | git checkout-index -f -z --stdin
- *
- * which will force all existing *.h files to be replaced with
- * their cached copies. If an empty command line implied "all",
- * then this would force-refresh everything in the cache, which
- * was not the point.
- *
- * Oh, and the "--" is just a good idea when you know the rest
- * will be filenames. Just so that you wouldn't have a filename
- * of "-a" causing problems (not possible in the above example,
- * but get used to it in scripting!).

+ *

+ * with the same filename).
+ *
+ * Also, just doing "git checkout-index" does nothing. You probably
+ * meant "git checkout-index -a". And if you want to force it, you
+ * want "git checkout-index -f -a".
+ *
+ * Intuitiveness is not the goal here. Repeatability is. The

+ *
+ * Oh, and the "--" is just a good idea when you know the rest
+ * will be filenames. Just so that you wouldn't have a filename

+----------------------------------------------------
+
+If you want to use gitweb with several project roots you can edit your apache
+virtual host and gitweb.conf configuration files like this :
+
+virtual host configuration :
+
+<VirtualHost *:80>
+    ServerName                 git.example.org
+    DocumentRoot               /pub/git
+    SetEnv                             GITWEB_CONFIG   /etc/gitweb.conf
+
+    # turning on mod rewrite
+    RewriteEngine on

+    RewriteRule ^/$            /cgi-bin/gitweb.cgi [QSA,L,PT]

+</VirtualHost>
+
+gitweb.conf configuration :
+
+$projectroot = $ENV{'GITWEB_PROJECTROOT'} || "/pub/git";
+
+These configurations enable two things. First, each unix user (<user>) of the
+server will be able to browse through gitweb git repositories found in
+~/public_git/ with the following url : http://git.example.org/~<user>/
+
+If you do not want this feature on your server just remove the second rewrite rule.
+
+If you already use mod_userdir in your virtual host or you don't want to use
+the '~' as first character just comment or remove the second rewrite rule and
+uncomment one of the following according to what you want.
+
+Second, repositories found in /pub/scm/ and /var/git/ will be accesible
+through http://git.example.org/scm/ and http://git.example.org/var/.
+You can add as many project roots as you want by adding rewrite rules like the
+third and the fourth.
