+NAME
+----
+git-difftool - Show changes using common diff tools
+
+SYNOPSIS
+--------
+'git difftool' [--tool=<tool>] [-y|--no-prompt|--prompt] [<'git diff' options>]
+
+DESCRIPTION
+-----------
+'git-difftool' is a git command that allows you to compare and edit files
+between revisions using common diff tools. 'git difftool' is a frontend
+to 'git-diff' and accepts the same options and arguments.
+
+OPTIONS
+-------
+-y::
+--no-prompt::
+ Do not prompt before launching a diff tool.
+
+--prompt::
+ Prompt before each invocation of the diff tool.
+ This is the default behaviour; the option is provided to
+ override any configuration settings.
+
+-t <tool>::
+--tool=<tool>::
+ Use the diff tool specified by <tool>.
+ Valid merge tools are:
+ kdiff3, kompare, tkdiff, meld, xxdiff, emerge, vimdiff, gvimdiff,
+ ecmerge, diffuse and opendiff
++
+If a diff tool is not specified, 'git-difftool'
+will use the configuration variable `diff.tool`. If the
+configuration variable `diff.tool` is not set, 'git-difftool'
+will pick a suitable default.
++
+You can explicitly provide a full path to the tool by setting the
+configuration variable `difftool.<tool>.path`. For example, you
+can configure the absolute path to kdiff3 by setting
+`difftool.kdiff3.path`. Otherwise, 'git-difftool' assumes the
+tool is available in PATH.
++
+Instead of running one of the known diff tools,
+'git-difftool' can be customized to run an alternative program
+by specifying the command line to invoke in a configuration
+variable `difftool.<tool>.cmd`.
++
+When 'git-difftool' is invoked with this tool (either through the
+`-t` or `--tool` option or the `diff.tool` configuration variable)
+the configured command line will be invoked with the following
+variables available: `$LOCAL` is set to the name of the temporary
+file containing the contents of the diff pre-image and `$REMOTE`
+is set to the name of the temporary file containing the contents
+of the diff post-image. `$BASE` is provided for compatibility
+with custom merge tool commands and has the same value as `$LOCAL`.
+
+See linkgit:git-diff[1] for the full list of supported options.
+
+CONFIG VARIABLES
+----------------
+'git-difftool' falls back to 'git-mergetool' config variables when the
+difftool equivalents have not been defined.
+
+diff.tool::
+ The default diff tool to use.
+
+difftool.<tool>.path::
+ Override the path for the given tool. This is useful in case
+ your tool is not in the PATH.
+
+difftool.<tool>.cmd::
+ Specify the command to invoke the specified diff tool.
++
+See the `--tool=<tool>` option above for more details.
+
+difftool.prompt::
+ Prompt before each invocation of the diff tool.
+
+SEE ALSO
+--------
+linkgit:git-diff[1]::
+ Show changes between commits, commit and working tree, etc
+
+linkgit:git-mergetool[1]::
+ Run merge conflict resolution tools to resolve merge conflicts
+
+linkgit:git-config[1]::
+ Get and set repository or global options

useful in the future for compensating for some git bugs or such,
therefore such a usage is permitted.

refname::
The name of the ref (the part after $GIT_DIR/).
For a non-ambiguous short name of the ref append `:short`.
+ The option core.warnAmbiguousRefs is used to select the strict
+ abbreviation mode.
objecttype::
The type of the object (`blob`, `tree`, `commit`, `tag`).
objectname::
The object name (aka SHA-1).
+upstream::
+ The name of a local ref which can be considered ``upstream''
+ from the displayed ref. Respects `:short` in the same way as
+ `refname` above.
+
In addition to the above, for commit and tag objects, the header
field names (`tree`, `parent`, `object`, `type`, and `tag`) can
be used to specify the value in the header field.

+=====================
+
+NAME
+----
+git-mergetool--lib - Common git merge tool shell scriptlets
+
+SYNOPSIS
+--------
+'TOOL_MODE=(diff|merge) . "$(git --exec-path)/git-mergetool--lib"'
+
+DESCRIPTION
+-----------
+
+This is not a command the end user would want to run. Ever.
+This documentation is meant for people who are studying the
+Porcelain-ish scripts and/or are writing new ones.
+
+The 'git-mergetool--lib' scriptlet is designed to be sourced (using
+`.`) by other shell scripts to set up functions for working
+with git merge tools.
+
+Before sourcing 'git-mergetool--lib', your script must set `TOOL_MODE`
+to define the operation mode for the functions listed below.
+'diff' and 'merge' are valid values.
+
+FUNCTIONS
+---------
+get_merge_tool::
+ returns a merge tool.
+
+get_merge_tool_cmd::
+ returns the custom command for a merge tool.
+
+get_merge_tool_path::
+ returns the custom path for a merge tool.
+
+run_merge_tool::
+ launches a merge tool given the tool name and a true/false
+ flag to indicate whether a merge base is present.
+ '$MERGED', '$LOCAL', '$REMOTE', and '$BASE' must be defined
+ for use by the merge tool.

-NAME
-----
-git-difftool - compare changes using common merge tools
-
-SYNOPSIS
---------
-'git difftool' [--tool=<tool>] [--no-prompt] ['git diff' options]
-
-DESCRIPTION
------------
-'git-difftool' is a git command that allows you to compare and edit files
-between revisions using common merge tools. At its most basic level,
-'git-difftool' does what 'git-mergetool' does but its use is for non-merge
-situations such as when preparing commits or comparing changes against
-the index.
-
-'git difftool' is a frontend to 'git diff' and accepts the same
-arguments and options.
-
-See linkgit:git-diff[1] for the full list of supported options.
-
-OPTIONS
--------
--t <tool>::
---tool=<tool>::
- Use the merge resolution program specified by <tool>.
- Valid merge tools are:
- kdiff3, kompare, tkdiff, meld, xxdiff, emerge,
- vimdiff, gvimdiff, ecmerge, and opendiff
-+
-If a merge resolution program is not specified, 'git-difftool'
-will use the configuration variable `diff.tool`. If the
-configuration variable `diff.tool` is not set, 'git-difftool'
-will pick a suitable default.
-+
-You can explicitly provide a full path to the tool by setting the
-configuration variable `difftool.<tool>.path`. For example, you
-can configure the absolute path to kdiff3 by setting
-`difftool.kdiff3.path`. Otherwise, 'git-difftool' assumes the
-tool is available in PATH.
-+
-Instead of running one of the known merge tool programs,
-'git-difftool' can be customized to run an alternative program
-by specifying the command line to invoke in a configuration
-variable `difftool.<tool>.cmd`.
-+
-When 'git-difftool' is invoked with this tool (either through the
-`-t` or `--tool` option or the `diff.tool` configuration variable)
-the configured command line will be invoked with the following
-variables available: `$LOCAL` is set to the name of the temporary
-file containing the contents of the diff pre-image and `$REMOTE`
-is set to the name of the temporary file containing the contents
-of the diff post-image. `$BASE` is provided for compatibility
-with custom merge tool commands and has the same value as `$LOCAL`.
-
---no-prompt::
- Do not prompt before launching a diff tool.
-
-CONFIG VARIABLES
-----------------
-'git-difftool' falls back to 'git-mergetool' config variables when the
-difftool equivalents have not been defined.
-
-diff.tool::
- The default merge tool to use.
-
-difftool.<tool>.path::
- Override the path for the given tool. This is useful in case
- your tool is not in the PATH.
-
-difftool.<tool>.cmd::
- Specify the command to invoke the specified merge tool.
-+
-See the `--tool=<tool>` option above for more details.
-
-merge.keepBackup::
- The original, unedited file content can be saved to a file with
- a `.orig` extension. Defaults to `true` (i.e. keep the backup files).
-
-SEE ALSO
---------
-linkgit:git-diff[1]::
- Show changes between commits, commit and working tree, etc
-
-linkgit:git-mergetool[1]::
- Run merge conflict resolution tools to resolve merge conflicts
-
-linkgit:git-config[1]::
- Get and set repository or global options
