+NAME
+----
+git-difftool - Show changes using common diff tools
+
+SYNOPSIS
+--------
+[verse]
+'git difftool' [<options>] [<commit> [<commit>]] [--] [<path>...]
+
+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. See
+linkgit:git-diff[1].
+
+OPTIONS
+-------
+-d::
+--dir-diff::
+ Copy the modified files to a temporary location and perform
+ a directory diff on them. This mode never prompts before
+ launching the diff tool.
+
+-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.
+
+--rotate-to=<file>::
+ Start showing the diff for the given path,
+ the paths before it will move to end and output.
+
+--skip-to=<file>::
+ Start showing the diff for the given path, skipping all
+ the paths before it.
+
+-t <tool>::
+--tool=<tool>::
+ Use the diff tool specified by <tool>. Valid values include
+ emerge, kompare, meld, and vimdiff. Run `git difftool --tool-help`
+ for the list of valid <tool> settings.
++
+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. `$MERGED` is the name of the file which is
+being compared. `$BASE` is provided for compatibility
+with custom merge tool commands and has the same value as `$MERGED`.
+
+--tool-help::
+ Print a list of diff tools that may be used with `--tool`.
+
+--[no-]symlinks::
+ 'git difftool''s default behavior is create symlinks to the
+ working tree when run in `--dir-diff` mode and the right-hand
+ side of the comparison yields the same content as the file in
+ the working tree.
++
+Specifying `--no-symlinks` instructs 'git difftool' to create copies
+instead. `--no-symlinks` is the default on Windows.
+
+-x <command>::
+--extcmd=<command>::
+ Specify a custom command for viewing diffs.
+ 'git-difftool' ignores the configured defaults and runs
+ `$command $LOCAL $REMOTE` when this option is specified.
+ Additionally, `$BASE` is set in the environment.
+
+-g::
+--[no-]gui::
+ When 'git-difftool' is invoked with the `-g` or `--gui` option
+ the default diff tool will be read from the configured
+ `diff.guitool` variable instead of `diff.tool`. The `--no-gui`
+ option can be used to override this setting. If `diff.guitool`
+ is not set, we will fallback in the order of `merge.guitool`,
+ `diff.tool`, `merge.tool` until a tool is found.
+
+--[no-]trust-exit-code::
+ 'git-difftool' invokes a diff tool individually on each file.
+ Errors reported by the diff tool are ignored by default.
+ Use `--trust-exit-code` to make 'git-difftool' exit when an
+ invoked diff tool returns a non-zero exit code.
++
+'git-difftool' will forward the exit code of the invoked tool when
+`--trust-exit-code` is used.
+
+See linkgit:git-diff[1] for the full list of supported options.
+
+CONFIGURATION
+-------------
+'git difftool' falls back to 'git mergetool' config variables when the
+difftool equivalents have not been defined.
