+NAME
+----
+git-mergetool - Run merge conflict resolution tools to resolve merge conflicts
+
+SYNOPSIS
+--------
+[verse]
+'git mergetool' [--tool=<tool>] [-y | --[no-]prompt] [<file>...]
+
+DESCRIPTION
+-----------
+
+Use `git mergetool` to run one of several merge utilities to resolve
+merge conflicts. It is typically run after 'git merge'.
+
+If one or more <file> parameters are given, the merge tool program will
+be run to resolve differences on each file (skipping those without
+conflicts). Specifying a directory will include all unresolved files in
+that path. If no <file> names are specified, 'git mergetool' will run
+the merge tool program on every file with merge conflicts.
+
+OPTIONS
+-------
+-t <tool>::
+--tool=<tool>::
+ Use the merge resolution program specified by <tool>.
+ Valid values include emerge, gvimdiff, kdiff3,
+ meld, vimdiff, and tortoisemerge. Run `git mergetool --tool-help`
+ for the list of valid <tool> settings.
++
+If a merge resolution program is not specified, 'git mergetool'
+will use the configuration variable `merge.tool`. If the
+configuration variable `merge.tool` is not set, 'git mergetool'
+will pick a suitable default.
++
+You can explicitly provide a full path to the tool by setting the
+configuration variable `mergetool.<tool>.path`. For example, you
+can configure the absolute path to kdiff3 by setting
+`mergetool.kdiff3.path`. Otherwise, 'git mergetool' assumes the
+tool is available in PATH.
++
+Instead of running one of the known merge tool programs,
+'git mergetool' can be customized to run an alternative program
+by specifying the command line to invoke in a configuration
+variable `mergetool.<tool>.cmd`.
++
+When 'git mergetool' is invoked with this tool (either through the
+`-t` or `--tool` option or the `merge.tool` configuration
+variable) the configured command line will be invoked with `$BASE`
+set to the name of a temporary file containing the common base for
+the merge, if available; `$LOCAL` set to the name of a temporary
+file containing the contents of the file on the current branch;
+`$REMOTE` set to the name of a temporary file containing the
+contents of the file to be merged, and `$MERGED` set to the name
+of the file to which the merge tool should write the result of the
+merge resolution.
++
+If the custom merge tool correctly indicates the success of a
+merge resolution with its exit code, then the configuration
+variable `mergetool.<tool>.trustExitCode` can be set to `true`.
+Otherwise, 'git mergetool' will prompt the user to indicate the
+success of the resolution after the custom tool has exited.
+
+--tool-help::
+ Print a list of merge tools that may be used with `--tool`.
+
+-y::
+--no-prompt::
+ Don't prompt before each invocation of the merge resolution
+ program.
+ This is the default if the merge resolution program is
+ explicitly specified with the `--tool` option or with the
+ `merge.tool` configuration variable.
+
+--prompt::
+ Prompt before each invocation of the merge resolution program
+ to give the user a chance to skip the path.
+
+-g::
+--gui::
+ When 'git-mergetool' is invoked with the `-g` or `--gui` option
+ the default merge tool will be read from the configured
+ `merge.guitool` variable instead of `merge.tool`. If
+ `merge.guitool` is not set, we will fallback to the tool
+ configured under `merge.tool`.
+
+--no-gui::
+ This overrides a previous `-g` or `--gui` setting and reads the
+ default merge tool will be read from the configured `merge.tool`
+ variable.
+
+-O<orderfile>::
+ Process files in the order specified in the
+ <orderfile>, which has one shell glob pattern per line.
+ This overrides the `diff.orderFile` configuration variable
+ (see linkgit:git-config[1]). To cancel `diff.orderFile`,
+ use `-O/dev/null`.
+
+TEMPORARY FILES
+---------------
+`git mergetool` creates `*.orig` backup files while resolving merges.
+These are safe to remove once a file has been merged and its
+`git mergetool` session has completed.
+
+Setting the `mergetool.keepBackup` configuration variable to `false`
+causes `git mergetool` to automatically remove the backup as files
+are successfully merged.
