 SYNOPSIS

 DESCRIPTION

-Use 'git mergetool' to run one of several merge utilities to resolve
-merge conflicts.  It is typically run after gitlink:git-merge[1].
+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.  If no <file> names are
-specified, 'git mergetool' will run the merge tool program on every file
+specified, 'git-mergetool' will run the merge tool program on every file

 	Valid merge tools are:

 You can explicitly provide a full path to the tool by setting the

 can configure the absolute path to kdiff3 by setting
-mergetool.kdiff3.path. Otherwise, 'git mergetool' assumes the tool

+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.
