+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
