## NAME

## 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.
