NAME
       git-mergetool--lib - Common Git merge tool shell scriptlets

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.

FUNCTIONS
       get_merge_tool
	   Returns a merge tool. The return code is 1 if we returned a guessed
	   merge tool, else 0.	$GIT_MERGETOOL_GUI may be set to true to
	   search for the appropriate guitool.

       get_merge_tool_cmd
	   Returns the custom command for a merge tool.

       get_merge_tool_path
	   Returns the custom path for a merge tool.

       initialize_merge_tool
	   Brings merge tool specific functions into scope so they can be used
	   or overridden.

       run_merge_tool
	   Launches a merge tool given the tool name and a true/false flag to
	   indicate whether a merge base is present.  $MERGED, $LOCAL,
	   $REMOTE, and $BASE must be defined for use by the merge tool.
