2# bash completion support for core Git.
3#
4# Copyright (C) 2006 Shawn Pearce
5# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
6#
7# The contained completion routines provide support for completing:
8#
9# *) local and remote branch names
10# *) local and remote tag names
11# *) .git/remotes file names
12# *) git 'subcommands'
13# *) tree paths within 'ref:path/to/file' expressions
14#
15# To use these routines:
16#
17# 1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
18# 2) Added the following line to your .bashrc:
19# source ~/.git-completion.sh
20#
