   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
