   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
