   5 # Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
   6 # Distributed under the GNU General Public License, version 2.0.
   7 #
   8 # The contained completion routines provide support for completing:
   9 #
  10 #    *) local and remote branch names
  11 #    *) local and remote tag names
  12 #    *) .git/remotes file names
  13 #    *) git 'subcommands'
  14 #    *) tree paths within 'ref:path/to/file' expressions
  15 #    *) common --long-options
  16 #
  17 # To use these routines:
  18 #
  19 #    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
  20 #    2) Added the following line to your .bashrc:
  21 #        source ~/.git-completion.sh
  22 #
  23 #    3) You may want to make sure the git executable is available
  24 #       in your PATH before this script is sourced, as some caching
  25 #       is performed while the script loads.  If git isn't found
  26 #       at source time then all lookups will be done on demand,
  27 #       which may be slightly slower.
  28 #
  29 #    4) Consider changing your PS1 to also show the current branch:
  30 #        PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
  31 #
  32 #       The argument to __git_ps1 will be displayed only if you
  33 #       are currently in a git repository.  The %s token will be
  34 #       the name of the current branch.
  35 #
  36 # To submit patches:
  37 #
  38 #    *) Read Documentation/SubmittingPatches
  39 #    *) Send all patches to the current maintainer:
  40 #
  41 #       "Shawn O. Pearce" <spearce@spearce.org>
  42 #
  43 #    *) Always CC the Git mailing list:
