   6 #
   7 # Based git's git-completion.sh: http://repo.or.cz/w/git/fastimport.git
   8 #
   9 # The contained completion routines provide support for completing:
  10 #
  11 #    *) local and remote branch names
  12 #    *) local and remote tag names
  13 #    *) tig 'subcommands'
  14 #    *) tree paths within 'ref:path/to/file' expressions
  15 #
  16 # To use these routines:
  17 #
  18 #    1) Copy this file to somewhere (e.g. ~/.tig-completion.sh).
  19 #    2) Added the following line to your .bashrc:
  20 #        source ~/.tig-completion.sh
  21 #
  22 #    3) You may want to make sure the git executable is available
  23 #       in your PATH before this script is sourced, as some caching
  24 #       is performed while the script loads.  If git isn't found
  25 #       at source time then all lookups will be done on demand,
  26 #       which may be slightly slower.
