+# bash completion support for tig
+#
+# Copyright (C) 2007 Jonas fonseca
+# Copyright (C) 2006,2007 Shawn Pearce
+#
+# Based git's git-completion.sh: http://repo.or.cz/w/git/fastimport.git
+#
+# The contained completion routines provide support for completing:
+#
+#    *) local and remote branch names
+#    *) local and remote tag names
+#    *) tig 'subcommands'
+#    *) tree paths within 'ref:path/to/file' expressions
+#
+# To use these routines:
+#
+#    1) Copy this file to somewhere (e.g. ~/.tig-completion.sh).
+#    2) Added the following line to your .bashrc:
+#        source ~/.tig-completion.sh
+#
+#    3) You may want to make sure the git executable is available
+#       in your PATH before this script is sourced, as some caching
+#       is performed while the script loads.  If git isn't found
+#       at source time then all lookups will be done on demand,
+#       which may be slightly slower.
