+# Based git's git-completion.sh: http://repo.or.cz/w/git/fastimport.git
+# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
+# Distributed under the GNU General Public License, version 2.0.
+#
+# The contained completion routines provide support for completing:
+#
+# *) local and remote branch names
+# *) local and remote tag names
+# *) .git/remotes file names
+# *) git 'subcommands'
+# *) tree paths within 'ref:path/to/file' expressions
+# *) common --long-options
+#
+# To use these routines:
+#
+# 1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
+# 2) Added the following line to your .bashrc:
+# source ~/.git-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.
+#
+# 4) Consider changing your PS1 to also show the current branch:
+# PS1='[\u@\h \W$(__tg_ps1 " (%s)")]\$ '
+#
+# The argument to __tg_ps1 will be displayed only if you
+# are currently in a git repository. The %s token will be
