+#
+# The contained completion routines provide support for completing:

+#    *) git 'subcommands'
+#    *) tree paths within 'ref:path/to/file' expressions
+#    *) file paths within current working directory and index
+#    *) common --long-options
+#
+# To use these routines:
+#
+#    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
+#    2) Add the following line to your .bashrc/.zshrc:
+#        source ~/.git-completion.sh
+#    3) Consider changing your PS1 to also show the current branch,
+#       see git-prompt.sh for details.
