Edit File: post-receive-cinotify

#!/usr/bin/perl
#
# A hook that notifies its companion cidaemon through a simple
# queue file that a ref has been updated via a push (actually
# by a receive-pack running on the server).
#
# See cidaemon for per-repository configuration details.
#
# To use this hook, add it as the post-receive hook, make it
# executable, and set its configuration options.
