# post-update <ref1> <ref2> ...
#
#       This git hook is run by git-receive-pack(1) after applying
#       updates from a client running `git push'.  It receives as
#       arguments all the refs that were updated by the push.
#
#	By the time this hook runs, the updates have been committed to
#	the repository; on failure of this hook, the push is _not_
#	rolled back.
#
#	See the githooks(5) man page for details.
#
# WHAT THIS HOOK IMPLEMENTATION DOES
#
#	If the repository is configured as a one-way git->anoncvs
#	mirror, this hook uses cvsmirror(1) to commit the changes to
#	the CVS mirror so they can be viewed with read-only anoncvs
#	access.  If this is interrupted, cvsmirror(1) will remember the
#	last push that did make it through, so this will pick up where
#	it left off next time.
