-# Zulip's post-receive hook.  There is a symlink
-#   from /home/git/repositories/eng/zulip.git/hooks/post-receive
-#   to   ~zulip/zulip/tools/post-receive
-# on git.zulip.net.  So to deploy changes to this script, run
-#
-#   ssh zulip@git.zulip.net 'cd zulip; git pull'
-#
-# To send the Zulip notices, this script calls out to our
-# for-distribution git hook (under api/integrations/); since the git
-# hook needs to be in the same directory as the configuration script
-# for the git hook, this means that we need to have a shared directory
-# containing (a symlink to) both the the for-distribution git hook and
-# the Zulip configuration; for the moment those are
-# bots/githook-post-receive and bots/zulip_git_config.py,
-# respectively.  We need the intermediate symlink because the git hook
-# looks for its configuration in the directory that it sits in, and
-# api/integrations/git/ has the example configuration.
-#
-#
-# The "post-receive" script is run after receive-pack has accepted a pack
-# and the repository has been updated.  It is passed arguments in through
-# stdin in the form
-#  <oldrev> <newrev> <refname>
-# For example:
-#  aa453216d1b3e49e7f6f98441fa56946ddcd6a20 68f7abf4e6f922807889f52bc043ecd31b79f814 refs/heads/master

-# see contrib/hooks/ for a sample
