+# 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, or uncomment the next line and
+# rename the file to "post-receive".
