+# This hook does two things:
+#
+#  1. update the "info" files that allow the list of references to be
+#     queries over dumb transports such as http
+#
+#  2. if this repository looks like it is a non-bare repository, and
+#     the checked-out branch is pushed to, then update the working copy.
+#     This makes "push" function somewhat similarly to darcs and bzr.
+#
+# To enable this hook, make this file executable by "chmod +x post-update".
