+#!/bin/sh
+
+# An example hook script to verify what is about to be pushed.
+# Called by "git push" after it has checked the remote status, but before
+# anything has been pushed.  If this script exits with a non-zero status
+# nothing will be pushed.
+#
+# This hook is called with the following parameters:
+#
+# $1 -- Name of the remote to which the push is being done
+# $2 -- URL to which the push is being done
+#
+#   If pushing without using a named remote those arguments will be equal.
+#
+# Further arguments provide information about the commits which are being
+# pushed in the form:
+#
+#   <local ref>:<local sha1>:<remote ref>:<remote sha1>
+#
+# This sample shows how to prevent push of commits where the log
+# message starts with "WIP" (work in progress).
