3# An example hook script to verify what is about to be pushed.  Called by "git
4# push" after it has checked the remote status, but before anything has been
5# pushed.  If this script exits with a non-zero status nothing will be pushed.
6#
7# This hook is called with the following parameters:
8#
9# $1 -- Name of the remote to which the push is being done
10# $2 -- URL to which the push is being done
11#
12# If pushing without using a named remote those arguments will be equal.
13#
14# Information about the commits which are being pushed is supplied as lines to
15# the standard input in the form:
16#
17#   <local ref> <local oid> <remote ref> <remote oid>
18#
19# This sample shows how to prevent push of commits where the log message starts
20# with "WIP" (work in progress).
