   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 sha1> <remote ref> <remote sha1>
  18#
  19# This sample shows how to prevent push of commits where the log message starts
  20# with "WIP" (work in progress).
