# A 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.
# Information about the commits which are being pushed is supplied as lines to
# the standard input in the form:
# <local ref> <local sha1> <remote ref> <remote sha1>
# Only care about the upstream repositories
