build-scripts/git-pre-push-hook.pl

#!/usr/bin/perl -w

# To use this script: symlink it to .git/hooks/pre-push, then "git push"
#
# This script is 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>
