# Script:
#   test-masters.sh
#
# Purpose:
#   This script will make sure that any changes on buildbot-configs
#   are valid. The script will call setup-master.py for each master
#   to make sure that they will be able to run 'buildbot checkconfig'.
#   This script defaults to checking 0.7.x masters, and will test
#   0.8.x masters when the -8 switch is passed.
#
# Requirements:
#   You have to have buildbot installed.
#   Include buildbotcustom and tools/lib/python in your PYTHONPATH.
