Commit regression script. The cron job uses a copy in m5test's
home directory (/z/m5/regression), so for now any modifications should be manually copied there as well. Note that this script is designed to be useful for running full regressions outside of the cron job as well. --HG-- extra : convert_revision : 052ec5d58b5ff765d8f3a9b50849ef34d62c8d66
