# Since it's a pain to manually update the acceptable diffs, this script will pick
# new and modified diffs from the buildbot results, massage them slightly, display
# the difference between the old and new (or the new if no old one) and ask
# whether the diff should be updated.
#
# This script assumes that buildbot log files are available in $bblogdir; this
# will be true only on the buildbot master.
