# This script is a utility script for use by LukeShu during the
# migration to per-product/version subtrees.  It isn't something that
# is meant to be run during normal work.  If you would like to run
# this script, and therefore would like to be involved in that
# migration, then you should probably have a chat involving Luke about
# the migration plan.
