# Clean up hashes from Blends metadata importer
# ---------------------------------------------
# The Blends metadata importer stores hashes for every single tasks
# file in UDD to speed up the import drastically by making sure
# that old data are not importet again and again for no use.
# Sometimes (basically for development / debuging) it is needed
# to do the reimport and thus cleaning up the hashes to force a new
# import is needed.  This can be done with this script.
# If 'all' as argument is given all Blends are cleaned up.
