+       * dak/init_dirs.py: pylint cleanups - long lines, unused globals,
+       docstrings, untabify, don't shadow builtins, lowercase non-global
+       variable names, spaces after commas.  Also bail if given any
+       arguments since we don't accept any.

        * dak/init_db.py (main): check returned value from
        database.get_archive_id().
