-"""A dumb and slow but simple dbm clone.
-
-For database spam, spam.dir contains the index (a text file),
-spam.bak *may* contain a backup of the index (also a text file),
-while spam.dat contains the data (a binary file).
-
-XXX TO DO:
-
-- seems to contain a bug when updating...
-
-- reclaim free space (currently, space once occupied by deleted or expanded
-items is never reused)
-
-- support concurrent access (currently, if two processes take turns making
-updates, they can mess up the index)
-
-- support efficient access to large databases (currently, the whole index
-is read when the database is opened, and some updates rewrite the whole index)
-
-- support opening for read-only (flag = 'm')
