openAnyDBM :: FilePath -> PyDBMOpenFlags -> IO PyDict

Opens a persistent storage database using the "best" storage mechanism available to Python on this system. This will usually be one of the *dbm services, though in rare circumstances, could be "dumbdbm", which is only marginally better than Database.AnyDBM.StringDBM.
