-The optional \var{flag} argument can be
-\code{'r'} to open an existing database for reading only,
-\code{'w'} to open an existing database for reading and writing,
-\code{'c'} to create the database if it doesn't exist, or
-\code{'n'}, which will always create a new empty database.  If not

-\code{0666} (and will be modified by the prevailing umask).
