Separate sections on anydbm and dumbdbm.

Browse source 
This is the last separation; each module now gets its own section.  This will
be useful in performing conversions.

\module{anydbm} is a generic interface to variants of the DBM
database--DBM, GDBM, or dbhash. If none of these modules is
installed, the slow-but-simple implementation in module \module{dumbdbm}
will be used. Both modules provide the same interface:
database --- \module{dbhash}\refbimodindex{dbhash},
\module{gdbm}\refbimodindex{gdbm}, or \module{dbm}\refbimodindex{dbm}.
If none of these modules is installed, the slow-but-simple
implementation in module \module{dumbdbm}\refstmodindex{dumbdbm} will
be used.

The object returned by \function{open()} supports most of the same

be stored, retrieved, and deleted, and the \method{has_key()} and
\method{keys()} methods are available. Keys and values must always be
strings.
Both modules also export the exception \exception{error}, which is
raised for various problems. The \exception{anydbm.error} exception
is simply a different name for the \exception{error} exception of the
underlying implementation module used.

A simple and slow database implemented entirely in Python. This

Open the database file \var{filename} and return a corresponding object.
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
specified, the default value is \code{'r'}.
