DBM-style interface to the BSD database library
===============================================

DBM-style interface to the BSD database library.

This manual section was written by Fred L. Drake, Jr. <fdrake@acm.org>.
The `dbhash' module provides a function to open databases using the BSD
`db' library.  This module mirrors the interface of the other Python
database modules that provide access to DBM-style databases.  The
`bsddb'  module is required to use `dbhash'.

This module provides an exception and a function:

`error'
     Exception raised on database errors other than `KeyError'.  It is
     a synonym for `bsddb.error'.

`open(path[, flag[, mode]])'
     Open a `db' database and return the database object.  The PATH
     argument is the name of the database file.

     The FLAG argument can be `'r'' (the default), `'w'', `'c'' (which
     creates the database if it doesn't exist), or `'n'' (which always
     creates a new empty database).  For platforms on which the BSD
     `db' library supports locking, an `l' can be appended to indicate
     that locking should be used.

     The optional MODE parameter is used to indicate the UNIX
     permission bits that should be set if a new database must be
     created; this will be masked by the current umask value for the
     process.
