Functions
		open(filename, flags=1, mode=432, filetype=2, dbenv=None, dbname=None) A simple factory function for compatibility with the standard shleve.py module.  It can be used like this, where key is a string and data is a pickleable object:       from bsddb import dbshelve     db = dbshelve.open(filename)       db[key] = data       db.close()
