>>> import bsddb
>>> import os
>>> import time
>>>
>>> db_file = 'native.db'
>>> db = bsddb.db.DB()
>>> db.open(db_file,bsddb.db.DB_UNKNOWN,bsddb.db.DB_RDONLY)
>>> dbs = db.keys()
>>> db.open(db_file,dbs[0],bsddb.db.DB_UNKNOWN,bsddb.db.DB_RDONLY)
>>> db.keys()
['\x01\x00\x00\x00', '\x02\x00\x00\x00', '\x03\x00\x00\x00',
'\x04\x00\x00\x00', '\x05\x00\x00\x00']
