[Zope] ZODB Imports

I'm reworking a Python application that uses the ZODB stand-alone. I'm running Zope on my system locally and there is a Zodb folder in the installation but the import statements don't work and I cn see that's because the ZODB module no longer exists, at least under that name. Perhaps this is a move from ZODB2 to ZODB3? Anyway, could someone point me in the direction of figuring out how to update the following import statements so they work with the new Zope ZODB stuff? Thanks. import ZODB from Persistence import Persistent from ZODB.PersistentList import PersistentList from ZODB import DB, FileStorage import BTrees from BTrees import OOBTree -- Dan Shafer, Author-Consultant http://www.danshafer.com http://www.shafermedia.com
