[Zope] Finding old revisions, from an OID

Given an OID for an object in the zodb, can I ... - find out what revisions are still in the zodb? - find out what transactions modified this object? I think I can do it by using utilities/ZODBTools/fsdump.py and grepping the output. Is there an easier way? -- Paul Winkler http://www.slinkp.com Look! Up in the sky! It's QUASI GUZZLING DOG!
