[Zope] Access statistics?

Can anyone recommend a (free) access log stats tool that works nicely with a zope+apache site? I need something that can be configured to view stats per user ID, so we can see who downloaded what when. -- Paul Winkler http://www.slinkp.com Look! Up in the sky! It's ROTISSERIE FAT LORD!
