 From the ZCatalog.Catalog.Catalog docstring:

  "This class is not Zope specific, and can be used in any python
   program to build catalogs of objects.  Note that it does require
   the objects to be Persistent, and thus must be used with ZODB3."


I guess this is not completely true, probably some hacking would be
needed to get it working out of Zope. The IndexedCatalog documentation
says it requires the ZODB too.

Probaly the advantage of ZCatalog is more features and the advantage
of IndexedCatalog is more easy to use without Zope.

Anyway this are good news for me, with IndexedCatalog I see closer
the day I'll get rid of Zope.
