Products.PurgeMissingObjectInterfaces 1.0.4a

Warning: This product is highly experimental, and created without deep knowledge/experience of the marker interfaces or ZODB machinery. It may start making modifications deep within the ZODB and interface machinery as soon as it is loaded.

In particular this product was built to remove p4a (Plone 4 Artists) cruft when upgrading from Plone 3 to Plone 4. It should be noted that product has its own uninstallation procedure.
