mogenerator: Core Data codegen:

Core Data, like its Enterprise Objects Framework (EOF) ancestor, offers to represent your persistent object instances as classes of a generic data class (NSManagedObject in Core Data, EOGenericRecord in EOF) or a custom subclass of the generic class.

This looks to be the beginning of a great tool for those of us who are getting quickly addicted to the the Core Data stuff
