WordPress.org

This framework is a collection of classes and functions for handling advanced custom post types cases. With just a few defined arrays, it can create custom post types, taxonomies, their labels, menus, metaboxes, and save routines.

NOTE: this began life as an internal development tool, and as such, does not have much (if any documentation) just yet. It's not really end-user friendly in its current state. So if you're not running a site I have built for you personally, you probably don't need it ;-)
