AuthoRails is a framework for generating authorizations,tables,relations,scaffolds and privileges.

A "Productized Rails Application" is a single generic application having a hierarchical structure wherein add-ons and tweaks for concurrent versions of the application are possible without affecting the core "generic" code base. You might use this, for example, if you want to maintain a common shopping cart code base that all of your clients use, while still providing flexibility for paid add-ons or site-specific needs.
