Catalyst::Enzyme is a layer on top of the Catalyst framework providing CRUD functionality for Class::DBI models. Enzyme uses convention and configuration to provide e.g. extensible CRUD out-of-the-box, and a common way of dealing with error handling etc. It's not completely unlike Maypole in this regard. However, at this point Enzyme isn't as feature-rich as Maypole. Enzyme is one way of bringing many Catalyst modules and concepts together into a unified whole. There are other ways to do this (obviously. This is, like... uh, Perl).
