Kilauea is a minimalistic framework that combines Seaside, Magma and Mewa to help people quickly create web applications with persistence. Currently, the biggest sample app is Nags.
Kilauea has everything you need in its list of MC dependencies, so it should just drop in into an image. Docs are mostly in the Kilauea Howto class, a method to create a new project is in that class' class side.
