[horde] Questions about Rdo and CRUD

[Luis Felipe Marzagao]

Hello:

I took a look at the presentations/riophp2009-application_building 
slides. This has caught my attention:

Building CRUD applications

* Rdo: lightweight ORM with PDO-based and native drivers
* Automatic generation of Model classes
* Override with customized Model
* Automatic generation of Horde_Forms from Model

Is there any [beginner] documentation about this? Is this already working?

Is there any horde module already built with the Rdo approach, so it can 
be used as an example?

Thanks a lot
Luis Felipe
