Anyone using RailsProductGenerator ?

I need a solution provides a:

"first tier ... single base application that encapsulates common
functionality for your product. The second tier consists of several
customized applications that inherit and extend functionality from that
base. It is useful for web developers who want to create a base
application with some sort of generic functionality (e.g. a shopping
cart) and then extend or modify that functionality for specific clients
only." (

RailsProductGenerator looks ideal for this?

Has anyone used it recently? Does it work with Rails 2.0?

Are there any other alternatives I should consider?

Thank you,
