But perhaps I got Rails confused with Ruby with my brief experience with it. I thought Rails provided the tools to auto-create your project structure in an MVC style.
If you use something like Catalyst of CGI::Application you get built in things like MVC project structure, auto populate a 'class' from a table entry, etc.
Basically, you get all those built-in functionality for building web apps that you would in Rails. But, I very briefly played with Rails, so I may have its definition confused.
