I think I had filed away CGI::Application::Generator for further investigation at one point and then forgot about it. It doesn't seem to be under development anymore.

My module is based on Module::Starter which, though rough around the edges at the moment, seems promising as an extensible framework for generating all sorts of modules. If people like the concept I envision future versions including more elaborate templates which generate entire applications with plugins, multiple runmodes, CRUD—you name it.
