Command Line Tool To Supercharge Web Development?

Question

Is there a way to create a command line tool which will help extensively in building an application.

For example, say I have a zend project and I want to add a whole new admin module based on some predefined patterns.

I run:

myzf create admin-module-framework

Which would then setup (as per a predefined template):

The module, models, views, controllers, actions, helpers, plugins, and even create a sql file to go with that.

Of course, I wouldn't be looking for something which simply copies certain files to certain directories (I can do that myself). I'd be looking for something which will actually modify the code to fit in with the app (based on some predefined variables).

Possible? Worth the effort?

Thanks!
