Extjs: Build and Deploy

So… I have this problem.

I’m trying to integrate Extjs with some kind of building tool, and using SDK tools to build and minify the app. I’m wondering if anyone out in the big world is using this approach? Or maybe you have fallen back into using something else to achieve this?
