ExtJs dependency management using RequireJS, LABjs (or similar)

I am trying to find examples of how to wrap ExtJs and ExtJs 'modules' up for use with a javascript dependency framework such as RequireJS or LAB.

I am working with a large ExtJs based project and there are many separate module files which are just bulk included everywhere and it is getting a little out of control.

Has anyon开发者_如何学Goe used an existing depenency management framework with ExtJs? (I know ExtJs 4 may include something similar, but I am fixed on using ExtJs 3)

I wrote my own dependency utility (well my boss wrote it as a method for another framework we are building, and I just ported it to ExtJS) as a mixin where you can just define what your dependencies are, and include events for when they are loaded.

Using Grunt https://github.com/mattgoldspink/grunt-sencha-dependencies

Sencha Cmd now does it automatically as well - unfortunately it considers ExtJS4.1 as legacy, let alone 3.
