By the way, this requires Ember master as of 1/13.

Oh, and a special thanks to @tchak for helping me figure this out!

@garth

I'm guessing that we should be able to replace Assetfile.rb with some equivalent js and run this through nodejs?

@garth, in theory yes. The main thing is that you have to have a full Ember running to get proper compilation. Unforunately, right now that requires stubbing some things out like in my headless-ember.js.

@manoharank

@wagenet I am getting error when compiling ember 1.0.0-pre.4 in this line https://github.com/emberjs/ember.js/blob/master/packages/ember-views/lib/system/utils.js#L24. Any workaround?
