Looks awesome. I'll certainly be putting this to some use :)

That said.

> Anyway, they all require Node.js, a huge dependency for this simple problem, in my opinion.

While I personally agree with this opinion, isn't it typically the case that a frontend dev's workflow already heavily relies on Node? It's probably already installed for all that Wangular.js nonsense, so it being tacked on to one of the heavier CSS preprocessors probably doesn't make much of a difference, no?
