feature request: compile locally?

Would it be possible to add the ability to compile `.coffee` files locally (so that if you have `foo.coffee`, `foo.js` will be created in the same directory, as well as on your CouchDB server)? I'd like to be able to run my javascript locally as well, and for that, `coffee -c .` is a better option than `coffee-script-precompiler`, which is sad.

Thanks!
