    CoffeeScript is a little language that compiles into JavaScript. Think
    of it as JavaScript's less ostentatious kid brother -- the same genes,
    roughly the same height, but a different sense of style. Apart from a
    handful of bonus goodies, statements in CoffeeScript correspond
    one-to-one with their equivalent in JavaScript, it's just another
    way of saying it.

Add package.json to gemspec files so Narwhal integrations works when installed as a gem.
