+    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.
