1# **CoffeeCup** lets you to write HTML templates in 100% pure
2# [CoffeeScript](http://coffeescript.org).
3#
4# You can run it on [node.js](http://nodejs.org) or the browser, or compile your
5# templates down to self-contained javascript functions, that will take in data
6# and options and return generated HTML on any JS runtime.
7#
8# The concept is directly stolen from the amazing
9# [Markaby](http://markaby.rubyforge.org/) by Tim Fletcher and why the lucky
