Coding Style

General formatting

Hard tabs are used for indentation
Spaces are used for alignment (i.e. for the require statement)
Open curly braces are never in their own line
Parentheses are never surrounded by a space on either side, unless in they are used in expressions if the spaces increase the readability
Every statement ends with a semicolon

All require() statements are written in one var statement, i.e. exactly like this:

  var _ = require('underscore'),
      util = require('util'),
      fs = require('fs');
