Using Git to Manage a Live Web Site

Overview

As a freelancer, I build a lot of web sites. That's a lot of code changes to track. Thankfully, a Git-enabled workflow with proper branching makes short work of project tracking. I can easily see development features in branches as well as a snapshot of the sites' production code. A nice addition to that workflow is that ability to use Git to push updates to any of the various sites I work on while committing changes.

	function f() {

	var character = t.shift();
	var i=[];
	var code = character.charCodeAt();
	var needs_shift = "!@#$%^&*()_+{}:\"<>?~\|".indexOf(character) !== -1
