Random snippet to get latest links for GitHub releases.

github-latest-package.js

var username = "github";	// Put username here
var repo = "ruby";			// Put repository name here
/*
That's it! Now use this URL format: 
	
	http://github.com/<username>/<repo>/releases#MyAwesomePackagedApp.zip
	
Where <username> and <repo> are exactly as defined in those variables, and MyAwesomePackagedApp.zip is whatever filename of the ZIP you uploaded in the "releases" page of your repository. 
	
**DOES not work with source code downloads**
