// Using this script with : : :::::::::::::::::::::::::::::::::
/* Selected Script Id is determined below
	
	YOU MUST FIRST HAVE A USERSCRIPT.ORG PROFILE AND UPLOADED THE SCRIPT ONCE
	
	Projects & Forks (github.com/user_name/project_name/)
		
		Add the URL to your script on userscripts.org to the README file 
		for the branch.  This is the URL format we need:
		
		 http://userscripts.org/scripts/show/99999
		 
		Then the link to install any user.js files will show up.
		
		Has the added convenience of directing users to install your script!
		
		if you add the URL to your script, it will work on other pages instead
		 
	Gists (gist.github.com)
		
		Visit the gist you want to install.  The description OR
		The body of the script should contain the URL to the script
		
		 http://userscripts.org/scripts/show/99999

		Click the install button to transfer the script to UserScripts.org
		
	Branches: coming soon?
