	 Hacked on and probably mangled by Ed Cramer, summer 2010
	 captthud@captthud.net
	 
	 I want to track PDF downloads with this, but I don't want to use the actual path of the PDF file
	 for my statistics. I'd like the script to post information about the parent page that the user
	 found the PDF on. 
	 
	 The original code used the "traditional" tracking code snippet, and I'd prefer the "asyncrhonous"
	 code because it's supposed to be faster. I've changed a lot of the formatting and I think
	 I've removed the bug fix for IE6/7.
	 
	 Put  
		<script type="text/javascript" src="/path_to_the_script/addLinkerEvents-ga.js"></script>
	in your header and then call
		<script> addLinkerEvents(); </script>
	at the end of the html body. Browser debuggers (Firebug, dev tools in Chrome and IE) are amazing, use them!
