	NONTRIVIAL THINGS:

	JAVASCRIPT CAN BE FOUND IN:
	- Event handlers (onclick, onload, onsubmit, etc.)
	- <script>JS</script>
	- <script src="/JS.js"></script>
	WAYS TO DETERMINE PASS/FAIL:
	- "// @license [magnet link] [identifier]" then "// @license-end" (may also use /* comments)
	- Automatic whitelist: (http://bzr.savannah.gnu.org/lh/librejs/dev/annotate/head:/data/script_libraries/script-libraries.json_
	- <table id="jslicense-labels1"><table> which may be linked to by a link tag identified by rel="jslicense" or data-jslicense="1"
	- In the first script tag, declare the license with @licstart/@licend
