I am looking to nest an include for one javascript file in another, how do I do this?

you don't.

document.write('<script src="script2.js"></script>');

?

or, in a more "programming" way of doing:

js=document.createElement('script')
js.type="text/javascript"
js.src="http://whatever.com/included.js"
document.getElementsByTagName['body'][0].appendChild(js)
