JavaScript Cross Reference Tool

I have inherited a fairly large project comprised of HTML and about 20 JavaScript modules.  It would really help if there was a utility out there that can build a cross reference of the JavaScript to ease the pain of getting a handle on them.  It would additionally be nice of the utility or another utility would allow be to cull out the not used functions.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
