Thanks for the quick response.  Unfortunately, I had found the web 
browser thingy (and had to enable javascript for it to work).  :)

I am looking for functions that search for racket functions and return 
racket data structures that describe them.  The key pieces of 
information is the name (so it can be used) and the source location 
(so the implementation can be learned and possibly modified).

Thanks,
Daniel
