Arthur:  Thank you for this.

Yes.  This is a little bit thorny.  However, I'm confident that the 
hyperlinks will be useful even if some of them are broken, and so I this 
I'm inclined to be guided by the experience of early users.

Here are some possible solutions:

1.  Have the hyperlinker understand \newcommand.
2.  Link only to commands that are in a dictionary.
3.  Have the document state up front, that such-and-such are the 
commands it provides.  (This is like 1, except easier for me).
4.  Do nothing.

I'm inclined to have simple constructs like \newcommand understood, but 
implementing this is not yet a priority.  However, (2) might also be 
sensible, if the dictionary is large enough.

I've written only about 200 lines of fairly simple code, so the it's not 
yet time for refactoring.

I think my next priority is to write  a 'dtx2html' translator, so that I 
  can produce some pages to link to.

My other priority is to write regular expressions that will hilight and 
hyperlink style files (rather than tex documents).
