  I wondered about how you handled things like:

	\newcommand{\ip}[2]{(#1, #2)}

in the current code.  Both control sequences are linked to an
independent page, which I think is not right: \newcommand should of
course have a page of its own (I understand it still needs to be
written; that's why the link is broken); but \ip certainly shouldn't,
since it's only defined in the document.

  Maybe trying to do both syntax highlighting and command reference in
the same code is too much; do you have any plan on how to deal with
that?
