Hyper-DVI, then. Sure, should work just fine. I was thinking that
Hyper-Postscript would take about the same amount of work, and probably
provide a bigger payback, in terms of versatility. In fact, Paul
Kranenburg at Erasmus University in the Netherlands just sent me a
version that only needs two changes: first, the links it supports are
Sun answerbook links, rather than Internet URL's (trivial change); and
second, it's implemented as an XView widget rather than an Xt widget
(sort of a big change). The links are just comments in the Postscript
which indicate a document, and a sensitive rectangle on the page. The
widget ``signals'' the specified document when the user clicks on the
specified region. Easy. In fact, dvips could generate this format from
Hyper-DVI, I imagine.
