I always thought (with no basis in actual knowledge of course) that it was executable, because CERN used to post Postscript maps to their locations in their newsgroups, and I used to use Ghostscript to display them. And as I was using an old, slow machine, I could watch the maps being drawn in a leisurely way. Not at all like HTML. -- Peter

By executable, I mean that it has program states, loops, branching, conditionals and so on. A slow enough machine will render HTML slowly too. Daniele
