%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
%D This style was made for the \NTS\ presentation at
%D \EUROTEX\ 1999. It's a wink to programming in a webbed way.
%D This is just one way of implementing such a style. Today
%D we have more \METAPOST\ interfacing available, and
%D thereby moore tools and alternative ways to reach such a
%D goal. I must admit that the main macro looks fuzzy. On
%D the other hand, the presentation can look quite structured.
