%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.

%D As part of the interaction manual writing this code was moved here. It's
%D kind of obsolete as shockwave is obsolete. Anywaym, here's how it works.
%D One can actually set all kind of properties but let's not waste time on
%D that. Maybe some day \PDF\ will have proper native video support.
