%D The question is: should I still document this in interaction.tex or just
%D assume it's obsolete technology \unknown

%D This is only a placeholder that demonstrates the usage of swf resources.
%D There is no need to include this file into the format. The module was
%D tested by Luigi and Willi and based on their suggestions the functionality
%D was improved.

%D Embedding (and using) movies used to be a breeze in acrobat but depended
%D on a plugin. Then we got renditions that depended on the built-in flash
%D player. And now we have rich media, depending on whatever and being able
%D to use the flash player as well ... but it's an erratic and soon obsolete
%D adventure. So \unknown\ we do provide the user the means but stay away
%D from it ourselves: it's a dead end. The following tricks use the already
%D present shockwave (flash) trickery.
%D
%D At some point we will no longer provide this in the core but load it at
%D runtime.
