I'm am trying to devise a mechanism for writing and using dymically included
executable (bound) eupohoria files.
There is a library in the archives already for creating such a thing, but
I'll be damned if I could figure it out.

My plan is to have two include files. One is the 'server' which is included
in the application and controls any open dynamic lirbraries, and the other
is the 'client' which is included in the dynamic library file itself.

I have most all of the details worked out except how to load the client into
the background, to poll for a calls from the server.
This means the method of loading the client into the background, should be
the same for either platform. Or at least possible on either.
