Cool. How on Earth does it do that?

Gwydion has the "Melange" C interface generator: interfaces to OpenGL and various
UNIX libraries have been generated using it, but it will be phased out in favour
of Pidgin when that's finished. It is not compatible with FD.

I volunteered to work on Pidgin, but it proved to be outside my area of
competence so I'm working on Gwydion's version of DUIM instead. :-(
I think Pidgin still needs volunteers and it's very clean code to work with, so
if anyone wants to take a look it's included with the current Gwydion Dylan
release in the tools directory (along with Melange).
As an aside, there's an old project in the tools folder called "lisp2dylan" (or
something) that translates a limited subset of Lisp to Dylan. It's fossilized but
may be of interest to some people.
