Create a gradient in Gimp and export it as a POV-Ray gradient file.
Then in the "src" directory run

	./gdtconvert <mypovrayfile >avenpal.h

and recompile.  (I think that should still work!).  Let us know when you
have one of your choosing :-)

I'd thought of something like that, but have never had time to implement
it...
