ast_gen generates a POV-Ray "include" file for the purpose of making
an asteroid field in an image. It is very special-purpose and I didn't
really expect it to be useful for anything other than one particular
image I made. However, feel free to use it if you find it useful.

IMPORTANT: the .exe file here requires that you have GO32.EXE in your path
somewhere. You'll need to get this separately; it is included both in
gforg12a.zip and hutilbin.zip which you can get from:
