Just type the command into a shell (console window), and you'll
get a better idea about what you still need to add yourself.

That will be updated when I integrate a more current version
of Radiance with Rayfront.

Btw: Rayfront users don't need to worry about this. They can just
set the sky/ground color with the standard Rayfront color selector,
and the software will normalize the values to a weighted average
of 1 internally. The original deviation is remembered though,
so that you won't get confused too much when you reopen the same
dialog later.
