Don't waste your preciouse time with old dead scripts. (Or do
it right and update the code for current releases if you know
enough about TCL/TK).

You don't need much of a front end for Radiance except if you're
afraid of the command line. Most documentation you will find on
the LNBL homepage will use tipped out commands and a text editor
to create the scene files.

You can try the Radiance_on_a_Disk LEARNIX distribution by
Axel Jacobs:

     http://luminance.londonmet.ac.uk/learnix/

The documentation (including the "radcourse" PDFs I mentioned in
my other post) should match this environment so you don't have
to wrestle with the installation to get examples running.

A usefull front-end for the Radiance bundle of tools is the
programm "rad" which will controll the creation of octrees etc.
for you. It's included in the Radiance distribution. Read the
man-page about how to use it.

And start learning bash.

Rayfront is one of the best front ends I know about. Perhaps
you can convince your department to invest in an educational licence?
Would be good for the development of Rayfront, too.
