[Radiance-general] Radzilla again

[Carsten Bauer]

Hi,

so my reply comes a bt late, as the questions are already answered 
-thanx very much!

The basic idea is that current radzilla is not 'standalone' and thus 
relies on a working classic Radiance installation. Classic Radiance 
offers a lot of helper files for all sorts of calculations in 
conjunction with the functional language, and when the program needs one 
ot these, especially the initialization file 'rayinit.cal', it searches 
the directories listed in the mentioned 'RAYPATH' shell enviromment 
variable. And in this respect radzilla  behaves just like classic Radiance.
The whole environment variable business may indeed seem a bit strange at 
the first glance to those less aquainted with the UNIX/Linux world,
especially because you set these variables 'globally' in your shell  
init file, which itself has nothing to to with Radiance or radzilla..
The alternative (not implemented) approach would be to put this sort of 
information in some kind of .radiancerc or .radzillarc file in a users 
home directory.
