[Radiance-dev] proposal: switching executables from within rad?

[Gregory J. Ward]

It shouldn't break anything.  If the rad input file doesn't have a  
command at the start of an oconv or mkillum or pfilt option, it will  
use the default executable.  What's the problem?  The only issue  
would be using a new format rad input file with an old version of  
rad, but that's going to happen no matter what we do.
