As much as I hate to change program names, I confess that I can think 
of no better alternative.  The "rview" link to vim was added in recent 
times, I guess.  I'm not even sure what it does differently.  I knew 
that the "view" command was a read-only version of "vi", so it must be 
related.

If we're going to change program names to avoid conflicts, we may as 
well do it right.  I wrote the attached script to detect identically 
named programs in a user's search path.  Just put it on your system and 
execute it:

% chmod +x radcollisions.csh
% ./radcollisions.csh

The script works by first removing components from the search path that 
lead to the program "macbethcal," which I'm assuming is 
Radiance-specific.  Here is the output from my OS X system:

% radcollisions.csh
path was ( /usr/local/ray /Users/gward/bin /usr/local/bin /bin /sbin 
/usr/bin /usr/sbin /Developer/Tools /usr/X11R6/bin . )
path changed to ( /usr/local/bin /bin /sbin /usr/bin /usr/sbin 
/Developer/Tools /usr/X11R6/bin )

/usr/bin/gencat
/usr/bin/lam
/usr/bin/rview

If people can run it on their systems and send the output directly to 
my account <gward@lmi.net>, this should give me a pretty good survey of 
what's out there.  If you want to help me even more, you can run "man 
-k" on the programs it names and send this to me as well.  This will 
give me an idea of where the conflicting programs originated.

Thanks!
