[Radiance-general] Using dayfact Script

[Greg Ward]

Hi Ganesh,

The key to your problem is written in the last line of the script  
output -- apparently, your version of Unix lacks a "mail" command, so  
you didn't get any notification.  I expect your results are sitting in  
the file you named in the working directory.  Did you check?  The  
ximage command may be used to display it.

Cheers,
-Greg
