[Radiance-general] pcomb functions

[R Fritz]

I've been working on a Python version of falsecolor, and I've found 
that I really don't understand pcomb. Is the following summary correct?
> The  -e  option  reads a script from its argument and -f reads a script 
> from a file.  -e and -f may be given multiple times and are  processed  
> in  the order they appear on the command line, The scripts are then 
> used to combine the images.
