[Radiance-general] no output from optics2rad

[Greg Ward]

Hi Chris,

Why is your description missing the "glass" descriptor Optics usually  
produces?  The optics2rad script is a bit fragile to such  
oversights.  Maybe you just took it out for brevity.

In any case, the optics2rad script doesn't like underscores in names  
any better than it likes Spaces.  The only underscore you can have is  
before the final "_glass", "_front" or "_back".  The issue is not  
with Radiance but with the rcalc program, which looks for the end of  
the name by searching for an underscore.  Not much way around it, I'm  
afraid.  All three names need to be identical as well, e.g.:

void glass SB60-Starphire-8_glass
