Hi Randy,
	You are required to accept the POV-Ray license.  However, once you 
have accepted it, Chimera will remember that and won't keep asking you. 
  So if you start up Chimera normally and save any kind of POV-Ray image 
and accept the license, you will then be able to run your script in 
nogui mode on the same machine without the licensing request halting 
the script.
	If this is still a problem for the way you want to use the script, let 
me know.  We still intend to make it possible to save non-ray traced 
images in nogui mode, but prioritizing that would depend on whether 
POV-Ray images are going to work as a stopgap measure or not.
