Your instructions don't seem to say how to get a rainbow to appear. They 
just seem to describe the options for tailoring it once you get to see it. 
Do you have a simple scene file to serve as an example for getting the 
default one to appear?

The include file seems to add a couple of spheres to the scene, but I placed 
a camera and a light source at the default location specified in the include 
file and got a black screen. I changed the background to white and got a 
white screen, so I guess it needs something specific in the scene file to 
make the rainbow visible.

BTW. You shouldn't necessarily be discouraged by a lack of feedback. The 
POV-Ray object collection has had over 20,000 downloads since it started a 
year ago, but there's been very little feedback.
