+for producing high-quality computer graphics.  @code{POV-Ray} creates
+three-dimensional, photo-realistic images using a rendering technique called
+ray-tracing.  It reads in a text file containing information describing the
+objects and lighting in a scene and generates an image of that scene from the
+view point of a camera also described in the text file.  Ray-tracing is not a
+fast process by any means, but it produces very high quality images with
+realistic reflections, shading, perspective and other effects.")
