+    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.
