+    <description>This program give some basic statistics about the difference between two images.
+It was created as a measure of various color quantization methods.
+
+The statistics given include individual pixel differences and also
+block statistics averaged over blocks of pixels. The latter is a better measure
+when images have been dithered.
+
+The use of these statistics is limited in that they do not contain a model of human vision.
