+pixels of a moving window (retina) is trained to associate these input stimuli
+to the corresponding response in one or several output image(s).  The resulting
+filter can be loaded in SExtractor to operate complex, wildly non-linear filters
+on astronomical images.  Typical applications of EyE include adaptive filtering,
+feature detection and cosmetic corrections.")
