    (description
     "GNU Ocrad is an OCR (Optical Character Recognition) program based on a
feature extraction method.  It reads images in pbm (bitmap), pgm
 (greyscale) or ppm (color) formats and produces text in byte (8-bit)
or UTF-8 formats.

Also includes a layout analyser able to separate the columns or blocks of text
normally found on printed pages.

Ocrad can be used as a stand-alone console application, or as a backend to
other programs.")
