longDescription =
'' 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.
