NAME
       Ocrad - command line text recognition tool

SYNOPSIS
       ocrad [options] [files]

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. The pbm, pgm and ppm formats are collectively  known
       as pnm. If no files are specified, ocrad reads the image from standard input.  If the -o option is not specified, ocrad sends text to stan-
       dard output.

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