developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
GNU Ocrad is an OCR (Optical Character Recognition) program based
on a feature extraction method. It reads a bitmap image in pbm or
pgm formats and produces text in byte (8-bit) or UTF-8 formats.
Ocrad includes a layout analyser able to separate the columns or
blocks of text normally found on printed pages.
