Branch: CURRENT, Version: 0.21, Package name: ocrad-0.21, Maintainer: pkgsrc-users

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.

Log message:
all: migrate several HOMEPAGEs to https

pkglint --only "https instead of http" -r -F

With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.

This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.
