Greypool - a repology.org maintainer status tool

Greypool uses the repology.org JSON API to check for outdated
packages in repositories checked by repology.org. It works with any
repository, though it's mainly been tested with the "slackbuilds"
(SlackBuilds.org) repo.

It's written in Perl, and designed to use as few external Perl modules
as possible. Currently it requires:

- Either JSON::PP or (preferred) JSON::XS
- POSIX
- Getopt::Long

Also, wget is required.

On first run, you'll be prompted for an email address and a repository.
This is saved in the config file.

Output is a report either as plain text (with or without ANSI color),
comma-separated values (CSV), or HTML.

Greypool complies with repology.org's API guidelines. To avoid excessive
requests, the API responses are cached for 24 hours.

To install, "make install" should suffice. You can override the
install paths on the make command line; see the Makefile for details.
Note that it's a self-contained perl script: for testing, you can
just run it from the source directory.

Greypool was written by B. Watson <urchlay@slackware.uk>, and is
released under the WTFPL.
