Hello,

A few more links:

• Copr: https://copr.fedorainfracloud.org/coprs/g/osci/rpmdeplint
• PyPI: https://pypi.org/project/rpmdeplint
• Fedora: https://src.fedoraproject.org/rpms/rpmdeplint

I am not familiar with what variables are needed for koji builds to eventually connect to Fedora-CI. Also something I haven't got around is how/if we should make use of pre-installed containers for these plans, maybe controlled via a context variable.

Other than that, I would like to migrate the current rpmdeplint plan to be more compact in a beakerlib script.
