Tagging @divyansh42 to check if he's still active in this repo. And @der-eismann

[der-eismann]

Hey @Eusebiotrigo! Not much I can do, this and buildah-build seem to be dead at this point. My PR over there got merged, but not released yet. We maintain our own forks, but we don't have the capability to run them as proper open source projects.

[Eusebiotrigo]

Thanks @der-eismann. It would be time to create our own forks or look for alternatives.

[divyansh42]

Apologies for the delay. We were not able to look at these due to other multiple priorities.

[divyansh42]

@Eusebiotrigo could you please rebase your PR? I did some changes.

[divyansh42]

Okay, I merged that as it is.
