Thank you for your PR. I've made a suggestion for a way to refactor is, and avoid repeating ourselves for each package.

I've left some minor comments, otherwise it seems good to go

Hi sir, is there anything else that needs to be added?

Hey @Halimao,

I forgot to approve the workflow, but I checked the changes again and as I expected, there are some failing tests (that depended on help requested being in the output). Please address them (you can probably check for the USAGE string instead).

There's also a build failing in contribs :) Also pinging @zivkovicmilos to hear whether he agrees with the renaming.

Thanks!

@thehowl Hi sir, I have fixed the failed tests, I think we can go now😀
