# < mhy> whilst you're here, if you have time to look at and merge
#        https://salsa.debian.org/ftp-team/dak/-/merge_requests/281 , I'd be
#        nice to you for at least 5 minutes
# < Ganneff> ...
# < Ganneff> 10!
# < mhy> Done
# ...
# < mhy> god I hate dak's argument parsing.  One day far in the future
#        when I have lots of time, I'm going to rip it all out
# < Ganneff> and replace it with rust
# * Ganneff hides
# < mhy> I'll replace *you* with rust
# < mhy> oh blast, I didn't even make 10 minutes
