For the logs from testing build attempts, see:

You can test you package in mock running:

$ mock -r fedora-rawhide-x86_64 --addrepo=https://download.copr.fedorainfracloud.org/results/ksurma/sphinx-7.2.6/fedora-rawhide-x86_64/ --no-clean your.src.rpm
$ mock -r fedora-rawhide-x86_64 --addrepo=https://download.copr.fedorainfracloud.org/results/ksurma/sphinx-7.2.6/fedora-rawhide-x86_64/ shell

We'd like to include Sphinx 7.2.x in Fedora 40.
