When building nbclassic with Python 3.13, the build fails due to its use of the pipes library.

pipes was obsoleted in Python 3 (yes, 3.0) and finally removed in 3.13.
You can probably use shlex instead.

Thank you for opening this issue @0-wiz-0! This was fixed by #286, so now we are waiting on a release!

It should be fixed once that release is out!

That's great, thank you! Looking forward to the release.

Is there a reason this fix was not included in 3.3.7? Cobbler is currently broken in Fedora 41. https://bugzilla.redhat.com/show_bug.cgi?id=2335620
