+1, higher setuptools version is probably better as it's still working on the
oldest distros (than 68 version I added in my patchset). IMHO it'd be good to
add (before merge) a comment to requirements.txt that it's just a temporary
workaround (once linuxdoc is released I'd upgrade it and remove the dependency).

Kind regards,
Petr
