This code only runs at all if sphinx is installed, since it's
sphinx-build that runs it. The conditional is whether the OVS sphinx
theme is installed.
My question is, what version of Sphinx (not OVS, not the OVS sphinx
theme) introduced a theme named "classic"? If it is newer than the
oldest version of Sphinx that OVS requires, then this patch will break
things and we will need to make a choice:
1. Refine the patch to use "default" if "classic" is not
available.
2. Live with the warning.
3. Increase OVS's minimum required Sphinx version.
Thanks,
Ben.
