Great, I'll add this.

Ok, so should I just remove the CC licence?

I agree, - the docs won't build if sphinx /doxygen isn't found - but
when I built on my laptop in buildroot, it 'discovered' the exectuable
for sphinx, but without an install inside the buildroot environment so
it failed at first.

So a --disable-docs option is certainly going to be useful. I'll try and
get it added and included for this packaging process.

Ack ...

Are all of these relevant actually? I wonder if I should drop the
cc-by-sa-v4.0 if I'm dropping the docs licence above, and the DCO, as
that's only really about contributing to the project?
