Again, quick comments...

 - I would *much* rather evolve our existing Sphinx extension in the
   direction we want it to go than to just replace it wholesale.
   Replacement is the wrong approach for a few reasons, including the need
   to minimize change and preserve credit for Jani's work.  Can we work on
   that basis, please?

   Ideally at the time of merging, we would be able to build the docs with
   *either* kerneldoc.

 - I'll have to try it out to see how noisy it is.  I'm not opposed to
   stricter checks; indeed, they could be a good thing.  But we might want
   to have an option so we can cut back on the noise by default.

Thanks,
