Working on scipy doc building I get thisdeprecation warning when running latest sphinxmaster:

/home/larsoner/python/sphinx/sphinx/util/docutils.py:271: RemovedInSphinx30Warning: function based directive support is now deprecated. Use class based directive instead.

Is anyone working on adding a new directive class that can be used instead of the directive function when callingapp.add_directive?

I suspect it should be possible totry/except using a class instead of a function insetup(app) to maintain backward compatibility, so I'd try that first. Should I give this a shot, or is someone else working on it?
