restructuredtext - List subclasses in Sphinx using autodoc -

is there autodoc-directive list subclasses of given class?

if have next python-code:

class base(object): pass class a(base): pass class b(base): pass

is there way generate output like:

classes implementing base: a, b

using sphinx, autodoc , re-structured text. (like :show-inheritance: backwards). like:

.. autoclass:: base of operations :the-command-i-am-missing:

python-sphinx restructuredtext autodoc
