======
* ``pmxbot.core.AliasHandler`` now expects a 'parent' argument referring to
the parent command. The ``doc`` parameter is no longer honored, but instead
refers to ``parent.doc``. Commands that construct AliasHandlers explicitly
will need to be updated, though no known implementations do so.
* ``commands`` will now defer to the decorated function's docstring for the
command help if no doc is supplied. So now the following are equivalent::
command('something', doc='do something special')
def func(...):
return 'something'
command('foo')
def func(...):
"""
do something
special
"""
return 'something'
