# so there's two ways (I know of) to proceed here... The first (and the

# here. The second would be to fiddle with the method's metaclass to add
# attributes to it. Both allow the standard action discovery to work, but
# the config method seems a little less magical, so that's what we're
# using right now.
#
# ...and by "less magical" I mean "without the additional metaclass
# tinkering that would be necessary".
