The simple way to do it, IMO, is to import a joint module, called
something like cfg. I just did a little hack in a script with
cfg = imp.new_module('cfg')
but I don't know how well that works across modules. I think you'd need
to poke it into sys.modules in order for it to be shared, but I haven't
tested it.
