"""
Setup pubsub for the kwargs message protocol. In a default installation
this is the default protocol so this module is only needed if setupkargs
utility functions are used, or in a custom installation where kwargs
is not the default messaging protocol (such as in some versions of
wxPython).
This module must be imported before the first ``from pubsub import pub``
statement in the application. Once :mod:pub has been imported, the messaging
protocol cannot be changed (i.e., importing it after the first
``from pubsub import pub`` statement has undefined behavior).
