"""
Setup pubsub for the *arg1* message protocol. In a default pubsub installation
the default protocol is *kargs*.
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).
::
from .. import setuparg1
from .. import pub
The *arg1* protocol is identical to the legacy messaging protocol from
first version of pubsub (when it was still part of wxPython) and
is *deprecated*. This module is therefore *deprecated*.
