"""
This module provides wxPython event loop support for Twisted.

In order to use this support, simply do the following::

|  from twisted.internet import wxreactor
    |  wxreactor.install()

Then, when your root wxApp has been created::

| from twisted.internet import reactor
    | reactor.registerWxApp(yourApp)
    | reactor.run()

Then use twisted.internet APIs as usual. Stop the event loop using
reactor.stop(), not yourApp.ExitMainLoop().

IMPORTANT: tests will fail when run under this reactor. This is
expected and probably does not reflect on the reactor's ability to run
real applications.
