"""Old method of wxPython support for Twisted.

twisted.internet.wxreactor is probably a better choice.

To use::

    | # given a wxApp instance called myWxAppInstance:
    | from twisted.internet import wxsupport
    | wxsupport.install(myWxAppInstance)

Use Twisted's APIs for running and stopping the event loop, don't use
wxPython's methods.

On Windows the Twisted event loop might block when dialogs are open
or menus are selected.
