From 28574b557b40b8ebc964e0b5f27da42f9b4aa611 Mon Sep 17 00:00:00 2001
From: Guido van Rossum <guido@python.org>
Date: Mon, 21 Oct 1996 15:16:51 +0000
Subject: [PATCH] (Fred Drake:) Re-wrote the OptionMenu class to allow access
 to a real Menu object via om['menu'] -- this is necessary to use a
 post-command with an OptionMenu.  The API has not changed.
