From 1a7eae919a83618c9f5036416611fc9c8cf3025d Mon Sep 17 00:00:00 2001
From: Guido van Rossum <guido@python.org>
Date: Sat, 21 Feb 1998 20:08:39 +0000
Subject: Adapt to new webchecker structure.  Due to better structure of
 getpage(), much less duplicate code is needed -- we only need to override
 readhtml().
