From bd3090d4d659951ed38d1da0f44c3e59ec830bea Mon Sep 17 00:00:00 2001
From: Fred Drake
Date: Fri, 18 May 2001 15:32:59 +0000
Subject: [PATCH] Added test suite for the new HTMLParser module, originally
from the TAL/PageTemplate package for Zope. This only needed a little
boilerplate change; the tests themselves are unchanged.
