From cda1bd6cfe8cad9943f0c1991b690313b5be9bef Mon Sep 17 00:00:00 2001
From: Neil Conway <neilc@samurai.com>
Date: Tue, 24 Aug 2004 00:06:51 +0000
Subject: [PATCH] Various minor improvements to the SGML documentation: fix
some incorrect SGML markup, add a "deprecated features" section to the 8.0
release notes, untabify release.sgml and runtime.sgml, and make some other
minor improvements.
