From 20b68e968aa7b7f43bf0cebf58156f4429deeb40 Mon Sep 17 00:00:00 2001
From: Karl Berry <karl@gnu.org>
Date: Sun, 5 Apr 1998 21:19:01 +0000
Subject: (\dosetq): Use \normalturnoffactive instead of just \turnoffactive,
 so \'s in node names are handled properly. (\tie): Move definition to more
 rational position in the file. (\@, \{, etc.): Use decimal numbers in all
 cases, to avoid use of '. Paranoia only. (\+): Turn off once and for all at
 the beginning, and define as \tabalign in @tex.

+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For simple
+% manuals, you can get away with:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o # or whatever, to process the dvi file.
+% The extra runs of TeX get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
