From 9a30f30107a16202c16672f0c3e67684130c284a Mon Sep 17 00:00:00 2001
From: Markus Armbruster <armbru@pond.sub.org>
Date: Sun, 19 Feb 2006 07:04:30 +0000
Subject: [PATCH] (builtindir): New econfig key, variable and make variable.
 (subst.in): Substitute it.  Fix prerequisites. (read_builtin_tables): New.
 (main): Call it.  This doesn't do anything, because no builtin tables have
 been defined.
