From 7267fdd7a3ae0a8a169e9730bdfaa46fde7dd94b Mon Sep 17 00:00:00 2001
From: Peter Eisentraut <peter_e@gmx.net>
Date: Sun, 5 Nov 2000 21:04:07 +0000
Subject: [PATCH] Add some configure checks for DocBook and related tools. 
 With a somewhat standard installation layout it should be possible to build
 the HTML and print documentation without additional manual setup.
