From fb36aa320b82e78b70557bccf72da08734ef2184 Mon Sep 17 00:00:00 2001
From: Diego Pettenò <flameeyes@gentoo.org>
Date: Mon, 22 Sep 2008 13:43:02 +0000
Subject: Extend build-docbook-catalog to support different types of xsl
 stylesheets (which include xsl-ns for Docbook 5).
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Be ready to support xsl-xalan and xsl-saxon even if they are not
available in Portage too.

Also, assume that the directories are unversioned, as the new ebuilds
don't version them anymore.

The script could be deprecated, for what concerns XSL stylesheets, by
using an eclass instead.
