From c5eb1148b99cf88555c0a516e1218bdb74ab0080 Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Tue, 1 May 2007 04:01:04 +0000
Subject: Converted Raul (and thus Ingen and Machina) to use Redland over
 Raptor/Rasqal independently. Fixed patch loading for Ingen (local only, still
 something wrong with remote...).
