From 40ff85e256ca9094fb75cdcbabd3442339f91ecd Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Wed, 2 May 2007 23:58:28 +0000
Subject: Added svn:ignore property to everything. Made engine and patch loader
 separate dynamically loaded modules. No more monolithic ingenuity (module
 loaded at runtime).
