From 188e34375827915a9832ddb1db4b94494bbee455 Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Wed, 1 Aug 2007 14:10:46 +0000
Subject: Clean up engine/client interfaces. Hide Response, now an internal
 engine implementation detail (and not a problem for script bindings anymore).
