From 16e203a0d32df9829bcf4fb738ef89fc94404155 Mon Sep 17 00:00:00 2001
From: Andrew Stitcher <astitcher@apache.org>
Date: Mon, 2 Apr 2007 11:40:48 +0000
Subject: Fix for the most disruptive items in QPID-243. * All #include lines
 now use '""' rather than '<>' where appropriate. * #include lines within the
 qpid project use relative includes so that   the same path will work in
 /usr/include when installed as part of the   client libraries. * All the
 source code has now been rearranged to be under src in a directory  
 analogous to the namespace of the classes in it.

git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@524769 13f79535-47bb-0310-9956-ffa450edef68
