From 26a723475dc6926bde883c8c7f983ee44d8deb01 Mon Sep 17 00:00:00 2001
From: Alan Conway <aconway@apache.org>
Date: Fri, 13 Apr 2007 20:58:27 +0000
Subject: Moved src/ source code to src/qpid directory:  - allows rhm package
 to build consistently against checked-out or installed qpid.  - consistent
 correspondence between source paths and C++ namespaces.  - consistent use of
 #include <qpid/foo> in source and by users.  - allows header files to split
 over multiple directories,    e.g. separating generated code, separating
 public API from private files.

git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk@528668 13f79535-47bb-0310-9956-ffa450edef68
