From ca3a7cd64822e874076bd23e9981af077eb47b03 Mon Sep 17 00:00:00 2001 From: Alan Conway 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 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/qpid@528668
