From d22ac4bbbd52fc8cbf80f864c49c904b0b24a529 Mon Sep 17 00:00:00 2001
From: "Rafael H. Schloming" <rhs@apache.org>
Date: Tue, 11 Aug 2009 15:40:19 +0000
Subject:  - removed old and redundent tests

 - removed old test harness in favor of qpid-python-test

 - modified qpid-python-test to support "skipped" tests, these are
   tests that failed due to an anticipated environmental reason such
   as the broker is not running or it is the wrong version

 - modified the qpid-python-test harness to exit with appropriate
   error codes based on the test results

 - modified the python clients to report version mismatches rather
   than framing errors

 - made qpid_config provide variables for 0-8, 0-9, and 0-10 versions
   of the spec

 - modified the 0-10 client to directly codegen classes

 - added new 0-10 framing layer based on push parsing rather than pull
   parsing

 - added numerous framing tests
