From 8c0153e035caa90758a6773493d5859716521e30 Mon Sep 17 00:00:00 2001
From: Gordon Sim <gsim@apache.org>
Date: Wed, 5 May 2010 11:17:41 +0000
Subject: Some cleanup on examples:

* removed obsolete examples (queue-/topic-sender/receiver)
* removed the need to include headers with boost dependencies
* moved the argument handling in darin and spout closer to that of python (and update docs to reflect that)
* changed to ship a manually constructed makefile for messaging examples (generated one doesn't work and maintaining that seems like more work with little benefit)
