Correction needed:
"In section 3.1, the default configuration file is located in /etc/qpid-dispatch/qdrouterd.conf and not /etc/qdrouterd. There is also a second file located at /etc/sasl2/qdrouterd.conf."

Addition needed:
"In section 3.2.1 and 3.2.2, the simple_send.py and simple_recv.py commands are available using the commands:

git clone https://github.com/apache/qpid-proton.git
cd qpid-proton/examples/python"
