Sr-201-relay.py's primary job in life is to document how to configure and control the SR-201 Ethernet relay, including a working example. The documentation is in the source code.
Because it is a working example it can also be used to configure and control a relay.
There is a README.txt, a very short change log, most importantly the source.
