Saying Hello

A Myth TV backend typically runs on port 6543 and the first thing you
will need to do when you connect, is tell Myth the protocol version
that you speak. This is done by sending the MYTH_PROTO_VERSION
command. The only argument to this command is the version.
Here's the catch. If you send a version that is different than what
the server is currently running, then it will reject you. When you are
rejected, *** Myth does tell you what version you need to be at in
order for the backend to talk to you***
=========================

So in your app, send the 'MYTH_PROTO_VERSION' command, parse the
response, then have your app branch as appropriate for the version it
tells you it needs, and then resend the proper 'MYTH_PROTO_VERSION'
command. Of course, if you don't support the version being returned,
then you need to exit.
