++ \brief Show how to write a simple WebSocket client application.
++
++ The Echo Client shows how to use the \l {Qt WebSockets}{WebSocket}
++ API to send a message to a server and process whatever response the
++ server returns - in this case, simply reporting the response.
++
++ The client by default opens a WebSocket connection to a server listening
++ on local port 1234. When the connection attempt is successful, the client
++ will send a message to the server and print out whatever response the
++ server sends. The client then closes the connection.
++

++
++ For the sake of illustration, we use the \l {WebSocket Echo Server}, whose
++ reply is simply the message that was sent.
