* This example will show how easy to create your own ECHO Server.
*
* What should out ECHO Server do?
* Our ECHO Server should listen to port 8000 on the local ip address
* 127.0.0.1 and waiting for clients conntcting in.
* On connect of a client it should send a welcome message.
* While a client is connected, it should wait that the client is
* sending a "\r\n" and the return the message the cleint sended before.
* If the client entered "quit" it should close the connection to the
* client and say "Bye bye..", the same when reciving "shutdown", but
* then we would completely shutdown the Server.
*
* To test the server, you can run it using the console and run telnet
* in an other console window.
* Then connect to "127.0.0.1 port 8000" with telnet and type anything.
* For example under Windows you can exec "cmd" and then type in:
* C:\> telnet 127.0.0.1 8000
* After that you should see the welcome message.
*
* !! Important: Dont forget your firewall settings while testing !!
