Open a listener on TCP port 9020.
Implement the server such that (all client commands are case sensitive):

Client open receives a response of "Welcome to 's chat room"
Client request "help" receives a response of a list of the commands and their syntax.
Client request "test: words" receives a response of "words"
Client request "name: " receives a response of "OK"
Client request "get" receives a response of the entire contents of the chat buffer.
Client request "push: " receives a response of "OK" The result is that ": " is added as a new line to the chat buffer.
Client request "getrange " receives a response of lines through from the chat buffer. getrange assumes a 0-based buffer. Your client should return lines
Client request "SOME UNRECOGNIZED COMMAND" receives a response "Error: unrecognized command: SOME UNRECOGNIZED COMMAND"
Client request "adios" will quit the current connection. Checks for EOF or CLOSE SOCKET.

Socket timeout can be avoided by using the following python code:

s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

Similar functionality should be available from the operating system in other programming languages as well.

All requests and responses must be terminated by a
The appearance of a a signifies the end of a request or a response.
Client commands can be issued in any order.
If a name hasn't been set use "unknown"
If you extend the protocol as part of your extra features, you must support the original protocol in a backwards compatible manner.
Don't insert extra tabbing/formatting unless it is enabled via a protocol extension.

help  
test  
name  
get  
getrange  
adios

All the commands and responses are written out to the screen for checking later.
