[Tutor] how to build a multiplayer game?

[Chris Fuller]

I think you're on the right track with the IRC idea, but start with something 
simpler.  You can find tutorials or working programs using the asynchat module 
to make a really basic chat client.  Then you build a higher level protocol on 
top of that.  It should take care of most of the low level networking for you.  
But when you're ready for that, look up nonblocking I/O and the select() 
system call.
