// This is the network info/connection protocol.  It is used to find Quake

// Quake game protocol (documented elsewhere) is used.

// General notes:
//	game_name is currently always "QUAKE", but is there so this same protocol
//		can be used for future games as well; can you say Quake2?

//	note:
//		There are two address forms used above.  The short form is just
//		a port number.  The address that goes along with the port is
//		defined as "whatever address you receive this reponse from".
//		This lets us use the host OS to solve the problem of multiple
//		host addresses (possibly with no routing between them); the
//		host will use the right address when we reply to the inbound
//		connection request.  The long from is a full address and port
//		in a string.  It is used for returning the address of a server
//		that is not running locally.
