//
// A utilityclass (PHP4 only) to do serverstatus-queries against Halflife/Counterstrike servers
//
// The following functions are available:
//
// Function getServerInfo(serveraddress,serverport)
// Get info about servername,serveraddress,mapname,currentplayers & maxplayers.
//
// Function getServerPlayers(serveraddress,serverport)
// Get info about players currently playing on the server.
// Players are sortet by frags.
//   
// Function getServerRules(serveraddress,serverport)
// Get info about serverrules/settings.
//
// All results are returned in membervariables:
//
