var net = require('net');

var bncServer = net.createServer(onConnect);

bncServer.listen(6969, process.argv[2] || 'localhost');

function onConnect(userStream) {
  var serverStream = net.createConnection(6697, 'chat.us.freenode.net');
  userStream.pipe(serverStream);
  serverStream.pipe(userStream);
}
