How do I configure a Broadcast Client?

Using the line broadcastclient will enable listening to broadcasts. As anybody can send out any broadcasts, use of authentication is strongly advised. In version 3 you would have to define the broadcastdelay to compensate the network delay. In version 4 the client actively will query a broadcasting server to calibrate the delay. More details can be found in file html/assoc.htm (Association Management).
