1251Register a callback for execution when the client sends an (asynchronous)
1252exticmd packet. Exti commands are processed by the server as soon as they
1253are received, i.e. out of order w.r.t. other commands. The first argument
1254is a client socket. Exti commands can be received anytime, even before
1255log-in.

2386Crossfire maintains a very simple database for extension use. It can
2387currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2388convert to/from binary).
2389
2390The parameter C<$family> should best start with the name of the extension
2391using it, it should be unique.
