1254Register a callback for execution when the client sends an (asynchronous)
1255exticmd packet. Exti commands are processed by the server as soon as they
1256are received, i.e. out of order w.r.t. other commands. The first argument
1257is a client socket. Exti commands can be received anytime, even before
1258log-in.

2385Crossfire maintains a very simple database for extension use. It can
2386currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2387convert to/from binary).
2388
2389The parameter C<$family> should best start with the name of the extension
2390using it, it should be unique.
