1256exticmd packet. Exti commands are processed by the server as soon as they
1257are received, i.e. out of order w.r.t. other commands. The first argument
1258is a client socket. Exti commands can be received anytime, even before

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.
