1110Register a callback for execution when the client sends an (asynchronous)
1111exticmd packet. Exti commands are processed by the server as soon as they
1112are received, i.e. out of order w.r.t. other commands. The first argument
1113is a client socket. Exti commands can be received anytime, even before
1114log-in.
1115
1116If the callback returns something, it is sent back as if reply was being
1117called.

2318currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2319convert to/from binary).
2320
2321The parameter C<$family> should best start with the name of the extension
2322using it, it should be unique.
