2286
2287Crossfire maintains a very simple database for extension use. It can
2288currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2289convert to/from binary).
2290
2291The parameter C<$family> should best start with the name of the extension
2292using it, it should be unique.
