2285
2286Crossfire maintains a very simple database for extension use. It can
2287currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2288convert to/from binary).
2289
2290The parameter C<$family> should best start with the name of the extension
2291using it, it should be unique.
