2269
2270Crossfire maintains a very simple database for extension use. It can
2271currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2272convert to/from binary).
2273
2274The parameter C<$family> should best start with the name of the extension
2275using it, it should be unique.
