2339
2340Crossfire maintains a very simple database for extension use. It can
2341currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2342convert to/from binary).
2343
2344The parameter C<$family> should best start with the name of the extension
2345using it, it should be unique.
