2384
2385Crossfire maintains a very simple database for extension use. It can
2386currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2387convert to/from binary).
2388
2389The parameter C<$family> should best start with the name of the extension
2390using it, it should be unique.
