2300
2301Crossfire maintains a very simple database for extension use. It can
2302currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2303convert to/from binary).
2304
2305The parameter C<$family> should best start with the name of the extension
2306using it, it should be unique.
