2316
2317Crossfire maintains a very simple database for extension use. It can
2318currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2319convert to/from binary).
2320
2321The parameter C<$family> should best start with the name of the extension
2322using it, it should be unique.
2323
2324=over 4
2325
2326=item $value = cf::db_get $family => $key

2329

2331
2332Stores the given C<$value> in the family.
