2337=head2 EXTENSION DATABASE SUPPORT
2338
2339Crossfire maintains a very simple database for extension use. It can
2340currently store binary data only (use Compress::LZF::sfreeze_cr/sthaw to
2341convert to/from binary).
2342
2343The parameter C<$family> should best start with the name of the extension
2344using it, it should be unique.
2345
2346=over 4
2347
2348=item $value = cf::db_get $family => $key
2349
2350Returns a single value from the database.
2351
2352=item cf::db_put $family => $key => $value
2353
2354Stores the given C<$value> in the family.
