936C<rent::overview>, as used by the C<rent> extension.

957=head2 EXTENSION DATABASE SUPPORT
958
959Crossfire maintains a very simple database for extension use. It can
960currently store anything that can be serialised using Storable, which
961excludes objects.
962
963The parameter C<$family> should best start with the name of the extension
964using it, it should be unique.
965
966=over 4
967
968=item $hashref = cf::db_get $family
969
970Return a hashref for use by the extension C<$family>, which can be
971modified. After modifications, you have to call C<cf::db_dirty> or
972C<cf::db_sync>.
973
974=item $value = cf::db_get $family => $key
975
976Returns a single value from the database
977
978=item cf::db_put $family => $hashref
979
980Stores the given family hashref into the database. Updates are delayed, if
981you want the data to be synced to disk immediately, use C<cf::db_sync>.
982
983=item cf::db_put $family => $key => $value
984
985Stores the given C<$value> in the family hash. Updates are delayed, if you
986want the data to be synced to disk immediately, use C<cf::db_sync>.
987
988=item cf::db_dirty
989
990Marks the database as dirty, to be updated at a later time.
991
992=item cf::db_sync
993
994Immediately write the database to disk I<if it is dirty>.
