2179currently store anything that can be serialised using Storable, which
2180excludes objects.
2181
2182The parameter C<$family> should best start with the name of the extension

2188
2189Return a hashref for use by the extension C<$family>, which can be

2191C<cf::db_sync>.
2192

2199Stores the given family hashref into the database. Updates are delayed, if
2200you want the data to be synced to disk immediately, use C<cf::db_sync>.
2201
