955 | currently store anything that can be serialised using Storable, which |
|
|
956 | excludes objects. |
|
|
957 | |
|
|
958 | The parameter C<$family> should best start with the name of the extension |

959 | using it, it should be unique. |

965 | Return a hashref for use by the extension C<$family>, which can be |
|
|
966 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
