* use ``FieldRRule`` like any other field
* on forms, use ``widget="rrule"``

Technically, this is a wrapper around serialized fields. The value always will be a subclass of dateutil's ``rruleset``. For technical reasons, this class overrides ``__iter__``, so if you need a proper ``rruleset``, call the value: ``my_browse_record.my_field_of_type_rrule()`` - this gives you a vanilla ``rruleset``.
