[Pharo-users] parse iCalendar (rfc2445) recurrence rules into a Schedule?

Hi - Is there a package that will convert an iCalendar (*.ics file, rfe2445) VEVENT and its recurrence/exclusion rules/dates into a Schedule in pharo or squeak or gemstone? I've seen the iCal package on Squeaksource but it doesn't seem to interpret the RRULEs into anything other than their constituent parts. Thanks Paul
