A utility for handling schedules and recurrences

["Aloni, Eran" <Eran_Aloni@xxxxxxxxxxxxx>]

Hi all,
I'm looking for a utility (preferably C++ code) that can parse and
"understand" the iCalendar schedule and recurrent schedule format.
"Understanding" means, matching the schedule with a specific date and time
and computing the next time that matches the schedule.

Thanks.
Eran
