These files are intended to check which things break on an upgrade and if our compat classes are working. The files cover all different cases of recurrence rules that could be produced by KAlarm from KDE 3.4. The reference data are the occurrences that were generated with KOrganizer from KDE 3.4. They do not alway follow the RFC, but we need to ensure that the rrule is adjusted by a Compat class so that the new version produces the same set of occurrences.
