Provide some Data

It can be hard to get hold of the full variety of data that is involved in calendaring. In particular, if you use DAViCal with a non-free calendaring application, or with one which does not work under Linux, it would be useful to get hold of a copy of your calendar with all of the events renamed and other private data removed.

Some particular elements of the calendar entries that are interesting and useful:
 * RRULE: lines, defining repetition of events.
 * VTIMEZONE components, defining timezones.
 * ATTENDEE: or ORGANIZER: lines showing the options used

Ideally you could send whole calendars, of course.
