Subject: [PATCH] A command-line script to load a calendar from an iCalendar
 file.

Currently only tested for calendars, but I suspect it will also
work just fine for an addressbook also.

+Usage:

+
+Where:
+ 'davical.example.com' is the hostname of your DAViCal server.
+ 'replace' is either 'replace' or 'append'
+ '/username/calendar/' is the (sub-)path of the calendar to be updated.
+ 'calendarfile.ics' is the iCalendar file to be loaded.
+
+This script can be used to load events or whole calendars from an external
+iCalendar file.
+
+If the mode is 'replace' and the target calendar does not exist then it will
+be created.  For appending the calendar must always exist.
