  11 Usage:
  12
  13         $basename davical.example.com replace /username/calendar/ calendarfile.ics
  14
  15 Where:
  16  'davical.example.com' is the hostname of your DAViCal server.
  17  'replace' is either 'replace' or 'append'
  18  '/username/calendar/' is the (sub-)path of the calendar to be updated.
  19  'calendarfile.ics' is the iCalendar file to be loaded.
  20
  21 This script can be used to load events or whole calendars from an external
  22 iCalendar file.
  23
  24 If the mode is 'replace' and the target calendar does not exist then it will
  25 be created.  For appending the calendar must always exist.
