If you use Microsoft Outlook it is possible to use the "Sync"
feature of Google Calendar to syncronize events with Outlook.
(At present it is only possible to syncronize events from your primary Google calendar
and your default Microsoft Outlook calendar, but we expect in the future to be able to
syncronize secondary calendars.)
