+	in Post.php - this just has the following functions:
+
+	void CalendarMain()
+		- loads the specified month's events, holidays, and birthdays.
+		- requires the calendar_view permission.
+		- depends on the cal_enabled setting, and many of the other cal_
+		  settings.
+		- uses the calendar_start_day theme option. (Monday/Sunday)
+		- uses the main sub template in the Calendar template.
+		- goes to the month and year passed in 'month' and 'year' by
+		  get or post.
+		- accessed through ?action=calendar.
+
+	void CalendarPost()
+		- processes posting/editing/deleting a calendar event.
+		- calls Post() function if event is linked to a post.
+		- calls insertEvent() to insert the event if not linked to post.
+		- requires the calendar_post permission to use.
+		- uses the event_post sub template in the Calendar template.
+		- is accessed with ?action=calendar;sa=post.
+
+	void iCalDownload()
+		- offers up a download of an event in iCal 2.0 format.
