+  KOEventView is the abstract base class from which all other
+  calendar views for event data are derived.  It provides methods for
+  displaying
+  appointments and events on one or more days.  The actual number of
+  days that a view actually supports is not defined by this abstract class;
+  that is up to the classes that inherit from it.  It also provides
+  methods for updating the display, retrieving the currently selected
+  event (or events), and the like.
