+  one calendar is associated with each CalendarView (@see calendarview.h).
+  This is an abstract base class defining the interface to a calendar. It is
+  implemented by subclasses like @see CalendarLocal, which use different
+  methods to store and access the data.
+
+  Ownership of events etc. is handled by the following policy: As soon as an
+  event (or any other subclass of IncidenceBase) object is added to the
+  Calendar by addEvent() it is owned by the Calendar object. The Calendar takes
+  care of deleting it. All Events returned by the query functions are returned
+  as pointers, that means all changes to the returned events are immediately
+  visible in the Calendar. You shouldn't delete any Event object you get from
+  Calendar.

+implements the core parser
+
+vobject.c implements an API that insulates the caller from
+the parser and changes in the vCard/vCalendar BNF
+
+port.h defines compilation environment dependent stuff
+
+vcc.h and vobject.h are header files for their .c counterparts
+
+vcaltmp.h and vcaltmp.c implement vCalendar "macro" functions
+which you may find useful.
+
+test.c is a standalone test driver that exercises some of
+the features of the APIs provided. Invoke test.exe on a
+VCARD/VCALENDAR input text file and you will see the pretty
+print output of the internal representation (this pretty print
+output should give you a good idea of how the internal 
+representation looks like -- there is one such output in the 
+following too). Also, a file with the .out suffix is generated 
+to show that the internal representation can be written back 
+in the original text format.
+
+For more information on this API see the readme.txt file
+which accompanied this distribution.
