  *
  * =====================================================================
  * Version: $Id$
  * =====================================================================
  * History:
  * $Log$
+ * Revision 1.8  2003/02/21 16:52:49  zecke
+ * -Remove old Todo classes they're deprecated and today I already using the
+ * new API
+ * -Guard against self assignment in OTodo
+ * -Add test apps for OPIM
+ * -Opiefied Event classes
+ * -Added TimeZone handling and pinning of TimeZones to OEvent
+ * -Adjust ORecur and the widget to better timezone behaviour
+ *
  * Revision 1.7  2003/02/16 22:25:46  zecke
  * 0000276 Fix for that bug.. or better temp workaround
  * A Preferred Number is HOME|VOICE
  * A CellPhone is HOME|VOICE|CELL the type & HOME|VOICE test
  * triggers both
  * and the cell phone number overrides the other entries..
  *
  * as a temp I check that it's not equal to HOME|VOICE|CELL before setting the
  * number
  *
  * The right and final fix would be to reorder the if statement to make it
  * if else based and the less common thing put to the bottom
  *
  * OTodoAccessVcal fix the date for beaming
  *
  * Revision 1.6  2003/01/13 15:49:31  eilers
  * Fixing crash when businesscard.vcf is missing..
  *
  * Revision 1.5  2002/12/07 13:26:22  eilers
  * Fixing bug in storing anniversary..
  *
  * Revision 1.4  2002/11/13 14:14:51  eilers
  * Added sorted for Contacts..
  *
  * Revision 1.3  2002/11/11 16:41:09  kergoth
  * no default arguments in implementation
  *
  * Revision 1.2  2002/11/10 15:41:53  eilers
  * Bugfixes..
  *
  * Revision 1.1  2002/11/09 14:34:52  eilers
  * Added VCard Backend.
