 *
 * =====================================================================
 * Version: $Id$
 * =====================================================================
 * History:
 * $Log$
 * Revision 1.10  2003/04/13 18:07:10  zecke
 * More API doc
 * QString -> const QString&
 * QString = 0l -> QString::null
 *
 * Revision 1.9  2003/03/21 10:33:09  eilers
 * Merged speed optimized xml backend for contacts to main.
 * Added QDateTime to querybyexample. For instance, it is now possible to get
 * all Birthdays/Anniversaries between two dates. This should be used
 * to show all birthdays in the datebook..
 * This change is sourcecode backward compatible but you have to upgrade
 * the binaries for today-addressbook.
 *
 * 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.
