23 * Some modifications to be able to compile the todo sql-backend.
24 * A lot of changes fill follow...
25 *
26 * Revision 1.8 2003/08/30 15:28:26 eilers
27 * Removed some unimportant debug output which causes slow down..
28 *
29 * Revision 1.7 2003/08/01 12:30:16 eilers
30 * Merging changes from BRANCH_1_0 to HEAD
31 *
32 * Revision 1.6 2003/07/07 16:19:47 eilers
33 * Fixing serious bug in hasQuerySettings()
34 *
35 * Revision 1.5 2003/04/13 18:07:10 zecke
36 * More API doc

38 * QString = 0l -> QString::null
39 *
40 * Revision 1.4 2003/03/21 14:32:54 mickeyl

50 * all Birthdays/Anniversaries between two dates. This should be used
51 * to show all birthdays in the datebook..
52 * This change is sourcecode backward compatible but you have to upgrade
53 * the binaries for today-addressbook.
54 *
55 * Revision 1.1.2.2 2003/02/11 12:17:28 eilers
56 * Speed optimization. Removed the sequential search loops.

96 * added OBackendFactory for advanced backend access
97 *
98 * Revision 1.1 2002/09/27 17:11:44 eilers
99 * Added API for accessing the Contact-Database ! It is compiling, but
100 * please do not expect that anything is working !
