+ * Revision 1.92 1999-05-26 07:49:13 adam
+ * C++ compilation.
+ *
+ * Revision 1.91 1999/02/02 14:51:13 adam
+ * Updated WIN32 code specific sections. Changed header.
+ *
+ * Revision 1.90 1998/11/16 16:03:43 adam
+ * Moved loggin utilities to Yaz. Was implemented in file zlogs.c.
+ *
+ * Revision 1.89 1998/11/16 10:11:55 adam
+ * Added addtional info for error 114 - unsupported use attribute.
+ *
+ * Revision 1.88 1998/10/18 07:54:52 adam
+ * Additional info added for diagnostics 114 (Unsupported use attribute) and
+ * 121 (Unsupported attribute set).
+ *
+ * Revision 1.87 1998/09/28 11:19:12 adam
+ * Fix for Compiled ASN.1.
+ *
+ * Revision 1.86 1998/09/22 10:48:20 adam
+ * Minor changes in search API.
+ *
+ * Revision 1.85 1998/09/22 10:03:43 adam
+ * Changed result sets to be persistent in the sense that they can
+ * be re-searched if needed.
+ * Fixed memory leak in rsm_or.
+ *
+ * Revision 1.84 1998/09/18 12:41:00 adam
+ * Fixed bug with numerical relations.
+ *
+ * Revision 1.83 1998/09/02 13:53:19 adam
+ * Extra parameter decode added to search routines to implement
+ * persistent queries.
+ *
+ * Revision 1.82 1998/06/26 11:16:40 quinn
+ * Added support (un-optimised) for left and left/right truncation
+ *
+ * Revision 1.81 1998/06/24 12:16:14 adam
+ * Support for relations on text operands. Open range support in
+ * DFA module (i.e. [-j], [g-]).
+ *
+ * Revision 1.80 1998/06/23 15:33:34 adam
+ * Added feature to specify sort criteria in query (type 7 specifies
+ * sort flags).
+ *
+ * Revision 1.79 1998/06/22 11:35:09 adam
+ * Minor changes.
+ *
+ * Revision 1.78 1998/06/08 14:43:17 adam
+ * Added suport for EXPLAIN Proxy servers - added settings databasePath
+ * and explainDatabase to facilitate this. Increased maximum number
+ * of databases and attributes in one register.
+ *
+ * Revision 1.77 1998/05/20 10:12:22 adam
+ * Implemented automatic EXPLAIN database maintenance.
+ * Modified Zebra to work with ASN.1 compiled version of YAZ.
+ *
+ * Revision 1.76 1998/04/02 14:35:29 adam
+ * First version of Zebra that works with compiled ASN.1.
+ *
+ * Revision 1.75 1998/03/05 08:45:13 adam
* New result set model and modular ranking system. Moved towards
* descent server API. System information stored as "SGML" records.
