+ * Revision 1.8  1998-03-05 08:45:11  adam
+ * New result set model and modular ranking system. Moved towards
+ * descent server API. System information stored as "SGML" records.
+ *
+ * Revision 1.7  1997/10/29 12:05:01  adam
+ * Server produces diagnostic "Unsupported Attribute Set" when appropriate.
+ *
+ * Revision 1.6  1997/09/17 12:19:11  adam
+ * Zebra version corresponds to YAZ version 1.4.
+ * Changed Zebra server so that it doesn't depend on global common_resource.
+ *
+ * Revision 1.5  1997/09/05 15:30:08  adam
+ * Changed prototype for chr_map_input - added const.
+ * Added support for C++, headers uses extern "C" for public definitions.
+ *
+ * Revision 1.4  1996/10/29 14:06:48  adam
+ * Include zebrautl.h instead of alexutil.h.
+ *
+ * Revision 1.3  1996/05/09 07:28:54  quinn
+ * Work towards phrases and multiple registers
+ *
+ * Revision 1.2  1995/11/15  19:13:07  adam
+ * Work on record management.
+ *
+ *
  * This interface is used by other modules (the Z-server in particular)
  * to normalize the attributes given in queries.
