+ *
+ * Revision 1.28 1999/03/02 16:15:42 quinn
+ * Added "tagsysno" and "tagrank" directives to zebra.cfg.

+ * Revision 1.27 1998/10/16 08:14:28 adam
+ * Updated record control system.
+ *
+ * Revision 1.26 1998/05/20 10:12:12 adam
+ * Implemented automatic EXPLAIN database maintenance.
+ * Modified Zebra to work with ASN.1 compiled version of YAZ.
+ *
+ * Revision 1.25 1998/03/11 11:19:04 adam
+ * Changed the way sequence numbers are generated.
+ *
+ * Revision 1.24 1998/03/05 08:38:46 adam
+ * New member recordSize in recRetrieveCtrl.
+ *
+ * Revision 1.23 1998/02/10 12:03:05 adam
+ * Implemented Sort.
+ *
+ * Revision 1.22 1997/10/27 14:33:04 adam

+ * bug with negative integers when doing searches with relational
+ * operators.
+ *
+ * Revision 1.21 1997/09/18 08:59:19 adam
+ * Extra generic handle for the character mapping routines.
+ *
+ * Revision 1.20 1997/09/17 12:19:10 adam

+ * null
+ *
+ * Revision 1.16 1996/10/11 10:56:25 adam
+ * New module recctrl. Used to manage records (extract/retrieval).
+ * All record types are accessed by means of definitions in recctrl.h.
+ *
+ * Revision 1.15 1996/06/06 12:08:16 quinn
* Added showRecord Group entry
