+ * Revision 1.82 1998-05-20 10:12:15 adam
+ * Implemented automatic EXPLAIN database maintenance.
+ * Modified Zebra to work with ASN.1 compiled version of YAZ.
+ *
+ * Revision 1.81 1998/03/11 11:19:04 adam
+ * Changed the way sequence numbers are generated.
+ *
+ * Revision 1.80 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 1.79 1998/02/17 10:32:52 adam
+ * Fixed bug: binary files weren't opened with flag b on NT.
+ *
+ * Revision 1.78 1998/02/10 12:03:05 adam
+ * Implemented Sort.
+ *
+ * Revision 1.77 1998/01/12 15:04:08 adam
* The test option (-s) only uses read-lock (and not write lock).
