- * Revision 1.10 1995/03/01 14:32:25 adam
+ * Revision 1.22 1995/05/03 07:37:39 adam
+ * CCL commands stop/continue implemented. New functions gw_res_{int,bool}
+ * are used when possible.
+ *
+ * Revision 1.21 1995/05/01 16:26:56 adam
+ * More work on resource monitor.
+ *
+ * Revision 1.20 1995/05/01 12:43:32 adam
+ * First work on resource monitor program.
+ *
+ * Revision 1.19 1995/04/19 16:01:58 adam
+ * Some hacks to get the FIFO communication work!! Isn't reliable.
+ * Resource gw.account added - default account info.
+ *
+ * Revision 1.18 1995/04/19 13:19:09 adam
+ * New command: account - for authentication.
+ *
+ * Revision 1.17 1995/04/19 10:46:18 adam
+ * Persistency works much better now. New command: status - history-like
+ *
+ * Revision 1.16 1995/04/19 07:31:07 adam
+ * First work on Z39.50 persistence.
+ *
+ * Revision 1.15 1995/04/17 09:34:30 adam
+ * Timeout (idletime) adjustable. Minor changes in kernel.
+ *
+ * Revision 1.14 1995/03/28 11:42:34 adam
+ * First use of string-queue utility.
+ *
+ * Revision 1.13 1995/03/28 08:01:25 adam
+ * FIFO existence is used to test for a running kernel.
+ *
+ * Revision 1.12 1995/03/27 12:51:05 adam
+ * New log level in use: GW_LOG_ERRNO.
+ *
+ * Revision 1.11 1995/03/27 08:24:02 adam
+ * First use of gip interface and gw-db.
+ * First work on eti program.
+ *
+ * Revision 1.10 1995/03/01 14:32:25 adam
* Better diagnostics. Default is, that only one database selected when
* several are known.
