48 * Revision 1.15 1995/07/03 12:59:28 adam
49 * New option for eti: -c dir to chdir before start.
50 * Setting change: gw.max.show defaults to 100.
52 * Revision 1.14 1995/05/19 13:25:59 adam
53 * Bug fixes. Better command line options.
55 * Revision 1.13 1995/05/16 09:40:41 adam

58 * Revision 1.12 1995/05/03 07:37:35 adam
59 * CCL commands stop/continue implemented. New functions gw_res_{int,bool}
60 * are used when possible.
62 * Revision 1.11 1995/05/01 16:26:56 adam
63 * More work on resource monitor.

76 * Resource gw.account added - default account info.
78 * Revision 1.6 1995/04/17 09:34:27 adam
79 * Timeout (idletime) adjustable. Minor changes in kernel.
81 * Revision 1.5 1995/03/31 09:43:13 adam
82 * Removed unused variable.
84 * Revision 1.4 1995/03/28 11:42:34 adam
85 * First use of string-queue utility.
87 * Revision 1.3 1995/03/28 08:01:23 adam
88 * FIFO existence is used to test for a running kernel.
90 * Revision 1.2 1995/03/27 12:51:05 adam
91 * New log level in use: GW_LOG_ERRNO.
