 * $Log:	bringdown.c,v $
 * Revision 4.1  88/07/05  15:58:13  mcooper
 * Added copyright notice.
 * 
 * Revision 4.0  88/04/20  15:40:55  mcooper
 * Version 4.
 * 
 * Revision 3.3  88/04/19  18:39:39  mcooper
 * - Do more logging (ala syslog).
 * - Bring the system down with a simple
 *   call to kill(1, SIGTERM) instead of
 *   using -1.  This fixes the problems
 *   with shutting down if someone is in
 *   Suntools.
 * - If we are a 4.3BSD host, then pass
 *   the magically -l option to halt and
 *   reboot as 4.3BSD shutdown does.
 * 
 * Revision 3.2  88/04/11  19:47:36  mcooper
 * Converted all dt_flags to use flag
 * bits.
 * 
 * Revision 3.1  88/02/11  18:59:32  mcooper
 * Fixed bug that caused cancel messages
 * to be send when shutdown time arrived.
 * 
 * Revision 3.0  87/07/24  14:11:54  mcooper
 * Version 3.
