/** RCS log of revisions to the C source code.
 *
 * \begin{verbatim}
 * $Log: config.c,v $
 * Revision 1.9  2005/06/28 19:23:56  swift
 * Fixed some minor formatting errors in logentries.
 *
 * Revision 1.8  2005/06/27 15:15:00  swift
 * Added firmware revision to logentry.
 *
 * Revision 1.7  2005/06/23 20:37:16  swift
 * Fixed bug in range-check of the maximum air-bladder pressure.
 *
 * Revision 1.6  2005/06/23 20:32:56  swift
 * Added Added a two-way command to adjust the maximum air-bladder pressure.
 *
 * Revision 1.5  2005/06/14 19:01:15  swift
 * Added a log-entry when configuration supervisor rejects a configuration.
 *
 * Revision 1.4  2005/04/04 22:35:33  swift
 * Change maximum telemetry-retry interval to 6 hours.
 *
 * Revision 1.3  2005/03/30 20:24:37  swift
 * Changed MissionNazi() to ConfigSupervisor().
 *
 * Revision 1.2  2005/02/22 21:00:26  swift
 * Modifications to implement recovery mode.
 *
 * Revision 1.1  2004/12/29 23:11:26  swift
 * Modified LogEntry() to use strings stored in the CODE segment.  This saves
 * lots of space in the DATA segment and significantly speeds code start-up.
