   # This tool helps in updating a system.  It restores backed-up
   # configuration files (.rpmsave or other backup notations).
   
   # By default, the .rpmsave suffix is used.
   # Alternatively, there can be two other invocations
   # Invocation #1:
   #   ARGV[0]=suffix
   #   ARGV[1]=.bak
   # Invocation #2:
   #   ARGV[0]=lasttimestamp
   
   # The criteria for the lasttimestamp is that the 
   # file suffix is a '.' followed by a 14-digit
   # time-stamp (YYYYMMDDhhmmss).
   # The time-stamp with the greatest value is
   # taken as the backup file.
