   3 # This  script was  written  by  Jim Isaacson  <jcisaac@crl.com>.  It is
   4 # designed to work  as a script to use the  SecureCARD(tm) device.  This
   5 # little device is mated with a central controller. The number displayed
   6 # on this card changes every so often and  you need to enter  the number
   7 # along with your user account name in order to gain access.  Since chat
   8 # is based upon fixed strings this procedure will not work with chat.
   9 #
  10 # It is included by permission. An excellent reference for the expect
  11 # program used by this script is in the book:
