      4 #     servo-stat DUT ...
      5 #
      6 # Reports the status of the servo (if any) attached to the DUT.
      7 # The DUT name is the host name without the .cros, or -servo.
      8 # For each named DUT, reports a line something like this:
      9 #     DUT ...ABCDEFG is up BOARD=swanky CHROMEOS_RELEASE_VERSION=5995.0.0
     10 #
     11 # The letters are just arbitrary tags printed before any
     12 # long-running operation that might time out.  It allows you to see
     13 # progress, and if things get hung up, you can see where.
