3# Usage:
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.
