"""ChromeOS bisector to bisect a range of chromeos versions.
$ ./ init --old rev1 --new rev2 --dut DUT
$ ./ config switch ./
$ ./ config eval ./
$ ./ run
When running switcher and evaluator, following environment variables
will be set:
BOARD (e.g. samus),
CROS_FULL_VERSION (e.g. R62-9876.0.0),
CROS_SHORT_VERSION (e.g. 9876.0.0),
CROS_VERSION (e.g. R62-9876.0.0).
DUT (e.g. samus-dut), and
MILESTONE (e.g. 62).
