# This script calls build_image to generate a new ChromeOS image,
# using whatever packages are currently in the build tree.  If
# build_images succeeeds, then it pushes the new ChromeOS image onto a
# chromebook, then pings the chromebook to determine if it
# successfully booted.  It then asks the user if the image is good or not,
# allowing the user to conduct whatever tests the user wishes, and waiting
# for a response.
#
# This script is intended to be used by binary_search_state.py, as
# part of the binary search triage on ChromeOS packages.  It should
# return '0' if the test succeeds (the image is 'good'); '1' if the test
# fails (the image is 'bad'); and '2' if it could not determine
# (i.e. in this case, the image did not build).
