# This is a generic ChromeOS package/image test setup script. It is meant to
# be used for the package bisection tool, in particular when there is a booting
# issue with the image, so the image MUST be 'flashed' via USB.
#
# This script is intended to be used by binary_search_state.py, as
# part of the binary search triage on ChromeOS objects and packages. It should
# return '0' if the setup succeeds; and '1' if the setup fails (the image
# could not built or be flashed).
