# This is a generic ChromeOS package/image test setup script. It is meant to
# be used for either the object file or package bisection tools. This script
# is intended to be used with host object bisection, to bisect the object
# files in a host package.  Since it deals with a host package, there is no
# building an image or flashing a device -- just building the host package
# itself.
#
# 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 build or be flashed).
