"""Build and run go/ab/git_master-art-host target

This script is executed by the android build server and must not be moved,
or changed in an otherwise backwards-incompatible manner.

Provided with a target name, the script setup the environment for
building the test target by taking config information from
from target_config.py.

See target_config.py for the configuration syntax.
