# This script is intended to be a test to verify that the orchestrator still
# works for others (assuming that they use a similar workflow.)
#
# NOT INTENDED to be used for general building and development, since it removes
# out/ and does other semi-hardcoded things.
################################################################################

# Typical usage:
#
# orchestrator/test_build.sh
#   This builds the default target
# orchestrator/test_build.sh vendor/nothing
#   Build "vendor/nothing", rather than the default target.
#
# Environment variables that affect this script:
#   OUT_DIR: Output directory.  We assume "out" if not set.
#   MCOMBO_DIR: Directory with (test) mcombo files.
#   MCOMBO_FILE: Mcombo file to use.  Default: aosp_cf_arm64_phone.mcombo
#
# Any arguments passed to the script are passed to multitree_build.
