# This script will update the host art VM in tools/linux/art

# Before running this script make sure that you have a full android build
# and that the host Art version required is build in ~/android/master:
#
#  m -j24
#  m -j24 build-art
#
# Maybe also run the Art host tests:
#
#  m -j24 test-art-host
