# What this script does:
# ----------------------
# (1) run machine_replay.sh on the remote machine to replay the gestures
#     and to generate new logs,
# (2) remove the old logs in tests/logs/ for every board on the host, and
# (3) scp the new logs from the machine into the proper board on the host.
#
# Note: this script needs to be invoked in the firmware_TouchMTB home directory:
#       .../autotest/files/client/site_tests/firmware_TouchMTB
#       inside chroot on the host.
#
# Usage:
#   (cr) .../firmware_TouchMTB $ tools/host_replay.sh -m $MACHINE_IP -s
# Example:
#   (cr) .../firmware_TouchMTB $ tools/host_replay.sh -m 172.30.210.110 -s


# Confirm that current working directory is firmware_TouchMTB.
