# Simple script to show a manual power prompt for when you want to use
# automated hardware testing with testimage.bbclass but you don't have a
# web-enabled power strip or similar to do the power on/off/cycle.
#
# You can enable it by enabling testimage (see the Yocto Project
# Development manual "Performing Automated Runtime Testing" section)
# and setting the following in your local.conf:
#
# TEST_POWERCONTROL_CMD = "${COREBASE}/scripts/contrib/dialog-power-control"
