"""
Contains functions used to test the ArduPilot build_options.py structures

To extract feature sizes:

cat >> /tmp/extra-hwdef.dat <<EOF
undef AP_BARO_MS56XX_ENABLED
define AP_BARO_MS56XX_ENABLED 1
EOF

nice time ./Tools/autotest/test_build_options.py --board=CubeOrange --extra-hwdef=/tmp/extra-hwdef.dat --no-run-with-defaults --no-disable-all --no-enable-in-turn | tee /tmp/tbo-out  # noqa
grep 'sabling.*saves' /tmp/tbo-out

 - note that a lot of the time explicitly disabling features will make the binary larger as the ROMFS includes the generated hwdef.h which will have the extra define in it  # noqa
