'''A helper script for bisecting common problems when working with ArduPilot
When running bisections, you should
export SITL_PANIC_EXIT=1
Bisect between a commit which builds and one which doesn't,
finding the first commit which broke the build with a
specific failure:
git bisect reset
git bisect good a7647e77d9
git bisect bad 153ad9539866f8d93a99e9998118bb090d2f747f
cp -a Tools/autotest/bisect-helper.py /tmp
git bisect run /tmp/bisect-helper.py --build \
--build-failure-string= \
"reference to 'OpticalFlow' is ambiguous"
Work out who killed bebop:
cp -a Tools/autotest/bisect-helper.py /tmp
git bisect reset
git bisect good a7647e77d9 &&

# Use a failing test to work out which commit broke things:
