This is most likely unintentional. Pease consider if this is what you want. 

See `CONTRIBUTING.md` for an explaination.

If you know what you are doing you can disable this check using:

    IKNOWWHATIMDOING=true git commit ...
EOF
    exit 1
    fi
    echo "WARNING: src/deps/facilio is staged for commit. See CONTRIBUTING.md"
fi
