The source code is automatically formatted using clang-format.

The output can vary between versions, so make sure to install `clang-format`
version `10.0`, and have `clang-format-10` in your execution path,
so that the helper script `tools/format.sh` can find it.

Check out a new branch, make modifications and push the branch to your fork:
