  # This config does a few things:
  # - Checks C++ and Python code styles (check-style.sh and flake8).
  # - Makes sure sphinx can build the docs without any errors or warnings.
  # - Tests setup.py sdist and install (all header files should be present).
  # - Makes sure that everything still works without optional deps (numpy/scipy/eigen) and
  #   also tests the automatic discovery functions in CMake (Python version, C++ standard).
