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