  - tox: Keeping going with docs
    
    Sphinx 1.8 introduced [1] the '--keep-going' argument which, as its name
    suggests, keeps the build running when it encounters non-fatal errors.
    This is exceptionally useful in avoiding a continuous edit-build loop
    when undertaking large doc reworks where multiple errors may be
    introduced.
