    # with command-line switches and the `SPEC_OPTS` environment variable.
    #
    # Precedence order (where later entries overwrite earlier entries on
    # conflicts):
    #
    #   * Global (`$XDG_CONFIG_HOME/rspec/options`, or `~/.rspec` if it does
    #     not exist)
    #   * Project-specific (`./.rspec`)
    #   * Local (`./.rspec-local`)
    #   * Command-line options
    #   * `SPEC_OPTS`
    #
    # For example, an option set in the local file will override an option set
    # in your global file.
    #
    # The global, project-specific and local files can all be overridden with a
    # separate custom file using the --options command-line parameter.
