        Historically, setuptools would solicit and store 'extra'
        requirements, including those with environment markers,
        in separate sections. More modern tools expect each
        dependency to be defined separately, with any relevant
        extras and environment markers attached directly to that
        requirement. This method converts the former to the
        latter. See _test_deps_from_requires_text for an example.

        Keyword arguments presented by the caller to
        ``distributions()`` or ``Distribution.discover()``
        to narrow the scope of a search for distributions
        in all DistributionFinders.

        Each DistributionFinder may expect any parameters
        and should attempt to honor the canonical
        parameters defined below when appropriate.

            The sequence of directory path that a distribution finder
            should search.

            Typically refers to Python installed package paths such as
            "site-packages" directories and defaults to ``sys.path``.
