    The legacy format stores paths relative to the info directory, while the
    modern format stores paths relative to the package root, e.g. the
    site-packages directory.

    :param entry: Path parts of the installed-files.txt entry.
    :param info: Path parts of the egg-info directory relative to package root.
    :returns: The converted entry.

    For best compatibility with symlinks, this does not use ``abspath()`` or
    ``Path.resolve()``, but tries to work with path parts:

    1. While ``entry`` starts with ``..``, remove the equal amounts of parts
       from ``info``; if ``info`` is empty, start appending ``..`` instead.
    2. Join the two directly.

aö  Parse a ``requires.txt`` in an egg-info directory.

        This is an INI-ish format where an egg-info stores dependencies. A
        section name describes extra other environment markers, while each entry
        is an arbitrary string (not a key-value pair) representing a dependency
        as a requirement string (no markers).

        There is a construct in ``importlib.metadata`` called ``Sectioned`` that
        does mostly the same, but the format is currently considered private.

        To ease parsing, this converts a legacy dependency entry into a PEP 508
        requirement string. Like ``_iter_requires_txt_entries()``, there is code
        in ``importlib.metadata`` that does mostly the same, but not do exactly
        what we need.

        Namely, ``importlib.metadata`` does not normalize the extra name before
        putting it into the requirement string, which causes marker comparison
        to fail because the dist-info format do normalize. This is consistent in
        all currently available PEP 517 backends, although not standardized.
