    The dictionary structure and keys are always the same, regardless of which
    information items are available in the underlying data sources. The values
    for the various keys are as follows:

    * ``id``:  The result of :func:`distro.id`.

    * ``version``:  The result of :func:`distro.version`.

    * ``version_parts -> major``:  The result of :func:`distro.major_version`.

    * ``version_parts -> minor``:  The result of :func:`distro.minor_version`.

    * ``version_parts -> build_number``:  The result of
      :func:`distro.build_number`.

    * ``like``:  The result of :func:`distro.like`.

    * ``codename``:  The result of :func:`distro.codename`.

    For a description of the *pretty* and *best* parameters, see the
    :func:`distro.version` method.
