    The rarfile_ Python module is now supported for listing the contents of
    rar archives. This is necessary on minions with older releases of the
    ``rar`` CLI tool, which do not support listing the contents in a
    parsable format.
    .. _rarfile: https://pypi.python.org/pypi/rarfile
    List the files and directories in an tar, zip, or rar archive.
    .. note::
    This function will only provide results for XZ-compressed archives if
    the xz_ CLI command is available, as Python does not at this time
    natively support XZ compression in its tarfile_ module. Keep in mind
    however that most Linux distros ship with xz_ already installed.
    To check if a given minion has xz_, the following Salt command can be
    run:
    .. code-block:: bash
    salt minion_id cmd.which xz
    If ``None`` is returned, then xz_ is not present and must be installed.
    It is widely available and should be packaged as either ``xz`` or
    ``xz-utils``.
    name
    Path/URL of archive
    archive_format
    Specify the format of the archive (``tar``, ``zip``, or ``rar``). If
    this argument is omitted, the archive format will be guessed based on
    the value of the ``name`` parameter.
    options
    **For tar archives only.** This function will, by default, try to use
    the tarfile_ module from the Python standard library to get a list of
    files/directories. If this method fails, then it will fall back to
    using the shell to decompress the archive to stdout and pipe the
    results to ``tar -tf -`` to produce a list of filenames. XZ-compressed
    archives are already supported automatically, but in the event that the
    tar archive uses a different sort of compression not supported natively
    by tarfile_, this option can be used to specify a command that will
    decompress the archive to stdout. For example:
    .. code-block:: bash
    salt minion_id archive.list /path/to/foo.tar.gz options=\'gzip --decompress --stdout\'
