        A dictionary of environment variables to be utilized in creating the

            - env:
                OPTIONS: 'ask-passphrase'

            The above illustrates a common ``PyYAML`` pitfall, that **yes**,
            **no**, **on**, **off**, **true**, and **false** are all loaded as
            boolean ``True`` and ``False`` values, and must be enclosed in

            ``PyYAML`` idiosyncrasies can be found :ref:`here
            <yaml-idiosyncrasies>`.

            Use of ``OPTIONS`` on some platforms, for example:
            ``ask-passphrase``, will require ``gpg-agent`` or similar to cache
            passphrases.

            This parameter is not used for making ``yum`` repositories.

    use_passphrase : False
        .. versionadded:: 2016.3.0

        Use a passphrase with the signing key presented in ``keyid``.
        Passphrase is received from Pillar data which could be passed on the
        command line with ``pillar`` parameter. For example:

        .. code-block:: bash

            pillar='{ "gpg_passphrase" : "my_passphrase" }'

            directories which are to be utilized.
