    cwd
        The path to the git checkout

    user
        User under which to run the git command. By default, the command is run
        by the user under which the minion is running.

        Windows only. Required when specifying ``user``. This parameter will be

        returns a nonzero exit status.

    output_encoding
        Use this option to specify which encoding to use to decode the output

        cases.

            This should only be needed if the files in the repository were
            created with filenames using an encoding other than UTF-8 to handle
            Unicode characters.
