    Compile a config from a PowerShell script (``.ps1``)

    Args:

        path (str): Path (local) to the script that will create the ``.mof``
            configuration file. If no source is passed, the file must exist
            locally. Required.

        source (str): Path to the script on ``file_roots`` to cache at the
            location specified by ``path``. The source file will be cached
            locally and then executed. If source is not passed, the config
            script located at ``path`` will be compiled. Optional.

        config_name (str): The name of the Configuration within the script to
            apply. If the script contains multiple configurations within the
            file a ``config_name`` must be specified. If the ``config_name`` is
            not specified, the name of the file will be used as the
            ``config_name`` to run. Optional.

        config_data (str): Configuration data in the form of a hash table that
            will be passed to the ``ConfigurationData`` parameter when the
            ``config_name`` is compiled. This can be the path to a ``.psd1``
            file containing the proper hash table or the PowerShell code to
            create the hash table.

            .. versionadded:: 2017.7.0

        config_data_source (str): The path to the ``.psd1`` file on
            ``file_roots`` to cache at the location specified by
            ``config_data``. If this is specified, ``config_data`` must be a
            local path instead of a hash table.

            .. versionadded:: 2017.7.0

        script_parameters (str): Any additional parameters expected by the
            configuration script. These must be defined in the script itself.

            .. versionadded:: 2017.7.0

        salt_env (str): The salt environment to use when copying the source.
            Default is 'base'

    Returns:
        dict: A dictionary containing the results of the compilation

    CLI Example:

    To compile a config from a script that already exists on the system:

    .. code-block:: bash

        salt '*' dsc.compile_config C:\\DSC\\WebsiteConfig.ps1

    To cache a config script to the system from the master and compile it:

    .. code-block:: bash

        salt '*' dsc.compile_config C:\\DSC\\WebsiteConfig.ps1 salt://dsc/configs/WebsiteConfig.ps1
