 If ``solc`` is called with the option ``--standard-json``, it will expect a JSON input (as explained below) on the standard input, and return a JSON output on the standard output. This is the recommended interface for more complex and especially automated uses. The process will always terminate in a "success" state and report any errors via the JSON output.
 The option ``--base-path`` is also processed in standard-json mode.
