Synopsis
--------
Run demonstration program from the command line::

    # Send fixed measurements "temperature" => 42.84, "humidity" => 83 for demonstration purposes
    php -f clients/runtime/php/terkin-demo.php run demo

    # Send a periodic, slowly oscillating sawtooth signal
    php -f clients/runtime/php/terkin-demo.php run sawtooth

*/

    use Terkin\TelemetryNode;

    // When running from the command line, use some example programs
    // for submitting telemetry data for demonstration purposes.
