    <p>Writes <code>msg.payload</code> to the file specified, for example to create a log.</p>
    <p>The filename can be configured in the node. If left blank it should be
    set by <code>msg.filename</code> on the incoming message.</p>
    <p>A newline is added to every message. But this can be turned off if required, for example, to allow binary files to be written.</p>
    <p>The default behaviour is to append to the file. This can be changed to overwrite the file each time, for example if you want to output a "static" web page or report.</p>
    <p>This node can also be configured to delete a file if required.</p>
