This runs rclone so that it only listents to remote control commands.

This is useful if you are controlling rclone via the rc API.

If you pass in a path to a directory, rclone will serve that directory
for GET requests on the URL passed in.  It will also open the URL in
the browser when rclone is run.

See the [rc documentation](/rc/) for more info on the rc flags.
