	// By wrapping the handler with InstrumentHandler, request count,
	// request and response sizes, and request latency are automatically
	// exported to Prometheus, partitioned by HTTP status code and method
	// and by the handler name (here "fileserver").

	// The Prometheus handler still has to be registered to handle the
	// "/metrics" endpoint. The handler returned by prometheus.Handler() is
	// already instrumented - with "prometheus" as the handler name. In this
	// example, we want the handler name to be "metrics", so we instrument
	// the uninstrumented Prometheus handler ourselves.
