	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		log.Println(r.Method, r.URL.Path)
		h.ServeHTTP(w, r)
	})
}

func main() {
	var addr string
	var path string

	flag.StringVar(&addr, "addr", ":8080", "Listen address")

	flag.Parse()

	log.Printf("Serving pages from %s at %s", path, addr)
	http.Handle("/", loggingHandler(http.FileServer(http.Dir("."))))
	err := http.ListenAndServe(addr, nil)
	log.Printf("Error while serving: %v", err)
