)

func Example() {
	fmt.Printf("%d languages\n", len(snowball.Languages()))
	stemmer, err := snowball.New("english")
	if err != nil {
		fmt.Println("error", err)
		return
	}
	defer stemmer.Close()
	fmt.Println(stemmer.Stem("running"))

This project was mostly a learning exercise for me, I don't consider it production quality.
