Loop time with animation

Unity Engine
1

Got a simple script here that, when attached to a cube, will animate it’s position in a nice sinusodal fashion.

public class Sine : MonoBehaviour
{
    public AnimationCurve anim;
    private Keyframe[] kf; // show in inspector
    void Start()
    {
         kf[0] = new Keyframe(0, 0f, 0, 0);
         kf[1] = new Keyframe(0.5f, 3f, 0, 0);
         kf[2] = new Keyframe(1, 0f, 0, 0);
         anim = new AnimationCurve(kf);
    }		

    void Update()
    {
        transform.position = new Vector3(3, anim.Evaluate(Time.time), 0);
    }
}

However, I have no idea to get the animation to loop once the last keyframe has played. Any ideas?

anim.postWrapMode = WrapMode.Loop

works like a charm, thanks.
