Spawn point aim at mouse to shoot

Hi I have a script to shoot projectiles:

 var Bullet : Rigidbody;
 var SpawnPoint : Transform;
      function Fire () {
     // Create a new bullet pointing in the same direction as the gun
         var Shoot = Instantiate(Bullet,SpawnPoint.position,SpawnPoint.rotation);
         Shoot.AddForce(SpawnPoint.forward*5000);
     
          }
          function Update ()
          {
          if (Input.GetMouseButtonDown(0)){
          var hit: RaycastHit;
          var ray = Camera.main.ScreenPointToRay(Input.mousePosition); 
          Fire();
          if (Physics.Raycast(ray, hit)){
          if (hit.collider.CompareTag("beep")){
          hit.collider.gameObject.SendMessage("Damage");
         }
        }
       }
      }

Is it possible to make the spawn point rotate so that I can aim using the mouse? What I want is to have the bullets be aimed at my mouse so I can use it to aim. Thanks.
