Setting Quantity on Product within Shopping Cart

AWDR depot example always sets quantity to 1 when it adds a product to
the cart. Is there an example anywhere which lets the user set quantity
to whatever as it adds the product.

I cant see letting a user add a product and if they want a quantiy of
"3" they have to add the same product 3 times. Not very user friendly.

Again if any one can point me to a sample ... much appreciated.
