Order Notification Layout

I want to add the customer Purchase Order Number n the order notification. How do i do that?

I imagine it would be similar to the way in which you add the Shipping method and Payment method to the customer's confirmation email.
That requires editing OrderScript.pl and adding a line to the Buyer or Customer email.
Details are in the AUG for Shipping and Payment - you would need to get the exact code for PurchaseOrderNumber.
