oscommerce/creloaded attach invoicie to email

Hello, What i am wanting to do is have is when an order is placed, I was wanting to have the invoice and/or packing slip attached to the email thats sent to the store admin as html files. Needs to be a way i can comment out either or both in the code. I am also using this mod [login to view URL] which i would also want the proper xml file attached to this email to me. So if someone selected ground i would need the ground xml generated and attached. So for a ups order i would get 3 attachements, invoice, packing slip and xml usps and other orders woiuld only get the invoice and packing slip.
