  banner <<-USAGE
      To generate a Targeted @Pay Button, follow these steps:
      Create a text file, e.g. data.txt, containing an email address and the associated credit card token separated by a comma. Enter multiple lines for multiple buttons:

      test1@example.com,TL1UwJFXVN7e4p6+0B5N8hy4qQyqeNxVllmC663MLcMupuAWXdHJ9g8PRAnlIh+AMZBgpaIrfWStZ5/3hYi6vCAV7q6+3M6LLqxk
      test2@example.com,XKCF2E9QZPwdOSwfTQJzZC7byLt3PH8Tr1KhmLkfRHwfNJD5XbDRMrxGYOiSnfrLEKNzm9+a4r++bpUG2hNrPyYLpNgph3BXAAfC

      Then run the following from the console in the same location as the file you created:

      $ atpay_buttons --title "Pay" --amount 50.00 --subject "Payment for fifty bucks" --private-key "plBs9X+Zvr65z6iCa0oLNdAEGYZ85Dzf74Qy1yPTris=" --public-key "06zK82iu9NUUMmDiZsEvoUH25tbIE6R3R+zPnDK8YGQ=" --partner-id 20 --input data.txt



      To generate a Universal @Pay Button, run the following command:

      $ atpay_buttons --universal true --title "Pay" --amount 50.00 --subject "Payment for fifty bucks" --private-key "plBs9X+Zvr65z6iCa0oLNdAEGYZ85Dzf74Qy1yPTris=" --public-key "06zK82iu9NUUMmDiZsEvoUH25tbIE6R3R+zPnDK8YGQ=" --partner-id 20
