<!-- This page's main aim is to show to the customer all the accepted payments methods
and actually implementing just Taler; technically the steps are:
1. retrieve the name of who will receive this donation
2. show a menu with all the required payments means
3. create a session
4. (JavaScript) implement the "checkout" button for the sole Taler way.
Actually, this button's duty is to notice this web portal that the customer
wants to see a certificate, and optionally to pay.
