      Taler is an electronic payment system providing the ability to pay
      anonymously using digital cash.  Taler consists of a network protocol
      definition (using a RESTful API over HTTP), a Exchange (which creates
      digital coins), a Wallet (which allows customers to manage, store and
      spend digital coins), and a Merchant website which allows customers to
      spend their digital coins.  Naturally, each Merchant is different, but
      Taler includes code examples to help Merchants integrate Taler as a
      payment system.
