  """The GoCardless Python Client Library
  
  This module provides a wrapper around the GoCardless payments API, the
  interface to the api is provided by the :py:class:`gocardless.Client`
  object. See the documentation for that class for how to obtain a reference.
  
  By default the library will attempt to use the GoCardless production
  environment, for testing purposes this is not what you want and you
  should set the :py:data:`gocardless.environment` to "sandbox".
  
  Once you have obtained an instance of a client you can use that client
  to generate urls for receiving payments. You can also use it to query
  the api for information about payments resources using an active resource
  style API. For example, to get all of a merchants bills:
  
  .. code-block:: python
  
      >>> merchant = client.merchant()
      >>> merchant.bills()
      >>> [<gocardless.resources.Bill at 0x29a6050>]
