          Note:
              Don't rely on the country name when working with several instances of
              py:class:`Callinfo`. Clublog and Country-files.org use slightly different names
              for countries. Example:
  
              - Country-files.com: "Fed. Rep. of Germany"
              - Clublog: "FEDERAL REPUBLIC OF GERMANY"
