      The module provides low-level access to the C lib's locale APIs
      and adds high level number formatting APIs as well as a locale
      aliasing engine to complement these.
  
      The aliasing engine includes support for many commonly used locale
      names and maps them to values suitable for passing to the C lib's
      setlocale() function. It also includes default encodings for all
      supported locale names.
