""" Locale support.
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.
