About System-Locale

This library retrieves locale information configured on the system. This is helpful if you want to write applications and libraries that display messages in the user's native language.

How To

(system-locale:locale)   ; => "en_GB.UTF-8"
(system-locale:language) ; => "en"

The functions discover-active-locales and discover-active-languages describe how the locale and language discovery is handled.
