-/**
- * Locales represent a specific country and culture.
- *
- * Classes which can be passed a Locale object tailor their information
- * for a given locale. For instance, currency number formatting is
- * handled differently for the USA and France.
- *
- * Locales are made up of a language code, a country code, and an optional
- * set of variant strings.
- *
- * Language codes are represented by
- * ISO 639:1988
- * w/ additions from ISO 639/RA Newsletter No. 1/1989
- * and a decision of the Advisory Committee of ISO/TC39 on
- * August 8, 1997.
- *
- * Country codes are represented by
- * ISO 3166.
- *
- * Variant strings are vendor and browser specific. Standard variant
- * strings include "POSIX" for POSIX, "WIN" for MS-Windows, and "MAC" for
- * Macintosh. When there is more than one variant string, they must
- * be separated by an underscore (U+005F).
- *
- * The default locale is determined by the values of the system properties
- * user.language, user.region, and user.variant.
