/**
 * phpMyAdmin Language Loading File
 */

/**
 * All the supported languages have to be listed in the array below.
 * 1. The key must be the "official" ISO 639 language code and, if required,
 * the dialect code. It can also contains some informations about the
 * charset (see the Russian case).
 * 2. The first of the values associated to the key is used in a regular
 * expression to find some keywords corresponding to the language inside two
 * environment variables.
 * These values contains:
 * - the "official" ISO language code and, if required, the dialect code
 * also ('bu' for Bulgarian, 'fr([-_][[:alpha:]]{2})?' for all French
 * dialects, 'zh[-_]tw' for Chinese traditional...);
 * - the '|' character (it means 'OR');
 * - the full language name.
 * 3. The second values associated to the key is the name of the file to load
 * without the '.php' extension.
 * 4. The last values associated to the key is the language code as defined by
 * the RFC1766.
 *
 * Beware that the sorting order (first values associated to keys by
 * alphabetical reverse order in the array) is important: 'zh-tw' (chinese
 * traditional) must be detected before 'zh' (chinese simplified) for
 * example.
 *
 * When there are more than one charset for a language, we put the -utf-8
 * first.
