 * 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).
 *    These code are displayed at the starting page of phpMyAdmin.
 * 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 'inc.php3' 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.
