     *    - the "official" ISO language code and, if required, the dialect code
     *      too ('bu' for Bulgarian, 'fr([-_][[:alpha:]]{2})?' for all French
     *      dialects, 'zh[-_]tw' for Chinese traditional...), the dialect has to
     *      be specified first;
     *    - the '|' character (it means 'OR');
     *    - the full language name.
     * 3. The second value associated to the key is the name of the file to load
     *    without the 'inc.php' extension.
     * 4. The third value associated to the key is the language code as defined by
     *    the RFC1766.
     * 5. The fourth value is its native name in html entities.
     *
     * 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.
