 * 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 contain 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 dialect has to 
 *      be specified as first;
 *    - 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.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
 * last because we need the default charset to be non-utf-8 to avoid
 * problems on MySQL < 4.1.x if AllowAnywhereRecoding is FALSE.
 *
 * For Russian, we put 1251 first, because MSIE does not accept 866
 * and users would not see anything.
