180 * 2. The first of the values associated to the key is used in a regular
181 * expression to find some keywords corresponding to the language inside two
182 * environment variables.
183 * These values contain:
184 * - the "official" ISO language code and, if required, the dialect code
185 * too ('bu' for Bulgarian, 'fr([-_][[:alpha:]]{2})?' for all French
186 * dialects, 'zh[-_]tw' for Chinese traditional...), the dialect has to
187 * be specified first;
188 * - the '|' character (it means 'OR');
189 * - the full language name.
190 * 3. The second value associated to the key is the language code as defined by
191 * the RFC1766.
192 * 4. The third value is its native name in html entities or UTF-8.
194 * Beware that the sorting order (first values associated to keys by
195 * alphabetical reverse order in the array) is important: 'zh-tw' (chinese
196 * traditional) must be detected before 'zh' (chinese simplified) for
197 * example.
