* 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 contain:
* - 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.
