/**
* phpMyAdmin Language Loading File
*/
/**
* 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 contains 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 '|' 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 '.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
* first.
