* in '*', not in MATCH_FILE). If an exact '\' character is to be matched
* the source string must contain a '\\'. sequence.</li>
*
* </ul>
*
* <p>When more than two '*' characters, not separated by another
* character, are found their value is considered as '**' (MATCH_PATH).
* <br> The array is always terminated by a special value (MATCH_END).

* equal or greater.</p>
