PHP manual in a PHP course

Hi, I maintain a PHP course, I want to add something that talks about try/catch. To do this properly I would need to show the built in exception class, this is Example #2 on page: http://jp.php.net/manual/en/language.exceptions.php What permission/... do I need to reproduce just this, the exception class definition ? The rest of the course material is original.
