replacement for libmysqlclient. mysqlnd will be used to build the
<a href="book.mysql.html" class="link">mysql</a>,
<a href="book.mysqli.html" class="link">mysqli</a>
and <a href="ref.pdo-mysql.html" class="link">PDO_MySQL</a> extensions if libmysqlclient
isn't found on the system. It may also be used instead of libmysqlclient even when
libmysqlclient is present. mysqlnd is recommended for all PHP installations for
performance reasons.
