              <p>This class assumes that PHP has been built with support for FTP. Since the script
                  is straightforward we do not discuss it any more in details other than noting that
                  we use the default system logger to store information that we have uploaded the file
                  successfully. This is done via the PHP method <span class="command"><strong>syslog()</strong></span>.</p>
