// Below is the recommended way to load PHP DNS, with individual
// classes:
use PurplePixie\PhpDns\DNSQuery;

require_once __DIR__ . '/src/PurplePixie/PhpDns/DNSAnswer.php';
require_once __DIR__ . '/src/PurplePixie/PhpDns/DNSQuery.php';
require_once __DIR__ . '/src/PurplePixie/PhpDns/DNSResult.php';
require_once __DIR__ . '/src/PurplePixie/PhpDns/DNSTypes.php';

// Here is the legacy way (single file to load classes) BUT must
// now also have the namespace line:
/*
require_once("dns.inc.php");
use PurplePixie\PhpDns\DNSQuery;
