+Note that PDO on its own is useless.
+You need to install a PDO database driver to make use of it,
+check http://pecl.php.net for a list of available PDO drivers.
+
+It is highly recommended that you update to the latest PHP 5 snapshot before using PDO.
+You can obtain it from http://snaps.php.net.
+
+If you are running on Windows, you should download:
+http://snaps.php.net/win32/php5-win32-latest.zip
+http://snaps.php.net/win32/PECL_5_0/php_pdo.dll
