Php Custom Tag Library

Right now I'm leaning towards the Custom Tags library. One of the best features is support for buried or nested tags like the code block below:

<?php
$current_dir = dirname(__FILE__) . DIRECTORY_SEPARATOR;
require_once $current_dir . 'customtags.php'; 
$ct = new CustomTags(array(
    'parse_on_shutdown' => true,
    'tag_directory' => $current_dir . 'tags' . DIRECTORY_SEPARATOR,
    'sniff_for_buried_tags' => true 
)); 
?> 

<ct:header example_name="Simple Example">Going Well?</ct:header>
