Only Abstract on page.tpl.php with the following function

I am using the following code in my page.tpl.php

<?php
	    if (function_exists('nodewords_get')) {
	      $metatags = nodewords_get('node', $node->nid);
	    }
	  ?>	<?php
	      foreach ($metatags as $tagname => $tagcontent) {
	        print "<dt>$tagname</dt>";
	        print "<dd>$tagcontent</dd>";
	      }
	    ?>

it works fine but I want to edit that code so only "abstract" is printed, I would really appreciate some feedback
