title: How do I override the review tab on OnePage Checkout
body: <p>I am writing a custom module to change the display of the table on checkout/onepage/onepage.phtml I can see in checkout.xml how it gets declared with</p>
  
  <pre><code>&lt;block type="checkout/onepage_review" name="checkout.onepage.review" as="review" template="checkout/onepage/review.phtml"&gt;
       &lt;block type="checkout/agreements" name="checkout.onepage.agreements" as="agreements" template="checkout/onepage/agreements.phtml"/&gt;
  &lt;/block&gt;
  </code></pre>
  
  <p>What I can not figure out is how to set up the /app/design/frontend/{location}/{theme}/layout/{module}.xml file to override the current review.phtml template with the new one. My thought would be to remove the current one and reload with the new one but that doesn't seem to be working.  </p>
