title: add site links to magento template files
body: <p>What is the best way to add a link to a Magento template file?</p>
  
  <p>At the moment I'm using the below method but I'm wondering if there is a better way which calls a native magento method?</p>
  
  <pre><code>&lt;a href="about-us"&gt;&lt;?php echo $this-&gt;__('About Us'); ?&gt;&lt;/a&gt;
  &lt;a href="checkout/cart"&gt;?php echo $this-&gt;__('Shopping Bag'); ?&gt;&lt;/a&gt;
  </code></pre>
  
  <p>I know you can use <code>&lt;img src="&lt;?php echo $this-&gt;getSkinUrl('images/test.png');?&gt;" /&gt;</code> to get an image url, is there something similar for links?</p>
