title: Getting the download link for a public Google Docs file
body: <p>Reading the <a href="http://code.google.com/apis/documents/docs/3.0/developers_guide_protocol.html#DownloadingFiles" rel="noreferrer">Google Docs API</a> I find this:</p>
  
  <blockquote>
    <h2>Downloading</h2>
    
    <p>Files cannot be downloaded in a format other than
    the one in which they were originally uploaded. The download URL for
    files looks something like this:</p>
  
  <pre><code>https://doc-04-20-docs.googleusercontent.com/docs/secure/m7an0emtau/WJm12345/YzI2Y2ExYWVm?h=16655626&amp;e=download&amp;gd=true
  </code></pre>
  </blockquote>
  
  <p>Given a public Google Documents file URL, say,</p>
  
  <pre><code>https://docs.google.com/open?id=0B1-vl-dPgKm_NTNhZjZkMWMtZjQxOS00MGE1LTg2MjItNGVjYzdmZjYxNmQ5
  </code></pre>
  
  <p>How can I turn it into a download link?</p>
