title: Download source code from Apple's website
body: <p>How do I download source code from Apple's website (http://opensource.apple.com/source/).
  In particular, I am interested in <a href="http://opensource.apple.com/source/Security/Security-55110/">http://opensource.apple.com/source/Security/Security-55110/</a>.</p>
  
  <p><code>wget -r</code> is downloading HTML files instead of source files. Thanks!</p>
