title: Zend Framework code documentation style
body: <p>I was wondering why there's two blocks of comments with repeated information. Does someone knows the answer?</p>

  <p>For example: @category, @package, @copyright, @license. Those repeat twice on the first  and second comment block.</p>
  
  <p>I was looking for the commenting best practices and while analyzing their code, I've came up with this question.</p>
  
  <p>Please, do not blame me if it's too much simple.</p>
