title: Get current page using PrawnPDF
body: <p>does anyone know if there is a method to get the <strong>current page</strong> on PrawnPDF for Ruby on Rails? I'm using <code>PrawnPDF (0.12.0)</code> with <code>Rails 3.2.9</code>. I've looked in the documentation, without success.</p>
  
  <p>Thanks a lot!</p>
