title: Swapping odd/even margin in Latex
body: <p>I'm writing something that I would like to print in Latex and I'm using the <code>book</code> documentclass.</p>
  
  <p>The standard behaviour is to consider odd pages (so the rear of a double sided paper) as the beginning of chapters and document too, I would like to swap them to be able to have correct margins: on an even page right margin is greater than left one, I need the opposite..</p>
  
  <p>Does a simple snippet exist to achieve this thing?</p>
  
  <p>Thanks in advance</p>
