title: Inno Setup Optional (user-selectable) file association
body: <p>In the <a href="http://www.jrsoftware.org/isfaq.php" rel="nofollow">Inno Setup FAQ</a> is an example of how to assign filetypes to my software. Dealing with the registry is no problem.</p>
  
  <p>But how can I provide the user the choice of <strong>which</strong> filetypes he wants to assign? Let's say, I have written a simple editor for text files and want to ask if the user wants to assign .txt and/or .nfo with my program. A setup-page with checkboxes would be genius. </p>
  
  <p>How to do this with Inno Setup?</p>
