title: Where can I find a Nassi-Shneiderman Diagram Editor?
body: <p>I have to do some work for college and my professor likes to torture us with Nassi-Shneiderman diagrams. </p>
  
  <p>Has anyone a good editor/graphcial tool to draw these? Requirements:</p>
  
  <ul>
  <li>cross platform (or able to run within wine)</li>
  <li>open source (or a least free to for private use)</li>
  </ul>
  
  <p>--</p>
  
  <p>After considering some editors, I ended up by using Strutorizer from <a href="http://structorizer.fisch.lu/" rel="nofollow noreferrer">http://structorizer.fisch.lu/</a></p>
  
  <p>It hasn't the best usability but it's good enough. And it's written in Java.</p>
