title: Easy way to add a context action to Eclipse
body: <p>I'm trying to add a very simple action to the context menu of Eclipse: clicking with right button over a folder object, this action should call an external tool (configured in the "External Tools") using the path of the folder as the only parameter.</p>
  
  <p>I've found a <a href="http://www.eclipse.org/articles/article.php?file=Article-action-contribution/index.html" rel="nofollow noreferrer">tutorial on how to add a context menu</a>, but it's more complex than what I need -- I don't really want to create a plugin, I don't even want to create classes to do what I want. My only purpose is to call an external tool.</p>
  
  <p>How can I do it?</p>
