title: Is KCFinder a legal alternative to CKFinder
body: <p>On the one hand there is <a href="http://ckfinder.com/" rel="nofollow noreferrer">http://ckfinder.com/</a></p>
  
  <p>CKFinder or the people behind it have always been very vague about their licenses when we asked information about them, so we aren't really fond of using their commercially licensed products.</p>
  
  <p>So I've looked for an alternative and found <a href="http://kcfinder.sunhater.com" rel="nofollow noreferrer">http://kcfinder.sunhater.com</a> which comes with an LGPL license, perfect for use in a commercial application that just wants to use the file browser and not modify it.</p>
  
  <p>Now they both look very similar and my question is: is KCfinder a legal alternative to CKfinder? Or is it an exact and modified copy?</p>
  
  <p>Does anyone know this or can find this out?</p>
