title: RRULE to human readable text
body: <p>I want to generate a human readable text (natural language) from a RRULE string (<a href="http://www.ietf.org/rfc/rfc2445.txt" rel="nofollow">RFC2445</a>). I have googled for it, what I have found is only a JavaScript library (<a href="https://github.com/jakubroztocil/rrule" rel="nofollow">rrule.js</a>) which can generate such a text. But I need this functionality in Android (Java).</p>
  
  <p>Is there a library wrriten in Java like this ? If not, I heared about a couple of JavaScript engines in Java (Rhino for example) But I'm very worry about my Android app performace because It seems this engines is a bit heavy weight.</p>
