title: Ant strings comparison
body: <p>I have a script in ant, and I need to compare 2 strings lexicographically.
  something like:</p>
  
  <pre><code> "1.2.3".compareTo("1.2.4")
  </code></pre>
  
  <p>I can't find a way to do so... Any ideas? I'm using ant 1.8, and ant-contrib.</p>
  
  <p>Thanks</p>
