title: What does "status" in <s:iterator> do?
body: <p>I am using the following command to display values from 'userList' </p>
  
  <pre><code>&lt;s:iterator value="userList" status="rowStatus"&gt;
    &lt;tr class="even"&gt; 
      &lt;td&gt;&lt;s:property value="tweet_id" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;s:property value="message" /&gt;&lt;/td&gt;
      &lt;td&gt;&lt;s:property value="created" /&gt;&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/s:iterator&gt;
  </code></pre>
  
  <p>What is the use of <code>status="rowStatus"</code> in this command?</p>
