title: commander.js - .prompt removed, now what?
body: <p>In <a href="https://github.com/visionmedia/commander.js">commander.js</a>, when asking for user input, I would use the prompt method:</p>
  
  <pre><code>program.prompt('name: ', function(name){
    console.log('hi %s', name);
  });
  </code></pre>
  
  <p>But now that method has been removed in version 2.0.0. What is the new method to ask for user input?</p>
