title: Send URL to Phantomjs?
body: <p><strong>screenshot.js</strong></p>
  
  <pre><code>var page = require("webpage").create();
  var homePage = "http://www.google.com/";
  page.open(homePage);
  page.onLoadFinished = function(status) {
    var url = page.url;
    console.log("Status:  " + status);
    console.log("Loaded:  " + url);
    page.render("google.png");
    phantom.exit();
  };
  </code></pre>
  
  <p><strong>Terminal:</strong></p>
  
  <pre><code>bin/phantomjs screenshot.js
  </code></pre>
  
  <p><strong>Question:</strong>
  Is there any way that I can send phantomjs the URL (value of var homePage above) somehow outside of screenshot.js so that its not hard coded inside the script? </p>
