title: Accessing the process / environment from a grunt template
body: <p>I have some code in a grunt.js file which is working with 0.3 but breaks on 0.4:</p>
  
  <pre><code>{
      dest: '&lt;%= process.env.DEST %&gt;/index.html'
  }
  </code></pre>
  
  <p>In 0.3 process is defined and so I can access variables defined in the environment inside the template when I am e.g. passing file paths to other plugins.</p>
  
  <p>Is there an alternative approach to this which will work in 0.4? Or a way to put a breakpoint in while the template is rendering so that I can see what variables are available?</p>
