title: variable in setting file using in template
body: <p>everybody! I want to access to constants value that I declare in my setting.py file to use in my template, but not in a template inside the app, I just want to use in my home template the template that I declare in my setting file.</p>
  
  <pre><code>CMS_TEMPLATES = (
      ## Customize this
      ('page.html', 'Page'),
      ('feature.html', 'Page with Feature'),
      ('homeTemplate.html', 'Home Template') // I want to use here
  )
  </code></pre>
  
  <p>I found <a href="https://stackoverflow.com/questions/433162/can-i-access-constants-in-settings-py-from-templates-in-django">this</a> example about the same problem in StackOverflow, but all case uses the variable inside apps not in top level.</p>
  
  <p>How is the best way to use this value inside this template!!</p>
