title: Django error in Heroku: "Please supply the ENGINE value"
body: <p>I read and apply "Getting started with Django on Heroku" tutorial but ran into problem while syncing db:</p>
  
  <pre><code>raise ImproperlyConfigured("settings.DATABASES is improperly configured." 
  django.core.exceptions.ImproperlyConfigured: 
  settings.DATABASES is improperly configured. Please supply the ENGINE value. 
  </code></pre>

While executing</p>
  
  <pre><code>heroku run python manage.py --settings=moz455.settings syncdb
  </code></pre>
  
  <p>I receive error "Unknown command: '--settings=moz455.settings'".
