title: How to register multiple models with the admin?
body: <p>If I want to register my models with the admin I have to do this like this:</p>
  
  <pre><code>#admin.py
  admin.site.register(models.About)
  </code></pre>
  
  <p>But with multiple models you <strong>can't</strong> do something like this:</p>
  
  <pre><code>models = (models.Project, models.Client, models.About)
  for m in models:
     admin.site.register(m)
  </code></pre>
  
  <p>First of all: why not!? Secondly: imagine one has a lot of models which all should be accessible from the admin interface. How do you do that in a generic way? </p>
