title: How does one use Django custom management command option?
body: <p>The Django doc tell me how to add an option to my django custom management command, via an example:</p>
  
  <pre><code>from optparse import make_option
  
  class Command(BaseCommand):
      option_list = BaseCommand.option_list + (
          make_option('--delete',
              action='store_true',
              dest='delete',
              default=False,
              help='Delete poll instead of closing it'),
      )
  </code></pre>
  
  <p>Then the docs just stop. How would one write the <code>handle</code> method for this class to check whether the user has supplied a <code>--delete</code> option? At times Django makes the easy things difficult :-(</p>
