title: How do I log Scrapy settings?
body: <p>Scrapy gets its settings from a number of sources -- environment parameters, a configuration file, programmatic settings -- so I want to log the effective settings to see what it's got.</p>
  
  <p>How do I do that?</p>
  
  <p>I would simply iterate over keys and values in Scrapy's  Settings object, but it does not expose the full interface of a dict as one might expect.</p>
