title: Celery Python logging config to log DEBUG only from specified modules
body: <p>I'm trying to get django celery to log (to console) DEBUG (and higher) events coming from my modules (and not those of libraries). So starting celeryd with:</p>
  
  <pre><code>python hack/manage.py celeryd -E -l DEBUG -c 2
  </code></pre>
  
  <p>will mean that all DEBUG events are passed to console (which is a handler on my root logger). I'd like to modify this behaviour so that:</p>
  
  <ul>
  <li>DEBUG events from mymodule (and children) go to console</li>
  <li>DEBUG events from all other modules are ignored (eg: go to the Null Handler)</li>
  <li>all other events are processed as normal (eg: ERROR continues to go to the mail handler)</li>
  </ul>
  
  <p>What is the best way to do this?</p>
