title: Can you selectively load fixtures in symfony2
body: <p>When I run</p>
  
  <pre><code>console doctrine:fixtures:load --fixtures=src/App/PeopleBundle/DataFixtures/ORM
  </code></pre>
  
  <p>I don't want doctrine to purge every table that has an entity. Instead, I only want to purge tables for the fixtures that are in the explicitly specified directory.</p>
  
  <p>However, it seems that, regardless of the target directory, symfony is finding every entity in every bundle, and purging every table associated with each entity.</p>
  
  <p>How can I direct symfony2 to ignore all tables except for the specific tables for which I have written fixtures?</p>
