title: How to check the version of a installed application in Django in running time?
body: <p>I basically need to know the version of an specific application that it is installed and added to</p>
  
  <pre><code>INSTALLED_APPS = (
      ...
      'the_application',
      ...
  )
  </code></pre>
  
  <p>I know that I can use pip freeze. I know the version of the application in my current virtual environment. </p>
  
  <p>The problem is I want to support two versions of the_application.</p>
  
  <p>Something like settings.INSTALLED_APP['the_application'].get_version() would be what I am looking for...</p>
