title: How to get the description of a command without running it, using its name?
body: <p>If I use a command like this one:</p>
  <pre><code>class ImportFilesCommand extends ContainerAwareCommand
  {
      protected function configure()
      {
          $this
              -&gt;setDescription('A text describing my command.')
              -&gt;setName('app:import:files')
              );
      }
  </code></pre>
  <p>Is it possible to get the description <em>'A text describing my command.'</em> using the name of the command <code>app:import:files</code>, without executing the command?</p>
  <p>I would use this inside a controller.</p>
