title: What's the option of tar that corresponds to the `arcname` option in Python `tarfile` module?
body: <p>In Python, we can specify an alternative name for a file in the archive:</p>
  
  <pre><code>with tarfile.open('archive.tar', 'w') as a:
      a.add('files', arcname='another_name')
  </code></pre>
  
  <p>This is done with the <code>arcname</code> parameter.</p>
  
  <p>Now I'm trying to do the same thing with plain <code>tar</code> command, but I can't find the option that let me specify an alternative name.</p>
