title: Vim - editing tar and tgz files
body: <p>I'm embarrassed to say, after a couple of decades of using vim, I've only just discovered you can open, browse, and look at tar, and tgz files in vim (although in fairness, I think that this is quite a recent add-on)</p>
  
  <p>(<em>if you haven't discovered this feature yet by the way, it's very cool</em>) </p>
  
  <p>Does anyone know if one can <strong>edit</strong> files the files in tar files, and have vim repack them back into the archive.</p>
  
  <p><a href="http://www.vim.org/scripts/script.php?script_id=522" rel="nofollow noreferrer">The plugin page</a> and <a href="https://stackoverflow.com/questions/8873716/vim-how-can-i-create-a-file-after-vim-file-tgz">This SO question</a> Seems to suggest it's read only, but I wondered if there was a way to do this. </p>
