title: How can I hide the backup files that emacs creates?
body: <p>I just started using emacs after having used vi for a long time. :)</p>
  
  <p>One thing which is annoying me is that whenever I modify a file, save it and exit emacs, I see a backup file created in the same directory named <code>filename~</code> (if the file I edited was <code>filename</code>).</p>
  
  <p>Is there any way I can get rid of this? Or hide these files? It is <em>very</em> annoying to see tons of backup files when I do ls of the directory.</p>
