title: Remove Unused CSS Selectors other than 'Dust Me Selectors'?
body: <p>I would like to remove all unused CSS selectors from a common CSS file. While the Firefox extension "Dust Me Selectors" works well, it only works per page. It reports unused selectors for a page but some could be used on other pages.</p>
  
  <p>Is there a tool which can go through a folder, scan all the files and bring up a list of selectors which are not used anywhere?</p>
