title: How to avoid removing directory on remove_all with Boost Libraries?
body: <p>I'm using boost::filesystem::remove_all operation to remove the content of a directory. </p>
  
  <p>It removes correctly the content, but, as state by Boost Filesystem Documentation, it also removes the directory itself. </p>
  
  <p>Is there an easy way to stay with the directory despite that it's empty?</p>
