title: shutil.rmtree to remove files only?
body: <p>I am using <code>shutil.rmtree</code> to remove a directory, but other processes (that I don't control) that create files in that tree are failing to create the files because the directories don't exist. Is there something as easy as <code>shutil.rmtree</code> that only deletes files but preserves directory structure?</p>
