title: Accurev: how to ignore contents of a directory but not the directory
body: <p>I have a "project" directory which has an .acignore file containing:</p>
  
  <p>out/*</p>
  
  <p>The "project" directory contains the checked-in "out" directory. But i want to ignore anything in the "out" directory tree.</p>
  
  <p>The above doesn't seem to work. What's the right syntax?</p>
  
  <p>Thanks.</p>
