title: Performing permissions change ala chmod / attrib with Powershell
body: <p>I would like to do the equivalent of <code>chmod -w+r-x foo</code> or <code>attrib +R foo</code> in Windows Powershell. Putzing around, I notice a fairly gnarly <code>Set-Acl</code> function that looks <em>significantly</em> fancier than what I need. </p>
  
  <p>How do I do <code>attrib +R foo</code> in Windows Powershell?</p>
