title: Clearcase "pname" for a VOB
body: <p>I'm trying to change the ownership on a VOB, and I see that the <code>cleartool protect</code> command has a <code>chown</code> option.  It's asking for a pname, and I can't seem to find documentation on what a pname is or how to specify one.  I guess my questions boil down to:</p>
  
  <ol>
  <li><p>What's a pname?  What's its format?</p></li>
  <li><p>How do I specify the pname for a VOB?</p></li>
  <li><p>Is there documentation on pnames somewhere?  Or at least examples of changing ownership of VOBs.</p></li>
  </ol>
