title: ClearCase: How to find elements that do NOT have a particular label
body: <p>I'm looking for a ClearCase command that will list all the elements that are visible in my current view, but do <strong>NOT</strong> have a particular label applied to them.</p>
  
  <p>Say for example, most of the elements that are visible in my view have <em>LABEL_X</em> applied to them.  I want a list of those elements that do not have <em>LABEL_X</em>.</p>
  
  <p>I obviously need to use <code>cleartool find</code>, but the usage and ClearCase man page baffle me in terms of how to construct a query like this.</p>
