title: Any way to use a custom diff tool with cleartool/clearcase?
body: <p>I'd like to use my own diff when working in a clearcase snapshot view.  </p>
  
  <p>As far as I can see, there is no way to specify a diff tool when running "<code>cleartool diff</code>", so I was thinking I could run something like "<code>mydiff &lt;predecessor file&gt; &lt;modified file in my view&gt;</code>", but I don't know enough about ClearCase to be able to find the "predecessor file" to diff against.  </p>
  
  <p>Any way to do this?</p>
  
  <p>Forgot to mention (until now, after reading the first two responses dealing with windows) that this is on Unix, and I am not allowed to muck with the ClearCase configuration.</p>
