title: vim path var, excluding dirs from ** matching
body: <p>One of my favorite vim features is the ability to do</p>
  
  <pre><code>set path=/my/project/root/**
  </code></pre>
  
  <p>and then use</p>
  
  <pre><code>:find SomeClassFile.java
  </code></pre>
  
  <p>Only problem is, I've got some generated directories at that level that I cannot move and wish to exclude from such searches.  I can't seem to figure out how to exclude those dirs.  Anyone know how/if this can be done?</p>
