title: How can I debug a Vim plugin not being loaded?
body: <p>I'm trying to use the Vim snipMate plugin, and I've installed it as it directs, but when I press tab nothing happens.</p>
  
  <ul>
  <li>How can I debug this? Are there log files Vim makes when it tries to load stuff?</li>
  <li>How can I see what plugins its loaded correctly?</li>
  </ul>
  
  <p>I've tried <code>:sni&lt;tab&gt;</code> to see if there's anything called snipsomething installed but nothing completes.</p>
  
  <p>In the installation tutorial it doesn't mention adding anything into my <code>vimrc</code> but I guess it finds the <code>/plugin/</code> dir automatically?</p>
  
  <p>I'm running on Windows and Unix and I have the same profile with the same problem.</p>
  
  <p>Other plugins like NerdTree are loading OK.</p>
  
  <p><strong>Update:</strong> Following another question, I've tried <code>:inoremap</code> and <code>:snoremap</code> and the <code>&lt;Tab&gt;</code> entry mentioning <code>TriggerSnippet()</code> is there:</p>
  
  <p>e.g.</p>
  
  <pre><code>s &lt;Tab&gt;   * &lt;Esc&gt;i &lt;Right&gt;&lt;C-R&gt;=TriggerSnippet()&lt;CR&gt;
  </code></pre>
  
  <ul>
  <li>Does this mean it's enabled?</li>
  </ul>
