title: cvs checkout -c doesn't show all modules
body: <p>I have a module in my repository. Let's call it <code>module1</code>.</p>
  
  <p>If I just checkout it, it's alright, it shows up in my machine and I can work on it.</p>
  
  <p>There's a parameter in checkout command named <code>-c</code> - according to help, '"cat" the module database.'.</p>
  
  <p>But when I run this command</p>
  
  <pre><code>cvs co -c
  </code></pre>
  
  <p>The module isn't showing up. Why? Is there a cache file, something in my machine that needs to be updated, flushes or something? <code>module1</code> <strong>exists</strong>, but doesn't show up when <code>cvs co -c</code> is called. Why?</p>
