<h2>Description</h2>
This example shows a client that:
<ul>
  <li>logs into manager</li>
  <li>gets information on all components</li>
  <li>logs out of manager</li>
</ul>
<br>
<br>
<h2>What can I gain from this example?</h2>
<ul>
  <li>SimpleClient usage.</li>
  <li>Using manager directly through SimpleClient.</li>
  <li>The knowledge that a manager reference can be used for more than just getting component references.</li>
  <li>ACS logging mechanisms.</li>
</ul>
