<h3><a name="LOCAL_MODULE_TAGS" id="LOCAL_MODULE_TAGS"></a>LOCAL_MODULE_TAGS</h3>
<p>This variable controls what build flavors the package gets included in. For example:</p>
<ul type="disc">
  <li>user - means include this in user/userdebug builds</li>
  <li>eng - means include this in eng builds</li>
  <li>tests - means the target is a testing target and makes it available for tests</li>
  <li>optional - don't include this</li>
</ul>
