 /**
  * Import Target Ant task. This task accomplishes:
  * <ul>
  * <li>Gets the project target hash string from {@link ProjectProperties#PROPERTY_TARGET},
- * and resolves it.</li>
- * <li>Sets up ant properties so that the rest of the Ant scripts finds:
- *    <ul>
- *       <li>Path to the underlying platform to access the build rules ('android-platform')<li>
- *    </ul>
- * </li>
+ * and resolves it to get the project's {@link IAndroidTarget}.</li>
+ * <li>Sets up properties so that aapt can find the android.jar in the resolved target.</li>
+ * <li>Sets up the boot classpath ref so that the <code>javac</code> task knows where to find
+ * the libraries. This includes the default android.jar from the resolved target but also optional
+ * libraries provided by the target (if any, when the target is an add-on).</li>
+ * <li>Imports the build rules located in the resolved target so that the build actually does
+ * something.</li>
  * </ul>
  * 
  * This is used in build.xml/template.
