what the purpose of the in the AndroidManifest.xml

Question

A default delphi AndroidManifest.xml is like this :

<?xml version="1.0" encoding="utf-8"?>
<!-- BEGIN_INCLUDE(manifest) -->
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.embarcadero.Project1"
        android:versionCode="1"
        android:versionName="1.0.0"
        android:installLocation="auto">    
  ....

</manifest>
<!-- END_INCLUDE(manifest) -->

What the purpose of the <!-- BEGIN_INCLUDE(manifest) --> and <!-- END_INCLUDE(manifest) --> comment ?
