        This rules file is meant to be imported by the custom Ant task:
            com.android.ant.AndroidInitTask

        The following properties are put in place by the importing task:
            android.jar, android.aidl, aapt, aidl, and dx

        Additionnaly, the task sets up the following classpath reference:
            android.target.classpath
        This is used by the compiler task as the boot classpath.
