+"""A tool for extracting resource files from an AAR.
+
+An AAR may contain resources under the /res directory. This tool extracts all
+of the resources into a directory. If no resources exist, it creates an
+empty.xml file that defines no resources.
+
+In the future, this script may be extended to also extract assets.
