+There is no manifest that contains exactly those. However, there
+are manifests that allow building those components. The following
+commands work for 3.0_r1.1, and using other versions can be done by
+switching the git checkout paramater, and if necessary the -b parameter in
+repo init.
+
+ $ repo init -b master -m 3.0-base.xml
+ $ repo sync
+ $ repo forall -c git checkout android-3.0_r1.1
