Examples container type is designed to keep applications using codezero userspace libraries, which is aiming to help newcomers who would like to develop programs on top of the l4 microkernel. Now bare bone application is one of the examples. In the near future, lots of new programs will be introduced to show the various aspects of codezero eco-system.
