+# DinD: a wrapper script which allows docker to be run inside a docker container.
+# Original version by Jerome Petazzoni <jerome@docker.com>
+# See the blog post: https://blog.docker.com/2013/09/docker-can-now-run-within-docker/

+# This script should be executed inside a docker container in privilieged mode
+# ('docker run --privileged', introduced in docker 0.6).
+
+# Usage: dind CMD [ARG...]
+
+# apparmor sucks and Docker needs to know that it's in a container (c) @tianon
+export container=docker
