PACKAGE_DESCRIPTION="lxc-docker is a Linux container runtime
Docker complements LXC with a high-level API which operates at the process
level. It runs unix processes with strong guarantees of isolation and
repeatability across servers.
Docker is a great building block for automating distributed systems:
large-scale web deployments, database clusters, continuous deployment systems,
private PaaS, service-oriented architectures, etc."
