# This script builds various binary artifacts from a checkout of the docker
# source code.
#
# Requirements:
# - The current directory should be a checkout of the docker source code
# (http://github.com/dotcloud/docker). Whatever version is checked out
# will be built.
# - The VERSION file, at the root of the repository, should exist, and
# will be used as Docker binary version and package version.
# - The hash of the git commit will also be included in the Docker binary,
# with the suffix -dirty if the repository isn't clean.
# - The script is intented to be run as part of a docker build, as defined
# in the Dockerfile at the root of the source. In other words:
# DO NOT CALL THIS SCRIPT DIRECTLY.
# - The right way to call this script is to invoke "docker build ." from
# your checkout of the Docker repository.

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."
