# 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 script is intented to be run as part of a docker build, as defined in the Dockerfile at the root of the source.
# - If you don't call this script from the official Dockerfile, or a container built by the official Dockerfile, you're probably doing it wrong.
