FLAGS_HELP="USAGE: build_docker_aci [flags] [docker version] [aci version number].
This script is used to build a CoreOS docker-skim ACI.

The docker version should identify an existent ebuild (i.e.
app-containers/docker-\$version).

The aci version number is an atomically incrementing number that will be
appended to the aci version (to create e.g. :v1.12.6_coreos.0).

Examples:

build_docker_aci --board=amd64-usr --build_dir=<build_dir> 1.12.6 0
