== NOTE ON BOX NAMES ==
Dash count indicates level in hierarchy and thus build order -
For instance -
centos-6 <-- base build centos-6-puppet <-- builds on this centos-6-puppet-jenkins <-- builds on centos-6-puppet
== Proxies == Call packer with -var and then http_proxy and https_proxy (and their capitalized counterparts if you like) to build boxes with proxies.
== Environment variables ==
HTTP_PROXY HTTPS_PROXY NO_PROXY BOX_BUILD - set to the name of a build to build only that box during rake spec BOX_OVERRIDE - set to true to have rake spec avoid building each box BOX_FORCE - rebuild packer box even if artifacts are present
