    md5 << File.read('Gemfile')
    checksum = md5.hexdigest
    installed = File.read('.bundle/checksum').strip

* We add script/cibuild to most projects. Lets us keep test config in the repository.

    # set env vars
    export RACK_ROOT=["..."]
    export RACK_ENV="test"
    # load gc ocnfig
    # clean work dir
    script/bootstrap
    bin/rake

# gh-setup <project>
* apps:  dropbox + homebrew + chrome + 1password + etc.
* dependencies: mysql + node + redis + riak  + postgres + rbenv  + etc.
* config: disk encryption + vpn + screen locks + etc.
* puppet

# deploy locking (hubon + heaven)
* you push a branch
* ci starts a build
* build passes
* you deploy branch
* 'heaven' prevents deploy conflicts
* you merge branch
* 'heaven' unlocks deploys
