A buildpack that proxies execution to a custom buildpack embedded within an app.
To embedded an app-specific buildpack, create a .buildpack directory in the root of your app
with your buildpack inside. Then set this the Embedded Buildpack Proxy as your app's actual buildpack:
heroku create --stack cedar --buildpack git://github.com/rbrainard/heroku-buildpack-embedded-proxy.git
During the build phases, the Embedded Buildpack Proxy will forward the commands to your own buildpack.
