positive.code: * `bin/compile` deprecated alternative to `bin/supply` and `bin/finalize`
  
  The `bin/supply` and `bin/finalize` scripts replace the deprecated `bin/compile` script.
  Older buildpacks may still use `bin/compile` with the latest Cloud Foundry, but without support for applying multiple buildpacks to a single application.
  Similarly, newer buildpacks may still provide `bin/compile` for compatibility with Heroku and older versions of Cloud Foundry.
  
  The `bin/supply` script is required for non-final buildpacks. The `bin/finalize` (or `bin/compile`) compile script is required for final buildpacks.

negative.code: 
  ### <a id='finalize-script'></a>bin/finalize ###
  
  The `finalize` script prepares the app for launch and runs only for the last buildpack. All output sent to `STDOUT` is relayed through the Cloud Foundry CLI to the user.
  
  The script is run with four arguments:
  
  * The `build` directory for the app
  * The `cache` directory, which is a location the buildpack can use to store assets during the build process
  * The `deps` directory, which is where dependencies provided by all buildpacks are installed
  * The `index`, which is a number that represents the ordinal position of the buildpack
  
  The `finalize` script may find dependencies installed by the same buildpack's `supply` script in `deps`/`index`. It may also look in other directories within `deps` to find dependencies supplied by other buildpacks.
  
  The `cache` directory provided to the `finalize` script is preserved even when the buildpack is upgraded or otherwise changes. The same buildpack's `supply` script also has access to this cache directory.
