  -Cloud Foundry buildpacks can work with limited or no Internet connectivity. The [Buildpack Packager](https://github.com/cloudfoundry-incubator/buildpack-packager) RubyGem gives the same flexibility to custom buildpacks, enabling them to work in partially or completely disconnected environments.

positive.code: $ cf push my-new-app -b https://github.com/johndoe/my-buildpack#v1.4.2
  </pre>
  
  The app will then be deployed to Cloud Foundry, and the buildpack will be cloned from the repository and applied to the app.
  
   <p class="note"><strong>Note</strong>: If a buildpack is specified using `cf push -b` the `detect` step will be skipped and as a result, no buildpack `detect` scripts will be run.

negative.code: * To make use of dependencies provided by the previously applied buildpacks, the last buildpack must scan `/tmp/deps/` for index-named directories containing `config.yml.` 
  * To make use of dependencies provided by previous buildpacks, the last buildpack:
  	* May use `/bin` during staging, or make it available in $PATH during launch
  	* May use `/lib` during staging, or make it available in $LD\_LIBRARY\_PATH during launch
  	* May use `/include`, `/pkgconfig`, or `/env` during staging
  	* May copy files from `/profile.d` to `/tmp/app/.profile.d` during staging
  	* May use the supplied config object in `config.yml` during the staging process
