   The Go buildpack will be automatically detected if:
   
  -- your app has been packaged with [godep](https://github.com/tools/godep) using `godep save`
  -- your app has a `vendor/` directory and has any files ending with `.go`.
  -- your app has a `GOPACKAGENAME` environment variable specified and has any files ending with `.go`.

   If your Cloud Foundry deployment does not have the Go Buildpack installed, or the installed version is out of date, you can use the latest version with the command:

  ### <a id='with_glide'></a>Pushing Apps with glide ###
  If you are using [glide](https://github.com/Masterminds/glide) to specify and/or package your dependencies, make sure that you have created a valid `glide.yaml` file in the root directory of your app by running `glide init`.
  
  To vendor your dependencies before pushing, run `glide install`. This will generate a `vendor` directory and a `glide.lock` file specifying the latest compatible versions of your dependencies. A `glide.lock` is not required when deploying a non-vendored app. A `glide.lock` is required when pushing a vendored app.

  If you are using the native Go vendoring system, which packages all local dependencies in the `vendor/` directory, you must specify your app's package name in the `GOPACKAGENAME` environment variable. An example `manifest.yml`:
  
  ```yaml
