   The Go buildpack supports building with C dependencies using [cgo](https://golang.org/cmd/cgo/). You can set config vars to specify cgo flags
  -to, for example, specify paths for vendored dependencies. As an example, to build [gopgsqldriver](https://github.com/jbarham/gopgsqldriver), 
  -add the config var `CGO_CFLAGS` with the value `-I/app/code/vendor/include/postgresql`

  ### <a id='with_glide'></a>Push an App with Glide ###
  If you use [glide](https://github.com/Masterminds/glide) to specify or package your dependencies, 
  make sure that you have created a valid `glide.yml` 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. 
  You must have a `glide.lock` file when pushing a vendored app. You do not need a `glide.lock` file when deploying a non-vendored app.

  ## <a id='passing_symbol_linker'></a>Pass a Symbol and String to the Linker ##
  
  The Go buildpack supports the Go [linker's](https://golang.org/cmd/link/) ability, `-X symbol value`,
  to set the value of a string at link time.
  Set the `GO_LINKER_SYMBOL` and `GO_LINKER_VALUE` in the application's configuration  before pushing code.
