Environment variables are available both at run time and during the application build/compilation step for buildpack-based deploys.
For buildpack deploys, Dokku will create a `/app/.env` file that can be used for legacy buildpacks. Note that this is *not* updated when `config:set` or `config:unset` is called, and is only written during a `deploy` or `ps:rebuild`. Developers are encouraged to instead read from the application environment directly, as the proper values will be available then.

> Note: Global `ENV` files are sourced before app-specific `ENV` files. This means that app-specific variables will take precedence over global variables. Configuring your global `ENV` file is manual, and should be considered potentially dangerous as configuration applies to all applications.
