    * `:validate_compile_env` - by default a release will match all runtime
      configuration against any configuration that was marked as compile time

  Often it is necessary to copy extra files to the release root after
  the release is assembled. This can be easily done by placing such
  files in the `rel/overlays` directory. Any file in there is copied

  is to the release root. If you need to copy files dynamically, see
  the "Steps" section.
