  # Optionally, you can pass in an alternative to the root path '/' which is used when building the path
  # to the config file. In the code snippet below, the method will create any directories and files relative to the
  # provided root path. For example, in the snippet below, the method will create the spoor config file in
  # /tmp/etc/spoor rather than /etc/spoor. This is primarily used to support testing.
