class_docstr: On Unix/Linux, we follow the
  `XDG Basedir Spec <https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html>`_. The spec allows
  overriding directories with environment variables. The examples show are the default values, alongside the name of
  the environment variable that overrides them. Makes use of the
  `appname <platformdirs.api.PlatformDirsABC.appname>`,
  `version <platformdirs.api.PlatformDirsABC.version>`,
  `multipath <platformdirs.api.PlatformDirsABC.multipath>`,
  `opinion <platformdirs.api.PlatformDirsABC.opinion>`.
code: def _first_item_as_path_if_multipath(self, directory: str) -> Path:
      if self.multipath:
          # If multipath is True, the first path is returned.
          directory = directory.split(os.pathsep)[0]
      return Path(directory)
