      This is the dataset from :footcite:`DufauEtAl2015`.
  
      Parameters
      ----------
      path : None | str
          Location of where to look for the kiloword data storing
          location. If None, the environment variable or config parameter
          MNE_DATASETS_KILOWORD_PATH is used. If it doesn't exist,
          the "mne-python/examples" directory is used. If the
          kiloword dataset is not found under the given path (e.g.,
          as "mne-python/examples/MNE-kiloword-data"), the data
          will be automatically downloaded to the specified folder.
      force_update : bool
          Force update of the dataset even if a local copy exists.
      update_path : bool | None
          If True, set the MNE_DATASETS_KILOWORD_PATH in mne-python
          config to the given path. If None, the user is prompted.
      download : bool
          If False and the kiloword dataset has not been downloaded yet,
          it will not be downloaded and the path will be returned as
          '' (empty string). This is mostly used for debugging purposes
          and can be safely ignored by most users.

      Returns
      -------
      path : list of Path
          Local path to the given data file. This path is contained inside a list
          of length one, for compatibility.
