def initialize
  # @options_config stores a config that is specified in the command line.
  # This takes precedence over configs located in any directories
  @options_config = nil

  # @path_cache maps directories to configuration paths. We search
  # for .rubocop.yml only if we haven't already found it for the
  # given directory.
  @path_cache = {}

  # @object_cache maps configuration file paths to
  # configuration objects so we only need to load them once.
