-defmodule Irc.Plugin.TempRef do
-  @moduledoc """
-  This module allows to easily implement local temporary simple references for easy access from IRC.
-
-  For example, your plugin output could be acted on, and instead of giving the burden for the user to
-  write or copy that uuid, you could give them a small alphanumeric reference to use instead.
-
-  You can configure how many and for how long the references are kept.
-
-  ## Usage
-
-  `import Irc.Plugin.TempRef`
-
-  ```elixir
-  defmodule Irc.MyPlugin do
-    defstruct [:temprefs]
-
-    def init(_) do
-      # …
-      {:ok, %__MODULE__{temprefs: new_temp_refs()}
-    end
-  end
-  ```
