defmodule Antikythera.Gettext do
  @moduledoc """
  A thin wrapper around `Gettext.__using__/1` to forward error logs to each gear's logger.

  Usage of this module is exactly the same as `Gettext`; just `use #{inspect(__MODULE__)}` instead of `use Gettext`.
  Options given to `#{inspect(__MODULE__)}.__using__/1` are directly passed to `Gettext.__using__/1`.
  This module overrides the default implementation of `c:Gettext.Backend.handle_missing_bindings/2`
  to suit the use cases for antikythera gears.
