+# Memoize module simply memoizes the values returned by lookup using
+# a flat hash and can tremendously speed up the lookup process in a backend.
+#
+# To enable it you can simply include the Memoize module to your backend:
+#
+#   I18n::Backend::Simple.include(I18n::Backend::Memoize)
+#
+# Notice that it's the responsibility of the backend to define whenever the
+# cache should be cleaned.
