+# I18n Pluralization are useful when you want your application to
+# customize pluralization rules.
+#
+# To enable locale specific pluralizations you can simply include the
+# Pluralization module to the Simple backend - or whatever other backend you
+# are using.
+#
+#   I18n::Backend::Simple.include(I18n::Backend::Pluralization)
+#
+# You also need to make sure to provide pluralization algorithms to the
+# backend, i.e. include them to your I18n.load_path accordingly.

+      # Overwrites the Base backend translate method so that it will check the
+      # translation meta data space (:i18n) for a locale specific pluralization
+      # rule and use it to pluralize the given entry. I.e. the library expects
+      # pluralization rules to be stored at I18n.t(:'i18n.plural.rule')
+      #
+      # Pluralization rules are expected to respond to #call(count) and
+      # return a pluralization key. Valid keys depend on the translation data
+      # hash (entry) but it is generally recommended to follow CLDR's style,
+      # i.e., return one of the keys :zero, :one, :few, :many, :other.
+      #
+      # The :zero key is always picked directly when count equals 0 AND the
+      # translation data has the key :zero. This way translators are free to
+      # either pick a special :zero translation even for languages where the
+      # pluralizer does not return a :zero key.
