    # When the given key starts with a period, it will be scoped by the current
    # controller and action. So if you call <tt>translate(".foo")</tt> from
    # <tt>PeopleController#index</tt>, it will convert the call to
    # <tt>I18n.translate("people.index.foo")</tt>. This makes it less repetitive
    # to translate many keys within the same controller / action and gives you a
    # simple framework for scoping them consistently.
