+    # If you pass :manage it will apply to every action. Other common actions here are
+    # :read, :create, :update and :destroy.
+    #
+    # The second argument is the resource the user can perform the action on. If you pass
+    # :all it will apply to every resource. Otherwise pass a Ruby class of the resource.
+    #
+    # The third argument is an optional hash of conditions to further filter the objects.
+    # For example, here the user can only update published articles.
+    #
+    #   can :update, Article, :published => true
