-- Retrieves the names of all trigger resources in this Amazon Web Services
-- account, or the resources with the specified tag. This operation allows
-- you to see which resources are available in your account, and their
-- names.
--
-- This operation takes the optional @Tags@ field, which you can use as a
-- filter on the response so that tagged resources can be retrieved as a
-- group. If you choose to use tags filtering, only resources with the tag
-- are retrieved.
