Action View

Action View is a framework for handling view template lookup and rendering,
and provides view helpers that assist when building HTML forms, Atom feeds
and more.  Template formats that Action View handles are ERB (embedded Ruby,
typically used to inline short Ruby snippets inside HTML), and XML Builder.

This is for Ruby on Rails 7.0.
