+     "Turbo aims to be as fast as single-page web application without having
+to write any JavaScript.  Turbo accelerates links and form submissions without
+requiring server-side changes to the generated HTML.  It allows carving up a
+page into independent frames, which can be lazy-loaded and operated as
+independent components.  Finally, it helps making partial page updates using
+just HTML and a set of CRUD-like container tags.  These three techniques
+reduce the amount of custom JavaScript that many web applications need to
+write by an order of magnitude.  And for the few dynamic bits that are left,
+Stimulus can be used.")
