+;; Dummy major-mode for testing `faceup', a regression test system for
+;; font-lock keywords (syntax highlighting rules for Emacs).
+;;
+;; This mode use `syntax-propertize' to set the `syntax-table'
+;; property on "<" and ">" in "<TEXT>" to make them act like
+;; parentheses.
+;;
+;; This mode also sets the `help-echo' property on the text WARNING,
+;; the effect is that Emacs displays a tooltip when you move your
+;; mouse on to the text.
