;;; Commentary:
-;; Highlights code by scope. Top-level scopes are one color, second-level
-;; scopes are another color, and so on. Variables retain the color of the
scope
-;; in which they are defined. A variable defined in an outer scope referenced
-;; by an inner scope is colored the same as the outer scope.
-
-;; By default, comments and strings are still highlighted syntactically.
+;; Add Emacs Lisp context coloring support.
