+;;; Commentary:
+
+;; Refinery is a refined, minimalist theme inspired by the beautiful
+;; Commentary theme by Simon Zelazny.  Like Commentary, Refinery uses
+;; a concept of ``layers'' of style to visually accentuate the more
+;; important parts text in a useful yet subtle way, while keeping the
+;; distractions at a minimum.
+
+;; 1. Comments are in red, so they easily stand out!
+;;
+;; 2. Strings have a subtle light yellow background, so as to help
+;; make it easier to spot their beginning and end points.
+;;
+;; 3. Function/macro definitions are in bold to help them stand out
+;; from ordinary text.
