+;;; Custom Themes
+
+;; Custom themes are collections of settings that can be enabled or
+;; disabled as a unit.
+
+;; Each Custom theme is defined by a symbol, called the theme name.
+;; The `theme-settings' property of the theme name records the
+;; variable and face settings of the theme. This property is a list
+;; of elements, each of the form
+;;
+;; (PROP SYMBOL THEME VALUE)
+;;
+;; - PROP is either `theme-value' or `theme-face'
+;; - SYMBOL is the face or variable name
+;; - THEME is the theme name (redundant, but simplifies the code)
+;; - VALUE is an expression that gives the theme's setting for SYMBOL.
+;;
+;; The theme name also has a `theme-feature' property, whose value is
+;; specified when the theme is defined (see `custom-declare-theme').
+;; Usually, this is just a symbol named THEME-theme. This lets
+;; external libraries call (require 'foo-theme).
+
+;; In addition, each symbol (either a variable or a face) affected by
+;; an *enabled* theme has a `theme-value' or `theme-face' property,
+;; which is a list of elements each of the form
+;;
+;; (THEME VALUE)
+;;
+;; which have the same meanings as in `theme-settings'.
+;;
+;; The `theme-value' and `theme-face' lists are ordered by decreasing
+;; theme precedence. Thus, the first element is always the one that
+;; is in effect.
+
+;; Each theme is stored in a theme file, with filename THEME-theme.el.
+;; Loading a theme basically involves calling (load "THEME-theme")
+;; This is done by the function `load-theme'. Loading a theme
+;; automatically enables it.
+;;
+;; When a theme is enabled, the `theme-value' and `theme-face'
+;; properties for the affected symbols are set. When a theme is
+;; disabled, its settings are removed from the `theme-value' and
+;; `theme-face' properties, but the theme's own `theme-settings'
