732 ;; Each Custom theme is defined by a symbol, called the theme name.
733 ;; The `theme-settings' property of the theme name records the
734 ;; variable and face settings of the theme. This property is a list
739 ;; - PROP is either `theme-value' or `theme-face'
741 ;; - THEME is the theme name (redundant, but simplifies the code)
742 ;; - VALUE is an expression that gives the theme's setting for SYMBOL.
744 ;; The theme name also has a `theme-feature' property, whose value is
745 ;; specified when the theme is defined (see `custom-declare-theme').
746 ;; Usually, this is just a symbol named THEME-theme. This lets
747 ;; external libraries call (require 'foo-theme).
750 ;; an *enabled* theme has a `theme-value' or `theme-face' property,
755 ;; which have the same meanings as in `theme-settings'.

758 ;; theme precedence. Thus, the first element is always the one that
