29 ;; The following code is used to define the customization properties

30 ;; for builtin variables, and variables in the packages that are

31 ;; preloaded /very/ early, before custom.el itself (replace.el is such

32 ;; an example). The way it handles custom stuff is dirty, and should

33 ;; be regarded as a last resort. DO NOT add variables here, unless

34 ;; you know what you are doing.
