;; Elements of this list have the form:
;; SYMBOL GROUP TYPE VERSION REST...
;; SYMBOL is the name of the variable.
;; GROUP is the custom group to which it belongs (may also be a list
;; of groups)
;; TYPE is the defcustom :type.
;; VERSION is the defcustom :version (or nil).
;; REST is a set of :KEYWORD VALUE pairs.  Accepted :KEYWORDs are:
;; :standard - standard value for SYMBOL (else use current value)
;; :set - custom-set property
;; :risky - risky-local-variable property
;; :safe - safe-local-variable property
;; :tag - custom-tag property
