599 ;; Both FIRST and SECOND have the same level of nesting: the cadr of a
600 ;; bookmark record is a list of entry information. FIRST and SECOND
601 ;; differ in the form of the record information: FIRST uses a list of
602 ;; atoms, and SECOND uses an alist. In the FIRST format, the order of
603 ;; the list elements matters. In the SECOND format, the order of the
604 ;; alist elements is unimportant. The SECOND format facilitates the
605 ;; addition of new kinds of elements, to support new kinds of
606 ;; bookmarks or code evolution.
608 ;; The CURRENT format removes a level of nesting wrt FIRST and SECOND,
609 ;; saving one cons cell per bookmark: the cadr of a bookmark record is
610 ;; no longer a cons. Why that change was made remains a mystery --
611 ;; just be aware of it. (Be aware too that this explanatory comment

614 ;; To deal with the change from FIRST format to SECOND, conversion
