;; Thanks to David Bremner <bremner@cs.sfu.ca> for thinking of and

;; sent *patches*, bless his soul...

;; Thanks to Gregory M. Saunders <saunders@cis.ohio-state.edu> for
;; fixing and improving bookmark-time-to-save-p.

;; Thanks go to Andrew V. Klein <avk@rtsg.mot.com> for the code that
;; sorts the alist before presenting it to the user (in list-bookmarks
;; and the menu-bar).

;; And much thanks to David Hughes <djh@harston.cv.com> for many small
;; suggestions and the code to implement them (like
;; Bookmark-menu-check-position, and some of the Lucid compatibility
;; stuff).

;; Kudos (whatever they are) go to Jim Blandy <jimb@cs.oberlin.edu>
;; for his eminently sensible suggestion to separate bookmark-jump
;; into bookmark-jump and bookmark-jump-noselect, which made many
;; other things cleaner as well.

;; Thanks to Roland McGrath for encouragement and help with defining
;; autoloads on the menu-bar.

;; Jonathan Stigelman <stig@key.amdahl.com> gave patches for default
;; values in bookmark-jump and bookmark-set.  Everybody please keep
;; all the keystrokes they save thereby and send them to him at the
;; end of each year :-)  (No, seriously, thanks Jonathan!)

;; Choice (both in Chicago's Chinatown).  Well, both.  How about you?

;;; Commentary on code:

;; bookmark alist format:
;;               (...
;;                (bookmark-name (filename
;;                                string-in-front
;;                                string-behind
;;                                point))
;;                ...)
;;
;; bookmark-name is the string the user gives the bookmark and
;; accesses it by from then on.  filename is the location of the file
;; in which the bookmark is set.  string-in-front is a string of
;; `bookmark-search-size' chars of context in front of the point the
;; bookmark is set at, string-behind is the same thing after the
;; point.  bookmark-jump will search for string-behind and
;; string-in-front in case the file has changed since the bookmark was
;; set.  It will attempt to place the user before the changes, if
;; there were any.
;;
;; The bookmark list is sorted lexically by default, but you can turn
;; this off by setting bookmark-sort-flag to nil.  If it is nil, then
;; the list will be presented in the order it is recorded
;; (chronologically), which is actually fairly useful as well.
