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

39 ;; Thanks to Gregory M. Saunders <saunders@cis.ohio-state.edu> for
40 ;; fixing and improving bookmark-time-to-save-p.
42 ;; Thanks go to Andrew V. Klein <avk@cig.mot.com> for the code that
43 ;; sorts the alist before presenting it to the user (in bookmark-bmenu-list
46 ;; And much thanks to David Hughes <djh@harston.cv.com> for many small
47 ;; suggestions and the code to implement them (like
48 ;; bookmark-bmenu-check-position, and some of the Lucid compatibility
51 ;; Kudos (whatever they are) go to Jim Blandy <jimb@red-bean.com>
52 ;; for his eminently sensible suggestion to separate bookmark-jump
53 ;; into bookmark-jump and bookmark-jump-noselect, which made many
54 ;; other things cleaner as well.
56 ;; Thanks to Roland McGrath for encouragement and help with defining
57 ;; autoloads on the menu-bar.
59 ;; Jonathan Stigelman <stig@hackvan.com> gave patches for default
60 ;; values in bookmark-jump and bookmark-set. Everybody please keep
61 ;; all the keystrokes they save thereby and send them to him at the
62 ;; end of each year :-) (No, seriously, thanks Jonathan!)
64 ;; Buckets of gratitude to John Grabowski <johng@media.mit.edu> for
65 ;; thinking up the annotations feature and implementing it so well.
67 ;; Based on info-bookmark.el, by Karl Fogel and Ken Olstad
70 ;; Thanks to Mikio Nakajima <PBC01764@niftyserve.or.jp> for many bugs

73 ;; Thank you, Michael Kifer, for contributing the XEmacs support.
