| 27 | ;;; Commentary: |
| 28 | |
| 29 | ;; This package is for setting "bookmarks" in files. A bookmark |
| 30 | ;; associates a string with a location in a certain file. Thus, you |
| 31 | ;; can navigate your way to that location by providing the string. |
| 32 | ;; See the "User Variables" section for customizations. |
| 33 | |
| 34 | ;; Thanks to David Bremner <bremner@cs.sfu.ca> for thinking of and |
| 35 | ;; then implementing the bookmark-current-bookmark idea. He even |
| 36 | ;; sent *patches*, bless his soul... |
| 37 | |
| 38 | ;; Thanks to Gregory M. Saunders <saunders@cis.ohio-state.edu> for |
| 39 | ;; fixing and improving bookmark-time-to-save-p. |
| 40 | |
| 41 | ;; Thanks go to Andrew V. Klein <avk@cig.mot.com> for the code that |
| 42 | ;; sorts the alist before presenting it to the user (in bookmark-bmenu-list |
| 43 | ;; and the menu-bar). |
| 44 | |
| 45 | ;; And much thanks to David Hughes <djh@harston.cv.com> for many small |
| 46 | ;; suggestions and the code to implement them (like |
| 47 | ;; bookmark-bmenu-check-position, and some of the Lucid compatibility |
| 48 | ;; stuff). |
| 49 | |
| 50 | ;; Kudos (whatever they are) go to Jim Blandy <jimb@red-bean.com> |
| 51 | ;; for his eminently sensible suggestion to separate bookmark-jump |
| 52 | ;; into bookmark-jump and bookmark-jump-noselect, which made many |
| 53 | ;; other things cleaner as well. |
| 54 | |
| 55 | ;; Thanks to Roland McGrath for encouragement and help with defining |
| 56 | ;; autoloads on the menu-bar. |
| 57 | |
| 58 | ;; Jonathan Stigelman <stig@hackvan.com> gave patches for default |
| 59 | ;; values in bookmark-jump and bookmark-set. Everybody please keep |
| 60 | ;; all the keystrokes they save thereby and send them to him at the |
| 61 | ;; end of each year :-) (No, seriously, thanks Jonathan!) |
| 62 | |
| 63 | ;; Buckets of gratitude to John Grabowski <johng@media.mit.edu> for |
| 64 | ;; thinking up the annotations feature and implementing it so well. |
| 65 | |
| 66 | ;; Based on info-bookmark.el, by Karl Fogel and Ken Olstad |
| 67 | ;; <olstad@msc.edu>. |
| 68 | |
| 69 | ;; Thanks to Mikio Nakajima <PBC01764@niftyserve.or.jp> for many bugs |
| 70 | ;; reported and fixed. |
| 71 | |
| 72 | ;; Thank you, Michael Kifer, for contributing the XEmacs support. |
| 73 | |
| 74 | ;; Enough with the credits already, get on to the good stuff: |

| 85 | ;; |
| 86 | ;; If variable bookmark-use-annotations is non-nil, an annotation is |
| 87 | ;; queried for when setting a bookmark. |
| 88 | ;; |
| 89 | ;; The bookmark list is sorted lexically by default, but you can turn |
| 90 | ;; this off by setting bookmark-sort-flag to nil. If it is nil, then |
| 91 | ;; the list will be presented in the order it is recorded |
| 92 | ;; (chronologically), which is actually fairly useful as well. |
