11 | ;;; Summary: |
12 | ;; This package is for setting "bookmarks" in files. A bookmark | |
13 | ;; associates a string with a location in a certain file. Thus, you | |
14 | ;; can navigate your way to that location by providing the string. | |

34 | ;; Thanks to David Bremner <bremner@cs.sfu.ca> for thinking of and | |
35 | ;; then implementing the bookmark-current-bookmark idea. He even | |

38 | ;; Thanks to Gregory M. Saunders <saunders@cis.ohio-state.edu> for | |

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 | |
d23e2c3f KF |
43 | ;; and the menu-bar). |
44 | ||
d22d6453 RS |
45 | ;; And much thanks to David Hughes <djh@harston.cv.com> for many small |
46 | ;; suggestions and the code to implement them (like | |
e3437989 | 47 | ;; bookmark-bmenu-check-position, and some of the Lucid compatibility |
d22d6453 RS |
48 | ;; stuff). |
49 | ||
e3437989 | 50 | ;; Kudos (whatever they are) go to Jim Blandy <jimb@cyclic.com> |
d23e2c3f KF |
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. | |

58 | ;; Jonathan Stigelman <stig@key.amdahl.com> gave patches for default |

61 | ;; end of each year :-) (No, seriously, thanks Jonathan!) | |
