  29 ;; This file implements links to BBDB database entries from within Org-mode.
  30 ;; Org-mode loads this module by default - if this is not what you want,
  31 ;; configure the variable `org-modules'.
  32
  33 ;; It also implements an interface (based on Ivar Rummelhoff's
  34 ;; bbdb-anniv.el) for those org-mode users, who do not use the diary
  35 ;; but who do want to include the anniversaries stored in the BBDB
  36 ;; into the org-agenda.  If you already include the `diary' into the
  37 ;; agenda, you might want to prefer to include the anniversaries in
  38 ;; the diary using bbdb-anniv.el.
  39 ;;
  40 ;; Put the following in /somewhere/at/home/diary.org and make sure
  41 ;; that this file is in `org-agenda-files`
  42 ;;
  43 ;; %%(org-bbdb-anniversaries)
  44 ;;
  45 ;; For example my diary.org looks like:
  46 ;; * Anniversaries
  47 ;; #+CATEGORY: Anniv
  48 ;; %%(org-bbdb-anniversaries)
  49 ;;
  50 ;;
  51 ;; The anniversaries are stored in BBDB in the field `anniversary'
  52 ;; in the format
  53 ;;
  54 ;;     YYYY-MM-DD{ CLASS-OR-FORMAT-STRING}*
  55 ;;     {\nYYYY-MM-DD CLASS-OR-FORMAT-STRING}*
  56 ;;
  57 ;; CLASS-OR-FORMAT-STRING is one of two things:
  58 ;;
  59 ;;  * an identifier for a class of anniversaries (eg. birthday or
  60 ;;    wedding) from `org-bbdb-anniversary-format-alist'.
  61 ;;  * the (format) string displayed in the diary.
  62 ;;
  63 ;; It defaults to the value of `org-bbdb-default-anniversary-format'
  64 ;; ("birthday" by default).
  65 ;;
  66 ;; The substitutions in the format string are (in order):
  67 ;;  * the name of the record containing this anniversary
  68 ;;  * the number of years
  69 ;;  * an ordinal suffix (st, nd, rd, th) for the year
  70 ;;
  71 ;; See the documentation of `org-bbdb-anniversary-format-alist' for
  72 ;; further options.
  73 ;;
  74 ;; Example
  75 ;;
  76 ;;       1973-06-22
  77 ;;       20??-??-?? wedding
  78 ;;       1998-03-12 %s created bbdb-anniv.el %d years ago
  79 ;;
  80 ;; From Org's agenda, you can use `C-c C-o' to jump to the BBDB
  81 ;; link from which the entry at point originates.
