  26 ;;; Commentary:
  27
  28 ;; This file implements links to BBDB database entries from within Org.
  29 ;; Org mode loads this module by default - if this is not what you want,
  30 ;; configure the variable `org-modules'.
  31
  32 ;; It also implements an interface (based on Ivar Rummelhoff's
  33 ;; bbdb-anniv.el) for those Org users, who do not use the diary
  34 ;; but who do want to include the anniversaries stored in the BBDB
  35 ;; into the org-agenda.  If you already include the `diary' into the
  36 ;; agenda, you might want to prefer to include the anniversaries in
  37 ;; the diary using bbdb-anniv.el.
  38 ;;
  39 ;; Put the following in /somewhere/at/home/diary.org and make sure
  40 ;; that this file is in `org-agenda-files'.
  41 ;;
  42 ;; %%(org-bbdb-anniversaries)
  43 ;;
  44 ;; For example my diary.org looks like:
  45 ;; * Anniversaries
  46 ;; #+CATEGORY: Anniv
  47 ;; %%(org-bbdb-anniversaries)
  48 ;;
  49 ;;
  50 ;; To add an anniversary to a BBDB record, press `C-o' in the record.
  51 ;; You will be prompted for the field name, in this case it must be
  52 ;; "anniversary".  If this is the first time you are using this field,
  53 ;; you need to confirm that it should be created.
  54 ;;
  55 ;; The format of an anniversary field stored in BBDB is the following
  56 ;; (items in {} are optional):
  57 ;;
  58 ;;     YYYY-MM-DD{ CLASS-OR-FORMAT-STRING}
  59 ;;     {\nYYYY-MM-DD CLASS-OR-FORMAT-STRING}...
  60 ;;
  61 ;; CLASS-OR-FORMAT-STRING is one of two things:
  62 ;;
  63 ;;  - an identifier for a class of anniversaries (eg. birthday or
  64 ;;    wedding) from `org-bbdb-anniversary-format-alist' which then
  65 ;;    defines the format string for this class
  66 ;;  - the (format) string displayed in the diary.
  67 ;;
  68 ;; You can enter multiple anniversaries for a single BBDB record by
  69 ;; separating them with a newline character.  At the BBDB prompt for
  70 ;; the field value, type `C-q C-j' to enter a newline between two
  71 ;; anniversaries.
  72 ;;
  73 ;; If you omit the CLASS-OR-FORMAT-STRING entirely, it defaults to the
  74 ;; value of `org-bbdb-default-anniversary-format' ("birthday" by
  75 ;; default).
  76 ;;
  77 ;; The substitutions in the format string are (in order):
  78 ;;  - the name of the record containing this anniversary
  79 ;;  - the number of years
  80 ;;  - an ordinal suffix (st, nd, rd, th) for the year
  81 ;;
  82 ;; See the documentation of `org-bbdb-anniversary-format-alist' for
  83 ;; further options.
  84 ;;
  85 ;; Example
  86 ;;
  87 ;;       1973-06-22
  88 ;;       20??-??-?? wedding
  89 ;;       1998-03-12 %s created bbdb-anniv.el %d years ago
  90 ;;
  91 ;; From Org's agenda, you can use `C-c C-o' to jump to the BBDB
  92 ;; link from which the entry at point originates.
