;;; Commentary:
;; This file implements links to BBDB database entries from within Org-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.
;; It also implements an interface (based on Ivar Rummelhoff's
;; bbdb-anniv.el) for those org-mode users, who do not use the diary
;; but who do want to include the anniversaries stored in the BBDB
;; into the org-agenda. If you already include the `diary' into the
;; agenda, you might want to prefer to include the anniversaries in
;; the diary using bbdb-anniv.el.
;;
;; Put the following in /somewhere/at/home/diary.org and make sure
;; that this file is in `org-agenda-files'.
;;
;; %%(org-bbdb-anniversaries)
;;
;; For example my diary.org looks like:
;; * Anniversaries
;; #+CATEGORY: Anniv
;; %%(org-bbdb-anniversaries)
;;
;;
;; To add an anniversary to a BBDB record, press `C-o' in the record.
;; You will be prompted for the field name, in this case it must be
;; "anniversary". If this is the first time you are using this field,
;; you need to confirm that it should be created.
;;
;; The format of an anniversary field stored in BBDB is the following
;; (items in {} are optional):
;;
;; YYYY-MM-DD{ CLASS-OR-FORMAT-STRING}
;; {\nYYYY-MM-DD CLASS-OR-FORMAT-STRING}...
;;
;; CLASS-OR-FORMAT-STRING is one of two things:
;;
;; - an identifier for a class of anniversaries (eg. birthday or
;; wedding) from `org-bbdb-anniversary-format-alist' which then
;; defines the format string for this class
;; - the (format) string displayed in the diary.
;;
;; You can enter multiple anniversaries for a single BBDB record by
;; separating them with a newline character. At the BBDB prompt for
;; the field value, type `C-q C-j' to enter a newline between two
;; anniversaries.
;;
;; If you omit the CLASS-OR-FORMAT-STRING entirely, it defaults to the
;; value of `org-bbdb-default-anniversary-format' ("birthday" by
;; default).
;;
;; The substitutions in the format string are (in order):
;; - the name of the record containing this anniversary
;; - the number of years
;; - an ordinal suffix (st, nd, rd, th) for the year
;;
;; See the documentation of `org-bbdb-anniversary-format-alist' for
;; further options.
;;
;; Example
;;
;; 1973-06-22
;; 20??-??-?? wedding
;; 1998-03-12 %s created bbdb-anniv.el %d years ago
;;
;; From Org's agenda, you can use `C-c C-o' to jump to the BBDB
;; link from which the entry at point originates.
