;;; Commentary:

;; This file implements links to BBDB database entries for Org-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.

(require 'org)

;; Declare external functions and variables
(declare-function bbdb "ext:bbdb-com" (string elidep))
(declare-function bbdb-company "ext:bbdb-com" (string elidep))
(declare-function bbdb-current-record "ext:bbdb-com" 
		  (&optional planning-on-modifying))
(declare-function bbdb-name "ext:bbdb-com" (string elidep))
(declare-function bbdb-record-getprop "ext:bbdb" (record property))
(declare-function bbdb-record-name "ext:bbdb" (record))

;; Install the link type

      (org-store-link-props :type "bbdb" :name name :company company
			    :link link :description name)
