;;; 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'.

;;; Code:

(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-add-link-type "bbdb" 'org-bbdb-open 'org-bbdb-export)

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

(defun org-bbdb-export (path desc format)
  "Create the export version of a BBDB link specified by PATH or DESC.
