;;; Commentary:
;; This file implements links to Gnus groups and messages 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)
(eval-when-compile
(require 'gnus-sum))
;; Customization variables
(defcustom org-usenet-links-prefer-google nil
"Non-nil means, `org-store-link' will create web links to Google groups.
When nil, Gnus will be used for such links.
Using a prefix arg to the command \\[org-store-link] (`org-store-link')
negates this setting for the duration of the command."
