;;; Commentary:
;; nnnil is a Gnus backend that provides no groups or articles. It's useful
;; as a primary select method when you want all your real select methods to
;; be secondary or foreign.
;;; Code:
(eval-and-compile
(require 'nnheader))
(defvar nnnil-status-string "")
(defun nnnil-retrieve-headers (articles &optional group server fetch-old)
(with-current-buffer nntp-server-buffer
(erase-buffer))
