  25 ;; Change Log:
  26
  27 ;; moved posting and mail code from rnews.el
  28 ;;      tower@prep.ai.mit.edu Wed Oct 29 1986
  29 ;; brought posting code almost up to the revision of RFC 850 for News 2.11
  30 ;; - couldn't see handling the special meaning of the Keyword: poster
  31 ;; - not worth the code space to support the old A news Title: (which
  32 ;;   Subject: replaced) and Article-I.D.: (which Message-ID: replaced)
  33 ;;      tower@prep Nov 86
  34 ;; changed C-c C-r key-binding due to rename of news-caesar-buffer-body
  35 ;;      tower@prep 21 Nov 86
  36 ;; added (require 'rnews)       tower@prep 22 Apr 87
  37 ;; restricted call of news-show-all-headers in news-post-news & news-reply
  38 ;;      tower@prep 28 Apr 87
  39 ;; commented out Posting-Front-End to save USENET bytes tower@prep Jul 31 87
  40 ;; commented out -n and -t args in news-inews     tower@prep 15 Oct 87
