;;; Commentary:
;; This file adds support for `scrlttr2.cls'.
;; Since I just recently switched from `g-brief.cls' to the
;; KOMA-Script letter class *and* I don't really write many
;; snailmails, there are probably some superflous macros included and
;; important ones left out. Comments appreciated.
;; I left out any length and positioning macros since those should be
;; set in a personal `*.lco'-File. IMHO.
