% - kleinere Korrekturen, Martin Wunderli, 25.4.1991, 20.7.1991
% - an schweizer Sichtumschlge und eigene Bed
frnisse angepat, Martin
%   Wunderli, 29. Mrz 1991. Es wird die Benutzung des DINA4-Style
%   vorausgesetzt.
% - die Namensangaben gegen meine eigenen ausgetauscht, Stefan Lindner 16-Jun-89
% - modifiziert fuer eigene Beduerfnisse, Lutz Birkhahn 06-Apr-89
%   Ideen kommen von H. Kopka (LaTeX -- Eine Einfuehrung), vielen durch-
%   gesehenen Briefen und von meinem Kopf...
%   HINWEIS: Dieser Style war urspruenglich nur fuer meinen privaten
%   Gebrauch bestimmt, deshalb ist die Dokumentation und Kommentierung
%   auch recht spaerlich. Es war mal geplant, eine Style-Option "private"
%   zu unterstuetzen, bisher wird jedoch nur ein \if-Makro definiert
%   (\if@private), aber nirgends abgefragt... Wer das Buch von Kopka hat,
%   kann dort eine wesentlich ausf
hrlichere Beschreibung lesen.
