+Changes (``diff mpdinbrief.dtx dinbrief.dtx''):
+
+  - external horizontal ``pressure'' onto backaddress reduced from ``hfill'' to ``hfil''
+    % makes it possible to use ``\hfill'' between the fields of backaddress to 
+    % widen it to the maximum possible extent
+
+  - answertonew line changed: 
+      + date/place go to the right border
+      + every horizontal item takes just the space it needs 
+        and white space is shared equally
+    % may be this is not conforming to DIN 676, but the given placement of items
+    % was not satisfying:  why should an empty field eat up so much space ? 
+
+  - fontseries for the concern (Betreff) line: ``bx''
+    % isn't it a kind of heading for the whole thing ?
+
+  - defaultfont for \signature: \footnotesize
+    % because I think it's overweighted with \normalsize
+    % you only want to be able to decypher some cryptic signature
+
+  - cc, ps, encl: 
+      + fontseries ``bx''
+      + strings (PS, Anlage(n), Verteiler) now ending with ``:''
+      + vspace(.3ex) after these strings
+    % because these strings bear structuring significance in a document
+
+  - ps, cc, encl following the closing pushed down to the bottom of the page
+    % I consider them being a kind of final contents of a complete letter package;
+    % putting them to close to the closing binds them to tightly to the central text.
+
+  - new example
+
+  - certainly some new bugs brought in  % don't call them features !
+
+
+
+May be, it would have been a good idea to merge all these changes into dinbrief
+by introducing switches to make them optional: 
+  - This would blow up the code size of dinbrief.  
+  - It's a matter of taste: 
+      + Your taste  % if you like it [or not], have an influence onto the maintainers
+      + the taste of the maintainers of dinbrief
+.  
+Should there be more than some spread out fools, who like and use my modifications, 
+then it'll be certainly a good idea to merge them into the original distribution.  
+But we'll only know, if somebody tells us: so send us a mail with your opinion!

+%   This document serves as User's Guide and as documentation of the new
+%   \LaTeX-Style or a \LaTeXe-Class.  This class/style implements
+%   a new document layout for writing letters, according to the rules
+%   of DIN (Deutsches Institut f\"ur Normung, German standardization
+%   institute). The User's Guide is written in German, since we assume
+%   the style is of minor interest outside Germany.  Of course, most of
+%   the macros are explained in English.

+
+Mit \LaTeX\ k"onnen (nat"urlich) auch Briefe geschrieben werden.
+F"ur englische Briefe gibt es die Dokumentklasse \envname{letter}.
+Deutsche Briefe k"onnen mit der Klasse \envname{mpdinbrief}
+geschrieben werden.
+
+Die vorliegende Klasse \envname{mpdinbrief} basiert auf dem
+\envname{dinbrief}-Stil der Universit"at Karlsruhe. Dieser
+Stil wurde aus \envname{dletter.sty} entwickelt, welcher
+von D.~Heinrich abgefa"st wurde. Seinerseits geht dieser
+zur"uck auf den Stil \envname{a4letter} von H.~Partl, welcher
+seinen Ursprung im urspr"unglichen \envname{letter}-Stil
+von L.~Lamport hatte. Zus"atzlich wurden aus den \envname{dinbrief.sty}
+von R.~Sengerling der Befehlsvorrat und die Option \verb|norm|
+"ubernommen. Ferner enth"alt diese Klasse Tips und Anregungen von
+B.~Raichle.
+
+In den Briefen k"onnen u.a.\ Formeln,
+Tabellen und beliebige Listen verwendet werden.
+In einem Dokument k"onnen mehrere Briefe geschrieben werden.
+Die Gliederung in Abs"atze erfolgt durch Einf"ugen einer
+Leerzeile (wie in \LaTeX\ "ublich).
+
+\sect{Befehle in der {\protect\tt mpdinbrief}-Klasse}
+\index{Briefe!DIN 676}\index{DIN-Brief}\index{Briefe!mpdinbrief@\envname{dinbrief}}
+
+Bereits vor \env\begin{document} kann man Angaben machen, die f"ur
+alle Briefe g"ultig sind, z.B.\ {\bf Absender\/} (\cs{address}
+bzw.\ \cs{backaddress}), {\bf Absendeort\/} (\cs{place}),
+{\bf Telefon\/} (\cs{phone}) und {\bf Unterschrift\/} (\cs{signature}).
+
+\ssect{Aus der {\protect\tt letter}-Klasse "ubernommene Befehle}
+
+Jeder Brief steht in einer eigenen \envname{letter}-Umgebung.
+Der Empf"anger wird als Argument des
+\env\begin{letter}-Befehls angegeben
+(\env\begin{letter}\arg{Anschrift}).
+
+Eine entscheidende Bedeutung beim Schreiben von Briefen
+hat der \cs{opening}-Befehl. Nur dieser Befehl setzt
+den Briefkopf, die Absenderangaben und die Adresse des
+Empf"angers. Die {\bf Anrede des Empf"angers\/} wird als
+Argument angegeben (\cmd\opening\arg{Anrede}).
+
+Danach folgt der eigentliche Brieftext. Die abschlie"sende
+{\bf Gru"sformel\/} wird mit dem Befehl \cmd\closing\arg{Gru"sformel}
+gesetzt. Dieser Befehl f"ugt auch die maschinenschriftliche
+Wiederholung der Unterschrift an, wie sie mit dem
+\cs{signature}-Befehl festgelegt wurde.
+
+Im Anschlu"s an die Gru"sformel werden {\bf Anlagen-\/}
+(\cmd\encl\arg{Anlage}), {\bf Verteilvermerke\/}
+(\cmd\cc\arg{Verteiler}) und das {\bf Postscriptum\/}
+(\cmd\ps\arg{Postscriptum}) an den Brief angef"ugt.
+
+Mit dem Befehl \cs{makelabels} (vor \env\begin{document})
+werden zus"atzlich {\bf Adre"s-Etiketten\/} erzeugt.
+
+Dar"uberhinaus wurden die oben erw"ahnten Befehle
+\cs{address}, \cs{place} und \cs{signature} aus
+der \envname{letter}-Klasse "ubernommen.

+\ssect{Zus"atzliche Befehle im DIN-Brief}
+
+Der Befehl \cmd\phone\arg{Vorwahl}\arg{Rufnummer/Durchwahl}
+legt die {\bf Telefonnummer\/} des Absenders fest.
+Sie wird in der Bezugszeichenzeile ausgegeben.
+
+Der {\bf Bezug\/} auf einen empfangenen Brief ist m"oglich
+mit Hilfe des Befehls
+\cmd\yourmail\arg{Ihre Zeichen, Ihre Nachricht vom}.
+
+Mit dem Befehl \cmd\sign\arg{Unsere Zeichen, unsere Nachricht vom}
+kann eine {\bf eigene Kennzeichnung\/} des Briefes angegeben werden.
+
+Mit dem Befehl \cmd\writer\arg{Sachbearbeiter} kann
+der {\bf Name des Sachbearbeiters\/} festgelegt werden.
+
+Die Bezugszeichenzeile wird nur gesetzt, falls einer der
+Befehle \cs{yourmail}, \cs{sign} oder \cs{writer} verwendet
+wird. Der Befehl \cs{writer} schaltet zus"atzlich auf das
+in der DIN Norm~676 (Entwurf Mai~1991) festgelegte Layout um.
+
+Der {\bf Betreff (die stichwortartige Inhaltsangabe)\/} des
+Briefes wird durch den Befehl \cs{subject}\arg{Betreff}
+angegeben. Mit \cs{backaddress} wird die Adresse festgelegt,
+die als {\bf Absenderadresse im Brief\kern0pt fenster}
+eingeblendet wird.
+
+Abbildung~\ref{brief} enth"alt ein Beispiel f"ur einen Brief.
+Die Anwendung der Befehle und ihre Reihenfolge in der Quelldatei
+kann dem Beispiel entnommen werden.
+
+F"ur alle, denen das "`Fenster"' um die Adresse nicht gef"allt,
+besteht die M"oglichkeit, durch Angabe von
+\cmd\nowindowrules\index{nowindowrules@\verb+\nowindowrules+}
+vor dem Befehl \cmd\opening\ dieses abzuschalten.
+Durch \cmd\windowrules\index{windowrules@\verb+\windowrules+} l"a"st es
+sich wieder aktivieren.
+ 
+Die Faltmarkierung am linken Papierrand wird durch den Befehl
+\cmd\nowindowtics\index{nowindowtics@\verb+\nowindowtics+} ab- und mit
+\cmd\windowtics\index{windowtics@\verb+\windowtics+} wieder angeschaltet.
+
+% \iffalse
+% Die Gr"o"se und Form von Adre"s-Etiketten kann mit den Befehlen
+% \cmd\setlabelwidth\arg{Breite}\ und \cmd\setlabelheight\arg{H"ohe}\
+% festgelegt werden. Die Anzahl der Labels in einer Spalte wird durch
+% \cmd\setlabelnumber{Anzahl} angegeben. Der obere Rand kann mit dem
+% Befehl \cmd\setlabeltopmargin{H"ohe} eingestellt werden. Mit
+% \cmd\spare{Anzahl} k"onnen am Anfang {\sl Anzahl\/} Labels frei
+% gelassen werden.
+% \fi
+Ausf"uhrungen und Erl"auterungen zum Erstellen von Adre"s-Etiketten
+finden Sie in einem eigenen Abschnitt weiter hinten in diesem Dokument.
+Die Befehlsreferenz enth"alt ebenfalls kurze Beschreibungen der
+Befehle zu den Adre"s-Etiketten.
+
+Eine einfache Absenderanschrift in der auf Schreibmaschinen "ublichen
+Form (DIN~5008) wird durch den Befehl \cmd\stdaddress\arg{Absenderanschrift}
+anstelle von \cmd\address{} erreicht. Die einzelnen Zeilen sind durch
+\verb.\\. zu trennen. Das Datum wird ebenfalls oben ausgegeben.
+Die Bezugszeichenzeile entf"allt.
+
+Mit dem Befehl \cmd\postremark\ kann ein Postvermerk gesetzt werden.
+Dieser Vermerk erscheint im Anschriftenfeld oben, von den "ubrigen
+im Argument des Befehls \env\begin{letter}\arg{Anschrift} durch eine
+Leerzeile getrennt. Der Behandlungsvermerk wird durch den
+Befehl \cmd\handling\arg{Text}\ vereinbart.
+
+Die Anlagen- und Verteilvermerke k"onnen mit dem Befehl \cmd\enclright\
+rechts auf Grad~50 anstelle nach der Gru"sformel ausgegeben werden.
+Die Befehle \cmd\encl\ und \cmd\cc\ sind dazu vor dem \cmd\closing-Befehl
+anzugeben.

+
+  \item[\cmd\writer\arg{{Sachbearbeiter}}] \hfil\break
+        Die Neufassung der Norm DIN~676 vom Mai 1991 sieht in
+        der Bezugszeichenzeile ein weiteres Feld f"ur den

+        kann ein solcher Sachbearbeiter angegeben werden.
+
+        {\sl Die Verwendung dieses Befehls gestaltet den Brief
+        entsprechend der Norm DIN~676 vom Mai 1991.\/}
+
+  \item[\cmd\subject\arg{{Betreff}}] \hfil\break
+        Mit diesem Befehl wird der Betreff gesetzt, der den
+        Empf"anger "uber den Gegenstand des Briefes
+        informiert.
+
+        \cmd\concern{} steht aus historischen Gr"unden

+
+  \item[\cmd\encl\arg{{Anlagen}}] \hfil\break
+        Der Vermerk "uber dem Brief beigef"ugte Anlagen

+        durch \cmd\\{} getrennt werden.
+
+        Die Reihenfolge der Verwendung der Befehle

+
+  \item[\cmd\cc\arg{{Verteiler}}] \hfil\break
+        Der Vermerk "uber weitere Empf"anger dieses Briefes wird

+\ssect{Einige Regeln f"ur das Briefeschreiben}
+
+Dieser Abschnitt enth"alt Passagen aus den
+Normen DIN~5008 (Regeln f"ur das Maschinenschreiben) und
+DIN~676 (Gesch"aftsbrief), erg"anzt um einige
+zus"atzliche Hinweise und Tips.
+Der Abschnitt erhebt keinen Anspruch auf
+Vollst"andigkeit. Er soll Anf"angern wie auch
+Ge"ubten einen "Uberblick "uber die wichtigsten
+Regeln geben. Ferner werden die Grenzen der
+vorliegenden Version aufgezeigt und es wird
+auf bekannte Fehler hingewiesen.
+
+\begin{enumerate}
+  \item {\bf Zeilenabstand}
+
+        Es wird mit einfachem Grundzeilenabstand geschrieben.
+
+  \item {\bf Anschriftenfeld}
+
+        Die Angaben im Anschriftenfeld werden auf
+        folgende Weise gegliedert:
+        \begin{enumerate}
+          \item Sendungsart, Versendungsform, Vorausverf"ugung
+          \item Leerzeile
+          \item Empf"angerbezeichnung
+          \item Postfach oder Stra"se und Hausnummer
+          \item Leerzeile
+          \item Postleitzahl und Bestimmungsort
+          \item Leerzeile
+          \item Bestimmungsland
+        \end{enumerate}
+
+        Bei Auslandsanschriften ist die Leerzeile zwischen
+        der Zeile mit Postfach oder Stra"se und Hausnummer
+        und der Zeile mit dem Bestimmungsort entbehrlich,
+        wenn das Bestimmungsland unter der entsprechenden
+        Zeile angegeben werden mu"s.
+
+        Im Verkehr mit bestimmten L"andern kann auf die
+        Angabe des Bestimmungslandes verzichtet werden,
+        wenn das Unterscheidungskennzeichen f"ur den
+        grenz"uberschreitenden Kraftfahrzeugverkehr
+        der Postleitzahl --- durch einen Bindestrich
+        getrennt --- vorangestellt wird.
+
+% \iffalse
+        Nach dem ersten Eintrag im Anschriftenfeld
+        darf nur ein \verb|\\| stehen. Direkte
+        L"angenangaben (z.B.\ \verb|\\[\medskipamount]|)
+        sind nicht zul"assig und verursachen einen Fehler.
+        Der Fehler kann umgangen werden, indem eine

+  \item {\bf Bezugszeichen und Tagangabe}
+
+        Die Eintragungen in dieser Zeile werden automatisch
+        an der richtigen Stelle plaziert.
+
+  \item {\bf Betreff und Teilbetreff}
+
+        Betreff und Teilbetreff sind stichwortartige
+        Inhaltsangaben. Der Betreff bezieht sich auf den
+        ganzen Brief, Teilbetreffe beziehen sich auf
+        Briefteile.
+
+        Der {\em Wortlauf des Betreffs\/} wird ohne
+        Schlu"spunkt geschrieben.
+% \iffalse
+        Der {\em Teilbetreff\/} beginnt an der Fluchtlinie
+        (linker Rand), schlie"st mit einem Punkt und wird
+        unterstrichen. Wir empfehlen diesen Text besser
+        durch eine andere Schriftart (z.B.\ fett)
+        hervorzuheben. Der Text wird unmittelbar angef"ugt.
+% \fi
+  \item {\bf Behandlungsvermerke}
+
+        Behandlungsvermerke (z.B.\ eilt) werden
+        neben das Anschriftenfeld, beginnend auf
+        Grad 50 (bei einer 10er Teilung), oder im
+        Anschlu"s an die Betreffangabe geschrieben;
+        sie k"onnen hervorgehoben werden.
+
+  \item {\bf Anlagen- und Verteilvermerke}
+
+        Anlagen- und Verteilvermerke beginnen an der
+        Fluchtlinie oder auf Grad 50 (60 oder 75).
+        Die vorliegende Version des `mpdinbriefs'
+        unterst"utzt nur Anlagen- und Verteilvermerke
+        auf der Fluchtlinie.
+
+        Der Anlagenvermerk geht dem Verteilvermerk
+        voraus.
+
+  \item {\bf Postscriptum}
+
+        Die DIN Norm 5008 sieht kein Postscriptum vor.
+        Die vorliegende Version des `mpdinbriefs'
+        unterst"utzt trotzdem ein Postscriptum.
+        Wir empfehlen das Postscriptum unmittelbar
+        nach der Gru"sformel \verb|\closing| oder
+        nach Anlagen- und Verteilvermerken zu setzen.
+
+  \item {\bf Seitennumerierung}
+
+        Die Seiten eines Schriftst"ucks sind von der
+        2.~Seite an oben fortlaufend zu benummern.
+        Die Pagestyles \verb|headings| und
+        \verb|contheadings| unterst"utzen diese
+        Forderung. Das Verfahren ist jedoch noch nicht
+        befriedigend.
+
+  \item {\bf Hinweis auf Folgeseiten}
+
+        Wenn der Text eines Schriftst"ucks eine n"achste
+        Seite beansprucht, wird empfohlen
+        \begin{itemize}
+          \item am Fu"s der bereits beschrifteten Seite,
+          \item nach der letzten Textzeile,
+          \item mit mindestens einer Leerzeile Abstand,
+          \item auf Grad 60 (72 oder 90) beginnend,
+        \end{itemize}
+        als Hinweis auf die folgende Seite drei Punkte
+        zu schreiben.
+
+        Dieses Vorgehen wird zur Zeit nicht unterst"utzt.
+        Der Pagestyle \verb|contheadings| schreibt jedoch
+        an das Ende der laufenden Seite die Seitenzahl
+        der Folgeseite und auf Folgeseiten die
+        aktuelle Seite in der Kopf der Seite.
+
+        Die Kombination des Befehls \verb|\bottomtext|,
+        zum Einblenden einer weiteren Kommunikationszeile
+        am unteren Blattende der ersten Seite sowie
+        von gesellschaftsrechtlichen Angaben,
+        mit Seitenstilen, die die Fu"szeile unten mit
+        der Seitennummer oder Folgeseitennummer
+        beschriften, hat unter Umst"anden zur Folge,
+        da"s die Seiten- oder Folgeseitennummer
+        von diesen Feldern "uberschrieben wird.
+
+  \item {\bf Kommunikationszeile am Blattende und
+        gesellschaftsrechtliche Angaben}
+
+        Eine Kommunikationszeile am Blattende kann die folgenden
+        Angaben enthalten: Gesch"aftsr"aume, Telefon, Telefax,
+        Teletex, Telex, Btx und Kontoverbindungen.
+
+        Bei Kapitalgesellschaften sind die Angaben "uber
+        \begin{itemize}
+          \item die Rechtsform und den Sitz der Gesellschaft,
+          \item das Registergericht des Sitzes der Gesellschaft
+                und die Nummer, unter der die Gesellschaft in
+                das Handelsregister eingetragen ist,
+          \item den Namen des Vorsitzenden des Aufsichtsrates
+                (sofern die Gesellschaft nach gesetzlicher
+                Vorschrift einen Aufsichtsrat zu bilden hat),
+          \item die Namen des Vorsitzenden und aller Mitglieder
+                des Vorstandes (bei Gesellschaften mit
+                beschr"ankter Haftung die Namen der
+                Gesch"afts\-f"uhrer),
+        \end{itemize}
+        am Fu"s des Vordrucks aufzuf"uhren.\hfil\break
+        Die Rechtsform kann auch im Briefkopf als Bestandteil
+        der Firma angegeben werden.
+\end{enumerate}
+
+\ssect{Adre"s--Etiketten}
+Das Ausdrucken von Adre"s-Etiketten ist w"unschenswert, wenn
+keine Fensterbriefh"ullen verwendet werden. Damit das Bedrucken
+von verschiedenen Etiketts"atzen m"oglich wird, kann die Breite
+und H"ohe der einzelnen Etiketten mit den Befehlen
+\verb|\setlabelwidth|\arg{Breite} und
+\verb|\setlabelheight|\arg{H"ohe} eingestellt
+werden. Der obere Rand kann mit dem Befehl
+\verb|\setlabeltopmargin|\arg{oberer Rand} festgelegt werden.
+Die Anzahl der Labels in einer Spalte wird durch den Befehl
+\verb|\setlabelnumber|\arg{Anzahl} angegeben. Die mehrfache
+Verwendung eines Etikettenblatts wird durch den Befehl
+\verb|\spare|\arg{Anzahl} m"oglich. Dieser Befehl r"uckt
+den Druckbeginn um {\em Anzahl\/} Positionen vor.
+Die Ausgabe der Adre"s--Etiketten erfolgt spaltenweise.
+
+In vielen Druckern bleiben die Etikettenbl"atter h"angen,
+wenn die Tr"agerfolie in beiden Spalten freiliegt. Drucker,
+die alternativ einen ebenen Papiertransport besitzen, sollten
+zur Ausgabe von Etiketten auf diesen umgeschaltet werden.
+
+\ssect{Kompatibilit"at zu Rainer Sengerlings `dinbrief'}
+Im Jahr 1992 wurde an der Universit"at Karlsruhe ein Briefstil
+entwickelt, dem der Namen `dinbrief' gegeben wurde. Im gleichen
+Jahr ver"offentlichte Rainer Sengerling einen Briefstil unter
+dem gleichen Namen.
+
+Rainer Sengerling hat darauf verzichtet seinen Briefstil
+an \LaTeXe\ anzupassen. Daraufhin haben wir den Briefstil
+`dinbrief' im Dezember 1994 als \LaTeXe-Klasse ver"offentlicht.
+Die beiden Briefstile haben unterschiedliche Befehlss"atze,
+was bei vielen Benutzern zu Verwirrung und Irritationen
+gef"uhrt hat. Wegen der unterschiedlichen Befehle der beiden
+Stile haben uns viele Anfragen erreicht. Die jetzt vorliegende
+Fassung stellt beide Befehlss"atze zur Verf"ugung und f"uhrt die
+bisher unabh"anigen Briefstile zusammen.
+
+Gegenw"artig wird die Klassenoption \verb|german| nicht ausgewertet
+und f"uhrt zu einer Warnung. Alternativ mu"s mit dem Befehl
+\begin{quote}
+  \verb|\usepackage{german}|\\
+\end{quote}
+der Stil "`{\tt german}"' geladen werden.

+\begin{description}
+
+  \item[\cmd\Retouradresse\arg{{Absenderadresse im Brief\kern 0pt fenster}}]
+        Der Befehl legt die Anschrift des Absenders oben im
+        Anschriftenfeld des Briefs fest.
+
+  \item[\cmd\Retourlabel] \hfil\break
+        Dieser Befehl erzeugt Absenderadre"s-Etiketten, falls
+        die Erzeugung der Etiketten aktiviert wurde.
+
+        Ferner wird die Ausgabe der \cmd\Retouradresse\ unterdr"uckt.
+
+        {\bf Dieser Befehl wird gegenw"artig nicht unterst"utzt und

+
+  \item[\cmd\Fenster] \hfil\break
+        Bei der Verwendung von Fensterbriefh"ullen wird die mit

+        (Absenderadresse) oben im Anschriftenfeld eingeblendet,
+        falls der Befehl \cmd\Fenster\ angegeben wurde. Ferner
+        werden die Faltmarken am linken Rand ausgegeben.
+
+        Daf"ur wird die Ausgabe der Etiketten unterdr"uckt.
+

+
+  \item[\cmd\Postvermerk\arg{Postvermerk}] \hfil\break
+        Dieser Befehl vereinbart Vermerke f"ur den
+        Postversand wie z.B.\ Einschreiben.
+
+  \item[\cmd\Behandlungsvermerk\arg{Behandlungsvermerk}] \hfil\break
+        Der Befehl \cmd\Behandlungsvermerk\ dient zur
+        Angabe von (man wirds kaum glauben) Behandlungsvermerken
+        wie z.B.\ Eilt, pers"onlich oder "`F"ur die unterste
+        Schublade"'.
+
+  \item[\cmd\Absender\arg{Name und Adresse des Absenders}] \hfil\break
+        Die Adresse des Absenders wird vereinbart.
+        Dieser Befehl gilt f"ur den laufenden und alle
+        weiteren Briefe; er gilt solange, bis ein
+        weiterer \cmd\Absender- oder \cmd\address-Befehl
+        angegeben wird.
+
+  \item[\cmd\Absender\arg{Teil 1::Teil 2}] \hfil\break
+        Dies ist eine Sonderform des \cmd\Absender-Befehls.
+        Der durch \verb|::| abgetrennte {\em Teil2\/}
+        erscheint im Briefkopf, aber nicht im
+        Absenderetikett, falls ein solches mit dem
+        Befehl \cmd\Retourlabel\ angefordert
+        wurde.
+
+        Dieser Befehl wird korrekt unterst"utzt. Da aber
+        der Befehl \cmd\Retourlabel\ nicht implementiert
+        wurde, hat die Aufteilung im Moment praktisch keine
+        Bedeutung; sie kann aber in sp"ateren Versionen
+        wieder notwendig sein.
+
+  \item[\cmd\Datum\arg{Briefdatum}] \hfil\break
+        Soll als Absendedatum {\sl nicht\/} das aktuelle
+        Tagesdatum (des Rechners) eingesetzt werden, kann
+        mit diesem Befehl das Datum explizit angegeben werden.
+
+        Der Befehl \cmd\heute\ wird nicht unterst"utzt.
+
+  \item[\cmd\Betreff\arg{{Betreff}}] \hfil\break
+        Mit diesem Befehl wird der Betreff gesetzt, der den
+        Empf"anger "uber den Gegenstand des Briefes
+        informiert. Der Betreff kann ein oder mehrzeilig sein.
+
+  \item[\cmd\Einrueckung\arg{Text}] \hfil\break
+        Der Text wird um $1 in$ einger"uckt und geht bis zum
+        rechten Rand. Der Text darf Abs"atze enthalten.
+
+  \item[\cmd\anlagenrechts] \hfil\break
+        Die Anlagen- und Verteilvermerke beginnen {\sl rechts\/}
+        neben der Gru"sformel auf Grad 50. Mit diesem Befehl
+        kann Platz gespart werden, falls die Seite fast voll
+        ist, und kein neues Blatt begonnen werden soll.
+        Dieser Befehl mu"s vor \cmd\closing\ stehen.
+        Die Anlagen- und Verteilvermerke m"ussen in diesem
+        Fall ebenfalls vor dem \cmd\closing-Befehl stehen.
+
+  \item[\cmd\Anlagen\arg{Anlagenvermerk}] \hfil\break
+        Mit diesem Befehl werden eventuelle Anlagenvermerke
+        vereinbart oder gesetzt. Dieser Befehl darf sowohl
+        vor dem \cmd\closing-Befehl als auch hinter diesem
+        stehen. Der Anlagenvermerk wird nur vereinbart falls
+        der Befehl vor dem \cmd\closing-Befehl angegeben wird.
+        Der Anlagenvermerk wird sofort ausgegeben und gesetzt,
+        falls der Befehl nach dem \cmd\closing-Befehl angegeben
+        wird.
+
+  \item[\cmd\Verteiler\arg{Verteilvermerk}] \hfil\break
+        Dieser Befehl vereinbart oder setzt Verteilvermerke.
+        Die Ausf"uhrungen zum \cmd\Anlagen-Befehl gelten
+        auch f"ur diesen Befehl.
+
+  \item[\cmd\Etihoehe\arg{H"ohe eines Adressetiketts}] \hfil\break
+        Verschiedene Herstelle vertreiben Adressetiketten,
+        die alle ein bischen anders sind. Um den Briefstil
+        an unterschiedlich hohe Adre"setiketten anzupassen,
+        kann mit dem Befehl \cmd\Etihoehe\ die H"ohe eines
+        Etiketts angegeben werden.
+
+  \item[\cmd\Etirand\arg{oberer Rand}] \hfil\break
+        Die B"ogen mit den Adre"setiketten haben oft einen
+        Versatz oder oberen Rand. Mit dem Befehl \cmd\Etirand\
+        kann dieser Versatz eingestellt werden.
+
+  \item[\cmd\Etizahl\arg{Zahl der Etiketten}] \hfil\break
+        Auf ein Blatt mit Adre"setiketten passen leider
+        nicht beliebig viele sondern nur eine begrenzte
+        Anzahl von Etiketten, die sich dann auch nicht kunterbunt
+        auf dem Blatt tummeln, sondern Spaltenweise angeordnet
+        sind. Die Zahl der Etiketten, die in eine Spalte
+        passen werden durch den Befehl \cmd\Etizahl\
+        angegeben.
+
+  \item[\cmd\spare\arg{{n}}] \hfil\break
+        Das Bedrucken der Adre"setiketten beginnt nach {\em n\/}
+        leeren Adre"slabeln. Die Label werden spaltenweise
+        durchgez"ahlt.

+% is running under LaTeX 2.09 or \LaTeXe\ and which font selection
+% scheme is in use.
+%
+% |\ifka@db@ltxtwoe| is true if and only if this style is running in
+% an \LaTeXe-environment. |\ifka@db@nfss| is true if we are using an
+% NFSS 1 and \linebreak[4]
+% |\ifka@db@nfsstwo| is true if we are using the NFSS 2.

+%
+% \begin{macro}{\@ptsize}
+% \begin{macro}{\ds@12pt}
+% \begin{macro}{\ds@11pt}
+% \begin{macro}{\ds@10pt}
+% \begin{macro}{\ds@norm}
+%    The control sequence |\@ptsize| is used to store the second digit
+%    of the pointsize we are typesetting in. So, normally, it's value
+%    is one of 0, 1 or 2.
+%
+%    To be compatible with the old `dinbrief', pointsize 3 is used to
+% \iffalse
+%    switch to special size having $\frac{1}{6}$ in as |\baselineskip|.
+% \fi
+%    switch to a special size setting exactly 6 lines per inch.
+%    (\dots\ it's used to feature some other size following the rules
+%    of old stupid typewriters).
+%
+%    The type size options are handled by defining |\@ptsize| to contain
+%    the last digit of the size in question and branching on |\ifcase|
+%    statements. This is done for historical reasons to stay compatible
+%    with other packages that use the |\@ptsize| variable to select
+%    special actions.
+%
+%    To follow the programming conventions of \LaTeXe, we split the
+%    definition of the macros into two parts. One for the old \LaTeX\
+%    and one for \LaTeXe.
+%
+%    \begin{macrocode}
+\ifka@db@ltxtwoe

+%
+% \subsection{Defining the jobname}
+%
+% \begin{macro}{\jobname@aux}
+% \begin{macro}{\jobname@lbl}
+%    This control sequence is used to store the name of the aux-file.
+%    Therefore character |_| temporally is given catcode 12.
+%
+%    \begin{macrocode}
+{%
+  \catcode`\_=12
+  \gdef\jobname@aux{\jobname.aux}% .aux or _aux or ...

+%
+% \begin{macro}{\if@restonecol}
+%    If the document has to be printed in two columns, we sometimes

+%    remember to switch back.
+%    \begin{macrocode}
+\newif\if@restonecol
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{Setting paper sizes}
+%
+%    The variables |\paperwidth| and |\paperheight| should reflect the
+%    physical paper size after trimming. For desk printer output this
+%    is usually the real paper size since there is no post-processing.
+%    \begin{macrocode}
+\ifka@db@ltxtwoe
+  \DeclareOption{a4paper}
+     {\setlength\paperheight {297mm}%
+      \setlength\paperwidth  {210mm}}

+      \setlength\paperwidth  {7.25in}}
+\fi
+%    \end{macrocode}
+%
+%  \subsection{Two-side or one-side printing}
+%
+%    Sometimes it's necessary to have two-sided printing. For example
+%    if you have a two-sided printer, and you write two letters the
+%    first one having an odd number of pages. The second then starts
+%    on the backside of the last page of the first letter. To avoid
+%    this problem you can specify the twoside option. Each letters
+%    then starts on a new sheet on a two-sided printer.
+%
+%    \begin{macrocode}
+\ifka@db@ltxtwoe
+  \DeclareOption{twoside}{\@twosidetrue}
+\fi
+\@twosidefalse
+%    \end{macrocode}
+%
+%  \subsection{Draft option}
+%
+%    If the user requests \Lopt{draft} we show any overfull boxes.
+%    We could probably add some more interesting stuff to this option.
+%    \begin{macrocode}
+\def\ds@draft{\overfullrule 5pt}
+\def\ds@final{\overfullrule 0pt}
+%    \end{macrocode}
+%
+%  \subsection{Twocolumn printing}
+%
+%    Two-column and one-column printing is again realized via a switch.
+%
+%    This makes no sense in letters following the rules of DIN. But
+%    maybe it is sometimes usefull.
+%
+%    Some labels use twocolumn output.
+%    \begin{macrocode}
+\ifka@db@ltxtwoe
+  \DeclareOption{onecolumn}{\@twocolumnfalse}
+  \DeclareOption{twocolumn}{\@twocolumntrue}
+\fi
+%    \end{macrocode}
+%
+%  \subsection{Defining internal font selection commands}
+%
+%  To be compatible to all font selection schemes we define our own
+%  font selection commands |\ka@db@fontshape| (1), |\ka@db@fontseries| (1),
+%  |ka@db@fontsize| (2), |\ka@db@selectfont| (0).
+%
+% Note: In the definition of the original \LaTeX\ 2.09 font selection system
+%       the command |\rm| is used. This causes no error because |\rm| is
+%       well defined in this version of \LaTeX.
+%
+% \iffalse
+% Note: The code for the font selection with the original mechanism
+%       had been written by K.~Braune.
+% \fi

+%    \end{macrocode}
+%
+% \subsection{Executing options}
+%
+%    Here we execute the default options to initialize certain
+%    variables.
+%    \begin{macrocode}
+\ifka@db@ltxtwoe
+  \ExecuteOptions{a4paper,10pt,onecolumn,final}
+\fi
+%    \end{macrocode}
+%
+%    The |\ProcessOptions| command causes the execution of the code
+%    for every option \Lopt{FOO}
+%    which is declared and for which the user typed
+%    the \Lopt{FOO} option in his
+%    |\documentclass| command.  For every option \Lopt{BAR} he typed,
+%    which is not declared, the option is assumed to be a global option.
+%    All options will be passed as document options to any
+%    |\usepackage| command in the document preamble.
+%
+%    In the old \LaTeX\ the user starts his file with the command
+%    \linebreak[4]|\documentstyle [OPTION1, ... ,OPTIONk]{STYLE}|
+%    which saves the |OPTION|'s and |\input|'s the file |STYLE.STY|.
+%    When the |STYLE.STY| file issues the command |\@options|, the
+%    following happens for each i:
+%
+%    If the control sequence |\ds@OPTIONi| is defined then
+%    execute this option |\ds@OPTIONi|. In the other case
+%    save OPTIONi on a list of unprocessed options.
+%
+%    After |STYLE.STY| has been executed, the file |OPTIONi.STY| is read for
+%    each |OPTIONi| on the list of unprocessed options.
+%
+%    \begin{macrocode}
+\ifka@db@ltxtwoe
+    \ProcessOptions

+%
+%  The `mpdinbrief' class/style file does not load additional packages.
+%  The user should load `german.sty'.

+\ifka@db@ltxtwoe
+%    \end{macrocode}
+%  Here we supply the declarative font changing commands that were common
+%  in \LaTeX\ version 2.09 and earlier. These commands work in text mode
+%  \textit{and} in math mode. They are provided for compatibility, but one
+%  should start using the |\text...| and |\math...| commands instead.
+%  These commands are redefined using |\@renewfontswitch|, a command
+%  with three arguments: the user command to be defined, \LaTeX's command
+%  to be executed in text mode, and \LaTeX's command to be executed in math
+%  mode.
+%

+%  \end{macro}
+%  \end{macro}
+%  \end{macro}
+%

+%  And the commands to change the shape of the font. The slanted and

+%
+%  \subsubsection{different labelstyles}
+%  This version of the mpdinbrief supports different styles for labels.
+%  This allows the generation of papers containing several labels or
+%  printing directly on envelopes. The control sequence |\labelstyle|
+%  allows to change the layout.
+%
+%  For each layout two control sequences |\label@|STYLENAME and \hfil\break
+%  |\lstyle@|STYLENAME have to be defined. |\label@|STYLENAME
+%  is called from |\mlabel| for each label and has to typeset
+%  this label. |\lstyle@|STYLENAME is called from |\startlabels|
+%  and has to do the general setup (for example changing the
+%  page layout).
+%
+%  It is very difficult to say which counters and lengths have
+%  to redefined in this macros.
+%
+% \begin{macro}{\labelstyle}
+%   |\labelstyle| is a command to define the layout of the labels.
+%   Normally, labels are printed on special paper, but some printers
+%   are able to print on envelopes. Therefore we define some styles
+%   for printing labels on envelops:
+%
+%   \medskip

+%       \multicolumn{2}{c}{Briefh\"ullenformat} &
+%         \multicolumn{2}{c}{Gebr\"auchliches}\\

+%  \begin{macro}{lt@state}
+%  The counter |c@lt@state| holds values from 0 to 3. These
+%  values indicate different states inside the letter.
+%
+%  \smallskip
+%  \begin{tabular}{cl}
+%    0  & We are outside the letter environment.\\
+%    1  & We are between \verb.\begin{letter}. and \verb.\opening.\\
+%    2  & We are between \verb.\opening. and \verb.\closing.\\
+%    3  & We are between \verb.\closing. and \verb.\end{letter}.\\
+%  \end{tabular}
+%  \smallskip
+%
+%  This counter should replace the old boolean flag |\ifka@db@inletter|.
+%  We further use the different states to change the behavior of some
+%  API macros. This is necessary because the {\tt old dinbrief\/}
+%  requests to have \cmd\Anlagen\ and \cmd\Verteiler\ beeing in front of
+%  \cmd\closing. And our implementation wants to have \cmd\encl\
+%  and \cmd\cc\ after the \cmd\closing{}-command.

+% \subsubsection{Controlling the generation of labels}
+%  \cmd\makelabels\ is a preamble command to enable the generation
+%  of labels. To control the generation of labels for single
+%  letters, we provide three other commands. This commands
+%  work only if \cmd\makelabels\ is given in the preamble.
+%
+%  The other three commands \cmd\nolabels, \cmd\offlabels\ and
+%  \cmd\onlabels, which only work if \cmd\makelabels\ had
+%  been given in the preamle, control the generation of
+%  single or in case of \cmd\offlabels\ the remaining
+%  label(s). \cmd\nolabels\ avoids the label for the current
+%  letter. Further if the generation of labels was permanently
+%  disabled with \cmd\offlabels\ this also switches the generation
+%  of labels from the next letter on.
+%  \cmd\offlabels\ stops the generation of labels.
+%  \cmd\onlabels\ switch the generation of label on again.
+%
+%  The counter \cmd\c@labelgen\ indicates the current state
+%  of the generation of labels:
+%
+%    \begin{tabular}{cp{0.75\textwidth}}
+%      0 & generation of labels is switched off\\
+%      1 & generation of current label is beeing temporary switched off\\
+%      2 & generation of labels is in force\\

+% \subsection{Lists}
+%
+% \subsubsection{General list parameters}
+%
+% The following commands are used to set default values for the list
+% environment's parameters. See the \LaTeX{} manual for an explanation
+% of the meanings of these parameters.  Defaults for the list
+% environment are set as follows.  First, |\rightmargin|,
+% |\listparindent| and |\itemindent| are set to 0pt.  Then, for a Kth
+% level list, the command |\@listK| is called, where `K' denotes `i',
+% '`i', ... , `vi'.  (I.e., |\@listiii| is called for a third-level
+% list.)  By convention, |\@listK| should set |\leftmargin| to
+% |\leftmarginK|.
+%
+% \begin{macro}{\leftmargin}
+% \begin{macro}{\leftmargini}
+% \begin{macro}{\leftmarginii}
+% \begin{macro}{\leftmarginiii}
+% \begin{macro}{\leftmarginiv}
+% \begin{macro}{\leftmarginv}
+% \begin{macro}{\leftmarginvi}
+% For efficiency, level-one list's values are defined at top level, and
+% |\@listi| is defined to set only |\leftmargin|.
+%
+%    \begin{macrocode}
+\leftmargini 2.5em
+\leftmarginii 2.2em
+\leftmarginiii 1.87em
+\leftmarginiv 1.7em
+\leftmarginv 1em
+\leftmarginvi 1em
+%    \end{macrocode}
+%    Here we set the top level leftmargin.
+%    \begin{macrocode}
+\leftmargin\leftmargini
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\labelsep}
+% \begin{macro}{\labelwidth}
+%    |\labelsep| is the distance between the label and the text of an
+%    item; |\labelwidth| is the width of the label.
+%    \begin{macrocode}
+\labelwidth\leftmargini

+%
+%
+% \subsubsection{Enumerate}
+%
+%    The enumerate environment uses  four counters: \Lcount{enumi},
+%    \Lcount{enumii}, \Lcount{enumiii} and \Lcount{enumiv}, where
+%    \Lcount{enumN} controls the numbering of the Nth level
+%    enumeration.
+%
+% \begin{macro}{\theenumi}
+% \begin{macro}{\theenumii}
+% \begin{macro}{\theenumiii}
+% \begin{macro}{\theenumiv}
+%    The counters are already defined in \file{latex.tex}, but their
+%    representation is changed here.
+%
+%    \begin{macrocode}
+\def\theenumi{\arabic{enumi}}
+\def\theenumii{\alph{enumii}}
+\def\theenumiii{\roman{enumiii}}
+\def\theenumiv{\Alph{enumiv}}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\labelenumi}
+% \begin{macro}{\labelenumii}
+% \begin{macro}{\labelenumiii}
+% \begin{macro}{\labelenumiv}
+%    The label for each item is generated by the commands \hfil\break
+%    |\labelenumi| ... |\labelenumiv|.
+%    \begin{macrocode}
+\def\labelenumi{\arabic{enumi}.}
+\def\labelenumii{(\alph{enumii})}
+\def\labelenumiii{\roman{enumiii}.}
+\def\labelenumiv{\Alph{enumiv}.}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \begin{macro}{\p@enumii}
+% \begin{macro}{\p@enumiii}
+% \begin{macro}{\p@enumiv}
+%    The expansion of |\p@enumN||\theenumN| defines the output of a
+%    |\ref| command when referencing an item of the Nth level of an
+%    enumerated list.
+%    \begin{macrocode}
+\def\p@enumii{\theenumi}
+\def\p@enumiii{\theenumi(\theenumii)}
+\def\p@enumiv{\p@enumiii\theenumiii}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Itemize}
+%
+% \begin{macro}{\labelitemi}
+% \begin{macro}{\labelitemii}
+% \begin{macro}{\labelitemiii}
+% \begin{macro}{\labelitemiv}
+% Itemization is controlled by four commands: |\labelitemi|,
+% |\labelitemii|, |\labelitemiii|, and |\labelitemiv|, which define
+% the labels of thevarious itemization levels: the symbols used are
+% bullet, bold en-dash, asterisk and centred dot.
+%
+%    \begin{macrocode}
+\def\labelitemi{$\bullet$}
+\def\labelitemii{\bf --}
+\def\labelitemiii{$\ast$}
+\def\labelitemiv{$\cdot$}
+%    \end{macrocode}

+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Description}
+%
+% \begin{macro}{\description}
+% \begin{macro}{\descriptionlabel}
+% \begin{macro}{\enddescription}
+%    The description environment is defined here -- while the itemize
+%    and enumerate environments are defined in \file{latex.tex}.
+%
+%    To change the formatting of the label, you must redefine
+%    |\descriptionlabel|.
+%
+%    \begin{macrocode}
+\def\descriptionlabel#1{%
+  \hspace\labelsep \bf #1}
+\def\description{%
+  \list{}{\labelwidth\z@ \itemindent-\leftmargin
+          \let\makelabel\descriptionlabel}}
+\let\enddescription\endlist
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Verse}
+%
+% \begin{macro}{\verse}
+% \begin{macro}{\endverse}
+%   The verse environment is defined by making clever use of the
+%   list environment's parameters.  The user types |\\| to end a line.
+%   This is implemented by |\let|'ing |\\| equal |\@centercr|.
+%
+%    \begin{macrocode}
+\def\verse{\let\\=\@centercr
+  \list{}{\itemsep\z@
+          \itemindent -15pt
+          \listparindent \itemindent

+          \advance\leftmargin 15pt}\item[]}
+\let\endverse\endlist
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Quotation}
+%
+% \begin{macro}{\quotation}
+% \begin{macro}{\endquotation}
+%   The quotation environment is also defined by making clever use of
+%   the list environment's parameters. The lines in the environment
+%   are set smaller than |\textwidth|. The first line of a paragraph
+%   inside this environment is indented.
+%
+%    \begin{macrocode}
+\def\quotation{%
+  \list{}{\listparindent 1.5em
+          \itemindent\listparindent
+          \rightmargin\leftmargin}%
+  \item[]}
+\let\endquotation=\endlist
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \subsubsection{Quote}
+%
+% \begin{macro}{\quote}
+% \begin{macro}{\endquote}
+%   The quote environment is like the quotation environment except
+%   that paragraphs are not indented.
+%
+%    \begin{macrocode}
+\def\quote{%
+  \list{}{\rightmargin\leftmargin}%
+  \item[]}
+\let\endquote=\endlist
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+%
+% \subsection{Setting parameters for existing environments}
+%
+% \subsubsection{Array and tabular}
+%
+% \begin{macro}{\arraycolsep}
+%    The columns in an array environment are separated by
+%    2|\arraycolsep|.
+%    \begin{macrocode}
+\arraycolsep 5pt
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\tabcolsep}
+%    The columns in an tabular environment are separated by
+%    2|\tabcolsep|.
+%    \begin{macrocode}
+\tabcolsep 6pt
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\arrayrulewidth}
+%    The width of rules in the array and tabular environments is given
+%    by \hfil\break
+%    |\arrayrulewidth|.
+%    \begin{macrocode}
+\arrayrulewidth .4pt
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\doublerulesep}
+%    The space between adjacent rules in the array and tabular
+%    environments is given by |\doublerulesep|.
+%    \begin{macrocode}
+\doublerulesep 2pt
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Tabbing}
+%
+% \begin{macro}{\tabbingsep}
+%    This controls the space that the |\'| command puts in. (See
+%    \LaTeX{} manual for an explanation.)
+%    \begin{macrocode}
+\tabbingsep \labelsep
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Minipage}
+%
+% \begin{macro}{\@minipagerestore}
+%    The macro |\@minipagerestore| is called upon entry to a minipage
+%    environment to set up things that are to be handled differently
+%    inside a minipage environment. In the current styles, it does
+%    nothing.
+% \end{macro}
+%
+% \begin{macro}{\@mpfootins}
+%    Minipages have their own footnotes; |\skip||\@mpfootins| plays
+%    the same r\^ole for footnotes in a minipage as |\skip||\footins| does
+%    for ordinary footnotes.
+%
+%    \begin{macrocode}
+\skip\@mpfootins = \skip\footins
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Framed boxes}
+%

+% \subsection{Footnotes}
+%
+% \begin{macro}{\footnoterule}
+%    Usually, footnotes are separated from the main body of the text
+%    by a small rule. This rule is drawn by the macro |\footnoterule|.
+%    We have to make sure that the rule takes no vertical space (see
+%    \file{plain.tex}) so we compensate for the natural heigth of the
+%    rule of 0.4pt by adding the right amount of vertical skip.
+%
+%    To prevent the rule from colliding with the footnote we first add
+%    a little negative vertical skip, then we put the rule and make
+%    sure we end up at the same point where we begun this operation.
+%    \begin{macrocode}
+\def\footnoterule{%
+  \kern-1\p@
+  \hrule width .4\columnwidth
+  \kern .6\p@}
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\c@footnote}
+%    The mpdinbrief style/class does not use this macro.
+%
+%    (Footnotes are numbered within chapters in the report and book
+%    document styles.)
+% \end{macro}
+%
+% \begin{macro}{\@makefntext}
+%    The footnote mechanism of \LaTeX{} calls the macro |\@makefntext|
+%    to produce the actual footnote. The macro gets the text of the
+%    footnote as its argument and should use |\@thefnmark| as the mark
+%    of the footnote. The macro |\@makefntext| is called when
+%    effectively inside a |\parbox| of width |\columnwidth| (i.e.,
+%    with |\hsize| = |\columnwidth|).
+%
+%   An example of what can be achieved is given by the following piece
+%   of \TeX\ code.
+%    \begin{macrocode}
+%          \long\def\@makefntext#1{%
+%             \@setpar{\@@par
+%                      \@tempdima = \hsize
+%                      \advance\@tempdima-10pt
+%                      \parshape \@ne 10pt \@tempdima}%
+%             \par
+%             \parindent 1em\noindent
+%             \hbox to \z@{\hss$\m@th^{\@thefnmark}$}#1}
+%    \end{macrocode}
+%    The effect of this definition is that all lines of the footnote
+%    are indented by 10pt, while the first line of a new paragraph is
+%    indented by 1em. To change these dimensions, just substitute the
+%    desired value for `10pt' (in both places) or `1em'.  The mark is
+%    flushright against the footnote.
+%
+%    In this document class we use a simpler macro, in which the
+%    footnote text is set like an ordinary text paragraph, with no
+%    indentation except on the first line of a paragraph, and the
+%    first line of the footnote. Thus, all the macro must do is set
+%    |\parindent| to the appropriate value for succeeding paragraphs
+%    and put the proper indentation before the mark.
+%
+%    \begin{macrocode}
+% \long\def\@makefntext#1{%
+%     \parindent 1em%
+%     \noindent
+%     \hbox to 1.8em{\hss$\m@th^{\@thefnmark}$}#1}
+%    \end{macrocode}

+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@makefnmark}
+%    The footnote markers printed in the text to point to the
+%    footnotes should be produced by the macro |\@makefnmark|. We use
+%    the default definition for it.

+%  \begin{macro}{\@answertonew}
+%  The draft proposal of the new DIN 676 has an additional
+%  field for the name of a person who has written the letter.
+%
+%  The new DIN 676 (draft) has a big disadvantage. The referline
+%  is larger than the normal \cmd\textwidth.  In dinbrief there has been 
+%  added some extra space to this box to conform to this. 
+%  Mpdinbrief deviates from the DIN and adjusts the referline to \cmd\textwidth.
+%  The whitespace between the fields is equally spread.
