% Es werden diverse Dateien erzeugt: \texttt{plenDINde.mp},

% mit
% \begin{flushleft}
% \texttt{mpost --tex=latex} \meta{mp-file}

% geladen werden. Es kann aber auch mit
% \begin{flushleft}
% \texttt{mptopdf} \meta{1-Datei}
% \end{flushleft}
% eine PDF-Datei erzeugt werden.
%
% Anpassungen werden ausschließlich in der \texttt{dtx}-Datei vorgenommen!
% Wesentlich ist dabei der Abschnitt \texttt{main}.

% \section{Der Abschnitt \texttt{main}}
% Diese Abschnitt erzeugt die Haupttreiberdateien, die dann mit \texttt{mpost}
% bearbeitet werden.
%
% Hinweise zu den Variablen:
% \begin{itemize}
% \item \texttt{input pllcoDIN} oder \texttt{input pllcoSN}\hfill\\
%   legt fest, ob die Maße für Briefe nach DIN oder SN
%   geladen werden. Damit kann gewählt werden, welches Layout
%   verdeutlicht werden soll. Sollen die Längen eingezeichnet werden,
%   ist pllcoDIN zu verwenden.
% \item \texttt{grafikhoehe}\hfill\\
%   legt die Höhe der Ausgabedatei fest.
% \item \texttt{strichstaerke}\hfill\\
%   bestimmt die Stiftbreite, die zum Zeichnen des
%   Briefbogens, der Faltmarken und der From-Rule benutzt wird.
% \item \texttt{framestrichstaerke}\hfill\\
%   bestimmt die Stiftbreite zum Zeichnen der
%   Element-Rahmen (nicht der Hilfsrahmen).
% \item \texttt{hilfsstrichstaerke}\hfill\\
%   bestimmt die Stiftbreite zum Zeichnen der
%   Bemaßung und der Hilfsrahmen.
% \item \texttt{tickhoehe}\hfill\\
%   legt die Höhe der vertikalen Linien horizontaler
%   Bemaßung fest (Makro hmeasure). Die Maßlinie wird auf halber Höhe
%   von tickhoehe gezeichnet. Für die Makros vmeasure und dmeasure gilt
%   ähnliches. In dmeasure wird jedoch ein Vielfaches von tickhoehe
%   verwendet.
% \item \texttt{framed} und \texttt{filled}\hfill\\ 
%   legen fest, ob die Elemente mit einem Rahmen
%   versehen bzw. gefüllt werden sollen.
% \item \texttt{drawcolor}\hfill\\
%   legt die Farbe von Linien und Text fest.
% \item \texttt{fillcolor}\hfill\\
%   legt die Füllfarbe fest, falls filled=true ist.
% \item \texttt{latexlengths}\hfill\\
%   legt fest, ob die unveränderlichen LaTeX-Längen
%   angezeigt werden sollen.
% \item \texttt{latexlengthcolor}\hfill\\
%     legt die Farbe fest, mit der LaTeX-Längen
%   gezeichnet werden.
% \item \texttt{language}\hfill\\
%   legt die Sprache der Beschreibung fest.
% \item \texttt{ahlength}\hfill\\
%   Da foldmarkhpos sehr klein ist, können sich bei kleinen Grafiken
%   die Pfeilspitzen der Bemaßung berühren. Um das zu verhindern, kann
%   mit der MetaPost-internen Variablen ahlength die Pfeillänge
%   verringert werden.
