% Das \microtype\ Paket stellt eine \LaTeX\ Schnittstelle für die mikrotypographischen
% Erweiterungen von \pdftex bereit: besonders markant Zeichenvorsprünge und Fontexpansion,
% weiterhin die Justierung von Zeichenabständen innerhalb Wörter und zusätzliches Kerning sowie
% durch Bindestrich trennbaren Sperrsatz (Tracking) und die Möglichkeit, alle oder ausgewählte
% Ligaturen abzuschalten.
% Es erlaubt, diese Features auf anpassbare Fonts anzuwenden und alle mikrotypographischen Aspekte
% dieser Fonts in einer einfachen und flexiblen Art und Weise zu konfigurieren. Einstellungen
% für verschiedene Schriftarten werden bereitgestellt.\footnote{
%   Zur Zeit stellt dieses Paket Protrusionseinstellungen für Computer Modern
%   Roman, Palatino, Times, &lt;URW&gt; Garamond, Adobe Garamond und Minion,
%   Bitstream Charter und Letter Gothic, die &lt;AMS&gt; Symbole und Euler Fonts,
%   verschiedene Eurosymbol Schriftarten, sowie einige allgemeine Einstellungen für unbekannte Schriftarten
%   (siehe~Tabelle~\ref{tab:fonts} auf Seite~\pageref{tab:fonts}) bereit.
%   Beisteuerungen sind gern gesehen.}
%
% Zu beachten ist, dass Fontexpansion und Zeichenvorsprünge nur mit 
% \pdftex ($\geq$ Version 0.14f) arbeiten. Automatische Fontexpansion erfordert mindestens
% Version 1.20 oder neuer. Ligaturen zu deaktivieren erfordert \pdftex\ 1.30, Sperrsatz und 
% die Justierung von Zeichenabständen innerhalb Wörter sowie Kerning erfordern Version 1.40. Das
% Paket aktiviert standardmäßig Protrusion und Expansion, falls sicher angenommen werden kann, dass diese
% funktionieren. Diese beiden Features sind ebenso verfügbar mit \luatex. Das
% \microtype\ Paket arbeitet nicht mit \xetex.
%
% Das alternative Paket \letterspace, welches ebenso mit einfachem \TeX arbeitet,

%\section{Mikrotypographie mit \pdftex}\label{sec:micro-type}
%
% \pdftex, die \TeX\ Erweiterung geschrieben von \thanh, führt eine Reihe 
% mikrotypographischer Features ein. welche es nicht nur zum Werkzeug der Wahl 
% für die Erstellung elektronischer Dokumente, sondern auch Werke überragender, altehrwürdiger
% Typographie machen: am bedeutendsten \textit{Zeichenvorsprünge (Character Protrusion, auch bekannt als margin kerning)}
% und\textit{Fontexpansion}. \thanh s Thesis zitierend:
%
%\changes{v1.9b}{2006/01/13}{add samples of micro-typographic features}
%\microtypesample{\small
% `Margin kerning bezeichnet die Justierung der Zeichen an den Rändern (margin) eines
%  gesetzten Textes. Eine vereinfachte Anwendung von Margin kerning ist hängende
%  Zeichensetzung. Margin kerning ist notwendig für optische Ausrichtung der Ränder
%  eines gesetzten Textes, weil mechanisches Angleichen der Ränder diese eher stümperhaft
%  aussehen lässt. Einige Zeichen können eine Zeile für das menschliche Auge kürzer
%  erscheinen lassen als andere. Solche Zeichen um einen passenden Betrag zu den Rändern zu
%  verschieben würde das Aussehen des Textes massiv verbessern.
%
%  Mit Fontexpansion zu verfassen ist die Methode, eine weitere oder engere 
%  Variante des Fonts zu erschaffen, welche die Wortzwischenräume mehr ausgleichen. 
%  Eine Schriftart in einer losen Zeile kann durch eine weitere Variante ausgetauscht werden, sodass die Wortzwischenräume
%  weniger stark gestreckt werden. Gleichermaßen kann ein Font in einer dicht bepackten Zeile 
%  durch eine schmalern Variante ersetzt werden, um die Abstände zu verringern.
%  Es besteht mit Sicherheit die potentielle Gefahr der Fontdeformierung wenn 
%  solche Manipulationen vorgenommen werden, weshalb sie mit extremer Vorsicht vorgenommen
%  werden müssen. Das Potential, eine Zeilebreite mittels Fontexpansion zu justieren,
%  sollte bedacht werden, wenn ein Paragraph in Zeilen zerbrochen wird,
%  um bessere Stopppunkte zu wählen.' [\cite[p.~323]{ThanhThesis}]} ~\\
%
% Diesen beiden Features fehlte seit einiger Zeit eine einfache \LaTeX\ Benutzerschnittstelle.
% Dann wurde das \cite{pdfcprot} Paket veröffentlicht, welches
% \LaTeX\ Benutzern ermöglichte, Zeichenvorsprünge zu benutzen, ohne sich zu sehr 
% mit den Interna beschäftigen zu müssen.
%
% Fontexpansion allerdings war weiterhin schwierig zu utilisieren, da es erforderte,
% dass die Fontmetriken für alle Ebenen der Erweiterung verfügbar waren.
% Deswegen musste jeder, der von diesem Feature Gebrauch machen wollte, im Vorfeld
% multiple Ausführungen der Schriftarten anfertigen. Shellskripte, um den Benutzer wenigstens
% teilweise von dieser Last zu befreien, waren verfügbar~-- dennoch blieb es eine lästige Arbeit.
% Darüber hinaus mussten alle Fonts weiterhin physisch erstellt werden, wodurch Kompilierungszeit 
% und Speicherplatz auf der Festplatte verschwendet wurden.
%
% Im Sommer 2004 implementierte \thanh\ eine Besonderheit, welche sich als eine
% bedeutende Erleichterung für \TeX\ und \LaTeX\ Benutzer entpuppte: Fontexpansion kann nun
% automatisch stattfinden. Das heißt, \pdftex\ braucht nicht länger die Fontmetriken der expandierten
% Schriftart, sondern berechnet diese zur Laufzeit und komplett im Speicher.
%
%\bigskip\noindent
% Nach diesem großen Sprung in der Anwendbarkeit stoppte die Entwicklung nicht.
% Im Gegenteil, \pdftex\ wurde mit immer mehr besonderen Merkmalen ausgestattet: Version
% 1.30 führte die Möglichkeit ein, \emph{alle Ligaturen auszuschalten}, Version 1.40
% brachte ein robustes \emph{Letter-spacing} Kommando, die Möglichkeit
% \emph{zusätzliches Zeichen Kerning} zu spezifizieren und die \emph{Justierung von Zeichenabständen innerhalb Wörter}.
%
% Robustes und per Bindestrich trennbares \emph{Letter-spacing (Tracking)} war immer
% extrem schwierig in \TeX zu realisieren. Obwohl das \cite{soul} Paket
% große Mühen unternahm um es möglich zu machen, konnte es trotzdem weiterhin in 
% bestimmten Situationen scheitern; allein das Tracking einer Schriftart für das ganze
% Dokument blieb unmöglich. Wendet man die neue Erweiterung von \pdftex an, stellt dies
% nicht länger ein Problem dar. Das \microtype\ Paket stellt die Möglichkeit bereit,
% das Tracking anpassbarer Fontsets zu ändern, z.B., alle kleinen Kapitälchen.
% Es führt außerdem die zwei neuen Kommandos \cs{textls} und \cs{lsstyle}
% für ad-hoc Letter-spacing ein, welche wie normale Textkommandos benutzt werden können.
% Beachten Sie, dass Letter-spacing nur im &lt;PDF&gt; Modus funktioniert.
%
% \emph{Zusätzliches kerning} für Zeichen einer Schriftart einzustellen ist besonders
% nützliche für Sprachen, deren typographische Tradition es erfordert, bestimmte Zeichen
% durch ein Leerzeichen abzutrennen. Es ist zum Beispiel üblich, in französischer
% Typographie ein wenig Platz vor einem Fragezeichen, Ausrufezeichen und Semikolon zu lassen,
% und ein wenig mehr Platz vorm Doppelpunkt und den Guillemets. Bis jetzt konnte das nur 
% erreicht werden, indem man diese Zeichen aktivierte (z.B.
% mit dem \pkg{babel} Paket), was nicht immer eine praxistaugliche Lösung sein kann.
% Im Kontrast zum Standard Kerning, welches in die Schriftarten eingebaut ist
% (und welches natürlich wie üblich greift), basiert dieses Kerning auf einzelnen Zeichen
% nicht auf Zeichenpaaren.
%
% \emph{Wortzwischenräume zu justieren} basiert auf der Idee, dass - um eine 
% uniforme Grauheit in einem Text zu erreichen - die Wortzwischenräume auch von den
% Zeichen in der direkten Umgebung abhängen sollten. Wenn zum Beispiel ein Wort mit 
% einem `r' endet, sollte der folgende Abstand ein kleines bisschen kleiner sein als z.B. nach
% einem `m'. Man kann von diesem Konzept wie von einer Erweiterung von \TeX s `space
% factors' denken. Allerdings, während space factors alle drei Parameter dieser
% Wortzwischenräume (oder Haftung) um den selben Betrag beeinflusst~-- das Kerning, den maximalen
% Betrag, um den der Zwischenraum gestreckt oder geschrumpft werden kann
% ~-- stellt \pdftex\ die Möglichkeit bereit, diese Parameter unabhängig voneinander
% zu modifizieren. Darüber hinaus können die Werte für jeden Font anders eingestellt werden.
% Außerdem -- und vielleicht am wichtigsten -- können diese Parameter nicht nur erhöht sondern
% auch erniedrigt werden. Dieses Merkmal wird das Aussehen von Paragraphen vielleicht noch
% mehr aufwerten.
% Die Betonung liegt im letzten Satz auf dem Wort `vielleicht': diese Erweiterung ist immer 
% noch sehr experimentell -- speziell haben nur die letzten Zeichen im Moment Einfluss auf die Wortzwischenräume.
% Außerdem sind die mit \microtype\ gelieferten Einstellungen nicht mehr als eine erste Annäherung,
% weshalb ich es begrüßen würde, wenn Sie Korrekturen und Verbesserungen vornehmen.
% Ich würde vorschlagen, die Begründung für die Einstellungen in Abschnitt~\ref{sub:conf-spacing} durchzulesen.
%
% Abschließend mag die Möglichkeit, für einen Font \emph{alle Ligaturen auszuschalten},
% nützlich für Schreibmaschinenschriftarten sein.

%\begin{itemize}
%  \item Das entsprechende mikrotypograpische Feature einschalten, entweder
%        mittels der respektiven package Option oder mittels des \cs{microtypesetup} Kommandos
%        (Abschnitt~\ref{sec:options}).
%  \item Wählen Sie die Schriftarten aus, auf welche dieses Feature angwendet werden soll, indem
%        Sie `Font Sets' deklarieren und aktivieren. Einige Sets sind vorerstellt und können direkt
%        in den Paketoptionen aktiviert werden
%        (Abschnitt~\ref{sec:font-sets}).
%  \item Feinabstimmen der mikrotypographischen Einstellungen an den Schriftarten oder Sets von Schriftarten
%        (Abschnitt~\ref{sec:fine-tuning}).
%  \item Falls sie der Typ sind, der immer weiter marschiert, werden
%        Sie sicher an der Möglichkeit zu Context-abhängigen Einstellungen interessiert sein
%        (Abschnitt~\ref{sec:context}).
%  \item Wir ermutigen Sie sogar, den Pfad typographischer Tugend zu verlassen 
%        und ein paar Schafe zu stehlen (section~\ref{sec:lettersp}) oder auf andere Weise einzudringen
%        (section~\ref{sec:disable-ligatures}).
%  \item Sollten sich Ihnen ein Hindernis auftun, folgen Sie den Tipps und Warnungen
%        (Abschnitt~\ref{sec:caveats}).
%\end{itemize}
%
%
%\section{Optionen}\label{sec:options}
%
% Wie viele andere \LaTeX\ Pakete auch akzeptiert das \microtype\ Paket Optionen
% über die bekannte |Schlüssel=Wert| Syntax. Im Folgenden finden sie eine Beschreibung aller
% \key{Schlüssel} und ihrer möglichen |Werte|
% (`|true|' kann ausgelassen werden; multiple Werte (falls erlaubt) müssen eingeklammert
% werden; der Standardwert wirds rechts gezeigt, angeführt von einem Sternchen 
% falls es abhängig von der \pdftex\ Version und/oder dem Output Modus ist).
%
%
%\subsection{Die mikro-typographischen Features anschalten}\label{sub:options-microtype}
%
%\Describe{Option}{protrusion}
%                 {*true,false,compatibility,nocompatibility,:Name des Font Sets}
%\DescribeOption{expansion}
% Dies sind die hauptsächlichen Optionen um die Ebene mikro-typographischer Verfeinerung,
% welche die Schriftarten in ihrem Dokument erhalten sollten, zu kontrollieren. 
% Standardmäßig ist das Paket recht gierig; Character Protrusion ist aktiviert, Fontexpansion
% wird nur in Situationen abgeschaltet, in denen \pdftex\ die Fonts nicht automatisch expandieren
% kann, also falls es entweder zu alt ist (Versionen vor 1.20) 
% oder falls der Output Modus &lt;DVI&gt; ist (siehe Abschnitt~\ref{sub:options-misc}).
% Anders  gesagt wird \microtype\ versuchen, soviel Mikrotypographie anzuschalten wie
% es sicher als funktionierend unter den gegebenen Bedingungen erwarten kann
% (und normalerweise ist es nicht nötig, das Paket mit anderen Optionen für die &lt;PDF&gt;
% bzw. &lt;DVI&gt; Modi zu laden).
%
% Protrusion und Expansion können getrennt (de)aktiviert werden, indem man den betreffenden
% Schlüssel auf |true| bzw. |false| setzt. Die
% \opt{activate} Option
%\DescribeOption{activate}
% kürzt das Setzen beider Optionen zur gleichen Zeit ab. Deswegen haben die folgenden Zeilen
% alle denselben Effekt (wenn man &lt;PDF&gt; Dateien mit einer aktuellen Version
% von \pdftex erstellt):
%\begin{verbatim}
%\usepackage[protrusion=true,expansion]{microtype}
%\end{verbatim}
%\begin{verbatim}
%\usepackage[activate={true,nocompatibility}]{microtype}
%\end{verbatim}
%\begin{verbatim}
%\usepackage{microtype}
%\end{verbatim}
%\smallskip
% Wenn \pdftex\ Fontexpansion und Character Protrusion verwendet, können Zeilenumbrüche
% (und konsequenterweise auch Seitenumbrüche) unterschiedlich ausfallen. Wenn das nicht gewünscht ist
%  -- weil sie z.B. ein Buch neu setzen, dessen Seitenumbrüche sich nicht ändern dürfen --
%  können Sie den Wert |compatibility| an die \opt{protrusion}
% und/oder \opt{expansion} Optionen hängen. Aus typographischer Sicht jedoch werden die Ergebnisse
% suboptimal sein, weshalb der Wert standardmäßig |nocompatibility| ist.
%
% Abschließend können Sie auch den Namen eines Font Sets angeben, auf welches
% Character Protrusion und/oder Fontexpansion beschränkt werden sollten, siehe auch
% Abschnitt~\ref{sec:font-sets} für eine detaillierte Beschreibung. Spezifizieren eines Font Sets
% für ein Features aktiviert dieses Features implizit mit.
%
%\medskip
%\Describe{Option}{tracking}{true,!false,:font set name}
%\DescribeOption{kerning}
%\DescribeOption{spacing}
% Es existiert keine Kompatibilitätsebene für die neuen Erweiterungen Tracking,

% und standardmäßig aktivierten mikro-typographischen Features für die
% relevanten \pdftex\ Versionen und Output Modi.
%
%\medskip\noindent
% Ob Ligaturen deaktiviert werden sollten kann nicht mittels einer Option kontrolliert werden,

%
%
%\subsection{Zeichenvorsprünge}\label{sub:options-protrusion}
%
%\Describe{Option}{factor}{:integer}[1000]
% Benutzen Sie diese Option, um global einzustellen, um welchen Betrag die Zeichen
% hervorragen sollen. Während ein Wert von 1000 bedeutet, dass der volle Vorsprung 
% wie in der Konfiguration (siehe Abschnitt~\ref{sub:protrusion}) spezifiziert benutzt wird,
% bedeutet ein Wert von 500 entsprechend die Halbierung der Protrusion.
% Dies kann nützlich sein, falls Sie grundsätzlich zufrieden mit den Einstellungen sind,
% aber bevorzugen, wenn die Zeichenhervorragungen weniger oder mehr zu sehen sind.
% (z.B. wenn sie so stolz darauf sind, dieses Feature nutzen zu können, dass sie es jedem 
% zeigen wollen, oder -- um eine Motivation zu nennen, die in Einverständnis mit typographischer
% Korrektheit steht -- falls sie eine große Schriftart nutzen, die gemäßigtere Vorsprünge verlangt).
%
%\medskip

% Diese Option wird in Abschnitt~\ref{sub:protrusion} erklärt, ebenso das Kommando
% \cs{SetProtrusion}. Seien sie vorsichtig bei Benutzung dieser Optionen!

%\subsection{Fontexpansion}\label{sub:options-expansion}
%
%\Describe{Option}{auto}{*true,false}
% Wie bereits im Kapitel~\ref{sec:micro-type} angemerkt, können die expandierten Versionen
% der Fonts automatisch erstellt werden. Diese Option ist standardmäßig an, wenn
% \pdftex Version 1.20 oder höher beträgt und der Output Modus &lt;PDF&gt; ist;
% ansonsten ist die Option deaktiviert.
% Falls \opt{auto} auf false gesetzt ist, müssen die einzelnen Fonts aller Expansionsstufen
% bereits existieren (mit nach dem Schema \meta{font~name}\texttt{\textpm}\meta{expansion value} benannten Dateien,
% z.B. \file{cmr12+10}, wie beschrieben in \cite{pdftexman}).
%\iffalse ^^A no longer true (1.40?)
% Falls expandierte Instanzen der Fonts verfügbar sind, werden sie verwendet,
% egal ob \opt{auto} auf true oder false gesetzt ist.

%\changes{v1.9}{2005/08/27}{add remark about Type\,1 fonts required for
%                           automatic font expansion}
% Automatische Fontexpansion funktioniert nicht mit Bitmap Fonts, weswegen Sie, falls Sie
% die Computer Modern Roman Fonts in &lt;T1&gt; Kodierung\footnote{
%     Beiläufig bemerkt, Type\,1 Format und &lt;T1&gt; Encoding hängen in keiner
%     Weise miteinander zusammen, abgesehen davon, dass beide mit einem `T' anfangen und mit einer `1' enden.},
% nutzen, entweder \pkg{cm-super} Fonts installieren oder die Latin Modern
% Fonts (package \pkg{lmodern}) benutzen sollten.
%
%\medskip
%\Describe{Option}{stretch}{:integer}[20]
%\DescribeOption{shrink}
% Sie können bestimmen, wie sehr ein Font maximal gestreckt bzw. geschrumpft werden kann.
% Die Zahl wird durch 1000 dividiert, sodass ein Stretch Limit von 10 bedeutet,
% dass ein Font um bis zu ~1\% expandiert werden kann. 
% Das standardmäßige Stretch Limit ist 20; das Shrink Limit ist standardmäßig gleich
% dem Stretch Limit.
%
%\medskip
%\Describe{Option}{step}{:integer}[\MaybeDefault{1}]
% Fonts werden nicht um beliebige Mengen expandiert, sondern nur um gewisse bestimmte
% Schritte innerhalb der Expansionslimits.Mit aktuellen Version von \pdftex\ (1.40 oder
% neuer) ist diese Option standardmäßig auf 1 gesetzt, damit \pdftex\ die
% maximale Anzahl an Instanzen der jeweiligen Fonts ausprobieren kann und somit den bestmöglichen
% Output garantiert.\footnote{
%   Die Kehrseite an dieser Standardeinstellung ist, dass \pdftex\ vielleicht bei großen Dokumenten
%   nicht genügend Speicher zur Verfügung hat; in diesem Falle sollten Sie über die Fehlermeldungen in der `Hints
%   and caveats' Abschnitt~(\ref{sec:caveats}) nachlesen oder es mit einem größeren \opt{step} probieren.}
% Ältere \pdftex\ Versionen jedoch mussten jede einzelne Fontinstanz in der
% &lt;PDF&gt; Datei einfügen, wodurch die Dateigröße teils dramatisch erhöht wurde. Deswegen --
% sollten Sie eine pre-1.40 \pdftex\ Version nutzen -- ist \opt{step} standardmäßig
% auf ein Fünftel des kleineren Wertes von \opt{stretch} und \opt{shrink} gesetzt.
%
%\medskip
%\Describe{Option}{selected}{true,!false}
% Wenn Fontexpansion angewendet wird ist es möglich, die Expansion einiger sensibler Zeichen,
% welche schnell deformiert erscheinen können (z.B. das `O' im Kontrast zum `I'), zu begrenzen.
% Das nennt sich \emph{selected expansion} und seine Benutzung erlaubt, die Stretch und Shrink
% Limits zu erhöhen (auf z.B. 30 anstelle von 20); allerdings ist der Zuwachs limitiert, da
% gleichzeitig die durchschnittliche Stretch Varianz verringert wird
% Deswegen ist diese Option standardmäßig auf
% |false| gesetzt, sodass alle Zeichen um denselben Betrag expandiert werden.
% Siehe Abschnitt~\ref{sub:expansion} für eine detailliertere Beschreibung.
%
%
%\subsection{Tracking/Letterspacing}\label{sub:option-tracking}
%
%\Describe{Option}{letterspace}{:integer}[100]
% Diese Option verändert den Standardbetrag fürs Tracking (siehe Abschnitt~\ref{sub:tracking})
% sowie Letterspacing (siehe Abschnitt~\ref{sec:lettersp}). Der Betrag wird in Tausendsteln
% von 1\,em angegeben; zulässige Werte sind im Bereich von \textminus1000
% bis +1000.
%
%
%\subsection{Verschiedene Optionen}\label{sub:options-misc}
%
%\Describe{Option}{DVIoutput}{true,*false}
% \pdftex\ ist nicht bloß in der Lage, &lt;PDF&gt; Dateien zu erstellen, sondern kann auch &lt;DVI&gt;
% Dateien erzeugen.\footnote{
%    Neuere \TeX\ Systeme benutzen \pdftex\ als Standard Engine auch für
%    &lt;DVI&gt; Ausgaben.}
% Letztere können mit der Option \opt{DVIoutput} erzwungen werden, was 
% \cmd\pdfoutput\ auf Null setzt.
%
%\changes{v1.5}{2004/12/15}{add note about \opt{DVIoutput} option}
% Beachten Sie, dass dies Pakete verwirren wird, die auf den Wert von
% \cmd\pdfoutput\ angewiesen sind, falls diese früher geladen wurden; so erwarten sie,
% dass sie aufgerufen wurden um eine &lt;PDF&gt; Ausgabe zu erzeugen, obwohl das nicht der Fall ist.
% Diese Pakete sind u.a.: \pkg{graphics}, \pkg{color},
% \pkg{hyperref}, \pkg{pstricks} und natürlich \pkg{ifpdf}. Entweder laden sie diese Pakete nach
% \microtype\ oder benutzen die Anweisung |\pdfoutput=0| früher
% -- in letzterem Fall ist die \opt{DVIoutput} Option redundant.
%
% Wenn man &lt;DVI&gt; Dateien erstellt, muss Fontexpansion explizit aktiviert werden.
% Weder Letterspacing noch \emph{automatische} Fontexpansion werden funktionieren, da
% die postprocessing Treiber (|dvips|, |dvipdfm| etc.) sowie die &lt;DVI&gt; Betrachter
% nicht in der Lage sind, die Fonts on the fly zu generieren.

%\medskip
%\Describe{Option}{draft}{true,!false}
%\DescribeOption{final}
% Falls die \opt{draft} Option an das Paket geleitet wird, werden \emph{alle
% mikro-typographischen Erweiterungen ausgeschaltet}, was zu unterschiedlichen Zeilen-
% und somit Seitenumbrüchen führen kann. Die \opt{draft} und \opt{final} Optionen können
% außerdem von den Optionen der Klasse geerbt werden; natürlich kann man diese mit den
% Optionen der Pakete überschreiben. Falls man z.B. die Klassenoption |draft| verwendet, um
% jegliche übervollen Boxen anzuzeigen, sollte man \microtype\ mit der |final|
% Option laden.
%
%\medskip
%\Describe{Option}{verbose}{true,!false,errors,silent}
% Informationen bzgl. der Einstellungen an jeglichen Fonts werden in die Log Datei
% geschrieben, sofern man die \opt{verbose} Option aktiviert. Wenn \microtype\ auf ein nicht-fatales Problem trifft
% (z.B. ein unbekanntes Zeichen in den Einstellungen oder nicht-existente Einstellungen),
% gibt es standardmäßig nur eine Warnung aus und versucht weiterzumachen.
% Lädt man das Paket mit |verbose=errors| werden alle Warnungen in Fehler verwandelt, sodass
% man sicher sein kann, dass kein Problem unerkannt bleibt. Falls man
% andererseits allen Warnungen nachgegangen ist und sich entscheidet, diese zu ignorieren,
% kann man \microtype\ mittels |verbose=silent| zum Schweigen bringen.
%
%\medskip
%\Describe{Option}{babel}{true,!false}
% Das Paket mit der \opt{babel} Option zu laden wird die Zeichensetzung 
% der jeweiligen ausgewählten Sprache anpassen. Mehr Information hierzu in Abschnitt~\ref{sec:context}.
%
%\medskip
%\Describe{Option}{config}{:file name}[microtype]
% Verschiedene Einstellungen für dieses Paket werden aus einer Hauptkonfigurationsdatei geladen,
% standardmäßig ist dies \file{microtype.cfg} (siehe Abschnitt~\ref{sub:config-file}).
% Sie können eine andere Konfigurationsdatei wählen, indem sie deren Name
% mittels \emph{ohne die Dateiendung} angeben, z.B. |config=mycrotype|.
%
%\iffalse ^^A ... waiting for bug reports before documenting yet another option ...
%\medskip
%\Describe{Option}{defersetup}{!true,false}
% Anders als in früheren Versionen verzögert \microtype\ seit Version 1.9a sein
% Setup bis zum Ende der Präambel. Dies hat mindestens 2 Vorteile: Das unten
% beschriebene Kommando \cs{microtypesetup} kann genutzt werden um Paketoptionen später
% zu ändern und es ist nicht länger notwendig, die Standardfonts und Enkodierungen
% noch vor \microtype zu laden. Es gibt nur ein mögliches Problem: Falls eine Box
% innerhalb der Präambel konstruiert wird \emph{und} diese Box eine Schriftart enthält, 
% die nicht geladen wird bevor die Box im Dokument verwendet wird, so wird diese Schriftart
% nicht eingerichtet. Sollte dieser extrem unwahrscheinliche Fall auftreten, sollten Sie
% |defersetup=false| setzen. Dann greifen jedoch die angesprochenen Restriktionen.
%
%\medskip
%\Describe{Option}{copyfonts}{true,!false} ^^A and another one ...
% There are some restrictions as to what \pdftex\ can do with a font: Firstly,
% it cannot expand a single font with different parameters, secondly, it cannot
% apply different protrusion settings to one font within the same paragraph.
% Both restrictions, which only matter with a context-sensitive setup
% (cf.~section~\ref{sec:context}), can be circumvented with the \opt{copyfonts}
% option: when it is set to |true|, \microtype\ will use font copies to work
% on. This option will automatically be set to |true|, whenever protrusion or
% expansion settings with a |context| keyword are encountered. If these
% settings are loaded after the preamble, however, it is too late, and you
% should set the \opt{copyfonts} option manually.
% This only works with \pdftex\ 1.40.4 or later.

%\subsection{Changing options later}\label{sub:options-cmd}
%
%\Describe{Macro}{\microtypesetup}{key\,|=|\,value list}
% Innerhalb der Präambel akzeptiert dieses Kommando alle oben genannten Paketoptionen
% (außer |config|).
% Im Dokumentkörper kann dieser Aufruf verwendet werden, um grundlegende Einstellungen
% der mikro-typographischen Erweiterungen zu verändern. Es akzeptiert dann alle Optionen aus
% Abschnitt~\ref{sub:options-microtype}: \key{expansion}, \key{protrusion} und
% \key{activate}, welche wiederum die Werte |true|, |false|,
% |compatibility| oder |nocompatibility| erhalten können, \key{tracking}, \key{kerning} und
% \key{spacing} mit den zulässigen Werten |true| oder |false|.
% Den Namen eines Fonts an die Option zu leiten ist nicht erlaubt.
% Benutzt man dieses Kommando, so könnte man z.B. temporär Fontexpansion ausschalten
% indem man wie folgt verfährt:
%\begin{verbatim}
%\microtypesetup{expansion=false}
%\end{verbatim}
%
%
%\section{Fonts für Mikrotypographie auswählen}\label{sec:font-sets}
%
% Standardmäßig wird Character Protrusion auf alle Textschriftarten angewandt, die
% im Dokument genutzt werden, und eine grundlegende Auswahl an Fonts wird Fontexpansion
% unterzogen. Sie wollen vielleicht anpassen, welche Schriftarten den Vorzug bekommen sollten,
% mikro-typographisch behandelt zu werden. Dies kann geschehen, indem man 
% `Font Sets' deklariert und auswählt; diese Font Sets werden mittels Font Attributen spezifiziert,
% die zutreffen müssen.
%
%\medskip
%\Describe{Macro}{\DeclareMicrotypeSet}{?features,set name,set of fonts}
%\DescribeMacro{\DeclareMicrotypeSet*}
% Dieses Kommando deklariert ein neues Font Set, auf welches die the mikro-typographischen
% Erweiterungen angewendet werden. Das optionale Argument kann eine mit Komma separierte
% Liste von Features enthalten, auf die das jeweilige Set beschränkt werden soll.
% Die mit Stern versehene Variante deklariert \emph{und} aktiviert das Font Set
% gleichzeitig.
%
% \paragraph{Das Font Set} wird durch den &lt;NFSS&gt; Font Attributen zugewiesene Werte definiert:
% Kodierung, Familie, Serie, Form und Größe (siehe auch~\cite{fntguide}).
% Wir fangen mit einem Beispiel an. Dieses Paket definiert einen Font namens
% `|basictext|' in der Hauptkonfigurationsdatei wie folgt:
%\begin{verbatim}
%\DeclareMicrotypeSet{basictext}
%   { encoding = {OT1,T1,T2A,LY1,OT4,QX,T5},
%     family   = {rm*,sf*},
%     series   = {md*},
%     size     = {normalsize,footnotesize,small,large}
%   }
%\end{verbatim}
% Wenn Sie nun 
%\begin{verbatim}[deletekeywords={[1]{protrusion}}]
%\UseMicrotypeSet[protrusion]{basictext}
%\end{verbatim}
% in der Präambel des Dokuments aufrufen, werden nur Fonts mit den Kodierungen &lt;OT1&gt;, &lt;T1&gt;,
% &lt;T2A&gt;, &lt;LY1&gt;, &lt;OT4&gt;, &lt;QX&gt; oder &lt;T5&gt; aus Roman oder Sans Serif Familien, normalen (oder
% `medium') Serien und in per \cmd\normalsize, \cmd\footnotesize, \cmd\small\ oder \cmd\large 
%  aufgerufenen Größen hervorragen. Mathematische Schriftarten andererseits
% werden das nicht, da sie anderen Kodierungen angehören; gleiches gilt für 
% fettgedruckte oder große Schriftarten etc.
%
% Falls eine Attributsliste leer ist oder fehlt -- wie das `shape' Attribut
% im obigen Beispiel -- führt dies zu keiner Einschränkung, sprich, es ist äquivalent dazu
% \emph{alle} möglichen Werte für dieses Attribut einzusetzen.
% Deswegen ist das vordefinierte Set `|alltext|', welches wie folgt deklariert ist:
%\begin{verbatim}
%\DeclareMicrotypeSet{alltext}
%   { encoding = {OT1,T1,T2A,LY1,OT4,QX,T5,TS1} }
%\end{verbatim}
% viel weniger restriktiv. Die einzige Bedingung lautet, dass die Kodierung stimmen muss.
%
% Folgt einem Wert ein Asterisk (wie `|rm*|' und `|sf*|' im ersten Beispiel),
% kennzeichnet dieser keinen &lt;NFSS&gt; Code, sondern wird in das
% |\|\meta{value}|default| des Dokuments übersetzt, z.B. \cmd\rmdefault.\footnote{
%   Diese Übersetzungen geschehen zum \cmd\AtBeginDocument, was bedeutet, dass
%   Änderungen an den Standardwerten innerhalb der Präambel auch berücksichtigt werden.
%   Nur falls Font Standards \cmd\AtBeginDocument\ vom Benutzer selbst geändert werden,
%   müssen Sie \microtype\ nach diesen Änderungen laden.}
% Ein einzelner Asterisk bedeutet |\|\meta{attribute}|default|, z.B.
% \cmd\encodingdefault, gleichermaßen \cmd\normalsize\ für die Größenachse.
% Größen können entweder als Dimension angegeben werden (`|10|' oder `|10pt|') oder
% als Größenwahlkommando \emph{ohne} den Backslash. Sie können sogar Bereiche
% (z.B. `|small-Large|') wählen; während die untere Grenze im Bereich enthalten ist, gilt
% dies nicht für die obere Grenze. Deshalb würde `|12-16|' beispielsweise 12\,pt,
% 13.5\,pt und 15.999\,pt enthalten, aber nicht 16\,pt. Es ist nicht erlaubt, die untere
% oder obere Grenze auszulassen (`|-10|', `|large-|').
%
% Zusätzlich zu diesem Deklarationsschema können sie einzelne Schriften zu einem
% Set hinzufügen, indem Sie den `|font|' Schlüssel nutzen, welcher die Aneinanderreihung aller
% Fontattribute, getrennt durch Slashes, erwartet, das heißt,
%`|font|\,|=|\,\meta{encoding}|/|\meta{family}|/|\meta{series}|/|\meta{shape}|/|\meta{size}'.
% Das erlaubt uns, Font Sets zu Sets hinzuzufügen, von denen sie sonst disjunkt sind.
% Falls Sie zum Beispiel wollen, dass die Roman Familie in allen Größen hervorragt,
% aber nur die normal große, möglicherweise kursive typewriter Font (im Kontrast zum
% z.B. kleinen Font), so könnten sie das Set so deklarieren:
%\begin{verbatim}[deletekeywords={[1]{protrusion}}]
%\DeclareMicrotypeSet[protrusion]
%   { myset }
%   { encoding = T1,
%     family   = rm*,
%     font     = {T1/tt*/m/n/*,
%                 T1/tt*/m/it/*} }
%\end{verbatim}
% Wie Sie dem Beispiel entnehmen können, ist die Asterisk Notation auch für
% den |font| Schlüssel zulässig. Ein einzelner Asterisk ist äquivalent zu `|*/*/*/*/*|', also dem
% normalen Font. Befehle zur Größenwahl sind auch möglich, allerdings sind keine Bereiche erlaubt. 
%
%\medskip\noindent
% Tabelle~\ref{tab:predefined-font-sets} listet die 9 vordefinierten Font Sets auf.
% Diese können ebenfalls aktiviert werden, indem ihr Name an die Optionen
% \opt{protrusion}, \opt{expansion}, \opt{tracking}, \opt{kerning} und
% \opt{spacing} der Features geleitet wird, wenn das Paket geladen wird, z.B.:

% Die Kodierung muss immer stimmen.

%\subsection{Character Protrusion}\label{sub:protrusion}
%
%\Describe{Macro}{\SetProtrusion}{?options,set of fonts,protrusion settings}
% Benutzt man dieses Kommando, so kann man die Protrusionsfaktoren jedes einzelnen Zeichens
% einer Schriftart oder eines Font Sets verändern. Ein sehr unvollständiges Beispiel wäre das folgende:
%\begin{verbatim}
%\SetProtrusion
%   { encoding = T1,
%     family   = cmr }
%   { A              = {50,50},
%     \textquoteleft = {700, } }
%\end{verbatim}
% Dies würde darin resultieren, dass der Buchstabe `A' um 5\% seiner Breite
% auf beiden Seiten hervorragt; das linke Anführungszeichen würde hier um 70\% seiner Breite zum linken Rand hin
% hervorragen. Angewandt wird das Beispiel auf alle Font Formen, Serien und Größen der
% &lt;T1&gt;~kodierten Computer Modern Roman Familie.
%
%\paragraph{Die Protrusionseinstellungen}
% bestehen aus \meta{Zeichen}\,|=|\,\meta{Protrusionsfaktoren} Paaren.
%
% Die Zeichen können entweder einzeln als solche angegeben werden (`|A|'),
% als ein Symbolkommando (`\cmd\textquoteleft'), oder als Slotnummer: 3 Stellen
% für dezimale Notation, angeführt von~|"| für hexadezimal, mit~|'| für
% oktal (z.B. die `fl' Ligatur in &lt;T1&gt; Kodierung:~|029|, |"1D|, |'35|).
% \mbox{8-bit} (und sogar &lt;UTF-8&gt;) Zeichen können direkt oder in
% \LaTeX's traditioneller \mbox{7-bit} Notation eingegeben werden: sowohl |\"A| als auch \expandafter|\"A|
% sind zulässig, vorausgesetzt, dass das Zeichen sowohl in der Input- als auch
% der Fontkodierung deklariert wird. Sie haben ebenfalls die Möglichkeit, Zeichenlisten anzugeben,
% für welche die Einstellungen übernommen werden sollen (siehe Abschnitt~\ref{sub:inherit}).
%
% Die Protrusionsfaktoren weisen einem Zeichen den Betrag zu,
% um den sie zum linken Rand hin (erster Wert) bzw. rechten Rand hin (zweiter Wert) hervorragen
% sollen. Standardmäßig sind die Werte relativ zur Breite des Zeichens zu verstehen,
% sodass ein Wert von 1000 bedeutet, dass das Zeichen vollständig zwischen die Ränder
% gelegt werden sollte, während es z.B. bei einem Wert von 50 
% um 5\% seiner Breite hervorragen würde. Negative Werte sind erlaubt, ebenso Zahlen größer
% als 1000 (effektiv jedoch nicht mehr als 1\,em der Schriftart).
% Sie können jede der beiden Zahlen auslassen, wenn Sie nicht wollen, dass
% das jeweilige Zeichen zu dieser Seite hervorragen sollte. Das abtrennende Komma jedoch
% dürfen Sie nicht auslassen.
%
%\paragraph{Optionen:}
%\begin{options}
%  \item[\key{name}] Sie können den Protrusionseinstellungen einen Namen zuweisen, sodass
%       Sie in der Lage sind, es aus einer anderen Liste zu laden.
%  \item[\key{load}] Sie können eine andere Liste laden (vorausgesetzt, dass Sie dieser zuvor
%       einen Namen zugewiesen haben) bevor die aktuelle Liste geladen wird, wodurch die Fonts die
%       Werte der geladenen Liste erben.
%      \par
%       Dadurch kann die Konfiguration beträchtlich erleichtert werden. Sie können
%       zum Beispiel eine Standardliste für eine Schriftarte erstllen; Einstellungen für andere
%       Formen oder Serien können diese Einstellungen laden, sie erweitern und überschreiben
%       (da der jeweils letzte Wert Vorrang hat). Font Einstellungen werden
%       rekursiv geladen.
%       Die folgenden Optionen werden alle geladenen Listen beeinflussen:
%\changes{v1.8}{2005/06/23}{add example for \texttt{factor} option}
%  \item[\key{factor}] Diese Option kann genutzt werden, um alle Protrusionsfaktoren
%       der Liste zu beeinflussen, was alle globalen \opt{factor} Einstellungen überschreibt (siehe
%       Abschnitt~\ref{sub:options-protrusion}). Wollen sie zum Beispiel, dass Fonts mit größeren Abmaßen
%       weniger hervorragen, könnten Sie die normalen Listen laden, allerdings
%       könnten Sie kleinere Faktoren darauf anwenden:
%\begin{verbatim}
%\SetProtrusion
%   [ factor   = 700
%     load     = cmr-T1 ]
%   { encoding = T1,
%     family   = cmr,
%     size     = large- }
%   { }
%\end{verbatim}
%  \item[\key{unit}] Standardmäßig sind die Protrusionsfaktoren relativ zur Breite
%       des jeweiligen Zeichens. Die |unit| Option kann genutzt werden, um dieses Verhalten
%       zu überschreiben, sodass \microtype\ diese Werte als Tausendstel der
%       angegeben Werte deutet. Gibt man z.B. die Anweisung `|unit=1em|' hätte dies den Effekt, dass
%       ein Wert von 50 nun darin resultieren würde, dass ein ein Zeichen um
%       5\% eines em des Fonts hervorragen würde (und somit die interne
%       Vermessung von \pdftex's \cmd\lpcode\ und \cmd\rpcode\ primitives simuliert).
%       Das normale Verhalten kann mittels |unit=character| wiederhergestellt werden.\footnote{
%          Die |unit| Option kann auch global an das Paket geleitet werden (siehe
%          Abschnitt~\ref{sub:options-protrusion}).
%          Allerdings werden alle vorliegenden Einstellungen unter der Annahme,
%          dass die Werte relativ zur Zeichenbreite sind, erstellt. Deshalb
%          sollten Sie es nur ändern wenn Sie sich sicher sind, dass
%          die Standardeinstellungen im Dokument nicht verwendet werden.}
%  \item[\key{preset}] Setzt die Protrusions Codes aller Zeichen auf die angegebenen
%       Werte (|={|\meta{left}|,|\meta{right}|}|), u.U. skaliert mit
%       einem |factor|. Eine |unit| Einstellung wird nur berücksichtigt, wenn sie
%       nicht |=character| ist.
%  \item[\key{inputenc}] Wählt eine Inputkodierung aus, die auf die Liste angewendet
%       werden soll, unabhängig von der Eingabekodierung des Dokuments selbst. Sie können jede
%       Kodierung angeben, die per \pkg{inputenc} geladen werden könnte,
%       also u.a. |ansinew|, |koi8-r|, |utf8|.
%  \item[\key{context}] Die Bandbreite der Liste kann auf einen gewissen Kontext limitiert
%       werden. Schauen Sie in Abschnitt~\ref{sec:context} für ein Anwendungsbeispiel nach.
%\end{options}
%
%
%\subsection{Fontexpansion}\label{sub:expansion}
%
%\Describe{Macro}{\SetExpansion}{?options,set of fonts,expansion settings}
% Standardmäßig können alle Zeichen eines Fonts um denselben Betrag gestrecht
% oder geschrumpft werden. Man kann aber auch die Expansionslimits für bestimmte
% einzelne Zeichen festlegen, wenn diese sensibler auf Deformation reagieren. Das ist der
% Zweck des \cs{SetExpansion} Kommandos. Beachten Sie, dass dies nur einen Effekt hat,
% wenn das Paket mit der Option \opt{selected} geladen wurde (siehe
% Abschnitt~\ref{sub:options-expansion}). Ansonsten werden die Expansionseinstellungen
% ignoriert~-- anders als die Optionen im optionalen ersten Argument, welche
% trotzdem ausgewertet werden.
%
% Falls das Paket mit der \opt{selected} Option geladen wurde und Einstellungen für einen Font
% nicht existieren, wird Fontexpansion gar nicht auf diesen Font angewendet.
% Sollte die außergewöhnliche Situation aufkommen, dass sie die ausgewählte Expansion
% generell verwenden wollen, aber dass alle Zeichen eines bestimmten Font (Sets)
% um denselben Betrag geschrumpft oder expandiert werden sollten, so müssen sie eine
% leere Liste für diese Fonts erstellen.
%
%\ifcmr\else\enlargethispage\baselineskip\fi ^^A layout
%\paragraph{Die Expansionseinstellungen}
% bestehen aus Paaren der Form \meta{character}\,|=|\,\meta{expansion factor}.
% Sie können eine Zahl für jedes Zeichen festlegen, die den Betrag bestimmt, um den
% ein Zeichen expandiert werden kann. Die Zahlen bezeichnen Tausendstel
% der vollen Expansion.
% Setzt man zum Beispiel den Expansionsfaktor des Zeichens `O' auf 500,
% wird dieses nur um die Hälfte des Betrages geschrumpft oder expandiert, um
% den die anderen Zeichen expandiert werden.
% Während der Standardwert für Character Protrusion auf 0 gesetzt ist -- sofern Sie
% keine Zeichen angegeben haben, wird auch keines hervorspringen ~-- ist der Standardwert
% für Expansion 1000, was bedeutet, dass alle Zeichen um denselben Betrag
% expandiert werden.
%
%\paragraph{Optionen:}
%\begin{options}
%  \item[\key{name}, \key{load}, \key{preset}, \key{inputenc}, \key{context}]
%       Analog zu \cs{SetProtrusion} kann dieses optionale Argument genutzt werden,
%       um einer Liste einen Namen zuzuweisen, eine andere Liste zu laden, alle Expansionsfaktoren
%       voreinzustellen, die Eingabekodierung festzulegen oder den Kontext der Liste
%       zu bestimmen (Expansionskontexte sind nur möglich mit \pdftex\
%       Version 1.40.4 oder neuer).
%\changes{v1.8}{2005/04/12}{add example of how to get rid of a widow

%  \item[\key{auto}, \key{stretch}, \key{shrink}, \key{step}]
%       Diese Schlüssel können genutzt werden um die globalen Einstellungen der Paketoptionen
%       zu überschreiben (siehe Abschnitt~\ref{sub:options-expansion}). Wenn Sie keine
%       der Optionen |stretch|, |shrink| und |step| angeben, wird ihr jeweiliger globaler
%       Wert genutzt (es findet also keine Berechnung statt).
%
%       Ein praktisches Beispiel: Nehmen wir an, wir haben einen Paragraphen, der eine
%       Witwe enthält, die man einfach hätte verhindern können, indem man den Font ein wenig
%       mehr geschrumpft hätte. In Verbindung mit der |context| Option (siehe Abschnitt~\ref{sec:context}
%       für weitere Details) könnte man mit diesem speziellen Paragraphen mehr Expansion erlauben:
%\begin{verbatim}[gobble=2]
% \SetExpansion
%    [ context = sloppy,
%      stretch = 30,
%      shrink  = 60,
%      step    =  5  ]
%    { encoding = {OT1,T1,TS1} }
%    { }
% % ... END PREAMBLE
% {\microtypecontext{expansion=sloppy}%
%  Dieser Paragraph enthält eine `unnötige' Witwe.}
%\end{verbatim}
%       Diese Methode, Kontext anzuwenden um vorübergehend verschiedene
%       Expansionsparameter zu setzen funktioniert nur mit \pdftex\ 1.40.4 oder neuer
%       (für ältere Versionen wird ein schmutziger Trick in
%       Abschnitt~\ref{ssec:font-setup} auf Seite~\pageref{exp-hack} beschrieben). Bedenken Sie auch,
%       dass \pdftex\ die Nutzung von Fonts mit verschiedenen Expansionslimits oder -stufen
%       (sogar für verschiedene Fonts) innerhalb eines Paragraphs verbietet, weswegen
%       der saloppe Kontext benutzt werden muss, um Paragraphen zu komplettieren.
%  \item[\key{factor}]
%       Diese Option stelle eine andere Methode bereit, um Expansionseinstellungen für
%       bestimmte Fonts zu verändern, arbeitet aber um die eben beschriebenen Restriktionen herum. Die
%       |factor| Option beeinflusst die Expansionsfaktoren aller Zeichen (in
%       Kontrast zur allgemeinen Streckbarkeit) des Fonts. Wollten sie z.B. die
%       kursive Form weniger expandieren lassen, würden sie vereinbaren:
%\begin{verbatim}
%\SetExpansion
%   [ factor   = 500 ]
%   { encoding = *,
%     shape    = it }
%   { }
%\end{verbatim}
%       Die |factor| Option kann nur genutzt werden, um die Streckbarkeit der Zeichen 
%       zu \emph{verringern}, weshalb sie nur Werte kleiner als 1000 erhalten darf.
%       Außerdem kann sie nur für einzelne Fonts oder Font Sets genutzt werden;
%       die Option global in den Paketoptionen zu setzen macht wenig Sinn --
%       dafür nutzt man die Optionen \opt{stretch} und
%       \opt{shrink} des Pakets.
%\end{options}
%
%
%\subsection{Tracking}\label{sub:tracking}
%\Describe{Macro}{\SetTracking}{?options,set of fonts,tracking amount}
% Eine bedeutende typographische Technik -- welche lange in \TeX\ fehlte --
% ist die Anpassung des Trackings, sprich die uniforme Addition oder Subtraktion
% von Sperrsatz zu/von allen Zeichen eines Fonts. Zum Beispiel ist es ein 
% normal üblicher, typographischer Brauch, komplett in Kapitälchen
% (wie in diesem Dokument) ein wenig zu sperren. Die Lesbarkeit kann auch verbessert
% werden, indem man das Tracking von kleinerer Typen minimal erhöht und das größerer
% Typen minimal erhöht.\footnote{
%     Für Fonts mit vollem Funktionsumfang wie Computer Modern ist das für gewöhnlich
%     nicht nötig, da sie in optischen Größen kommen und das Tracking der Kapitälchen
%     bereits angepasst ist.}
% Das \cs{SetTracking} Kommando erlaubt, die Menge des Trackings für verschiedene
% Fonts oder Font Sets zu setzen. Es wird vom \cs{textls} Kommando ausgewertet,
% welches genutzt werden kann, um kleinere Textpassagen zu sperren (siehe
% Abschnitt~\ref{sec:lettersp}).
%
%\paragraph{Die Menge des Tracking}
% wird festgelegt in Tausendsteln von 1\,em (oder der gegebenen Einheit); negative Werte
% sind ebenfalls erlaubt.
%
%\paragraph{Optionen:}
%\begin{options}
%  \item[\key{name}, \key{unit}, \key{context}]
%       Diese Optionen dienen derselben Funktionalität wie bei den vorigen
%       Konfigurationskommandos. Die Einheit kann jegliche Dimension annehmen, 
%       der Standard beträgt 1\,em.
%  \item[\key{spacing}]
%       Werden die \emph{Zeichen}zwischenräume verändert, müssen auch die \emph{Wort}zwischenräume
%       vielleicht angepasst werden. Diese Option erwartet drei Zahlen für Wortzwischenraum,
%       bzw. Streckung und Schrumpfung, welche in Tausendsteln eines 1\,em
%       angegeben werden (oder in der aktuellen Einheit (\texttt{unit})). Folgt 
%       einem Wert ein Asterisk, so zeigt es an, dass Tausendstel der jeweiligen
%       Fontdimension zu dieser hinzuaddiert werden. Zum Beispiel werden durch
%\begin{verbatim}
%\SetTracking[ spacing = {25*,166, } ]{ encoding = *, shape = sc }{ 25 }
%\end{verbatim}
%       die Wortzwischenräume um 2.5\% erhöht, die Streckung wird auf einen Betrag
%       von 0.166\,em gesetzt, an den Schrumpf-Einstellungen wird nichts geändert. Falls
%       sie die \texttt{spacing} Option nicht angeben, wird der Wortzwischenraum
%       über die aktuelle Größe der Sperrsatzabstände skaliert (wie in obigem Beispiel),
%       wobei stretch und shrink unberührt bleiben.
%  \item[\key{outer spacing}]
%       Falls ein Wortzwischenraum direkt auf Sperrsatz folgt (oder umgekehrt),
%       wird er standardmäßig gleich den Zwischenräumen im gesperrten Text behandelt.
%       Mit dieser Option, welche dieselben Werte wie \texttt{spacing} akzeptiert, 
%       kann sie unabhängig eingestellt werden.
%  \item[\key{outer kerning}]
%       Falls andererseits kein Wortzwischenraum folgt oder vorgeht, können Sie
%       immer noch die ersten und letzten Buchstaben von angrenzenden Buchstaben 
%       abtrennen. Diese Option erwartet durch Komma abgretrennte Kerning Beträge 
%       für die linke und rechte Seite, in Tausendsteln eines 1\,em (oder der aktuellen
%       \texttt{unit}). Folgt einem Wert ein Asterisk, bezeichnet dies Tausendstel 
%       der aktuellen Abstandsgröße des Sperrsatzes. Ein einzelner Asterisk bedeutet
%       `|500*|'; das ist ebenso der Standard, sprich die Summe des äußeren Kerns beträgt
%       standardmäßig soviel wie die aktuelle Größe der Abstände des Sperrsatzes. Um kerning auf
%       beiden Seiten zu entfernen, verwendet man `|outer kerning={0,0}|'.
%  \item[\key{no ligatures}]
%       Soweit \pdftex\ betroffen ist, werden Ligaturen in gesperrten Fonts 
%       wie gewöhnlich konstruiert, was angebracht sein kann, wenn das Tracking
%       um einen kleinen Betrag geändert wird. Für größere Abstände andererseits
%       hätte der normale Abstand zwischen Zeichen innerhalb Ligaturen
%       enttäsuchende \textls[150]{E\lslig{ff}ekte}.
%       Dieser Schlüssel erwartet eine per Komma abgetrennte Liste von Zeichen, für welche
%       die Ligaturen abgeschaltet werden sollen; nur das Zeichen, mit welchem die Ligatur
%       beginnt, muss angegeben werden.
%       Wird der Schlüssel ohne Wert angegeben, so werden \emph{alle} Ligaturen des Fonts
%       abgeschaltet. Das wird jedoch nicht empfohlen, da es ebenso mit sich bringt, dass
%       Kerning ausgeschaltet wird.\footnote{
%         Die untrennbare Verbindung von Ligaturen und Kernen ist eine Begrenzung von
%         \TeX\, die nicht vor der Einführung \luatex beseitigt wird.}
%       Die Standardeinstellungen stellen Ligaturen nur für das Zeichen `|f|' ab,
%       sprich, `ff', `fi', ffi', etc.\footnote{
%         Mit \pdftex\ Versions vor 1.40.4 sind \emph{alle} Ligaturen und
%         somit jegliches Kerning abgeschaltet. Es wird deshalb empfohlen, wenigstens
%         Version 1.40.4 zu nutzen.}
%       In außergewöhnlichen Situationen könenn Sie manuell Ligaturen aufbrechen, indem
%       sie `|{\kern0pt}|' bzw. \pkg{babel}s \verb="|=
%       Kürzel verwenden, oder aber die Ligaturen schützen, indem Sie sie in \cs{lslig} einschließen (siehe

%
%\Describe{Macro}{\SetExtraKerning}{?options,set of fonts,kerning settings}
% Mit diesem Befehl können sie das zusätzliche Kerning feinabstimmen. Im Vergleich zu
% herkömmlichem Kerning, welches immer mit einem \emph{Paar} von Zeichen assoziiert
% wird, und Tracking, welches den Zwischenraum zwischen \emph{allen}
% Zeichen eines Fonts angibt, bezieht sich zusätzliches Kerning nur auf einzelne Zeichen,
% soll heißen, immer wenn ein bestimmtes Zeichen im Text auftaucht, wird das angegebene
% Kerning eingefügt, unabhängig davon, welche Zeichen vorgehen oder folgen.
%
% Ich sollte nicht versäumen zu sagen, dass es eine Limitierung zusätzlichen Kernings gibt:
% Wörter, die solch einem Kern\emph{direkt folgen} (nicht von einem Leerzeichen getrennt),
% werden nicht mit Bindestrich versehen, solang man die Trennpunkte nicht selbst einstellt, 
% z.B. für Kerning nach dem Apostroph `|l'apos\-trophe|'. Diese Restriktion von \pdftex\
% wird hoffentlich bald abgeschafft.

%\subsection{Wortzwischenräume}\label{sub:spacing}
%
%\Describe{Macro}{\SetExtraSpacing}{?Optionen,Font Set,Spacing Einstellungen}
% Dieser Befehl erlaubt Ihnen, die Wortzwischenräume fein abzustimmen (auch bekannt als
% glue). Eine vorausgehende Bemerkung darüber, was ein `Zwischenraum' ist, könnte angebracht sein: zwischen zwei
% Wörtern fügt \TeX\ sogenannten glue ein, welcher von drei Parametern charakterisiert wird
% -- der normale Abstand zwischen zwei Wörtern, der maximale Abstand, der dem angefügt
% werden darf, und das Maximum welches davon subtrahiert werden kann.
% Die letzteren beiden Parameter wirken wann immer \TeX\ versucht, einen Paragraphen
% in Zeilen zu zerlegen und dabei scheitert; es kann die Räume zwischen Wörtern strecken
% oder schrumpfen. Diese drei Parameter sind spezifisch für jeden Font.
%
% Obendrein beherrscht \TeX\ das Konzept von `space factors'.
% Sie können genutzt werden, um die Räume zwischen bestimmten Zeichen, besonders
% den Satzzeichen zu vergrößern. Falls \pdftex zusätzliche Zwischenräume
% in Betrieb sind, werden space factors ignoriert, da es als Erweiterung
% zu space factors mit viel präziserer Kontrolle betrachtet werden kann.
%
%\paragraph{Einstellungen an den Zwischenräumen}
% werden als Paare der Form \meta{Zeichen}\,|=|\,\meta{Zwischenraum Faktoren} deklariert, wobei
% letztere aus drei Zahlen bestehen: zuerst der zusätzliche Kern, der nach diesem Zeichen
% angefügt wird, wenn es vor einem Wortzwischenraum vorkommt, 2. der zusätzliche Streckungsbetrag
% und zuletzt der zusätzliche Schrumpfbetrag. Alle Werte können auch negativ sein,
% wodurch die Dimensionen verkleinert werden. Nicht alle Werte müssen angegeben werden,
% die Einstellungen müssen jedoch zwei abtrennende Kommas beinhalten.
%
%\paragraph{Optionen:}
%\begin{options}
%  \item[\key{name}, \key{load}, \key{factor}, \key{preset}, \key{inputenc}, \key{context}]
%       Diese Optionen dienen der gleichen Funktionalität wie in den vorigen
%       Konfigurationsbefehlen.
%  \item[\key{unit}] Sie können die Einheit wählen, in der die angegebenen Zahlen
%       gemessen werden. Mögliche Werte sind: |character|, eine \meta{Dimension} und
%       zusätzlich |space|. Letztere Einstellung misst die Werte in Tausendsteln der
%       jeweiligen Dimension, die vom Font eingestellt ist. Standardmäßig wird die Einheit
%       in Zwischenraumdimensionen gemessen. Mit folgenden (unsinnigen) Einstellungen z.B.:
%\begin{verbatim}
%\SetExtraSpacing
%   [ unit = space  ] % default
%   { font = */*/*/*/* }
%   {
%       .  = {1000,1000,1000},
%   }
%\end{verbatim}
%       würde der Raum nach einem Punkt verdoppelt (streng genommen:
%       2\,\texttimes\ \fontdim2),ebenso
%       die Schrumpfbeträge der Wortzwischenräume (\fontdim3 und~4). Umgekehrt
%       würde man, so alle drei Werte auf \textminus1000 setzt, das Leerzeichen
%       nach dem betreffenden Zeichen komplett aufheben.
%\end{options}
%
%
%\subsection{Zeichenvererbung}\label{sub:inherit}
%
% \Describe{Macro}{\DeclareCharacterInheritance}
%                 {?Features,Font Set,Vererbungslisten}
% In den meisten Fällen sollten akzentuierte Zeichen die Einstellungen ihres
% Ursprungszeichens erben. Zum Beispiel sollten vermutlich alle der Zeichen \`A, \'A, \^A,
% \~A, \"A, \r{A} und \u{A} um denselben (absoluten) Betrag hervorragen wie der
% Buchstabe A. Nutzt man den Befehl \cs{DeclareCharacterInheritance},
% so kann man Klassen von Zeichen benennen, wodurch man nur das betreffende
% Grundzeichen einstellen muss. Mit dem zusätzlichen Argument, welches eine per
% Komma abgetrennte Liste von Features enthalten kann, können Sie die Reichweite
% der Liste beschränken. Zusätzlich dazu akzeptiert es den |inputenc| Schlüssel, um die Eingabekodierung
% für diese Liste einzustellen. Das Font Set kann wie üblich eingestellt werden.
% Die einzige Ausnahme hierbei ist, dass exakt eine Kodierung gewählt werden muss. Die Vererbungslisten
% werden als Paare der Form \meta{base character}\,|=|\,\meta{Liste der erbenden
% Zeichen} deklariert. Solange Sie keine abweichende Kodierung oder einen sehr eigenartig
% geformten Font verwenden, sollte es keinen Grund geben, die standardmäßigen Vererbungseinstellungen
% zu ändern.
%
%\bigskip\noindent
% In der Hauptkonfigurationsdatei \file{microtype.cfg} und den anderen
% font-spezifischen Konfigurationsdateien können Sie Beispiele zu all
% diesen Befehlen finden.
%
%
%\subsection{Konfigurationsdateien}\label{sub:config-file}
%
% Die Standardkonfiguration beinhaltet Vererbungseinstellungen, Deklarationen von
% Font Sets und alias Fonts sowie generische Hervorragung, Expansion, Spacing und
% Kerning Einstellungen, und wird aus der Datei \file{microtype.cfg} geladen. Sie können
% diese Datei mit eigenen Einstellungen erweitern (oder eine andere Konfigurationsdatei
% mit der `\opt{config}' Option laden, siehe Abschnitt~\ref{sub:options-misc}).
%
% Wenn Sie den Weg einschlagen, neue Einstellungen für eine Fontfamilie zu treffen, sollten Sie
% diese in eine separate Datei stecken, deren Name `|mt-|\meta{Fontfamilie}|.cfg|' 
% (z.B. `\file{mt-cmr.cfg}') lauten muss, und welche alle Befehle enthalten muss,
% die in diesem Abschnitt~\ref{sec:fine-tuning} beschrieben. Diese Dateien werden
% automatisch geladen, wenn sie die betreffenden Fonts tatsächlich nutzen.
% Das Paket kommt mit mit Konfigurationsdateien für eine Reihe von Fontfamilien;
% Tabelle~\ref{tab:fonts} enthält sie alle.

%\DescribeMacro{\DeclareMicrotypeVariants*}
% Auf seiner Suche nach einer Konfigurationsdatei versucht das Paket auch,

% des Basisfonts hindeuten könnten (vergleiche Karl Berrys \cite{fontname}). Das erlaubt z.B.,
% Einstellungen für z.B. die Fonts |padx| (Experten Set), |padj| (altertümliche Numerale)
% und |pad| (einfach) in der selben Datei \file{mt-pad.cfg} vorzunehmen.
% Der Befehl erwartet eine durch Komma abgetrennte Liste von Suffixen für Varianten. Die Version
% mit Stern hängt die Suffixe der existierenden Liste an. Die Standard-Deklaration
% in \file{microtype.cfg} lautet:
%\begin{verbatim}
%\DeclareMicrotypeVariants{x,j,w,a,d,0,1}
%\end{verbatim}
%
%\medskip
%\Describe{Macro}{\DeclareMicrotypeAlias}{Fontname,alias Font}
% Dieser Befehle kann für Fonts genutzt werden, die sich sehr ähnlich
% oder gar gleich sind (falls sie sich zum Beispiel nicht an das Berry Namensgebungsschema beim
% Installieren der Fonts hielten). Ein Beispiel wären die Latin Modern Fonts, welche
% von Computer Modern abgeleitet sind, sodass es nicht notwendig ist, neue Einstellungen
% für diese vorzunehmen -- man könnte sagen:
%\begin{verbatim}
%\DeclareMicrotypeAlias{lmr}{cmr}

%\section{Kontext-sensitive Einstellungen}\label{sec:context}
%
% Das \microtype\ -Paket erlaubt zudem verschiedene Mikro-typografische

% verwenden.
% Dies eröffnet unendlich viele Möglichkeiten der Feinabstimmungen für das Aussehen 
% des Dokuments.
%
%\medskip
%\Describe{Macro}{\microtypecontext}{context assignments}
% Dieser Befehl kann überall im Dokument (auch in der Präambel) verwendet werden, 
% um den Mikro-typografischen Zusammenhang in der aktuellen Gruppe zu ändern. 
% Zu jeder Funktion (\key{protrusion}, \key{expansion}, \key{tracking},

%\end{verbatim}
%\ifcmr\else\enlargethispage{2\baselineskip}\fi ^^A layout
% um damit den Kontext im Fussnoten-Befehl zu ändern. Dieser Befehl 
% unterscheidet sich zwischen den verscheidenen Klassen. Für die Basisklassen z.B, % \pkg{article}, wäre es:
%\begin{verbatim}
%\newcommand*\new@makefnmark{\hbox{\@textsuperscript{\normalfont
%   \microtypecontext{protrusion=footnote}\@thefnmark}}}
%\renewcommand*\@footnotemark{%
%   \leavevmode \ifhmode\edef\@x@sf{\the\spacefactor}\nobreak\fi
%   \new@makefnmark \ifhmode\spacefactor\@x@sf\fi \relax}
%\end{verbatim}
% Für die \pkg{memoir} Klasse, müssten Sie zusätzlich die automatische Erkennung 
% mehrerer Fussnoten deaktivieren, welches ein hervorheben des Fussnotentextes 
% verhindert.
%\begin{verbatim}
%\renewcommand*\@makefnmark{\hbox{\@textsuperscript{\normalfont
%   \microtypecontext{protrusion=footnote}\@thefnmark}}}
%\let\m@mmf@prepare\relax
%\let\m@mmf@check\relax
%\end{verbatim}
% ^^A For other classes, the command would have to be changed in a similar way.
%
%\medskip\noindent
% Eine weitere Möglichkeit wäre es den Kontext für eine sprachabhängige Einstellung 
% zu verwenden. 
% Zum Beispiel, wenn Sie einen Text auf Französisch schreiben, können Sie
%\begin{verbatim}
%\microtypecontext{kerning=french}
%\end{verbatim}
% in der Präampel hinzufügen. Das hätte den Effekt, dass die 
% Abstandseinstellungen des französischen Kontextes, für das Dokument übernommen würden. Sollten Teile des Dokuments in Englisch sein, könnten Sie schreiben
%\begin{verbatim}
%\textmicrotypecontext{kerning=}{English text!}
%\end{verbatim}
% um den Kontext zurückzusetzen, so dass die Interpunktion in diesen 
% Teilen kein extra Zeichenabstand erhalten.
%
% Anstatt diese Befehle manuell zu Ihrem Dokument hinzuzufügen, können Sie  
% \microtype\	auch mit der \opt {Babel}-Funktion laden 
% (siehe Abteilung~\ref{sub:options-misc}).
% Die aktuelle Sprache wird dann automatisch erkannt und der Kontext
% dementsprechend angepasst.
%
%\medskip
%\Describe{Macro}{\DeclareMicrotypeBabelHook}
%                {list of \pkg{babel} languages,context list}
% Natürlich kennt \microtype\ nicht jede typografische Besonderheit, jeder einzelen 
% Sprache.
% Dieser Befehl ist ein Mittel, um zu lehren, wie man den Kontext anpassen 
% kann, wenn eine bestimmte Sprache ausgewählt ist. Die Hauptkonfigurationsdatei
% enthält unter anderen die folgende Deklaration:
%\begin{verbatim}
%\DeclareMicrotypeBabelHook
%   {french,francais,acadian,canadien}
%   {kerning=french, spacing=}
%\end{verbatim}
% Folglich, wann immer Sie auf französische Sprache umschalten, wird die 
% Abstandseinstellung im Kontext auf `|französisch|' geändert und der 
% Abstandskontext zurüchgesetzt.
% Dieser Effekt greift nur dann, wenn das Paket mit der \opt {babel} Option geladen % wurde. Derzeit unterstützt \microtype\ französische, türkische und englische 
% Buchstabenabstände (auch bekannt als \cmd\nonfrenchspacing). Für unbekannte 
% Sprachen werden alle Kontexte zurückgesetzt.

%
%\section{Erneute Betrachtung der Funktion Letterspacing}\label{sec:lettersp}
%
%\Describe{Macro}{\textls}{?amount,general text}
%\DescribeMacro{\textls*}
%\DescribeMacro{\lsstyle}
% Während die \opt{tracking} Funktion, die im Abschnitt~\ref{sub:tracking} 
% beschrieben wurde, für Sätze von Schriftarten gilt, können sie letterspace 
% benutzen um kürzere Stücke des Textes zu erzeugen, unabhängig von der Schriftart 
% in dem sich der Schriftsatz befindet.\footnote{
%   Letterspacing sollte vorsichtig verwendet werden, insbesondere der 
%		Zeichenabstand der Kleinbuchstaben wird mit Abscheu von einigen Typpgrafen 
% 	betrachtet. Falls sie wissen was sie tun, sollten Sie vielleicht kleine Kapitel % 	oder oder alle Kapitel nutzen. Eine andere Eigenschaft kann zur Betonung in 
% 	Texten von Schriftarten verwendet werden.}
% Für solche Ad-hoc-Zeichenabstände, bestizt \microtype\ zwei Befehle, (unabhängig 
% davon, ob die |tracking| Option aktiviert ist) die auf die gleiche Weise
% verwendet werden können wie die \LaTeX-Befehle: \cs{textls} -- welches auch im 
% Mathemodus funktioniert --  erwartet der Text im notwendigen Argument, während 
% \cs{lsstyle} `letterspacing' für alle nachfolgenden Schriften bis zum Ende der 
% aktuellen Gruppe aktiviert wird. Die Favoriten-Version von \cs{textls} fügt keine % zusätzlichen Buchstabenabstände, vor oder nachdem Text ein, was für z.B 
% Absatztitel nützlich sein  kann.
% Standardmäßig wird jedes Zeichen mit 100/1000 \,em \,= \,0.1 \,em von einander 
% getrennt, dieser Betrag kann im optionalen Argument von \cs {textls}, durch 
% Verwendung des \cs {SetTracking} Befehl oder global über die \opt {letterspace} 
% Paketoption, geändert werden, mit abnehmender Signifikanz in dieser Reihenfolge.
%
%\medskip
%\Describe{Macro}{\lslig}{ligature}
% Seitdem die Befehle \cs{textls} und \cs{lsstyle} auch die
% `\texttt{no ligatures}'-Schlüssel für die entsprechenden Schriftarten auswerten,
% brauchen Sie sich keine Gedanken mehr über das Schützen oder Trennen von Liganten % in den meisten Schriftarten zu machen. Jedoch, in bestimmten Situationen, kann es % zu einem Konflikt der Liganten, welche mit den gleichen Buchstaben beginnen, 
% kommen, wobei einige von diesen verhindert werden sollten, während das bei 
% anderen nicht geschehen soll. Beim letterspacing von Texten mit Textschriftsatz 
% in Frakturschriftarten, sollen zum Beispiel, die Liganten 'ch', 'ck', 'tz' und 
% 'sz' ~(`\textfrak {sz}') niemals getrennt werden, normalerweise sieht man auch 
% 'St.' ~(`\textfrak {St.}') Liganten im letterspacing-Text. Darüber hinaus 
% realisiert  das \pkg{yfonts} Paket das kurze ~s~(`\textfrak{s:}') als den
% Liganten~`|s:|' andererseits, wenn der `ct'~Ligant und die anderen `lang~s' 
% Liganten in Frakturschriftarten gefunden werden, unterdrückt werden. 
% Es gibt zwei Wege dieses Problem zu lösen: Entweder deaktivieren Sie nicht die
% "`| s | und/ oder | c |" Ligaturen und 
% trennen diejenigen, die getrennt werden müssen durch das Einfügen von 
% `|{\kern0pt}|' oder  \pkg{babel}'s Abkürzung oder deaktivieren Sie diese 
% und schützen jene Liganten welche geschützt werden müssen, durch umschließen mit % dem \cs{lslig} Befehl. Damit liefern folgende Lösungen das gleiche Ergebnis
% (nämlich, `\textfrak{\lsstyle Aus:s{\kern0pt}ichts:los{\kern0pt}igkeit}').
%
%\begin{verbatim}[morekeywords={[0]{\kern}}]
%\SetTracking[no ligatures={f}]{encoding = LY, family = yfrak}{100}
%\textfrak{\lsstyle Aus:s{\kern0pt}ichts:los{\kern0pt}igkeit}
%\end{verbatim}
%\begin{verbatim}
%\SetTracking[no ligatures={f,s,c}]{encoding = LY, family = yfrak}{100}
%\textfrak{\lsstyle Au\lslig{s:}si\lslig{ch}t\lslig{s:}losigkeit}
%\end{verbatim}
%
%\bigskip\noindent
%\DescribePackage{letterspace} 
% Diese drei Befehle (mitsamt der \opt{letterspace} -Option, beschrieben in
% Abschnitt~\ref{sub:option-tracking}) sind auch in dem alternativen
% \letterspace\ Paket enthalten, welches ansich eine sehr stark abgespeckte Version % von \microtype\ ist, das eine Unterstützung für alle anderen Erweiterungen 
% weglässt (zudem wurden die Möglichkeiten des \cs{SetTracking} Befehls weggelassen % und alle `|f|' Liganten werden deaktiviert, innere und äußere Abstände und der 
% äußere  Buchstabenabstand wurden auf ihre Standartwerte zurückgesetzt, so wie in 
% Abschnitt~\ref{sub:tracking} beschrieben). Wenn Sie es bevorzugen auf
% \microtype's Besonderheiten zu verzichten, können Sie stattdesen das 
% \letterspace\ Paket laden. Beide Pakete können nicht zur gleichen Zeit benutzt 
% werden.
%
% Im Gegensatz zu \microtype, welches \LaTeX\ verlangt, arbeitet das \letterspace\  
% Paket auch mit \pkg{eplain} oder auch nur mit \pkg{miniltx}: beim Gebrauch von
% \pkg{eplain}, laden Sie das Paket mit \cmd\usepackage\ innerhalb  
% \cmd\beginpackages~\dots\ \cmd\endpackages\ Umgebung, für \pkg{miniltx}
% (welches die Paketoptionen nicht unterstützt) einfach mit \cmd\input\ 
% \file{letterspace.sty} laden.
%
%
%\section{Deaktivieren von Ligaturen(Bindungen)}\label{sec:disable-ligatures}
%
%\Describe{Macro}{\DisableLigatures}{?characters,set of fonts}
% Beim vollständigen Deaktivieren aller Liganten einer Schriftart (welches auch 
% Kerning für diese Schriftart ausschaltet, senkt \textit{lowers} absichtlich die 
% mikro-typografische Qualität des Textes, anstatt diese zu erhöhen, dies ist 
% speziell für Schreibmaschine-Schriftarten nützlich, so dass, z.B. in einer &lt;T1&gt; 
% kodierten Schriftart, `|\texttt{--}|' natürlich als  `|--|', nicht als 
% `\texttt{--}'gedruckt wird. \cs{DisableLigatures} kann dazu verwendet werden, um % auf gewöhnlichem Weg, eine Reihe von Schriftarten zu spezifizieren, für welche 
% Liganten deaktiviert sein sollen, z.B für die Schriebmaschinenschrift kodiert in &lt;T1&gt;:
%\begin{verbatim}
%\DisableLigatures{encoding = T1, family = tt* }
%\end{verbatim}
% Es ist auch möglich nur ganz bestimmt Liganten zu deaktivieren. Das optionale 
% Argument, kann eine durch Komma getrennte Liste von Zeichen enthalten, für die 
% der Ligantenmechanismus unterbunden werden soll:
%\begin{verbatim}
%\DisableLigatures[?,!]{encoding = T1} % "\ifx\tagcode\undefined\else ^^A
%           \normalfont\color{thegrey}inhibit ?` and !`, but not fi, --, &gt;&gt;, etc.\fi"
%\end{verbatim}
% Dabei ist der Buchstabe, mit dem der Ligant beginnt von Bedeutung. Dieser Befehl 
% kann nur in der Präampel verwendet werden und auch nur einmal. Der Befehl 
% fortert \pdftex\ 1.30 oder eine aktuellere Version.
%
%
%\section{Hinweise und Warnungen}\label{sec:caveats}
%
%\paragraph{Verwenden Sie Einstellungen, die zu Ihrer Schriftart passen.}
% Obwohl die Standardeinstellungen akzeptable Ergebnisse für die meisten Schriften 
% liefern sollten, kann es sein das die spezielle Schriftart, welche Sie gerade 
% verwenden, verschiedene Schriftformen hat, so dass mehr oder weniger Hervorhebung 
% oder Vergrößerungen erforderlich sind. Insbesondere kursive Schriftformen 
% können sich deutlich in unterschiedlichen Schriftarten unterscheiden, deshalb
% habe Ich mich dageben entscheiden Standarthervorhebungseinstellungen für diese 
% anzubieten. Die Datei \file{test-microtype.tex} kann eine Hilfe, beim anpassen 
% der Hervorhebungseinstellungen für eine Schriftart sein.
%
%\paragraph{Verwenden Sie keinen zu großen Wert für die Vergrößerung.}
% Font-expansion (Schriftartenvergrößerung) ist eine Funktion, welche die 
% typographische Qualität des Dokuments verbessern soll, indem sie eine 
% gleichmäßige Graustufe des Textblocks erzeugt (und potenziell die Verringerung 
% der Zahl der erforderlichen Silbentrennungen).
% Wenn die Erweiterung oder Verkleinerung einer Schrift zu groß 
% oder zu klein wird, so wird der Effekt ins Gegenteil gewandelt. Die Vergrößerung 
% der Schriftarten um mehr als 2\%, d.h. der Wert der Einstellung \opt{Strecken}
% größer als 20 ist, erfordert ein geschultes Auge.
% Wenn Sie das Glück haben und im Besitz von mehreren Kopien einer 
% multiplen Master-Schriftart sind, können Sie die Vergrößerungsgrenze bis 
% auf 4\% erhöhen.

%\changes{v2.0}{2006/12/13}{Hinweis für Web-Dokumente im Hinblick auf ältere \pdftex\ Versionen}
%\paragraph{Verwenden Sie keine Schriftartvergrößerung für Web-Documente (mit 
% älteren \pdftex\ Versionen).}
% Mit \pdftex\ Versionen die älter als die 1.40 Version sind, wird jede vergrößerte % Kopie der Schriftart in der &lt;PDF&gt; Datei eingebettet, folglich kann die 
% Dateigröße stark zunehmen (abhängig von Vergrößerungsgrenze und -schritt). 
% Deshalb, für die Zuvorkommenheit und für Sparsamkeit der Bandbreite, aktivieren 
% Sie nicht die Schriftartenvergrößerung, beim Erstellen von Datein die 
% elektronisch verteilt werden. Mit \pdftex\ 1.40, 
% welches eine andere Technik der Vergrößerung nutzt, kann die Erhöhung der 
% Dateigröße vernachlässigt werden.

%\changes{v1.9}{2005/07/10}{Hinzufügen von Hinweisen in \texttt{verbatim} Umgebungen}
%\todo{introduce option to patch \texttt{verbatim}} ^^A for Karl
%\paragraph{Möglicherweise möchten Sie die Hervorhebungen in der \texttt{verbatim} % Umgebung deaktivieren.}
% Wie Sie bereits wissen, wird \microtype\ standartmäßig die Zeichenhervorhebung in % allen Schriftarten aktiviert, die im Schriftartenset `|alltext|' enthalten sind. % Das schließt auch die Schreibmaschinenschrift mit ein. Obwohl es wirklich Sinn 
% macht, die Schreibmaschine-Schriftart hervorzuheben, wenn Sie im laufenden Text 
% erscheint (wie, zum Beispiel, in diesem Handbuch), ist dies wahrscheinlich nicht 
% wünschenswert innerhalb der |verbatim| Umgebung. Jedoch hat
% \microtype\ kein Wissen über den Kontext, in dem eine Schriftart steht, dies wird % allein durch die Bestimmung der Attribute entschieden. 
% Deshalb müssen Sie sich um die Deaktivierung der Hervorhebung in der |verbatim| 
% Umgebung, selbst kümmern (d.h wenn Sie Hervorhebungen in der
% Schreibmaschinenschrift, nicht durch auswählen eines anderen Schriftsatzes 
% insgesamt deaktivieren  wollen). Obwohl der \cs{microtypesetup} Befehl natürlich % für Fälle wie diesen entwickelt wurde, könnten Sie es 
% anstrengend finden ihn jedesmal zu wiederholen, wenn Sie ihn in der |verbatim| 
% Umgebung öfters nutzen. Die folgende Zeile, die der Präampel hinzugefügt wird, 
% hätte den selben Effekt:
%\changes{v2.3e}{2009/07/21}{suggest to patch \cmd\@verbatim\ instead of \cmd\verbatim}
%\begin{verbatim}
%\g@addto@macro\@verbatim{\microtypesetup{activate=false}}
%\end{verbatim}
% Falls sie das \pkg{fancyvrb} oder das \pkg{listings} Paket verwenden, ist dies 
% nicht notwenig, da diese so konzipiert sind, das Sie in der entsprechenden 
% Umgebung, die Hervorhebung in jedem Fall hemmen.
%
%\changes{v1.9e}{2006/07/10}{add hint about unknown encodings}
%\paragraph{Einstellungen für Griechisch/Thailändisch/Amerikanisch usw. Kodierungen 
% sind bis jetzt noch nicht inbegriffen.}
% Die Standartsätze von Schriftarten, für welche die mikro-typrografischen 
% Funktionen aktiviert werden (siehe Tabelle~\ref{tab:predefined-font-sets}), 
% enthalten nur die Kodierungen für die auch  Konfigurationen existieren. Deshalb, % wenn Sie eine andere Kodierung verwenden (z.B. &lt;LGR&gt;, &lt;T2B&gt;, etc.), wird 
% \microtype\ nicht auf diese Schriftarten anwendbar sein. Sie müssen einen neuen 
% Schriftsatz, einschließlich der Kodierung, definieren und aktivieren um Sie 
% benutzen zu können(weitere Details, siehe 
% Abschnitt~\ref{sec:font-sets}). Spätestens für die Hervorhebungen müssten Sie
% Einstellungen für die Schriftarten die in Frage kommen erstellen (siehe 
% Abschnitt~\ref{sub:protrusion}). 
% Selbstverständlich sind Beiträge für diese Art von Kodierung mehr als willkommen.
%
%\paragraph{Nehmen Sie nur dann Kerning-Anpassungen vor, wenn es üblich in der typografischen Tradition der Sprache ist.}
% Im Gegensatz zu Hervorhebung und der Vergrößerung, trägt zusätzliche Kerning 
% nicht unbedingt zur Verbesserung der mikro-typographische Qualität des Dokuments % bei. Sie sollten das zusätzliche Kerning nur aktivieren, wenn Sie ein Dokument in % einer Sprache schreiben, dessen typografische Tradition ein solches Kerning 
% garantiert. Wenn Sie zum Beispiel einen englischen Text schreiben, würden die 
% Leser durch zusätzliche Leerzeichen vor dem Satzzeichen verwirrt werden.

% Die Umsetzung dieser Eigenschaft in \pdftex\ ist nicht vollständig und kann zu 
% den positiven Auswirkungen, auf die typographische Qualität, die Sie eventuell 
% erwarten, nicht beitragen. In bestimmten Situationen kann es sogar zu 
% unerwünschten Nebenwirkungen kommen.
% Deshalb, sollte die \opt {Abstand}option nicht blind gewählt werden. Es wird

%\paragraph{Kompatibilität und Interaktion mit anderen Paketen:}
% Das \microtype\ -Paket sollte sehr gut mit anderen

% das Leben nicht perfekt ist, sind Probleme zu erwarten. Momentan sind folgende 
% Probleme bekannt:
%\begin{itemize}
%  \item Wenn Sie 8-Bit-Zeichen in der Konfiguration verwenden möchten, müssen Sie %				zuerst das Paket \pkg{inputenc} laden. Das Verwenden von Unicode wird 
% 		 	 ebenfalls unterstützt (wenn Sie \pkg{inputenc} mit der |utf8| oder |utf8x| %				 option laden).
%        Bei der Verwendung von mehreren Input-Kodierungen in einem Dokument, 
%				 werden 8-Bit-Zeichen in den Einstellungen nur zuverlässig funktionieren, 
%				 wenn Sie den |inputenc| Schlüssel spezifizieren.
%\changes{v2.3a}{2008/02/25}{add hint about \pkg{babel} having to be loaded first}
%  \item Beim Laden des Pakets mit der \opt{babel}-Option, sollten Sie das
%        \pkg{babel}-Paket vor \microtype\ laden.
%\changes{v2.3c}{2008/11/11}{add hint about partial incompatibility with \pkg{CJK}}
%  \item Es ist derzeit nicht möglich, Charakter-spezifische Einstellungen für 
%				 chinesische\slash japanischen\slash koreanischen Schriften zu erstellen. 
%				 Deshalb, ist die einzige mikro-typografische Erweiterung, die mit dem

%\paragraph{Here's the promised dirty trick}
% for users of older \pdftex\ versions, which works around the problem that the

% you do not want to create a clone of the font setup (this would require
% duplicating the \file{tfm}/\file{vf} files under a new name, and writing new
% \file{fd} files and \file{map} entries), you can load a minimally larger font
% for the paragraph in question. E.\,g., for a document typeset in 10\,pt:
%\begin{verbatim}[gobble=2,morekeywords={[0]{\expandpar}}]
% \SetExpansion
%    [ stretch = 30,
%      shrink  = 60,
%      step    =  5 ]
%    { encoding = *,
%      size = 10.001 }
%    { }
% \newcommand{\expandpar}[1]{{%
%    \fontsize{10.001}{\baselineskip}\selectfont #1\par}}
% % ...
% \expandpar{This paragraph contains an `unnecessary' widow.}
%\end{verbatim}
% Note that the \cmd\expandpar\ command can only be applied to complete
% paragraphs. If you are using Computer Modern Roman, you have to load the
% \pkg{fix-cm} package to be able to select fonts in arbitrary sizes. Finally,
% the reason I suggest to use a larger font, and not a smaller one, is to
% prevent a different design size being selected.

%\subsubsection{Hook into \LaTeX's font selection}\label{sssec:impl.hook}
%
% We append \cs{MT@setupfont} to \cmd\pickup@font, which is called by \LaTeX\
% every time a font is selected. We then check whether we've already seen this
% font, and if not, set it up for micro-typography.
% This ensures that we will catch all fonts, and that we will not set up fonts
% more than once. The whole package really hangs on this command.
%
% In contrast to the \pkg{pdfcprot} package, it is not necessary to declare in
% advance which fonts should benefit from micro-typographic treatment. Also,
% only those fonts that are actually being used will be set up.
%
% For my reference:
%\begin{itemize}
%  \item \cmd\pickup@font\ is called by \cmd\selectfont, \cmd\wrong@fontshape,
%     or \\ \cmd\getanddefine@fonts\ (for math).
%  \item \cmd\pickup@font\ calls \cmd\define@newfont.
%  \item \cmd\define@newfont\ may call (inside a group!)
%  \begin{itemize}
%     \item \cmd\wrong@fontshape, which in turn will call \cmd\pickup@font,
%        and thus \\ \cmd\define@newfont\ again, or
%     \item \cmd\extract@font.

% This hook may be used by font package authors, \eg, to declare alias fonts. If
% it is defined, it will be executed here, \ie, after the main configuration
% file has been loaded, and before the package options are evaluated.
%
% This hook was needed in versions prior to 1.9a to overcome the situation that
% (1)~the \microtype\ package should be loaded after all font defaults have
% been set up (hence, using \cmd\@ifpackageloaded\ in the font package was not
% viable), and (2)~checking \cmd\AtBeginDocument\ could be too late, since
% fonts might already have been loaded, and consequently set up, in the
% preamble. With the new deferred setup, one could live without this command,
% however, it remains here since it's simpler than testing whether the package
% was loaded both in the preamble as well as at the beginning of the document
% (which is what one would have to do).
%
% Package authors should check whether the command is already defined so that
% existing definitions by other packages aren't overwritten. Example:
%\begin{verbatim}
%\def\MinionPro@MT@Hook{\DeclareMicrotypeAlias{MinionPro-LF}{MinionPro}}
%\@ifpackageloaded{microtype}

% \cs{MicroType@Hook} with a capital |T| (which only existed in version 1.7) is
% provided for compatibility reasons. At some point in the future, it will no
% longer be available, hence it should not be used.

%\subsubsection{Computer Modern math}
%
% Now to the math symbols for Computer Modern Roman. Definitions have been
% extracted from \file{fontmath.ltx}.
%\changes{v1.2}{2004/10/02}{add settings for Computer Modern Roman math symbols}
% I did not spend too much time fiddling with these settings, so they can surely
% be improved.
%
% The math font `|operators|' (also used for the \cmd\mathrm\ and
% \cmd\mathbf\ alphabets) is |OT1/cmr|, which we've already set up above.
% It's declared as:
%\begin{verbatim}
%\DeclareSymbolFont{operators}  {OT1}{cmr}{m} {n}
%\SetSymbolFont{operators}{bold}{OT1}{cmr}{bx}{n}
%\end{verbatim}
%
% \cmd\mathit\ (|OT1/cmr/m/it|) is also already set up.
%
% There are (for the moment) no settings for \cmd\mathsf\ and \cmd\mathtt.
%
% Math font `|letters|' (also used as \cmd\mathnormal) is declared as:
%\begin{verbatim}
%\DeclareSymbolFont{letters}    {OML}{cmm}{m}{it}
%\SetSymbolFont{letters}  {bold}{OML}{cmm}{b}{it}

% (Wikipedia\footnote{\url{http://fr.wikipedia.org/wiki/Espace_typographique}, 5 July 2007.}
