+\embrac is placed under the terms of the LaTeX Project Public License,
+version 1.3 or later (\url{http://www.latex-project.org/lppl.txt}).
+It has the status ``maintained.''
+
+\embrac loads and needs the packages \paket{expl3}, \paket{xparse} and
+\paket{l3keys2e}, the first is part of the \paket{l3kernel} and the others are
+part of the \paket{l3packages}.
+\secidx*{License}\secidx*{Requirements}
+
+\section{Acknowledgements}
+I like to thank both Dominik Waßenhoven for inspiration~\cite{dtk12-dw} and
+Bruno Le Floch for providing code~\cite{lefloch11}. Without either of them this
+package probably wouldn't exist.
+
+\section{New}
+\begin{description}
+ \item[v0.1a] The command \cmd{RenewEmph} has been renamed into
+ \cmd{ChangeEmph} and a new slightly different \cmd{RenewEmph} has been added.
+\end{description}
+
+\section{About}\label{sec:about}\secidx{About}
+\begin{zitat}[{\cite[85]{bringhurst04}}]
+ Parentheses and brackets are not letters, and it makes little sense to speak of
+ them as roman or italic. There are vertical parentheses and sloped ones, and
+ the parentheses on italic fonts are almost always sloped, but vertical parentheses
+ are generally to be preferred. That means they must come from the roman font,
+ and may need extra spacing when used with italic letterforms.
+ 
+ The sloped square brackets usually found on italic fonts are, if anything, even
+ less useful than sloped parentheses. If, perish the thought, there were a book
+ or film entitled \emph*{The View from My [sic] Bed}, sloped brackets might be
+ useful as a way of indicating that the brackets and their contents are actually
+ part of the title. Otherwise, vertical brackets should be used, no matter whether
+ the text is roman or italic: \textquote{The View from My \emph{[sic]} Bed} and
+ \textquote{\emph{the view from my [sic] bed}.\kern.05em}
+\end{zitat}
+
+\noindent
+Both this quote from~\citetitle{bringhurst04} by Robert Bringhurst and the
+article \citetitle{dtk12-dw} by Dominik Waßenhoven~\cite{dtk12-dw} inspired
+this package. Indeed, \embrac heavily borrows from the code \citeauthor{dtk12-dw}
+provided in his article\manythanks. The code was originally provided by Bruno
+Le~Floch\manythanks\ as an answer to a question on \{TeX.SE\}~\cite{lefloch11}.
+
+\embrac tries to redefine \cmd{emph} and \cmd{textit} in a way that neither
+parentheses nor square brackets are sloped. In an ideal world you of course
+wouldn't need this package because the italic font you're using would have
+vertical parentheses and brackets by itself.
+
+\begin{beispiel}
+ \emph{This is emphasized [sic] text.} \\
+ \emph{This is emphasized text (as you can see).}
+\end{beispiel}
+\secidx*{About}
+
+\section{How it Works}\secidx{How it Works}
+Both the commands \cmd{emph} and \cmd{textit} are redefined:
+\begin{beschreibung}
+ \Befehl{emph}*{<emphasized text>}
+ \Befehl{textit}*{<text in italics>}
+\end{beschreibung}
+They now both have a \code{*} argument that restores the original behaviour.
+Otherwise they're used just as before.
+
+Let's see the example again:
+\begin{beispiel}
+ \emph{This is emphasized [sic] text.} \\
+ \emph{This is emphasized text (as you can see).}
+\end{beispiel}
+As you can see you don't have to do anything apart from loading \embrac in your
+preamble. Well -- that's actually not entirely true. You have to take care of the
+kerning of the parentheses and brackets. Otherwise things could look worse with
+\embrac than without.
+
+The following example demonstrates one point why you have to be very careful
+when using \embrac. Certain parenthesis-letter combinations might need adjustments
+of the kerning:
+\begin{beispiel}
+ \emph{This is (just) emphasized text.} \\
+ \emph{This is (\kern.1em just) emphasized text.}
+\end{beispiel}
+This of course strongly depends on the font you've chosen. Kerning is a very
+important aspect when using this package and you shouldn't use it without giving
+it a certain amount of attention. See the next section for more details.
+\secidx*{How it Works}
+
+\section{Adding More Brackets \&\ Adjusting the Kerning}
+\secidx{Adding More Brackets}\secidx{Adjusting the Kerning}
+If you want you can change the behaviour of \embrac. Maybe it should only affect
+squared brackets? Or curly braces, too? This can be done with the following
+commands. They all work locally which means if used inside a group outside of it
+everything stays what it was.
+\begin{beschreibung}
+ \Befehl{AddEmph}{<o>}\oa{<io-kern>,<oo-kern>}\ma{<c>}\oa{<ic-kern>,<oc-kern>}
+ \Befehl{ChangeEmph}{<o>}\oa{<io-kern>,<oo-kern>}\ma{<c>}\oa{<ic-kern>,<oc-kern>}
+ \Befehl{RenewEmph}{<o>}\oa{<io-kern>,<oo-kern>}\ma{<c>}\oa{<ic-kern>,<oc-kern>}
+ \Befehl{DeleteEmph}{<o>}\ma{<c>}
+\end{beschreibung}
+Here \code{<o>} means \emph{opening bracket} and \code{<c>} means \emph{closing
+bracket}. The kerning arguments are all four optional and require -- if given --
+to be a length. If they're not given \cmd{AddEmph} and \cmd{RenewEmph} insert
+\code{0pt} and \cmd{ChangeEmph} uses the value stored by \cmd{AddEmph} or
+\cmd{RenewEmph} before.
+
+\code{<io-kern>} is inserted after the opening bracket (inner opening),
+\code{<oo-kern>} is inserted before it (outer opening). \code{<ic-kern>} is
+inserted before the closing bracket (inner closing), \code{<oc-kern>} after it
+(outer closing).
+
+\embrac initially makes these definitions:
+\begin{beispiel}[code only]
+ % add some defaults:
+ \AddEmph{[}{]}[.04em,-.12em]
+ \AddEmph{(}[-.04em]{)}[,-.15em]
+\end{beispiel}
+
+This document however uses ``Linux Libertine O''\footnote{\url{http://www.linuxlibertine.org/}}
+both for the roman and the italic font and redefines them in this way (still not
+sure these are the best values):
+\begin{beispiel}[code only]
+ \ChangeEmph{[}[,.02em]{]}[.055em,-.08em]
+ \ChangeEmph{(}[-.01em,.04em]{)}[.04em,-.05em]
+\end{beispiel}
+
+You can change them as you wish, but be careful with the kerning! What's too less
+for one letter might be too much for others:
+\begin{beispiel}
+ \ChangeEmph{(}[.1em]{)}[.1em]
+ \emph{This is (just) emphasized text.} \\ % looks ok
+ \emph{This is emphasized text (as you can see).} % looks bad
+\end{beispiel}
+
+To see why it is important to pay attention to the kerning values let's look at
+how \embrac's features look without kerning (\ie, \code{0pt} for each value),
+with the default settings and with the settings for this document:
+
+\begin{center}
+ \begin{minipage}{.5\linewidth}
+  \textbf{No Kerning:}
+  
+  \RenewEmph{[}{]}\RenewEmph{(}{)}
+  \emph{This is emphasized [sic] text.} \\
+  \emph{This is emphasized text [as you can see].} \\
+  \emph{This is emphasized (sic) text.} \\
+  \emph{This is emphasized text (as you can see).}
+ \end{minipage}\bigskip
+ 
+ \begin{minipage}{.5\linewidth}
+  \textbf{\embrac's Default Kerning:}
+  
+  \RenewEmph{[}{]}[.04em,-.12em]\RenewEmph{(}[-.04em]{)}[,-.15em]
+  \emph{This is emphasized [sic] text.} \\
+  \emph{This is emphasized text [as you can see].} \\
+  \emph{This is emphasized (sic) text.} \\
+  \emph{This is emphasized text (as you can see).}
+ \end{minipage}\bigskip
+ 
+ \begin{minipage}{.5\linewidth}
+  \textbf{Adjusted Kerning:}
+  
+  \emph{This is emphasized [sic] text.} \\
+  \emph{This is emphasized text [as you can see].} \\
+  \emph{This is emphasized (sic) text.} \\
+  \emph{This is emphasized text (as you can see).}
+ \end{minipage}
+\end{center}
+
+Deleting a pair removes it completely from \embrac's mechanism. All information
+about the pair and it's kerning values will be lost. So if you want the effects
+to be temporary use grouping.
+\begin{beispiel}
+ \DeleteEmph[]
+ \emph{This is emphasized [sic] text.} \\
+ \emph{This is emphasized text (as you can see).}
+\end{beispiel}
+
+By the way: this packages provides a simple file \code{embrac\_kerning\_test.tex}
+for testing kerning values. You should find it in the same directory as this
+documentation.
+\secidx*{Adding More Brackets}\secidx*{Adjusting the Kerning}
+
+\section{biblatex Compatibility}\secidx{biblatex Compatibility}
+This is \embrac's only package option:
+\begin{beschreibung}
+ \Option{biblatex}{\default{true}|false}\Default{false} If set to true parentheses
+ and squared brackets as defined by \paket{biblatex} with \cmd{bibleftparen},
+ \cmd{bibrightparen}, \cmd{bibleftbracket} and \cmd{bibrightbracket} are treated
+ the same way (if not removed from the treatment with \cmd{DeleteEmph}).
+\end{beschreibung}
+
+\begin{beispiel}
+ % this document uses \usepackage[biblatex]{embrac}
+ \emph{Let's cite the quote from section~\ref{sec:about} again:~\cite{bringhurst04}}.
+\end{beispiel}
+\secidx*{biblatex Compatibility}
+
+\section{Turn \embrac Temporarily Off}\secidx{Turn \embrac Temporarily Off}
+Redefining \cmd{emph} and \cmd{textit} is not without danger. Sometimes you might
+find that you'd want to keep the original definition for a small portion of your
+document. You can use the following commands whose functions are obvious, I guess:
+\begin{beschreibung}
+ \Befehl{EmbracOff}
+ \Befehl{EmbracOn}
+\end{beschreibung}
+Both commands are local.
+
+This document for example uses the following lines because \paket{biblatex}
+complained when it tried to typeset the entry for~\cite{bringhurst04}. Using
+\cmd{DeleteEmph}[] would have worked as well.
+\begin{beispiel}[code only]
+ \EmbracOff
+ \printbibliography
+\end{beispiel}
+\secidx*{Turn \embrac Temporarily Off}
+
+\section{Watch out!}\secidx{Watch Out}
+Please be aware that \embrac does not affect \cmd{itshape} nor the commands
+\cmd{em} or \cmd{it} (which you shouldn't use in a \LaTeX\ document, anyway).
+\begin{beispiel}
+ \itshape This is italic [sic] text.
+\end{beispiel}
+\secidx*{Watch Out}
+
+\EmbracOff
+\printbibliography
+
+
+\setindexpreamble{Section titles are indicated \textbf{bold}, packages
+\textsf{sans serif}, commands \code{\textbackslash\textcolor{code}{brown}}
+ and options \textcolor{key}{\code{yellow}}.\par\bigskip}
