-\section{Example}\secidx{Example}
+\section{Example}
 A use case typically looks as follows:
-\begin{beispiel}
- \ReadCounterPattern{se.sse}
-\end{beispiel}
-where the key \code{se} stands for the current value of the \code{section} counter
-and \code{sse} for \code{subsection}, respectively. \code{se.sse} is an example
-for what will be called \emph{pattern}. The keys for the counters can have optional
-arguments that specify the format:
-\begin{beispiel}
- \stepcounter{subsection}
- \ReadCounterPattern{se[A](sse[r])}
-\end{beispiel}
-\code{A} stands for \cmd{Alph} and \code{r} for \cmd{roman}. A complete list can
-be found in table~\ref{tab:predefined:formats} on page~\pageref{tab:predefined:formats}.
-As you can see you can insert arbitrary other tokens in a pattern that won't be
-changed. It is important to notice, though, that the patterns are only replaced
-if they're \emph{not} placed in a braced group!
-
-\begin{beispiel}
- \ReadCounterPattern{{se[A](sse[r])}}
-\end{beispiel}
-
-I would imagine that the argument to \cmd{ReadCounterPattern} is usually
+\begin{example}[side-by-side]

-\section{Usage}\secidx{Usage}
-In the following description of the available commands the symbol \expsign{}
-means that the command is expandable, \unexpsign{} means that it isn't.
 
-In order to make counters known to \cntformats the following commands are used:
-\begin{beschreibung}
- \Befehl{AddCounterPattern}*[<module>]{<counter>}\ma{<pattern>}\newline
-   This command will make the (existing) counter \code{<counter>} known to
-   \cntformats and assign the pattern \code{<pattern>} to it.
- \Befehl{NewCounterPattern}*[<module>]{<counter>}\ma{<pattern>}\newline
-   This command will create a new counter \code{<counter>}, make it known to
-   \cntformats and assign the pattern \code{<pattern>} to it.
- \Befehl{ReadCounterFrom}[<module>]{<counter>}\ma{<internal cmd>}\newline
-   If you use one of the commands above with the starred version the number for
-   the pattern is not automatically fetched from the internal \cmd*{c@<counter>}.
-   This can now be assigned with \cmd{ReadCounterFrom} where \code{<internal cmd>}
-   is the macro that holds the number.
-\end{beschreibung}
+\section{Usage}
+In the following description of the available commands the symbol
+\textcolor{expandable}{\expandablesign} means that the command is expandable.
+
+In order to make counters known to \cntformats\ the following commands are used:
+\begin{commands}
+  \command{AddCounterPattern}[\sarg\oarg{module}\marg{counter}\marg{pattern}]
+    This command will make the (existing) counter \meta{counter} known to
+    \cntformats\ and assign the pattern \meta{pattern} to it.
+  \command{NewCounterPattern}[\sarg\oarg{module}\marg{counter}\marg{pattern}]
+    This command will create a new counter \meta{counter}, make it known to
+    \cntformats\ and assign the pattern \meta{pattern} to it.
+  \command{ReadCounterFrom}[\oarg{module}\marg{counter}\marg{internal cmd}]
+    If you use one of the commands above with the starred version the number
+    for the pattern is not automatically fetched from the internal
+    \cs*{c@\meta{counter}}.  This can now be assigned with
+    \cs{ReadCounterFrom}  where \meta{internal cmd} is the macro that holds
+    the number.
+\end{commands}
 The commands above can only be used in the document preamble.
 
 After the creation of these pattern markers one wants to be able to use them.
 There are a number of macros that allow different aspects of usage.
-\begin{beschreibung}
- \Befehl{ReadCounterPattern}[<module>]{<pattern>}\newline
-   Reads, interprets and prints a pattern.
- \expandable\Befehl{@cntfmts@parsed@pattern}\newline
-   After \cmd{ReadCounterPattern} has been used the current pattern interpretation
-   is stored in this macro. The \emph{interpretation} is \emph{not} what is printed.
-   See the examples below for details.
- \Befehl{ReadCounterPatternFrom}[<module>]{<macro that holds pattern>}\newline
-   Reads, interprets and prints a pattern that's stored in a macro.\\
-   Otherwise the same as \cmd{ReadCounterPattern}.
- \Befehl{SaveCounterPattern}{<cmd a>}\ma{<cmd b>}\ma{<pattern>}\newline
-   Saves the \code{<pattern>} in \code{<cmd a>} and the interpreted pattern in
-   \code{<cmd b>}.
- \Befehl{eSaveCounterPattern}[<module>]{<cmd a>}\ma{<cmd b>}\ma{<pattern>}\newline
-   Saves the \code{<pattern>} in \code{<cmd a>} and the expanded pattern in
-   \code{<cmd b>}.
- \Befehl{SaveCounterPatternFrom}[<module>]{<cmd a>}\ma{<cmd b>}\ma{<macro that
-   holds pattern>}\newline
-   Like \cmd{SaveCounterPattern} but reads the pattern from a macro.
- \Befehl{eSaveCounterPatternFrom}[<module>]{<cmd a>}\ma{<cmd b>}\ma{<macro that
-   holds pattern>}\newline
-   Like \cmd{eSaveCounterPattern} but reads the pattern from a macro.
-\end{beschreibung}
-
-The optional argument \code{<module>} should be specific for a package, say, so
+\begin{commands}
+  \command{ReadCounterPattern}[\oarg{module}\marg{pattern}]
+    Reads, interprets and prints a pattern.
+  \expandable\command{\at cntfmts\at parsed\at pattern}
+    After \cs{ReadCounterPattern} has been used the current pattern
+    interpretation is stored in this macro.  The \emph{interpretation} is
+    \emph{not} what is printed.  See the examples below for details.
+  \command{ReadCounterPatternFrom}[\oarg{module}\marg{macro that holds
+    pattern}]
+    Reads, interprets and prints a pattern that's stored in a macro.\\
+    Otherwise the same as \cs{ReadCounterPattern}.
+  \command{SaveCounterPattern}[\marg{cmd a}\marg{cmd b}\marg{pattern}]
+    Saves the \meta{pattern} in \meta{cmd a} and the interpreted pattern in
+    \meta{cmd b}.
+  \command{eSaveCounterPattern}[\oarg{module}\marg{cmd a}\marg{cmd
+    b}\marg{pattern}]
+    Saves the \meta{pattern} in \meta{cmd a} and the expanded pattern in
+    \meta{cmd b}.
+  \command{SaveCounterPatternFrom}[\oarg{module}\marg{cmd a}\marg{cmd
+    b}\marg{macro that holds pattern}]
+    Like \cs{SaveCounterPattern} but reads the pattern from a macro.
+  \command{eSaveCounterPatternFrom}[\oarg{module}\marg{cmd a}\marg{cmd
+    b}\marg{macro that holds pattern}]
+    Like \cs{eSaveCounterPattern} but reads the pattern from a macro.
+\end{commands}
+
+The optional argument \meta{module} should be specific for a package, say, so
 that different patterns for the \code{section} for example don't interfer with
-each other. If you leave the argument the default module \code{cntfmts} is used.

+used.
 
-The \ExSheets packages uses the commands with the module \code{exsheets}.
+The \ExSheets\ packages uses the commands with the module \code{exsheets}.
 You can find the following lines in \ExSheets' code:
-\begin{beispiel}[code only]
- \AddCounterPattern*[exsheets]{section}{se}
- \ReadCounterFrom[exsheets]{section} \l__exsheets_counter_sec_int
- \NewCounterPattern*[exsheets]{question}{qu}
- \ReadCounterFrom[exsheets]{question} \l__exsheets_counter_qu_int
-\end{beispiel}
+\begin{sourcecode}
+  \AddCounterPattern*[exsheets]{section}{se}
+  \ReadCounterFrom[exsheets]{section} \l__exsheets_counter_sec_int
+  \NewCounterPattern*[exsheets]{question}{qu}
+  \ReadCounterFrom[exsheets]{question} \l__exsheets_counter_qu_int
+\end{sourcecode}
 
 Now let's see a short example that hopefully explains what the macros do:
-\begin{beispiel}
- % preamble
- % \NewCounterPattern{testa}{ta}
- \setcounter{testa}{11}
- \ReadCounterPattern{ta}
- \ReadCounterPattern{ta[a]} \\
- \ttfamily\makeatletter
- \meaning\@cntfmts@parsed@pattern
- 
- \bigskip
- \SaveCounterPattern\tmpa\tmpb{ta[a]}

- \meaning\tmpb
- 
- \bigskip
- \eSaveCounterPattern\tmpa\tmpb{ta[a]}
- \meaning\tmpa \\
- \meaning\tmpb
-\end{beispiel}
-You can see that somehow additional (empty) groups and a \cmd*{relax} found their
-way into the interpreted and thus the expanded pattern. This is due to the fact
-that reading optional arguments expandably isn't easy and must have some safety
-net.

 in the preamble:
-\begin{beispiel}[code only]
- \usepackage{alphalph,fmtcount}
- \newcommand*\myoddnumber[1]{\the\numexpr2*(#1)-1\relax}
-
- \NewPatternFormat{aa}{\alphalph}

- \NewPatternFormat{x}{\myoddnumber}
-
- \newcounter{testa}
- \NewCounterPattern{testa}{ta}
- \setcounter{testa}{4}

-Then we can use the new pattern and the new formats as follows:\setcounter{testa}{4}

 \section{Additional Packages}
-\ExSheets actually bundles three packages: \ExSheets, \Tasks\ and \cntformats.
-\Tasks is described in part~\ref{part:tasks} and \cntformats in
-part~\ref{part:cntformats}.  These packages provide functionality that is used
-by \ExSheets.  They can, however, be used independently from \ExSheets.
+\ExSheets\ actually bundles four packages: \ExSheets, \ExSheetslistings\
+\Tasks\ and \cntformats.  \ExSheetslistings\ is an add-on to \ExSheets\
+that offers some functionality to use \pkg{listings} with \ExSheets.  It is
+presented in part~\ref{part:listings}.
+
+The \Tasks\ package and the \cntformats\ package have their own
+documentation.  These packages provide functionality that is used by
+\ExSheets.  They can, however, be used independently from \ExSheets.
 
 The package \cntformats\ is probably not really useful on a user-level but

 \section{Create Questions/Exercises and their Solutions}
 Now, let's start with the most important part: the questions and (possibly)
 their respective solutions.
-\subsection{The \code{question} Environment}\label{ssec:questions}
-Questions are written inside the \code{question} environment:
-\begin{beschreibung}
-  \Umg{question}[<options>]{\unskip\ma{<points>} ... }
-\end{beschreibung}
-\begin{beispiel}
- \begin{question}
-  This is our very first very difficult to solve question!
- \end{question}
-\end{beispiel}
+\subsection{The \env*{question} Environment}\label{ssec:questions}
+Questions are written inside the \env{question} environment:
+\begin{environments}
+  \environment{question}[\oarg{options}\marg{points}]
+    The main environment: creates a new exercise/question.  Both arguments are
+    optionial!
+\end{environments}
+\begin{example}
+  \begin{question}
+    This is our very first very difficult to solve question!
+  \end{question}
+\end{example}
 As you can see a heading is automatically created and the question is
 numbered.  You can of course change both the numbering and the naming, but
 more on that later.
 
-The \code{question} environment takes an optional argument \ma{<points>} that
+The \env{question} environment takes an optional argument \marg{points} that
 can be used to assign points to the question (as is common in written exams):
-\begin{beispiel}
- \begin{question}{3}
-  This is our first difficult question that is worth 3 points!
- \end{question}
-\end{beispiel}
+\begin{example}
+  \begin{question}{3}
+    This is our first difficult question that is worth 3 points!
+  \end{question}
+\end{example}
 These points are saved internally (see section~\ref{sec:points} for reasons
 why) and are written to the right margin next to the question heading in the
 default setting.
 
-You can also assign bonus points by inserting \code{<point>+<bonus points>} as
-argument.
-\begin{beispiel}
- \begin{question}{1+1}
-  This question is worth 1 point and 1 bonus point.
- \end{question}
- \begin{question}{+3}
-  This question is a bonus question. It is worth 3 bonus points.
- \end{question}
-\end{beispiel}
+You can also assign bonus points by inserting \code{\meta{point}+\meta{bonus
+    points}} as argument.
+\begin{example}
+  \begin{question}{1+1}
+    This question is worth 1 point and 1 bonus point.
+  \end{question}
+  \begin{question}{+3}
+    This question is a bonus question. It is worth 3 bonus points.
+  \end{question}
+\end{example}
 
 \sinceversion{0.3}On additional thing: you might want to define custom
 commands that should behave differently if they're inside or outside of the
-\code{question} environment.  In this case you can use these commands:
-\begin{beschreibung}
-  \expandable\Befehl{IfInsideQuestionTF}{<true code>}\ma{<false code>}
-  \expandable\Befehl{IfInsideQuestionT}{<true code>}

-\begin{beschreibung}
-  \Option[question]{type}{exam|exercise}\Default{exercise}

+\begin{commands}
+  \expandable\command{IfInsideQuestionTF}[\marg{true code}\marg{false code}]
+    Check if inside of a question and either leave \meta{true code} or
+    \meta{false code} in the input stream.
+  \expandable\command{IfInsideQuestionT}[\marg{true code}]
+    Check if inside of a question and either leave \meta{true code} in the
+    input stream if true.
+  \expandable\command{IfInsideQuestionF}[\marg{false code}]

-    
-    If you use \cmd*{usepackage}[ngerman]{babel}, for example, then the names
-    are ``\"Ubung and ``Aufgabe''.
-  \Option[question]{name}{<name>}\Default{}
-    sets a custom name.  All predefined names are discarded.
-  \Option[question]{print}{\default{true}|false}\Default{true}
-    prints or hides the question.
-  \Option[question]{ID}{<id>}\Default{}
-    assigns a custom \acs{id} to the question.  See section~\ref{ssec:ids} for
-    further information.
-  \Option[question]{label}{<label>}\Default{}
-    Places a \cmd*{label}{<label>} for the question.  This will overwrite any
-    label that is placed by the \key{auto-label} option.
-  \Option[question]{class}{<class>}\Default{}
-    assigns a class to the question.  See section~\ref{sec:classes} for

 to hide them in braces.

 possibilities.
 
-In the next subsections the usage of the command

-is discussed.
+In the next subsections the usage of the following command is discussed.
+\begin{commands}
+  \command{printsolutions}[\oarg{setting}]
+    Print solutions of questions(exercises.
+\end{commands}
 
 Before we do that a hint: remember that you can set the option \key{print}
 globally:
-\begin{beispiel}[code only]
- % in the preamble
- \SetupExSheets{solution/print=true}
-\end{beispiel}
+\begin{sourcecode}
+  % in the preamble
+  \SetupExSheets{solution/print=true}
+\end{sourcecode}
 
 Now if you want to typeset some text depending on the option being true or not
 you can use the following commands:
-\begin{beschreibung}
-  \expandable\Befehl{PrintSolutionsTF}{<true code>}\ma{<false code>}
-  \expandable\Befehl{PrintSolutionsT}{<true code>}
-  \expandable\Befehl{PrintSolutionsF}{<false code>}
-\end{beschreibung}
+\begin{commands}
+  \expandable\command{PrintSolutionsTF}[\marg{true code}\marg{false code}]
+    Checks if inside of a \env{solution} environment and either leaves the
+    \meta{true code} or the \meta{false code} in the input stream.
+  \expandable\command{PrintSolutionsT}[\marg{true code}]
+    Checks if inside of a \env{solution} environment and either leaves the
+    \meta{true code} in the input stream if yes.
+  \expandable\command{PrintSolutionsF}[\marg{false code}]
+    Checks if inside of a \env{solution} environment and either leaves the
+    \meta{false code} in the input stream if not.
+\end{commands}
 They might come in handy if you want two versions of an exercise sheet, one
 with the exercises and one with the solutions, and you want to add different
 titles to these versions, for instance.

+Yes, there's one more point: \cs{printsolutions} only knows the solutions

 explained in the next sections.

+\subsection{Print per chapter/section}
 \minisec{Current chapter/section}
 If you are not creating an exercise sheet or an exam but are writing a
 textbook you maybe want a section at the end of each chapter showing the
 solution to the exercises presented in that chapter.  In this case use the
 command as follows:
-\begin{beispiel}[code only]
- \printsolutions[section]
- % or
- \printsolutions[chapter]
-\end{beispiel}
+\begin{sourcecode}
+  \printsolutions[section]
+  % or
+  \printsolutions[chapter]
+\end{sourcecode}
 Again, this is pretty much self-explaining.  The solutions to the questions of
 the current chapter\footnote{Only if the document class you're using
   \emph{has} chapters, of course!} or section are printed.
-\begin{beispiel}
- \begin{question}
-  This is the first and only question in this section.
- \end{question}
- \begin{solution}
-  This will be one of a few solutions printed by the following call of
-  \cmd{printsolutions}.
- \end{solution}
- And now:
- \printsolutions[section]
-\end{beispiel}
+\begin{example}

+    This is the first and only question in this section.

+  \end{solution}
+  And now:
+  \printsolutions[section]
+\end{example}
 
 \minisec{Specific chapter/section}\label{sssec:print_specific_section}
 You can also print only the solutions from chapters or sections other than the
 current ones.  The syntax is fairly easy:
-\begin{beispiel}[below]
- \printsolutions[section={1-7,10}]
- % the same for chapters:
- % \printsolutions[chapter={1-7,10}]
-\end{beispiel}
-Don't forget that \cmd{printsolutions} cannot know the solutions from
+\begin{example}
+  \printsolutions[section={1-7,10}]
+  % the same for chapters:
+  % \printsolutions[chapter={1-7,10}]
+\end{example}
+Don't forget that \cs{printsolutions} cannot know the solutions from
 section~10 yet.  It is just used to demonstrate the syntax. You can also use
-an open range, \eg something like
-\begin{beispiel}[code only]
- \printsolutions[section={-4,10-}]
-\end{beispiel}
+an open range, \eg, something like
+\begin{sourcecode}
+  \printsolutions[section={-4,10-}]
+\end{sourcecode}
 This would print the solutions from sections~1--4 and from all sections with
-number 10\footnote{Or rather where \cmd{value}{section} is 10 or greater --
+number 10\footnote{Or rather where \cs*{value}\Marg{section} is 10 or greater --
   the actual counter formatting is irrelevant.} and greater.
 
 There is an obvious disadvantage: you have to know the section numbers!  But
-there is a solution: use the package option \key{use-ref}{true}.  Then you can
-do something like
-\begin{beispiel}[code only]
- % in the preamble:
- \usepackage[use-ref]{exsheets}
- % somewhere in your code after \section{A really cool section title}:

- \printsolutions[section={-\S{sec:ReallyCool}}]
- % which will print all solutions from questions up to and
- % including the really cool section
-\end{beispiel}
-With the package option \key{use-ref}{true} each usage of \cmd{label} will
+there is a solution: use the package option \keyis{use-ref}{true}.  Then you

+  \printsolutions[section={-\S{sec:ReallyCool}}]
+  % which will print all solutions from questions up to and
+  % including the really cool section
+\end{sourcecode}
+With the package option \keyis{use-ref}{true} each usage of \cs*{label} will
 create additional labels (one preceded with \code{exse:} and another one with
 \code{exch:}) which store the section number and the chapter number,
-respectively.  These are used internally by two commands \cmd{S} and \cmd{C}
+respectively.  These are used internally by two commands \cs{S} and \cs{C}

-
-Since some packages like the well known \paket{hyperref} for example redefine
-\cmd{label} \key{use-ref} won't work in together with it.  In this case don't
-use \key{use-ref} and set \cmd{exlabel}{<label>} instead to remember the

-\subsection{Print by \acs{id}}\label{ssec:ids}\secidx[print!by ID]{solutions}
+\subsection{Print by \acs{id}}\label{ssec:ids}
 Now comes the best part: you can also print selected solutions!  Every
 question has an \acs{id}.  To see which \acs{id} a question has you can call
 the following command:
-\begin{beschreibung}
-  \Befehl{DebugExSheets}{true|false}
-  \Befehl{CurrentQuestionID}\newline\sinceversion{0.4a}%
-    expands to the current question \acs{id} (after two expansions).
-\end{beschreibung}
+\begin{commands}
+  \command{DebugExSheets}[\Marg{\choices{true,false}}]
+    Enable or disable visual \ExSheets' debugging.
+  \command{CurrentQuestionID}
+    \sinceversion{0.4a}Expands to the current question \acs{id} (after two
+    expansions).
+\end{commands}
 Let's create some more questions and take a look what this command does:
-\begin{beispiel}
- \DebugExSheets{true}
- \begin{question}[ID=nice!]
-  A question with a nice \acs{id}!
- \end{question}
- \begin{solution}
-  The solution to the question with the nice \acs{id}.
- \end{solution}
- \begin{question}{3.75}
-  Yet another question. But this time with quarter points!
- \end{question}
- \begin{solution}
-  Yet another solution.
- \end{solution}
-\end{beispiel}
+\begin{example}
+  \DebugExSheets{true}
+  \begin{question}[ID=nice!]
+    A question with a nice \acs{id}!
+  \end{question}
+  \begin{solution}
+    The solution to the question with the nice \acs{id}.
+  \end{solution}
+  \begin{question}{3.75}
+    Yet another question. But this time with quarter points!
+  \end{question}
+  \begin{solution}
+    Yet another solution.
+  \end{solution}
+\end{example}
 
 So now we can call some specific solutions:
-\begin{beispiel}
- \printsolutions[byID={first,nice!,10,14}]
-\end{beispiel}
-This makes use of the \paket{l3sort} package which at the time of writing is
+\begin{example}
+  \printsolutions[byID={first,nice!,10,14}]
+\end{example}
+This makes use of the \pkg{l3sort} package which at the time of writing is
 still considered experimental.  In case you wonder where solution~14 is:
 question~14 has no solution given.
 
 If you don't want that the solutions are sorted automatically but appear in
 the order given you can use the option
-\begin{beschreibung}
-  \Option[solution]{sorted}{\default{true}|false}\Default{true}

 \section{Adding and Using Additional Information to Questions}\label{sec:additional_info}
-\secidx{Additional Information to Questions}
 For managing lots of questions and corresponding solutions it can be very
 useful to be able to save and recover additional information to the questions.
 This is possible with the following commands.  First the ones for saving:
-\begin{beschreibung}
-  \Befehl{DeclareQuestionProperty}{<name>}\newline
-    This command defines a question property \code{<name>}.  It can only be
+\begin{commands}
+  \command{DeclareQuestionProperty}[\marg{name}]
+    This command defines a question property \meta{name}.  It can only be
     used in the document preamble.
-  \Befehl{SetQuestionProperties}{<name>=<value>,...}\newline
+  \command{SetQuestionProperties}[\Marg{\meta{name}=\meta{value},...}]
     Set the properties for a specific question. this command can only be used
-    inside the \code{question} environment.
-\end{beschreibung}
+    inside the \env{question} environment.
+\end{commands}
 Now the commands for recovering the properties:
-\begin{beschreibung}
-  \Befehl{QuestionNumber}{<id>}\newline
-    Recover the number of the question with the \acs{id} \code{<id>}.  The
+\begin{commands}
+  \command{QuestionNumber}[\marg{id}]
+    Recover the number of the question with the \acs{id} \meta{id}.  The
     number is displayed according to the format set with
-    \key{counter-format}.
-  \Befehl{GetQuestionProperty}{<name>}\ma{<id>}\newline
-    Recover the property \code{<name>} of the question with the \acs{id}
-    \code{<id>}.  Of course the property must have been declared before.
-\end{beschreibung}
-
+    \option{counter-format}.
+  \command{GetQuestionProperty}[\marg{name}\marg{id}]
+    Recover the property \meta{name} of the question with the \acs{id}
+    \meta{id}.  Of course the property must have been declared before.
+\end{commands}
+  
 Let's say we have declared the properties \code{notes}, \code{reference} and
 \code{topic}.  By default the property \code{points} is available and gets the
 value of the optional argument of the \code{question} environment.
 
 We can now do the following:
-\begin{beispiel}
- % uses `biblatex'
- \begin{question}[ID=center,topic=LaTeX]{3}
-  Explain how you could center text in a \LaTeX\ document.
-  \SetQuestionProperties{
-    topic     = \TeX/\LaTeX ,
-    notes     = {How to center text.},
-    reference = {\textcite{companion}}}
- \end{question}
- \begin{solution}
-  To center a short part of the text body one can use the \texttt{center}
-  environment (\points{1}). Inside an environment like \texttt{table} one
-  should use \texttt{\string\centering} (\points{1}). For single lines
-  there is also the \texttt{\string\centerline} command (\points{1}).
- \end{solution}
- \begin{question}[ID=knuthbooks,topic=LaTeX]{2}
-  Name two books by D.\,E.\,Knuth.
-  \SetQuestionProperties{
-    topic     = \TeX/\LaTeX ,
-    notes     = {Books by Knuth.},
-    reference = {\textcite{knuth:ct:a,knuth:ct:b,knuth:ct:c,knuth:ct:d,knuth:ct:e}}}
- \end{question}
- \begin{solution}
-  For example two volumes from \citetitle{knuth:ct}:
-  \citetitle{knuth:ct:a,knuth:ct:b,knuth:ct:c,knuth:ct:d,knuth:ct:e}. Each valid
-  answer is worth \points{1}
- \end{solution}
-\end{beispiel}
+\begin{example}
+  % uses `biblatex'
+  \begin{question}[ID=center,topic=LaTeX]{3}
+    Explain how you could center text in a \LaTeX\ document.
+    \SetQuestionProperties{

+       notes     = {How to center text.},
+       reference = {\textcite{companion}}}
+  \end{question}
+  \begin{solution}
+    To center a short part of the text body one can use the \env*{center}
+    environment (\points{1}). Inside an environment like \env*{table} one
+    should use \cs*{centering} (\points{1}). For single lines there is also
+    the \cs*{centerline} command (\points{1}).
+  \end{solution}
+  \begin{question}[ID=knuthbooks,topic=LaTeX]{2}

+    valid answer is worth \points{1}
+  \end{solution}
+\end{example}
 
 It is now possible to recover these values later:

-      & Note       & \GetQuestionProperty{notes}{knuthbooks} \\
-   \bottomrule

- \end{center}
-\end{beispiel}

-\sinceversion{0.7a}If you use the package option \key{auto-label} the

 Please note that these properties \emph{are not the same} as the dividing
 concepts explained in section~\ref{sec:dividing-concepts} although they may
 seem similar in meaning or even have the same name.
 
 \sinceversion{0.3}There are additional commands that might prove useful:
-\begin{beschreibung}
-  \Befehl{ForEachQuestion}{<code to be executed for each used question>}\newline
+\begin{commands}
+  \command{ForEachQuestion}[\marg{code to be executed for each used question}]
     Inside the argument one can refer to the \ac{id} of a question with
     \code{\#1}.  Beware that this command only knows of questions used before
     it is issued.
-  \expandable\Befehl{numberofquestions}\newline
+  \expandable\command{numberofquestions}
     Returns the current number of used questions.  Beware that this command
     only knows of questions used before it is issued.
-  \expandable\Befehl{iflastquestion}{<true code>}\ma{<false code>}\newline
+  \expandable\command{iflastquestion}[\marg{true code}\marg{false code}]
     Although this command is available in the whole document it is only useful
-    inside \cmd{ForEachQuestion}.  It tells you if the end of the loop is
+    inside \cs{ForEachQuestion}.  It tells you if the end of the loop is
     reached or not.
-\end{beschreibung}
+\end{commands}
 For example one could use these commands to create a grading table:
-\begin{beispiel}[code only]
- \begin{tabular}{|l|*{\numberofquestions}{c|}c|}\hline
-  Question &
-    \ForEachQuestion{\QuestionNumber{#1}\iflastquestion{}{&}} &
-    Total \\ \hline
-  Points   &
-    \ForEachQuestion{\GetQuestionProperty{points}{#1}\iflastquestion{}{&}} &
-    \pointssum* \\ \hline
-  Reached  &
-    \ForEachQuestion{\iflastquestion{}{&}} & \\ \hline
- \end{tabular}
-\end{beispiel}
+\begin{sourcecode}
+  \begin{tabular}{|l|*{\numberofquestions}{c|}c|}\hline
+    Question &
+      \ForEachQuestion{\QuestionNumber{#1}\iflastquestion{}{&}} &
+      Total \\ \hline
+    Points   &
+      \ForEachQuestion{\GetQuestionProperty{points}{#1}\iflastquestion{}{&}} &
+      \pointssum* \\ \hline
+    Reached  &
+      \ForEachQuestion{\iflastquestion{}{&}} & \\ \hline
+  \end{tabular}
+\end{sourcecode}
 For four questions the table now would look similar to
 figure~\ref{fig:grading-table}.

+\part{The \ExSheetslistings\ Package \exsheetslistingsverion}\label{part:listings}
+\section{The Problem}
+I knew the day would come when people would ask how to include verbatim
+material in the \env{question} and \env{solution} environments.  Since they're
+defined with the \pkg{environ} package they're reading their environment
+bodies like macros read their arguments.  This makes it impossible to use
+verbatim material inside them\footnote{See the \TeX\ \acs{faq}
+  \url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=verbwithin} for reasons
+  why.}.  Now the day has come~\cite{tex.sx:131546}.  Soon after the first
+question appeared I wrote the first draft for \ExSheetslistings\ for a question
+on \TeX.sx~\cite{tex.sx:133907}.
+
+\section{The Proposed Solution}
+
+The \ExSheetslistings\ package defines \pkg{listings} environments that place
+their contents inside \env{question} and \env{solution} environments.  They do
+this by writing the listing to a unique auxiliary file --
+questions to \code{\cs*{jobname}-ex\meta{num}.lst} and solutions to
+\code{\cs*{jobname}-sol\meta{num}.lst} where \meta{num} is an increasing
+integer that ensures that each listing gets a unique file name.  Those files
+are then included with \cs{lstinutlisting} if and when the question or
+solution is printed.
+
+\begin{environments}
+  \environment{lstquestion}[\oarg{options}]
+    A \pkg{listings} environment placed in a \env{question}.
+  \environment{lstsolution}[\oarg{options}]
+    A \pkg{listings} environment placed in a \env{solution}.
+\end{environments}
+
+All you have to do to use the package is loading it the usual way:
+\begin{sourcecode}
+  \usepackage{exsheets-listings}
+\end{sourcecode}
+This will also load the packages \ExSheets\ and \pkg{listings} if they're not
+loaded already.
+
+\begin{example}
+  % this uses my listings style used in this documentation for all pieces of
+  % code:
+  \begin{lstquestion}[%
+      pre=Explain what this piece of \LaTeX\ code does:,
+      listings={style=cnltx}]
+    \begingroup\expandafter\expandafter\expandafter\endgroup
+    \expandafter\ifx\csname foo\endcsname\relax
+    ...
+    \else
+    ...
+    \fi
+  \end{lstquestion}
+\end{example}
+
+The example already shows two options of these environments.  Here is the
+complete list:
+\begin{options}
+  \keyval{pre}{text}
+    \meta{text} is placed before the code in the \env{question} or
+    \env{solution} environment.
+  \keyval{post}{text}
+    \meta{text} is placed after the code in the \env{question} or
+    \env{solution} environment.
+  \keyval{options}{options}
+    Options passed to underlying the \env{question} or \env{solution}
+    environment.
+  \keyval{points}{points}
+    The points assigned to the underlying \env{question} environment.
+  \keyval{listings}{options}
+    Options passed to the underlying \pkg{listings} environment.
+\end{options}
+
+There are also two new options for \ExSheets\ that can be set with
+\cs{SetupExSheets}:
+\begin{options}
+  \keyval{listings}{options}\Module{question}
+    Options passed to the underlying \pkg{listings} environment of
+    \env{lstquestion}.
+  \keyval{listings}{options}\Module{solution}
+    Options passed to the underlying \pkg{listings} environment of
+    \env{lstsolution}.
+\end{options}
+
+\section{Own Environments}
+
+\begin{commands}
+  \command{NewLstQuSolPair}[\oarg{options for both environments}\marg{lst question
+    env}\marg{question env}\oarg{options for lst question env}\marg{lst
+    solution env}\marg{solution env}\oarg{options for lst solution env}]
+    Defines two new \pkg{listings} environments that place the listing in a
+    question environment \meta{question env} or a solution environment
+    \meta{solution env}.  Those underlying environments should be
+    environments as defined by \cs{NewQuSolPair}.  The different options
+    allow to preset options for the newly defined environments.
+\end{commands}
+
+The existing environments have been defined like this:
+\begin{sourcecode}
+  \NewLstQuSolPair{lstquestion}{question}{lstsolution}{solution}
+\end{sourcecode}

+The \env{tasks} environment is similar to a list like \env{enumerate} but not
 the same.  Here are some of the differences:
 \begin{itemize}
-\item A first difference: there is no pagebreak possible inside an item but
-  only between items.
-\item A second difference: the enumeration default is a), b), c) \ldots
-\item A third difference: there is a split at \emph{every} occurrence of the
-  item separator.  For this reason the default separator is not \cmd*{item}
-  but \cmd{task} so it is unique to this environment only.
-\item A fourth difference: the \code{tasks} environment cannot be nested.
-  You can, however, use an \code{itemize} environment or something in it.
-\item A fifth difference: verbatim material cannot be used in it.  You'll
-  have to use \cmd*{string}, \cmd*{texttt} or \cmd*{detokenize}.  If this
-  won't suffice then don't use \code{tasks}.

-\section{Available Options}\secidx{Options}\label{sec:tasks:options}
-The \Tasks package has one package option which also is called when you load
-\ExSheets with the \key{load-tasks} option.
-\begin{beschreibung}
- \Option{more}\newline
-   load additional instances for the \code{tasks} object, details are explained
-   later in section~\ref{sec:tasks:instances}.
-\end{beschreibung}
-
-The environment itself has some more options, namely these:
-\begin{beschreibung}
- \Option{style}{<instance>}\Default{}
-   Choose the instance to be used.  Read more on this in
-   section~\ref{sec:tasks}.
- \Option{counter-format}{<counter specs>}\Default{}
-   \sinceversion{0.9}Sets a custom label.  The letters \code{tsk} are replaced
-   with the task-counter.  An optional argument directly following these
-   letters specifies the counter format: \code{1}: \cmd{arabic}, \code{a}:
-   \cmd{alph}, \code{A}: \cmd{Alph}, \code{r}: \cmd{roman} and \code{R}:
-   \cmd{Roman}.
- \Option{label-format}{<code>}\Default{}
-   \changedversion{0.9}Can be used to apply a formatting like, \emph{e.g.},
-   \cmd*{bfseries} to the labels.
- \Option{label}{<code>}\Default{}
-   \changedversion{0.9}Overwrite the automatic label to a custom one.
- \Option{label-width}{<dim>}\Default{1em}
-   Sets the width of the item labels.
- \Option{label-offset}{<dim>}\Default{.3333em}
-   \sinceversion{0.7}Sets the offset, \emph{i.e.}, the distance between label
-   and item.
- \Option{item-indent}\Default{2.5em}
-   \sinceversion{0.9a}The indent of an item, \textit{i.e.}, the horizontal
-   space available for both label and label-offset.  If \code{indent =
-     label-width + label=offset} the label will align with the textblock above
-   (if \key{label-align}{left} is set).
- \Option{label-align}{left|right|center}\Default{left}
-   \sinceversion{0.7}Determines how the labels are aligned within the
-   label-box whose width is set with \key{label-width}.
- \Option{before-skip}{<skip>}\Default{0pt}
-   Sets the skip before the list.
- \Option{after-skip}{<skip>}\Default{0pt}
-   Sets the skip after the list.
- \Option{after-item-skip}{<skip>}\Default{1ex plus 1ex minus 1ex}
-   \sinceversion{0.9}This vertical skip is inserted between rows of items.
- \Option{resume}{\default{true}|false}\Default{false}
-   The enumeration will resume from a previous \code{tasks} environment.  In
-   order to use this option properly you shouldn't mix different \code{tasks}
-   environments that both count their items.
-\end{beschreibung}
-These options can also be set using a setup command:
-\begin{beschreibung}
- \Befehl{settasks}{<options>}
-\end{beschreibung}
+Sometimes it may come in handy if the current\sinceversion{0.9} row of items
+could be terminated and a new one is started.  This is possible with the
+following command:
+\begin{commands}
+  \command{startnewitemline}
+    Introduce a new line in a \env{tasks} environment.
+\end{commands}
+\begin{example}
+  \begin{tasks}(4)
+    \task the first
+    \task the second
+    \task the third
+    \task the fourth
+    \task \rlap{the fifth item is way too long for this so we start a new row}
