\section{2   Body Elements%
  \label{body-elements}%
}


\subsection{2.1   Paragraphs%
  \label{paragraphs}%
}

A paragraph.


\subsubsection{2.1.1   Inline Markup%
  \label{inline-markup}%
}

Paragraphs contain text and may contain inline markup: \emph{emphasis},
\textbf{strong emphasis}, \texttt{inline literals}, standalone hyperlinks
(\url{http://www.python.org}), external hyperlinks (\href{http://www.python.org/}{Python}\DUfootnotemark{id30}{id29}{5}), internal
cross-references (\hyperref[example]{example}), external hyperlinks with embedded URIs
(\href{http://www.python.org}{Python web site}), \href{http://www.python.org/}{anonymous hyperlink
references}\DUfootnotemark{id40}{id29}{5} (\href{http://docutils.sourceforge.net/}{a second reference}\DUfootnotemark{id42}{id41}{9}), footnote references (manually
numbered\DUfootnotemark{id1}{id8}{1}, anonymous auto-numbered\DUfootnotemark{id2}{id12}{3}, labeled auto-numbered\DUfootnotemark{id3}{label}{2}, or symbolic\DUfootnotemark{id4}{id13}{*}), citation references (\hyperlink{cit2002}{[CIT2002]}),
substitution references (\includegraphics{../../../docs/user/rst/images/biohazard.png}), and %
\phantomsection\label{inline-hyperlink-targets}inline hyperlink targets
(see \hyperref[targets]{Targets} below for a reference back to here).  Character-level
inline markup is also possible (although exceedingly ugly!) in \emph{re}\texttt{Structured}\emph{Text}.  Problems are indicated by %
\raisebox{1em}{\hypertarget{id28}{}}\hyperlink{id27}{\textbf{\color{red}|problematic|}} text
(generated by processing errors; this one is intentional).  Here is a
reference to the \hyperref[doctitle]{doctitle} and the \hyperref[subtitle]{subtitle}.

The default role for interpreted text is \DUroletitlereference{Title Reference}.  Here are
some explicit interpreted text roles: a PEP reference (\href{http://www.python.org/dev/peps/pep-0287}{PEP 287}); an
RFC reference (\href{http://tools.ietf.org/html/rfc2822.html}{RFC 2822}); an abbreviation (\DUrole{abbreviation}{abb.}), an acronym
(\DUrole{acronym}{reST}), code (\texttt{\DUrole{code}{print \textquotedbl{}hello world\textquotedbl{}}}); a \textsubscript{subscript};
a \textsuperscript{superscript} and explicit roles for \DUroletitlereference{Docutils}’
\emph{standard} \textbf{inline} \texttt{markup}.

% DO NOT RE-WRAP THE FOLLOWING PARAGRAPH!

Let’s test wrapping and whitespace significance in inline literals:
\texttt{This is an example of --inline-literal --text, --including some--
strangely--hyphenated-words. ~Adjust-the-width-of-your-browser-window
to see how the text is wrapped. ~-- ---- -------- ~Now note ~ ~the
spacing ~ ~between the ~ ~words of ~ ~this sentence ~ ~(words
should ~ ~be grouped ~ ~in pairs).}

If the \texttt{--pep-references} option was supplied, there should be a
live link to PEP 258 here.


\subsection{2.2   Bullet Lists%
  \label{bullet-lists}%

\begin{itemize}
\item A bullet list

\begin{itemize}
\item Nested bullet list.

\subsection{2.4   Definition Lists%
  \label{definition-lists}%
}

\begin{description}
\item[{Term}] \leavevmode

Definition paragraph 1.

Definition paragraph 2.

\item[{Term}] \leavevmode 
Definition

\item[{Term}] \leavevmode (\textbf{classifier one})(\textbf{classifier two})
Definition

\end{description}


\subsection{2.5   Field Lists%
  \label{field-lists}%
}

\begin{DUfieldlist}
\item[{what:}]
Field lists map field names to field bodies, like database
records.  They are often part of an extension syntax.  They are
an unambiguous variant of RFC 2822 fields.

\item[{how arg1 arg2:}]
The field marker is a colon, the field name, and a colon.

The field body may contain one or more body elements, indented
relative to the field marker.

\item[{credits:}]
\DUrole{credits}{This paragraph has the \DUroletitlereference{credits} class set.  (This is actually not
about credits but just for ensuring that the class attribute
doesn’t get stripped away.)}
\end{DUfieldlist}


\subsection{2.6   Option Lists%
  \label{option-lists}%
}

For listing command-line options:

\begin{DUoptionlist}
\item[-a]  command-line option “a”

\item[-b file]  options can have arguments
and long descriptions

\item[--long]  options can be long also

\item[--input=file]  long options can also have
arguments

\item[--very-long-option]  The description can also start on the next line.

The description may contain multiple body elements,
regardless of where it starts.

\item[-x, -y, -z]  Multiple options are an “option group”.

\item[-v, --verbose]  Commonly-seen: short \& long options.

\item[-1 file, --one=file, --two file]  Multiple options with arguments.

\item[/V]  DOS/VMS-style options too
\end{DUoptionlist}

There must be at least two spaces between the option and the
description.


\subsection{2.7   Literal Blocks%
  \label{literal-blocks}%
}

Literal blocks are indicated with a double-colon (“::”) at the end of
the preceding paragraph (over there \texttt{-->}).  They can be indented:

\begin{quote}
\begin{alltt}
if literal_block:
    text = 'is left as-is'
    spaces_and_linebreaks = 'are preserved'
    markup_processing = None
\end{alltt}
\end{quote}

Or they can be quoted without indentation:

\begin{quote}
\begin{alltt}
>> Great idea!
>
> Why didn't I think of that?
\end{alltt}
\end{quote}


\subsection{2.8   Line Blocks%
  \label{line-blocks}%
}

This section tests line blocks.  Line blocks are body elements which
consist of lines and other line blocks.  Nested line blocks cause
indentation.

\begin{DUlineblock}{0em}
\item[] This is a line block.  It ends with a blank line.
\item[]
\begin{DUlineblock}{\DUlineblockindent}
\item[] New lines begin with a vertical bar (“|”).
\item[] Line breaks and initial indent are significant, and preserved.
\item[]
\begin{DUlineblock}{\DUlineblockindent}
\item[] Continuation lines are also possible.  A long line that is intended
to wrap should begin with a space in place of the vertical bar.
\end{DUlineblock}
\item[] The left edge of a continuation line need not be aligned with
the left edge of the text above it.
\end{DUlineblock}
\end{DUlineblock}

\begin{DUlineblock}{0em}
\item[] This is a second line block.
\item[] 
\item[] Blank lines are permitted internally, but they must begin with a “|”.
\end{DUlineblock}

Another line block, surrounded by paragraphs:

\begin{DUlineblock}{0em}
\item[] And it’s no good waiting by the window
\item[] It’s no good waiting for the sun
\item[] Please believe me, the things you dream of
\item[] They don’t fall in the lap of no-one
\end{DUlineblock}

Take it away, Eric the Orchestra Leader!

\begin{quote}
\begin{DUlineblock}{0em}
\item[] A one, two, a one two three four
\item[] 
\item[] Half a bee, philosophically,
\item[]
\begin{DUlineblock}{\DUlineblockindent}
\item[] must, \emph{ipso facto}, half not be.
\end{DUlineblock}
\item[] But half the bee has got to be,
\item[]
\begin{DUlineblock}{\DUlineblockindent}
\item[] \emph{vis a vis} its entity.  D’you see?
\item[] 
\end{DUlineblock}
\item[] But can a bee be said to be
\item[]
\begin{DUlineblock}{\DUlineblockindent}
\item[] or not to be an entire bee,
\item[]
\begin{DUlineblock}{\DUlineblockindent}
\item[] when half the bee is not a bee,
\item[]
\begin{DUlineblock}{\DUlineblockindent}
\item[] due to some ancient injury?
\item[] 
\end{DUlineblock}
\end{DUlineblock}
\end{DUlineblock}
\item[] Singing…
\end{DUlineblock}
\end{quote}

A line block, like the following poem by Christian Morgenstern, can
also be centre-aligned:

\begin{selectlanguage}{german}
\begin{DUlineblock}{0em}
\centering
\item[] \textbf{Die Trichter}
\item[] 
\item[] Zwei Trichter wandeln durch die Nacht.
\item[] Durch ihres Rumpfs verengten Schacht
\item[] fließt weißes Mondlicht
\item[] still und heiter
\item[] auf   ihren
\item[] Waldweg
\item[] u. s.
\item[] w.
\item[] 
\end{DUlineblock}
\end{selectlanguage}


\subsection{2.9   Block Quotes%
  \label{block-quotes}%
}

Block quotes consist of indented body elements:

\begin{quote}
My theory by A. Elk.  Brackets Miss, brackets.  This theory goes
as follows and begins now.  All brontosauruses are thin at one
end, much much thicker in the middle and then thin again at the
far end.  That is my theory, it is mine, and belongs to me and I
own it, and what it is too.
\nopagebreak

\raggedleft —Anne Elk (Miss)
\end{quote}

The language of a quote (like any other object) can be specified by
a class attribute:

% 

\begin{selectlanguage}{french}
\begin{quote}
ReStructuredText est un langage de balisage léger utilisé
notamment dans la documentation du langage Python.
\end{quote}
\end{selectlanguage}


\subsection{2.10   Doctest Blocks%
  \label{doctest-blocks}%
}

\begin{quote}
\begin{alltt}
>>> print 'Python-specific usage examples; begun with ">>>"'
Python-specific usage examples; begun with ">>>"
>>> print '(cut and pasted from interactive Python sessions)'
(cut and pasted from interactive Python sessions)
\end{alltt}
\end{quote}


\subsection{2.11   Footnotes%
  \label{footnotes}%
}
%
\DUfootnotetext{id8}{id1}{1}{%
A footnote contains body elements, consistently indented by at
least 3 spaces.

This is the footnote’s second paragraph.
}
%
\DUfootnotetext{label}{id3}{2}{\phantomsection\label{label}%
Footnotes may be numbered, either manually (as in\DUfootnotemark{id9}{id8}{1}) or
automatically using a “\#”-prefixed label.  This footnote has a

footnote reference (\DUfootnotemark{id10}{label}{2}) and as a \hyperref[label]{hyperlink reference}.
}
%
\DUfootnotetext{id12}{id2}{3}{%
This footnote is numbered automatically and anonymously using a
label of “\#” only.

This is the second paragraph.

And this is the third paragraph.
}
%
\DUfootnotetext{id13}{id4}{*}{%
Footnotes may also use symbols, specified with a “*” label.
Here’s a reference to the next footnote:\DUfootnotemark{id14}{id15}{†}.
}
%
\DUfootnotetext{id15}{id14}{†}{%

%
\DUfootnotetext{id16}{id16}{4}{%
Here’s an unreferenced footnote, with a reference to a
nonexistent footnote:%
\raisebox{1em}{\hypertarget{id17}{}}\hyperlink{id47}{\textbf{\color{red}{[}5{]}\_}}.
}


\subsection{2.12   Citations%
  \label{citations}%
}
\begin{figure}[b]\raisebox{1em}{\hypertarget{cit2002}{}}[CIT2002]
Citations are text-labeled footnotes. They may be
rendered separately and differently from footnotes.
\end{figure}

Here’s a reference to the above, \hyperlink{cit2002}{[CIT2002]}, and a %
\raisebox{1em}{\hypertarget{id19}{}}\hyperlink{id48}{\textbf{\color{red}{[}nonexistent{]}\_}}
citation.


\subsection{2.13   Targets%
  \label{targets}%
  \label{another-target}%
}

\phantomsection\label{example}
This paragraph is pointed to by the explicit “example” target. A
reference can be found under \hyperref[inline-markup]{Inline Markup}, above. \hyperref[inline-hyperlink-targets]{Inline
hyperlink targets} are also possible.

Section headers are implicit targets, referred to by name. See
\hyperref[targets]{Targets}, which is a subsection of \hyperref[body-elements]{Body Elements}.

Explicit external targets are interpolated into references such as
“\href{http://www.python.org/}{Python}\DUfootnotemark{id31}{id29}{5}”.

Targets may be indirect and anonymous.  Thus \hyperref[targets]{this phrase} may also
refer to the \hyperref[targets]{Targets} section.

Here’s a %
\raisebox{1em}{\hypertarget{id50}{}}\hyperlink{id49}{\textbf{\color{red}`hyperlink reference without a target`\_}}, which generates an
error.


\subsubsection{2.13.1   Duplicate Target Names%
  \label{duplicate-target-names}%
}

Duplicate names in section headers or other implicit targets will
generate “info” (level-1) system messages.  Duplicate names in
explicit targets will generate “warning” (level-2) system messages.


\subsubsection{2.13.2   Duplicate Target Names%
  \label{id21}%
}

Since there are two “Duplicate Target Names” section headers, we
cannot uniquely refer to either of them by name.  If we try to (like
this: %
\raisebox{1em}{\hypertarget{id52}{}}\hyperlink{id51}{\textbf{\color{red}`Duplicate Target Names`\_}}), an error is generated.


\subsection{2.14   Directives%
  \label{directives}%
}

\phantomsection\label{contents}
These are just a sample of the many reStructuredText Directives.  For
others, please see
\url{http://docutils.sourceforge.net/docs/ref/rst/directives.html}.


\subsubsection{2.14.1   Document Parts%
  \label{document-parts}%
}

An example of the “contents” directive can be seen above this section
(a local, untitled table of \hyperref[contents]{contents}) and at the beginning of the
document (a document-wide \hyperref[table-of-contents]{table of contents}).


\subsubsection{2.14.2   Images and Figures%
  \label{images-and-figures}%
}

An image directive (also clickable – a hyperlink reference):

\hyperref[directives]{\includegraphics{../../../docs/user/rst/images/title.png}}

Image with multiple IDs:

\includegraphics{../../../docs/user/rst/images/title.png}
\phantomsection\label{image-target-3}\label{image-target-2}\label{image-target-1}

A centered image:

\noindent\makebox[\linewidth][c]{\includegraphics{../../../docs/user/rst/images/biohazard.png}}

A left-aligned image:

\noindent{\includegraphics{../../../docs/user/rst/images/biohazard.png}\hfill}

This paragraph might flow around the image.
The specific behavior depends upon the style sheet and
the browser or rendering software used.

A right-aligned image:

\noindent{\hfill\includegraphics{../../../docs/user/rst/images/biohazard.png}}

This paragraph might flow around the image.
The specific behavior depends upon the style sheet and
the browser or rendering software used.

\subsubsection{2.14.4   Topics, Sidebars, and Rubrics%
  \label{topics-sidebars-and-rubrics}%
}

\emph{Sidebars} are like miniature, parallel documents.

\DUsidebar{
\DUtitle[title]{Sidebar Title}

\DUsubtitle[sidebar]{Optional Subtitle}

This is a sidebar.  It is for text outside the flow of the main
text.

\DUrubric{This is a rubric inside a sidebar}

Sidebars often appear beside the main text with a border and a different
background or font color.
}

A \emph{topic} is like a block quote with a title, or a self-contained section
with no subsections.

\begin{DUclass}{topic}
\begin{quote}
\DUtitle[topic]{Topic Title}

This is a topic.
\end{quote}
\end{DUclass}

A \emph{rubric} is like an informal heading that doesn’t correspond to the
document’s structure. It is typically highlighted in red (hence the name).

\DUrubric{This is a rubric}

Topics and rubrics can be used at places where a \hyperref[section-title]{section title} is not
allowed (e.g. inside a directive).

\subsubsection{2.14.7   Compound Paragraph%
  \label{compound-paragraph}%
}

The \emph{compound} directive is used to create a “compound paragraph”, which
is a single logical paragraph containing multiple physical body
elements. For example:

\begin{DUclass}{compound}
The ‘rm’ command is very dangerous.  If you are logged
in as root and enter
\begin{quote}
\begin{alltt}
cd /
rm -rf *
\end{alltt}
\end{quote}
you will erase the entire contents of your file system.
\end{DUclass}

Test the handling and display of compound paragraphs:

\begin{DUclass}{compound}
\begin{DUclass}{some-class}
Compound 2, paragraph 1,

compound 2, paragraph 2,
\begin{itemize}
\item list item 1,

\item list item 2,
\end{itemize}
compound 2, paragraph 3.
\end{DUclass}
\end{DUclass}

\begin{DUclass}{compound}
Compound 3, only consisting of one paragraph.
\end{DUclass}

\begin{DUclass}{compound}
\begin{quote}
\begin{alltt}
Compound 4.
This one starts with a literal block.
\end{alltt}
\end{quote}
Compound 4, paragraph following the literal block.
\end{DUclass}

Now something \emph{really} perverted – a nested compound block.  This is
just to test that it works at all; the results don’t have to be
meaningful.

\begin{DUclass}{compound}
Compound 5, block 1 (a paragraph).

\begin{DUclass}{compound}
Compound 6 is block 2 in compound 5.

Compound 6, another paragraph.
\end{DUclass}

Compound 5, block 3 (a paragraph).
\end{DUclass}

\begin{DUclass}{compound}
Compound 7, tests the inclusion of various block-level
elements in one logical paragraph. First a table,

\setlength{\DUtablewidth}{\linewidth}
\begin{longtable*}[c]{|p{0.249\DUtablewidth}|p{0.249\DUtablewidth}|p{0.249\DUtablewidth}|}
\hline

 & 
Middle cell,

paragraph.
 & 
Right cell.

Paragraph 2.

Paragraph 3.
 \\
\hline
\end{longtable*}
followed by a paragraph. This physical paragraph is
actually a continuation of the paragraph before the table. It is followed
by
\begin{quote}
a quote and
\end{quote}
\begin{enumerate}
\item an enumerated list,
\end{enumerate}
a paragraph,
\begin{DUoptionlist}
\item[--an]  option list,
\end{DUoptionlist}
a paragraph,
\begin{DUfieldlist}
\item[{a field:}]
list,
\end{DUfieldlist}
a paragraph,
\begin{description}
\item[{a definition}] \leavevmode

\end{description}
a paragraph, an image:
\includegraphics{../../../docs/user/rst/images/biohazard.png}
a paragraph,
\begin{DUlineblock}{0em}
\item[] a line
\item[] block,
\end{DUlineblock}
a paragraph followed by a comment,
% this is a comment
a paragraph, a

\DUadmonition[note]{

}
and the final paragraph of the compound 7.
\end{DUclass}


\subsubsection{2.14.8   Parsed Literal Blocks%
  \label{parsed-literal-blocks}%
}

\begin{quote}
{\ttfamily \raggedright \noindent
This~is~a~parsed~literal~block.\\
~~~~This~line~is~indented.~~The~next~line~is~blank.\\
~\\
Inline~markup~is~supported,~e.g.~\emph{emphasis},~\textbf{strong},~\texttt{literal\\

footnotes\DUfootnotemark{id22}{id8}{1},~%
\phantomsection\label{hyperlink-targets}hyperlink~targets,~and~\href{http://www.python.org/}{references}.
}
\end{quote}


\subsubsection{2.14.9   Code%
  \label{code}%
}

Blocks of source code can be set with the \DUroletitlereference{code} directive. If the code
language is specified, the content is parsed and tagged by the \href{http://pygments.org/}{Pygments}\DUfootnotemark{id34}{id33}{6}
syntax highlighter and can be formatted with a style sheet. (Code parsing
is turned off using the \texttt{syntax-highlight} config setting in the test
conversions in order to get identical results with/without installed
Pygments highlighter.)

\begin{DUclass}{code}
\begin{DUclass}{python}
\begin{quote}
\begin{alltt}
print 'This is Python code.'
\end{alltt}
\end{quote}
\end{DUclass}
\end{DUclass}

The \texttt{:number-lines:} option (with optional start value) generates line
numbers:

\begin{DUclass}{code}
\begin{DUclass}{python}
\begin{quote}
{\ttfamily \raggedright \noindent
\DUrole{ln}{~8~}\#~print~integers~from~0~to~9:\\
\DUrole{ln}{~9~}for~i~in~range(10):\\
\DUrole{ln}{10~}~~~~print~i
}
\end{quote}
\end{DUclass}
\end{DUclass}

For inline code snippets, there is the \DUroletitlereference{code} role, which can be used
directly (the code will not be parsed/tagged, as the language is not known)
or as base for special code roles, e.g. the LaTeX code in the next
paragraph.

Docutils uses LaTeX syntax for math directives and roles:
\texttt{\DUrole{code}{\DUrole{tex}{\textbackslash{}alpha = f(x)}}} prints $\alpha = f(x)$.

The \texttt{:code:} option of the \DUroletitlereference{include} directive sets the included content
as a code block, here the rst file \texttt{header\_footer.txt} with line numbers:

\begin{DUclass}{code}
\begin{DUclass}{rst}
\begin{quote}
{\ttfamily \raggedright \noindent
\DUrole{ln}{1~}..~header::~Document~header\\
\DUrole{ln}{2~}..~footer::~Document~footer
}
\end{quote}
\end{DUclass}
\end{DUclass}

\item A role with multiple class attributes, styled with raw directives:

\newcommand{\DUrolegreen}[1]{\textcolor{green}{#1}}
\newcommand{\DUrolesc}[1]{\textsc{#1}}

The following works in most browsers but does not validate

\DUrole{green}{\DUrole{sc}{\foreignlanguage{english}{British colourful text in small-caps}}}.
\end{itemize}


\subsection{2.22   Mathematics%
  \label{mathematics}%
}

Docutils supports inline math with the prefix or postfix \texttt{:math:}
role specificator, $n! + \sin(x_n^2)$ and $A_\text{c} =
\frac{\pi}{4} d^2$, as well as displayed math via the
\DUroletitlereference{math} directive:
%
\begin{equation*}
f(\epsilon) = \frac{1}{1 + \exp\left(\frac{\varepsilon}{k_\text{B}T}\right)}
\end{equation*}
Content may start on the first line of the directive, e.g.
%
\begin{equation*}
N = \frac{\text{number of apples}}{7}
\end{equation*}
Equations can be labeled with a reference name using the \texttt{:name:} option.
See \hyperref[eq-m]{eq:M} and \hyperref[eq-schrodinger]{eq:schrödinger} below.

The determinant of the matrix
%
\begin{equation*}
\mathbf{M} = \left(\begin{matrix}a&b\\c&d\end{matrix}\right)
\phantomsection
\label{eq-m}
\end{equation*}
is $|\mathbf{M}| = ad - bc$.

More than one display math block can be put in one math directive.
For example, the following sum and integral with limits:
%
\begin{equation*}
\int_0^1 x^n dx = \frac{1}{n + 1}
\end{equation*}%
\begin{equation*}
\sum_{n=1}^m n = \frac{m(m+1)}{2}
\end{equation*}
LaTeX-supported Unicode math symbols can be used in math roles and
directives:

The Schrödinger equation
%
\begin{equation*}
i\hbar \frac{\partial }{\partial t}\Psi  = \hat{H}\Psi ,
\phantomsection
\label{eq-schrodinger}
\end{equation*}
with the \emph{wave function} $\Psi $, describes how the quantum state of a
physical system changes in time.

\begin{itemize}
\item Role names and class arguments are converted to conform to the
regular expression \texttt{{[}a-z{]}{[}-a-z0-9{]}*} (letters are downcased,
accents and similar decoration is stripped, non-conforming
characters are replaced by a hyphen).

Class arguments may contain numbers and hyphens, which need special
treatment in LaTeX command names.

\DUrole{large}{\DUrole{custom4}{\DUrole{small-caps}{\DUrole{custom-role}{\DUrole{custom-role}{Text with role “custom4”}}}}} (but without styling by \texttt{DUrole*}
macros).

\item With LaTeX, roles can be styled within the document using the \DUroletitlereference{raw}
directive.

\newcommand{\DUrolelarge}[1]{{\large #1}}
\makeatletter
\@namedef{DUrolesmall-caps}{\textsc}
\@namedef{DUrolecustom4}{\textbf}
\makeatother

\DUrole{large}{\DUrole{custom4}{\DUrole{small-caps}{\DUrole{custom-role}{\DUrole{custom-role}{inline text}}}}} in large, bold, small-caps.

\item Custom roles can be based on standard roles:

This is a \emph{\DUrole{custom-emphasis}{customized emphasis text role}}

This is a \texttt{\DUrole{custom-literal}{customized literal text role}}

This is a \textbf{\DUrole{custom-strong}{customized strong text role}}

This is a \textsubscript{\DUrole{custom-subscript}{customized subscript text role}}

This is a \textsuperscript{\DUrole{custom-superscript}{customized superscript text role}}

This is a \DUroletitlereference{\DUrole{custom-title-reference}{customized title-reference text role}}
\end{itemize}


\subsection{3.2   class handling%
  \label{class-handling}%
}

This section tests class handling for block level elements by the LaTeX
writer. See the input file \texttt{classes\_latex.txt} for the raw LaTeX code used
to style the examples.

An “epigraph” directive is exported as “quote” wrapped in a “DUclass”
environment. Here, it is styled by a “DUCLASSepigraph” environment
redefining the “quote” environment as “minipage”:

\newcommand*{\DUCLASSepigraph}{%
  \renewenvironment{quote}{\vspace{1em}
                           \footnotesize\hfill{}%
                           \begin{minipage}{0.4\columnwidth}}%
                          {\end{minipage}\vskip\baselineskip}}

\begin{DUclass}{epigraph}
\begin{quote}
Do not play this piece fast. It is never right to play \emph{Ragtime} fast.
\nopagebreak

\raggedleft —Scott Joplin
\end{quote}
\end{DUclass}

Raw latex is also used to style the following lists: “DUCLASSenumerateitems”
redefines “itemize” as “enumerate”, “DUCLASSrules” draws horizontal lines
above and below.

\newcommand*{\DUCLASSenumerateitems}{%
  \renewenvironment{itemize}{\begin{enumerate}}%
                            {\end{enumerate}}%
}

\newenvironment{DUCLASSrules}%
               {\noindent\rule[0.5ex]{1\columnwidth}{1pt}}%
               {\noindent\rule[0.5ex]{1\columnwidth}{1pt}}

An “enumerated” bullet list:

\begin{DUclass}{enumerateitems}
\begin{itemize}
\item item

\item next item

\item third item
\end{itemize}
\end{DUclass}

A list with lines above and below:

\begin{DUclass}{rules}
\begin{itemize}
\item item

\item next item
\end{itemize}
\end{DUclass}

A normal bullet list is kept unchanged by the above redefinitions:

\begin{itemize}
\item item

\item next item

\item third item
\end{itemize}

A container wraps several elements in a common “class wrapper”. Here, we use
it to set 2 paragraphs and a list in small caps:

\newcommand*{\DUCLASSscshape}{\scshape}

\begin{DUclass}{scshape}

paragraph 1

paragraph 2

\begin{itemize}
\item bullet list

\item still bullet list
\end{itemize}
\end{DUclass}

A right-aligned line-block. Alignment handling is built into the latex
writer for image, table, and line block elements.

\begin{DUlineblock}{0em}
\raggedleft

\item[] Waldstr. 22

Tables with multi-paragraph multirow cells currently fail due to a LaTeX
limitation (see \url{https://sourceforge.net/p/docutils/bugs/225/}).

A table with multirow header and column-widths set by LaTeX:

\begin{longtable*}[c]{|l|l|}

\endlastfoot
\multicolumn{2}{|l|}{multicollumn cell} \\

\subsection{3.4   Option lists%
  \label{id23}%
}

The LaTeX-2e description environment is used for definition lists.
The definition is continued on the same line as the term, this should
not happen if a option-list is at the top of the definition.

If the option list is not at the first element in the definition, it
is contained in a quote

\begin{quote}
\begin{DUoptionlist}
\item[--help]  show help

\item[-v]  verbose
\end{DUoptionlist}
\end{quote}

\begin{description}

\subsection{3.7   Encoding special chars%
  \label{encoding-special-chars}%
}

The LaTeX Info pages lists under “2.18 Special Characters”

\begin{quote}
The following characters play a special role in LaTeX and are called
“special printing characters”, or simply “special characters”.

\begin{quote}
\# \$ \% \& \textasciitilde{} \_ \textasciicircum{} \textbackslash{} \{ \}
\end{quote}
\end{quote}

The special chars verbatim:

\begin{quote}
\begin{alltt}
# $ % & ~ _ ^ \textbackslash{} \{ \}
\end{alltt}
\end{quote}

However also \emph{square brackets} {[}{]} need special care.

\begin{quote}
Commands with optional arguments (e.g. \texttt{\textbackslash{}item}) check
if the token right after the macro name is an opening bracket.
In that case the contents between that bracket and the following
closing bracket on the same grouping level are taken as the
optional argument. What makes this unintuitive is the fact that
the square brackets aren’t grouping characters themselves, so in
your last example item{[}{[}…{]}{]} the optional argument consists of
{[}… (without the closing bracket).
\end{quote}

Compare the items in the following lists:

\begin{itemize}
\item simple item

\item {[}bracketed{]} item
\end{itemize}

\begin{description}
\item[{simple}] \leavevmode 
description term

\item[{{[}bracketed{]}}] \leavevmode 
description term

\end{description}

The OT1 font-encoding has different characters for the less-than,
greater-than and bar, < | >, except for typewriter font \DUroletitlereference{cmtt}:

\begin{quote}
\begin{alltt}
< | >

\subsection{3.8   Hyperlinks and -targets%
  \label{hyperlinks-and-targets}%

In LaTeX, we must set an explicit anchor (\texttt{\textbackslash{}phantomsection}) for a

\hyperref[image-label]{image label}.


\subsection{3.9   External references%
  \label{external-references}%
}

Long URLs should be wrapped in the PDF.
This can be achieved with the url command which is used by the LaTeX writer
whenever the content (name) of a reference node equals the link URL.

\begin{description}
\item[{Example:}] \leavevmode 
a long URL that should wrap in the output
\url{http://docutils.sourceforge.net/docs/user/latex.html\#id79}

\end{description}

If the argument contains any “\%”, “\#”, or “\textasciicircum{}\textasciicircum{}”, or ends with \texttt{\textbackslash{}}, it can’t
be used in the argument to another command. The argument must not contain
unbalanced braces.

The characters \textasciicircum{}, \{, \}, and \texttt{\textbackslash{}} are invalid in a “http:” or “ftp:” URL
and not recognized as part of it:

\begin{DUlineblock}{0em}
\item[] \url{http://www.example.org}/strange\textasciicircum{}\textasciicircum{}name
\item[] \url{http://www.example.org}\textbackslash{}using\textbackslash{}DOS\textbackslash{}paths\textbackslash{}
\item[] \url{http://www.example.org/XML}/strange\{n\}ame
\end{DUlineblock}

They can, however be used in paths and/or filenames.

Handling by the LaTeX writer:

\begin{itemize}
\item \texttt{\#}, \texttt{\textbackslash{}} and \texttt{\%} are escaped:

\begin{DUlineblock}{0em}
\item[] \href{http://www.w3.org/XML/Schema\#dev}{URL with \#}
\url{http://www.w3.org/XML/Schema\#dev}
\item[] \href{http://www.w3.org/XML/Schema\%dev}{URL with \%}
\url{http://example.org/Schema\%dev}
\item[] \href{A:DOS\\path\\}{file with DOS path}\DUfootnotemark{id44}{id43}{10} \url{A:DOS\\path\\}\DUfootnotemark{id45}{id43}{10}
\end{DUlineblock}

\DUadmonition[note]{
\DUtitle[note]{Note}

These URLs are typeset inside a LaTeX command without error.

\begin{DUlineblock}{0em}
\item[] \url{http://www.w3.org/XML/Schema\#dev}
\item[] \url{http://example.org/Schema\%dev}
\item[] \url{A:DOS\\path\\}\DUfootnotemark{id46}{id43}{10}
\end{DUlineblock}
}
\end{itemize}

\begin{itemize}
\item \textasciicircum{}\textasciicircum{} LaTeX’s special syntax for characters results in “strange” replacements
(both with href and url). A warning is given.

\href{../strange^^name}{file with \textasciicircum{}\textasciicircum{}}:
\url{../strange^^name}

\item Unbalanced braces, \{ or \}, will fail (both with href and url):

\begin{quote}
\begin{alltt}
`file with \{ <../strange\{name>`__
`<../strange\{name>`__
\end{alltt}
\end{quote}

while balanced braces are suported:

\begin{DUlineblock}{0em}
\item[] \url{../strange{n}ame}
\item[] \url{../st{r}ange{n}ame}
\item[] \url{../{st{r}ange{n}ame}}
