In LaTeX, literal blocks can be customized with the \textquotedbl{}literal-block-env\textquotedbl{}
setting. This test file exists to check if the LaTeX writer output compiles
and looks as expected.

Start with a plain literal block:

\begin{quote}
\begin{alltt}
$\textbackslash{}sin^2(x)$ and $\textbackslash{}cos^2(x)$ equals one:

\textbackslash{}[
   \textbackslash{}sin^2(x) + \textbackslash{}cos^2(x) = 1 % for all x
\textbackslash{}]
\end{alltt}
\end{quote}

A latex \textquotedbl{}code-block\textquotedbl{} (set with \textquotedbl{}literal-block-env\textquotedbl{}, if syntax
highlight is \textquotedbl{}none\textquotedbl{}):

\begin{DUclass}{code}
\begin{DUclass}{latex}
\begin{quote}
\begin{alltt}
$\textbackslash{}sin^2(x)$ and $\textbackslash{}cos^2(x)$ equals one:

\textbackslash{}[
   \textbackslash{}sin^2(x) + \textbackslash{}cos^2(x) = 1 % for all x
\textbackslash{}]
\end{alltt}
\end{quote}
\end{DUclass}
\end{DUclass}

A literal block in a table:

\setlength{\DUtablewidth}{\linewidth}%
\begin{longtable*}{|p{0.063\DUtablewidth}|p{0.145\DUtablewidth}|p{0.063\DUtablewidth}|}
\hline

test
 & 
\begin{minipage}{8\ttemwidth}
\begin{alltt}
\textbackslash{}sin^2 x
\end{alltt}
\end{minipage}
 & 
test
 \\
\hline
\end{longtable*}

A literal block in a table with auto-width columns:

\begin{longtable*}{|l|l|l|}
\hline
test & 
\ttfamily\raggedright
\textbackslash{}sin\textasciicircum{}2~x
 & test \\
\hline
\end{longtable*}

\begin{DUclass}{note}
\begin{DUadmonition}
\DUtitle{Note}

A literal block in an admonition:

\begin{quote}
\begin{alltt}
\textbackslash{}sin^2 x
\end{alltt}
\end{quote}
\end{DUadmonition}
\end{DUclass}

\DUsidebar{
\DUtitle{Literal Block in a Sidebar}

\begin{quote}
\ttfamily\raggedright
\textbackslash{}sin\textasciicircum{}2~x
\end{quote}
}

Parsed literal block with inline markup and leading whitespace:
