+Copyright (C) 2018 by Jonathan P. Spratte
+
+This package provides means to create duckified dummy contents. The following
+macros are available:
+
+ - `\duckument[key=val]` - print a short duckument
+ - `\blindduck[key=val]` - print a paragraph
+ - `\ducklist(*){environment}` - create a list of type `environment`
+ - `\ducklistlist(*){environment}` - create nested lists
+ - `\duckitemize` - `\ducklist{itemize}`
+ - `\duckenumerate` - `\ducklist{enumerate}`
+ - `\duckdescription` - `\ducklist{description}`
+ - `\duckumentsCreateExampleFile`
+ - `\duckumentsDrawRandomDucks`
+
+It also provides `example-image-duck.pdf` which contains several pages of random
+`tikzduck`s. Also `\includegraphics` is patched so one can use
+`\includegraphics{example-image-duck}` to in fact use a random duck out of
+`example-image-duck.pdf`. The behaviour of `\includegraphics` shouldn't be
+altered for other files.
+
+**Attention: At the moment, the package only works with pdfTeX and LuaTeX.**

+%
+% \section{Introduction}
+%
+% This package was inspired by the question
+% \href{https://tex.stackexchange.com/questions/419751}
+% {getting ducks in example images}.
+% It began on the idea to patch \cs{includegraphics} to automatically change its
+% behaviour if |example-image-duck| is used, but then it turned out to be a
+% simple alternative to the \pkg{blindtext} package.
+%
+% It is written as a docstrip file: executing |latex duckuments.dtx| generates
+% the \file{duckuments.sty} and \file{example-image-duck.tex} file and typesets
+% this duckumentation; execute |tex duckuments.dtx| to only generate the files
+% \file{duckuments.sty} and \file{example-image-duck.tex}.
+%
+% For its functionality \file{example-image-duck.tex} must be compiled at least
+% once. The sources are hosted on
+% \href{https://github.com/Skillmon/ltx_duckuments}{github}.
+%
+% \textbf{The package does currently only work on \pdfTeX\ and \LuaTeX}.
+%
+% \section{Duckumentation}
+%
+% \subsection{Dummy content}
+%
+% \begin{function}{\duckument}
+% \begin{syntax}
+% \cs{duckument}\oarg{key=value}
+% \end{syntax}
+% Produces a duckument with one sectioning entry of each level starting at
+% \cs{chapter} (if available) and two variants of the list environment
+% \env{itemize}, \env{enumerate}, and \env{description}, one only at top
+% level and one with 4~environments nested. The \meta{key=value}s accept every
+% key as explained in \autoref{sec:keys}, but not every key has an effect.
+% \end{function}
+%
+% \begin{function}{\blindduck}
+% \begin{syntax}
+% \cs{blindduck}\oarg{key=value}
+% \end{syntax}
+% Produces one paragraph of dummy content. The \meta{key=value}s accept every
+% key as explained in \autoref{sec:keys}, but not every key has an effect.
+% \end{function}
+%
+% \begin{function}{\ducklist}
+% \begin{syntax}
+% \cs{ducklist}\meta{*}\marg{environment}
+% \end{syntax}
+% Sets a list of the specified \meta{environment}, if \meta{*} is given
+% \cs{item}\oarg{dummy} is used instead of only \cs{item}. For |description|
+% the starred version is used automatically.
+% \end{function}
+%
+% \begin{function}{\ducklistlist}
+% \begin{syntax}
+% \cs{ducklistlist}\meta{*}\marg{list}
+% \end{syntax}
+% Sets 4~levels of a nested list of the specified \meta{environment}, if
+% \meta{*} is given \cs{item}\oarg{dummy} is used instead of only \cs{item}.
+% For |description| the starred version is used automatically.
+% \end{function}
+%
+% \begin{function}{\duckitemize}
+% Abbreviation for \cs{ducklist}|{itemize}|.
+% \end{function}
+%
+% \begin{function}{\duckenumerate}
+% Abbreviation for \cs{ducklist}|{enumerate}|.
+% \end{function}
+%
+% \begin{function}{\duckdescription}
+% Abbreviation for \cs{ducklist}|{description}|.
+% \end{function}
+%
+% \subsection{Other Macros}
+%
+% \begin{function}{\duckumentsCreateExampleFile}
+% Creates the file \file{example-image-duck.tex} in the current working
+% directory.
+% \end{function}
+%
+% \begin{function}{\duckumentsDrawRandomDucks}
+% Draws \cs{duckuments@randoms} random \pkg{tikzducks} using
+% \pkg{Ti\textit{k}Z}. Note that \pkg{duckuments} doesn't load
+% \pkg{Ti\textit{k}Z}, this macro is for the use in
+% \file{example-image-duck.tex}.
+% \end{function}
+%
+% \subsection{Patches}
+%
+% The package patches \cs{includegraphics} if it is defined at the time the
+% patch is applied (see \autoref{sec:keys}, |immediate|). The patch changes the
+% behaviour if |example-image-duck| is used. If that is the case, a random page
+% of that document is used. There shouldn't be any change in behaviour if other
+% files are used.
+%
+% The patch is done so that one can use \pkg{tikzducks} ducks without the need
+% of loading \pkg{tikz} in a minimal working duckument as example images.
+%
+% \subsection{Options}\label{sec:keys}
+%
+% The package and commands which take a \oarg{key=value} accept the following
+% options. Some of which only make sense as package options. The
+% \textbf{\texttt{bold}} printed value is the one used if you don't specify a
+% value.
+% \begin{options}
+% \item[toc=\textbf{true}$\vert$false]
+% If |true| the \cs{duckument} contains a ToC.
+% \item[maths=\textbf{both}$\vert$inline$\vert$display$\vert$none]
+% If |both| the \cs{blindduck} (which is also used by \cs{duckument})
+% contains both inline and displayed math. With |inline| and |display| the
+% respective maths is activated. |none| disables both.
+% \item[immediate=\textbf{true}$\vert$false]
+% If |true| \cs{includegraphics} is patched during package load time, else
+% the patching is done \cs{AtBeginDocument}.
+% \end{options}
+%
+% \end{documentation}
