+\section{Abstract}
+
+|nodetree| is a development package that visualizes the structure of
+node lists. |nodetree| shows its debug informations in the console
+output when you compile a Lua\TeX{} file. It uses a similar visual
+representation for node lists as the UNIX |tree| command for a
+folder structure.
+
+Node lists are the main building blocks of each document generated by
+the \TeX{} engine \emph{Lua\TeX}. The package |nodetree| doesn‘t change
+the rendered document. The tree view can only be seen when using a
+terminal to generate the document.
+
+%-----------------------------------------------------------------------
+% Usage
+%-----------------------------------------------------------------------
+
+\section{Usage}
+
+The package |nodetree| can be used both with Lua\TeX{} and Lua\LaTeX{}.
+You have to use both engines in a text console. Run for example
+|luatex luatex-test.tex| to list the nodes using Lua\TeX{}.
+
+\begin{code}
+\input{nodetree.tex}
+\nodetreeregister{postline}
+
+Lorem ipsum dolor.
+\bye
+\end{code}
+
+Or run |lualatex lualatex-test.tex| to show a node tree using
+Lua\LaTeX{}. In Lua\LaTeX{} you can omit |\nodetreeregister{postline}|.
+|\usepackage{nodetree}| registers automatically the
+|post_linebreak_filter|. If you don’t want debug the
+|post_linebreak_filter| use |\nodetreeunregister{postline}|.
+
+\begin{code}
+\documentclass{article}
+\usepackage{nodetree}
+
+\begin{document}
+Lorem ipsum dolor.
+\end{document}
+\end{code}
+
+%%
+% inside Lua code
+%%
+
+\subsection{Debug nodes inside Lua code}
+
+Use the Lua function |nodetree.analyze(head)| to debug nodes inside your
+Lua code. The following code snippet demonstrates the usage in Lua\TeX{}.
+|head| is the current node.
+
+\begin{code}
+\input{nodetree.tex}
+
+\directlua{
+ local test = function (head)
+ nodetree.analyze(head)
+ end
+ callback.register('post_linebreak_filter', test)
+}
+
+Lorem ipsum dolor.
+\bye
+\end{code}
+
+This example illustrates how the function has to be applied in
+Lua\LaTeX{}.
+
+\begin{code}
+\documentclass{article}
+\usepackage{nodetree}
+
+\begin{document}
+
+\directlua{
+ local test = function (head)
+ nodetree.analyze(head)
+ end
+ luatexbase.add_to_callback('post_linebreak_filter', test, 'test')
+}
+
+Lorem ipsum dolor.
+\end{document}
+\end{code}

+
+\subsection{\cmd{\nodetreeregister}}
+
+\DescribeMacro{\nodetreeregister}
+\cmd{\nodetreeregister}\marg{callbacks}: The argument \marg{callbacks}

+\secref{sec:option-callback}.
+

+
+%%
+% \nodetreeset
+%%
+
+\subsection{\cmd{\nodetreeset}}
+
+\DescribeMacro{\nodetreeset}
+\cmd{\nodetreeset}\marg{kv-options}:
+This macro can only be used in Lua\LaTeX{}. \marg{kv-options} are key
+value pairs.
+
+\begin{code}
+\nodetreeset{color=no,callbacks={hpack,vpack},verbosity=2}

+
+\section{Options}
+\label{sec:options}
+
+%%
+% callback
+%%
+
+\subsection{Option \texttt{callback}}
+\label{sec:option-callback}
+
+The option |callback| is the most important setting of the package. You
+have to specify one alias to select the |callback|. Because of the
+underscores the callback name contains it can not set by its technical
+name (\rightarrow{} Figure \ref{fig:callback}).
+
+This macros process callback options:
+\cmd{\nodetreeregister}\marg{callbacks},
+\cmd{\nodetreeunregister}\marg{callbacks},
+\cmd{\nodetreeset}\marg{callback=<callbacks>} and
+\cmd{\usepackage}\oarg{callback=<callbacks>}\marg{nodetree}.
+
+Use commas to specify mulitple callbacks. Avoid using whitespaces:
+
+\begin{code}
+\nodetreeregister{preline,line,postline}
+\end{code}
+
+Wrap your callback aliases in curly braces for the macro |\nodetreeset|:
+
+\begin{code}
+\nodetreeset{callback={preline,line,postline}}
+\end{code}
+
+The same applies for the macro |\usepackage|:
+
+\begin{code}
+\usepackage{callback={preline,line,postline}}
+\end{code}

+%%
+% verbosity
+%%
+
+\subsection{Option \texttt{verbosity}}
+
+Higher integer values result in a more verbose output. The default value
+for this options is |1|. At the moment only verbosity level |2| is
+implemented.
+
+%%
+% color
+%%
+
+\subsection{Option \texttt{color}}
+
+The default option for |color| is |colored|. Use any other string (for
+example |none| or |no|) to disable the colored terminal output of the
+package.
+
+\begin{code}
+\usepackage[color=no]{nodetree}
+\end{code}
+
+%%
+% decimalplaces
+%%
+
+\subsection{Option \texttt{decimalplaces}}
+
+The options |decimalplaces| sets the number of decimal places for some
+node fields.
+
+\begin{code}
+\nodetreeoption[decimalplaces]{4}
+\end{code}
+
+gets
+
+\begin{code}
+├─GLYPH char: "a"; width: 5pt; height: 4.3055pt;
+\end{code}
+
+If |decimalplaces| is set to |0| only integer values are shown.
+
+\begin{code}
+├─GLYPH char: "a"; width: 5pt; height: 4pt;
+\end{code}
+
+%-----------------------------------------------------------------------
+%
+%-----------------------------------------------------------------------
+
+\section{Visual tree structure}
+
+\subsection{Two different connections}
+
+Nodes in Lua\TeX{} are connected. The |nodetree| package distinguishs
+between the |list| and |field| connections.
+
+\begin{itemize}
+ \item |list|: Nodes, which are double connected by |next| and
+ |previous| fields.
+ \item |field|: Connections to nodes by other fields than |next| and
+ |previous| fields, e. g. |head|, |pre|.
+\end{itemize}
+
+\subsection{Unicode characters to show the tree view}
+
+\renewcommand{\arraystretch}{1.5}
+
+The package |nodetree| uses the unicode box drawing symbols. Your
+default terminal font should contain this characters to obtain the tree
+view. Eight box drawing characters are necessary.
+
+\noindent
+\begin{tabular}{lcl}
+\textbf{Code} & \textbf{Character} & \textbf{Name} \\
+U+2500 & |─| & BOX DRAWINGS LIGHT HORIZONTAL \\
+U+2502 & |│| & BOX DRAWINGS LIGHT VERTICAL \\

+U+255A & |╚| & BOX DRAWINGS DOUBLE UP AND RIGHT \\
+U+2560 & |╠| & BOX DRAWINGS DOUBLE VERTICAL AND RIGHT \\
+\end{tabular}
+
+For |list| connections \emph{light} characters are shown.
+
+\begin{code}
+│ │
+│ ├─list1
+│ └─list2
+└─list3
+\end{code}
+
+|field| connections are visialized by \emph{Double} characters.
