-\section{Abstract}
-
-|nodetree| is a development package that visualizes the structure of
-node lists. |nodetree| shows its debug informations in the consoles’
-output when you compile a Lua\TeX{} file. It uses a similar visual
-representation for node lists as the UNIX |tree| command uses 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.
-
-|nodetree| is inspired by a
-\href{https://gist.github.com/pgundlach/556247}
-{gist from Patrick Gundlach}.
-
-%-----------------------------------------------------------------------
-% 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')
-}

-\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|:
