\chapter{Introduction}

This is an overview about how to write a large \LaTeX document
with multiple input sources, where:

\begin{itemize}
\item all sub-documents can be previewed by rendering only the partial document,
\item the forward/inverse search works,
\item SageTeX~\cite{sagetex} is supported,
\item formulas, graphics and the advanced KOMAscript package are enabled.
\end{itemize}

\chapter{Setup}

The general setup of this document is best explained by reading the header
of the ``\texttt{master.tex}'' file.

\section{Bibliography}

The bibliography uses \texttt{biblatex} and \texttt{biber},
which works much more robust than the older \texttt{bibtex}.
The file ``\texttt{bibliography.bib}'' defines the references
in the usual bibtex format,
and the references work across all sub-documents.
It also directly supports special characters. For example, the \cite{komascript} reference contains the letter ``ü'',
which is processed and rendered without any issues.

The next chapters are sub-documents.
They briefly describe each individual aspect in more detail.
