% \begin{abstract}
% \noindent After several years the \lni{} bundle has been updated. The
% resulting new version fixes some long-standing bugs, solves problems and
% supports modern packages like \pkg{biblatex} and \pkg{microtype}. It has been
% put into one DTX file to make maintaining and distributing via CTAN a bit
% easier.
% \end{abstract}
%
% \section{Introduction}
% \LaTeX{} templates are often long-lasting. Even if they use meanwhile
% deprecated packages they are often passed from one generation of authors to
% the next.
%
% The Gesellschaft für Informatik~e.\,V. (GI) thankfully realized, that their
% bundle should be technologically
% modernized while the general layout remains the same.
%
% Based on the existing class and bib files I set-up a DTX file and started
% reworking the source code. Editors and authors suggested different additions
% and changes, which I tried to incorporate without changing the existing
% mechanisms too much.
%
% There is an additional package
% \href{https://github.com/gi-ev/biblatex-lni}{\pkg{biblatex-lni}} for an easy
% way of getting a correctly formed bibliography. This package is automatically used with v2.0 onwards.
% See \cref{sec:bibliography} for
% more information.
%
% \section{Installation}
% The \lni{} bundle is currently distributed via
% \href{https://github.com/gi-ev/LNI}{GitHub} and (preferably) \href{https://www.ctan.org/pkg/lni}{CTAN}.
% The later is the basis for all updates of the two main \TeX{} distributions
% \MiKTeX{} and \TeX{}~Live. Thus the easiest way to get all files needed to
% typeset an article for the \LNI{} is to use the package manager of your
% distribution.
%
% For a manual installation please call \texttt{pdflatex lni.dtx} at least
% twice and
% copy all resulting files (cls, tex and pdf) to your local TEXMF tree.
% Don't forget to update your file name database.
%
% \section{Usage}
% To use the predefined layout for a (German) submission to the \LNI{} just
% load the class file as usual with \cs{documentclass\{lni\}}.
%
% The class file loads a bunch of packages which are all part of modern \TeX{}
% distributions. Therefore, if you are confronted
% with a missing package, please try to download and install it using your
% distribution's package manager. Alternatively go to
% \href{http://www.ctan.org}{CTAN} to download missing packages.
%
% The \lni{} class can be used with \hologo{pdfLaTeX} as well as with
% \hologo{XeLaTeX} and \hologo{LuaLaTeX}. To achieve same results, the
% Type1-based packages \pkg{newtxtext}, \pkg{newtxmath} and \pkg{newtxtt}
% are used even for the unicode engines.
%
% \subsection{Options}\label{sec:options}
% Although the class file includes all layout information for a submission to
% the \LNI{}, there are options to adapt the output one way or another.
%
% \DescribeOption{english}A document loading the \lni{} class file uses German
% language adoptions by default. To switch to English, just load the class with
% option \opt{english}.
%
% The language influences not only the hyphenation patterns and terms used in
% the text, but also the choice of a corresponding \BibTeX{} file
% (cf.~\cref{sec:bibliography}).
%
% \DescribeOption{utf8 (deprecated in v1.8)}\DescribeOption{latin1 (deprecated in v1.8)}%
% \DescribeOption{applemac (deprecated in v1.8)}Although
% nowadays all major plattforms support and widely use UTF-8 encoding for
% text files, there might be some need to change the input encoding the
% \LaTeX{} document uses.
%
% This can be achieved by giving one of the options \opt{utf8} (which is the
% default), \opt{latin1} or \opt{applemac} to the document class. Using UTF-8
% is strongly recommended. Please note, that currently the bib file is supposed
% to use the same encoding.
%
% \DescribeOption{crop (new in v1.1)}%
% Option \opt{crop} gives you some crop marks (using the package \pkg{crop}) to
% better illustrate the final
% result of your article.
%
% \DescribeOption{nocleveref}When referencing figures, one has to type
% \texttt{Figure\textasciitilde}\cs{ref\marg{label}}. The package \pkg{cleveref}
% reduces the effort by offering the command \cs{cref\marg{label}}. This can be
% used with all floating objects. The package is loaded as default. In case it
% causes issues, one can disable it using with the \opt{nocleveref} option.
%
% \DescribeOption{nohyperref (deprecated in v1.8)}\pkg{hyperref} is used for colored hyperlinks
% within the articles. If you consider problems or just do not want that
% feature, you can disable it by using the option \opt{nohyperref}.
%
% \DescribeOption{nofonts (deprecated in v1.4)}On old systems
% you might not have installed the New TX fonts. If for whatever reason the
% \opt{oldfonts} option
% does not work for you, you can activate option \opt{nofonts}. This allows to
% suppress font loading completely using the engines standard fonts instead.
% Usually there should be no need to do so. Please note, that your output will
% differ from the publishers'.
%
% \DescribeOption{oldfonts (deprecated in v1.8)}On older systems you might not
% have installed the New TX fonts. Therefore option \opt{oldfonts} allows to
% to load the package \pkg{mathptmx} instead of the New TX fonts. The output
% will be in accordance to (or at least near) the publisher's requirements.
%
% \DescribeOption{norunningheads (deprecated in v1.8)}By default there are no more
% running headers from your document.
%
% \DescribeOption{runningheads (new in v1.8)}Editors can turn on the running headers
% using option \opt{runningheads}.
%
% \DescribeOption{anonymous (new in v1.8)}To easily anonymize a paper for
% blind review, use this option. Then all author information will be replaced
% with a placeholder. Additionally, there is a new macro \cs{anon\marg{hide in review}}
% which will be replaced with ``ANONYMIZED'' if the option is set.
% Also, \cs{anon\oarg{for review}\marg{for final version}} can be used that outputs ``for review''
% if the option is set, and ``for final version'' otherwise.
%
% \newpage
% \section{Setting up a document}
% You can use the file \file{lni-author-template.tex} as a starting point
% for setting up a document for submission. The \lni{} class uses the standard
% ways to build an article. A larger German example can be found in \file{lni-paper-example-de.tex}
%
% \subsection{Special meta comments}\label{sec:metadata}
% There is not just one \enquote{\TeX} and one \enquote{bibliography tool}, but
% many different ways to transform a .tex file into a PDF.
% Some \TeX{} editors like \texttt{TeXstudio}, \texttt{TeXmaker} and
% \texttt{TeXshop} support a special set of meta comments to give some
% information, how to deal with a concrete document.
%
% A typical example looks like:
% \begin{examplecode}
% % !TeX program = pdflatex
% % !BIB program = biber
% % !TeX encoding = UTF-8
% % !TeX spellcheck = en_US
% \documentclass[english]{lni}
% \end{examplecode}
%
% \subsection{Special macros for editors}
% \DescribeMacro{\startpage}\DescribeMacro{\editor}%
% \DescribeMacro{\booktitle\space(changed in v1.6)}%
% \DescribeMacro{\booksubtitle\space(new in v1.6)}%
% \DescribeMacro{\yearofpublication\space(new in v1.7)}In addition to the macros stated in
% \cref{sec:titlepage} for authors, there are special editor macros to
% influence the layout of the article:
% \begin{itemize}
% \item\cs{startpage} determines the starting page of the article. This
% should always be an odd (right) page.
% \item\cs{editor} states the name of the editor(s)
% \item\cs{booktitle} holds the name of a conference (optional argument for
% a short title used in the running headers)
% \item\cs{booksubtitle} holds an optional subtitle of a conference
% \item\cs{yearofpublication} can be used to set the year of publication
% \end{itemize}
%
% \subsection{Title page}\label{sec:titlepage}
% \DescribeMacro{\title}%
% \DescribeMacro{\subtitle\space(new in v1.1)}%
% The title of your work is given using the \cs{title} macro. In addition to
% the title itself, you can add a short title to be used
% in the header of a page:
% \begin{examplecode}[label={lst:title}]
% \title[Short title]{Title}
% \end{examplecode}
%
% You can also add a subtitle by \cs{subtitle\marg{subtitle}}.
%
% \DescribeMacro{\author}\DescribeMacro{\email}\DescribeMacro{\footnote\space(deprecated in v1.8)}%
% \DescribeMacro{\and\space(deprecated in v1.8)}\DescribeMacro{\affil}%
% The authors of an article are
% given using an extended \cs{author} macro, which holds not only the name, but also
% email adress and ORCID iD. Moreover the affiliation marker (number) is given as an optional
% argument. Affiliations are added with
% \cs{affil\oarg{number}\marg{information}} where you can use
% \texttt{\textbackslash\textbackslash} to split the address.
% \begin{examplecode}[label={lst:author}]
% \author[1,2]{Firstname1 Lastname1}{[email protected]}{0000-0000-0000-0000}
% \author[2]{Firstname2 Lastname2}{[email protected]}{0000-0000-0000-0000}
% \author[3]{Firstname3 Lastname3}{[email protected]}{0000-0000-0000-0000}
% \author[1]{Firstname4 Lastname4}{[email protected]}{0000-0000-0000-0000}%
% \affil[1]{Universität 1\\Abteilung\\Straße\\Postleitzahl Ort\\Land}
% \affil[2]{University 2 \\Department\\Address\\Country}
% \affil[3]{University 3\\Department\\Address\\Country}
% \end{examplecode}
%
% Leave the third and/or fourth argument empty if there is no email address and/or ORCID iD.
% Finally \cs{maketitle} will output the formatted title page.
%
% \DescribeMacro{\lnidoi\space(new in v1.2)}%
% LNI provides a DOI for each paper. In case, the DOI is known, it can be
% specified using the \cs{lnidoi} macro.
% \begin{examplecode}[label={lst:lnidoi}]
% \lnidoi{18.18420/se2016_01}
% \end{examplecode}
%
% Finally \cs{maketitle} will output the formatted title page.
%
% \subsection{Abstract and keywords}
% \DescribeEnv{abstract}\DescribeEnv{keywords}%
% \DescribeMacro{\and\space(new in v1.1)}%
% Each article should start with a short (70 to 150 words) abstract and some
% keywords. Please use the environments \env{abstract} and \env{keywords} for
% that purpose:
% \begin{examplecode}
% \begin{abstract}
% Tell the reader what your article is about
% \end{abstract}
% \begin{keywords}
% Give some keywords to categorize your article. You can use \and between two
% keywords to get the correct delimiter (comma plus space) automatically.
% \end{keywords}
% \end{examplecode}
%
% \subsection{Main text}
% \subsubsection{Headings}
% \DescribeMacro{\section}\DescribeMacro{\subsection}%
% \DescribeMacro{\subsubsection}
% You can use the standard macros \cs{section}, \cs{subsection}, \dots{} for
% sectioning your text.
%
% \subsubsection{Footnotes}
% \DescribeMacro{\footnote}%
% For adding a footnote, just use \cs{footnote\marg{footnote text}} where
% needed. Please note, that the footnote counter is automatically set to the
% correct value at the beginning of your text, i.\,e. it respects the number
% of affiliations given on the title page.
%
% \subsubsection{Lists}
% \DescribeEnv{itemize}\DescribeEnv{enumerate}%
% The \lni{} class redefines the standard lists environments \env{itemize} and
% \env{enumerate} to meet the requirements of the \LNI{}.
%
% Lists can be filled as usual by adding \cs{item} macros.
%
% \subsubsection{Floating objects}
% \DescribeEnv{figure}\DescribeEnv{table}%
% The environments \env{figure} and \env{table} can be used the standard way to
% include graphics or tables resp.
%
% However, please note, that the default placement parameters are changed to
% \opt{htbp} by the class \lni{}. If you need some local adjustment, please use
% the optional argument of both environments (cf.~Listing~\ref{lst:figure}).
%
% \DescribeMacro{\caption}\DescribeMacro{\label}
% A caption should be added by \cs{caption\marg{caption text}}, followed
% immediately by a \cs{label\marg{unique label}} entry.
% \begin{examplecode}[label={lst:figure}]
% \begin{figure}[tb]
% \includegraphics{...}
% \caption{...}
% \label{...}
% \end{figure}
% \end{examplecode}
%
% If you want to center floats, please \emph{do not} use the \env{center}
% environment, but the macro \cs{centering}, which does not add extra white
% space (cf.~Listing~\ref{lst:table}).
% \begin{examplecode}[label={lst:table}]
% \begin{table}
% \centering
% \begin{tabular}{lll}
% ...
% \end{tabular}
% \caption{...}
% \label{...}
% \end{table}
% \end{examplecode}
%
% \subsubsection{\texorpdfstring{Listings\,/\,Source code}%
% {Listings/Source code}}
% The \lni{} bundle loads the \pkg{verbatim} and \pkg{listings} package. While
% the former is there for compatability, the later is the standard way of
% integrating source code listings into a \LaTeX{} document.
%
% However, there are currently no config files shipped with the \lni{} bundle.
% Please consult the documentation for help on setting up \pkg{listings} for a
% specific programming language.
%
% \subsubsection{Math}
% For writing mathematics the package \pkg{amsmath} is already loaded by default.
% In addtion you can load e.g. \pkg{mathtools} for
% additional features. The \lni{} class offers by default the command
% \cs{powerset} to render the powerset symbol correctly as $\powerset$ and not
% as Weierstrass p ($\wp$).
%
% \subsubsection{Abbreviations and initialisms}
% \DescribeMacro{\eg}\DescribeMacro{\ie}\DescribeMacro{\cf}%
% \DescribeMacro{\etal}%
% To achieve consistent typesetting of common abbreviations, macros are
% predefined by the class. These macros should \emph{consistently} being used
% instead of writing the plain version. For example use \verb|\eg| rather than
% {\verb|e.g.,|}. The macros take care of spacing within and after the
% abbreviations.
% \begin{itemize}
% \item \cs{eg} for e.\,g.
% \item \cs{ie} for i.\,e.
% \item \cs{cf} for cf.
% \item \cs{etal} for et~al.
% \end{itemize}
%
% \DescribeMacro{\OMG}\DescribeMacro{\BPM}\DescribeMacro{\BPMN}\DescribeMacro{\UML}%
% In addition to common abbreviations, further initialisms are provided by the
% class for convenience and for a consistent visual appearance. Note that the
% class uses \textsc{smallcaps} for typesetting initialisms. The list of
% predefined initialisms comprises:
%
% \begin{itemize}
% \item \cs{OMG} for \textsc{omg} (Object Management Group).
% \item \cs{BPM} for \textsc{bpm} (Business Process Management).
% \item \cs{BPMN} for \textsc{bpmn} (Business Process Model and Notation).
% \item \cs{BPEL} for \textsc{bpel} (Business Process Execution Language).
% \item \cs{UML} for \textsc{uml} (Unified Modelling Language).
% \end{itemize}
%
% \DescribeMacro{\lniinitialism} You can add your own initialisms by stating
% \cs{lniinitialism\marg{\textbackslash initialism\_macro}\marg{text}} in the
% preamble.
%
% \subsection{Bibliography}\label{sec:bibliography}
% The \lni{} class uses BibLaTeX for and the
% \href{https://github.com/gi-ev/biblatex-lni}{\pkg{biblatex-lni}}.
% However, you have to add information on the bib
% file(s) in your preamble using \cs{addbibresource\marg{Bib file(s)}} and call
% \cs{printbibliography} where you want the bibliography to appear.
%
% Please note, that the \lni{} class sets
% \texttt{biber} as the default bibliography tool. \texttt{biber} is part of
% both major \TeX{} distributions and can easily be used within most \TeX{}
% editors, e.\,g. by using special meta data as described in
% \cref{sec:metadata}.
%
% If you want to pass settings to \pkg{biblatex} you can use a config
% file \texttt{biblatex.cfg}, for additional options please use the macro
% \cs{ExecuteBibliographyOptions}. Please consult the
% \href{http://texdoc.net/pkg/biblatex}{package's documentation} for
% more information.
% \begin{examplecode}
% % !TeX program = pdflatex
% % !BIB program = biber
% \documentclass{lni}
% ...
% \ExecuteBibliographyOptions{...}
% \addbibresource{FILENAME.bib}
% ...
% \begin{document}
