% \section{Introduction}\label{sec:doc-intro}
%
% The University of Passau does not provide a common thesis template
% to its students.
% For theses, written at the Chair of Software Engineering~II,
% many students chose between two templates that were provided by different
% people from the chair;
% other students chose from the large variety of templates available from the
% internet, causing each thesis looking differently.
%
% The author of this package provided a template,
% which he initially created for his bachelor's and master's thesis,
% that was recommended and used by many students.
% The implementation of that template, however, was very hacky and required
% some changes over time.
% This lead to the idea of creating a new template from scratch,
% that shall be used by all our students for their various types of theses,
% from bachelor to PhD level.
% The result is the \pkg{se2thesis} bundle.
%
% The bundle itself consists of several \LaTeX{} classes and packages
% that also allow reuse of various parts of it.
% Its main class is the \pkg{se2thesis} document class,
% an extension of the \KOMAScript{} |scrbook| document class.
% The packages \pkg{se2colors} and \pkg{se2fonts} provide necessary
% colour and font settings for the \pkg{se2thesis} class;
% the \pkg{se2packages} allows to load several recommended packages~(see
% \cref{sec:doc-se2packages}) with our recommended,
% predefined settings.
% They are available as separate packages, however, to allow their reuse for
% other classes, packages, and projects, as well.
%
% \subsection{Installation}\label{sec:doc-intro-install}
%
% The \pkg{se2thesis} bundle is available from \CTAN\footnote{
%   \href{https://ctan.org/pkg/se2thesis}{ctan.org/pkg/se2thesis}
% }.
% It is part of both \MiKTeX{} and \TeXLive.
% You can find its development version from GitHub\footnote{
%   \href{https://github.com/se2p/se2thesis}{github.com/se2p/se2thesis}
% }.
% The easiest way of installing it is through your \TeX{} distribution;
% please check your distribution's documentation on this.
% Note that it might be necessary to update your \TeX{} distribution
% because they might not provide you updates;
% for example, there is a new version of \TeXLive{} every year
% which needs to be installed separately.
% If you have installed an older version of \pkg{se2thesis}
% consider updating it to the latest version available from \CTAN{}
% through your distribution.
%
% For manual installation, we recommend to clone the Git repository
% and run the \texttt{l3build} tool that we also use for building the bundle.
% Running |l3build ctan| builds the source files and compiles the documentation.
% This creates a folder |build| containing these artefacts;
% |build/doc| contains the documentation,
% |build/local| the source files.
% See the documentation of \texttt{l3build} and your \TeX{} distribution
% on how to install them manually.
% Please note that \texttt{l3build} also provides a |l3build install| target
% to install the bundle files to your local texmf tree.
%
% The “Island of \TeX{}” project provides Docker images of \TeXLive\footnote{%
%   \href{https://islandoftex.gitlab.io/community/projects/docker/}{islandoftex.gitlab.io/community/projects/docker/}
% }.
% If you do not want to install/update \TeXLive{} on your system
% you might want to consider their \texttt{latest} image,
% which contains a recent \TeXLive{} 2023 build.
% They build their images weekly,
% thus also recent releases of \pkg{se2thesis} will be part of the image
% soon after their release date.
%
% \subsection{Availability on Overleaf}\label{sec:doc-intro-overleaf}
%
% Since April 3, 2024, the \pkg{se2thesis} document template is also available
% from Overleaf.  The document that is in Overleafs gallery is based on the
% example document that comes with this package.  Any Overleaf user can just
% create a new thesis document based on the template by clicking the respective
% button on Overleaf's gallery page.
%
% The gallery entry for \pkg{se2thesis} is available from
% \href{https://www.overleaf.com/latex/templates/se2thesis-a-thesis-class-for-the-chair-of-software-engineering-ii-at-the-university-of-passau-germany/fpymkmxmbgpc}{https://www.overleaf.com/latex/templates/se2thesis-a-thesis-class-for-the-chair-of-software-engineering-ii-at-the-university-of-passau-germany/fpymkmxmbgpc}.%
%
% \emph{Important remark:} Currently, the Overleaf template does not support
% \LuaLaTeX{} but requires builds with \pdfLaTeX.  The reason is that Overleaf
% does not yet ship \TeXLive~2024, but only \TeXLive~2023, which does not
% provide the respective font package~(notably \pkg{inconsolata-nerd-font}).
% Until the latest \TeXLive{} will be available from Overleaf, one can only use
% the \pdfLaTeX{} mode, which has some drawbacks on the fonts, but works fine
% otherwise.  From the Overleaf blog, we assume that \TeXLive~2024 might be
% available from some time in autumn 2024.  We will update this documentation
% accordingly, as soon as the new version is available.
%
% \subsection{General Macros}\label{sec:doc-intro-macros}
%
% They all have in common one macro, \cs{IfFormatAtLeastTF};
% this macro is part of the latest \LaTeX{} kernel.
% However, not all users might have upgraded their \TeX{} installation
% to a level using a recently-enough kernel version.
% Therefore, every class and package of this bundle will conditionally
% define the following macro:
%
% \begin{function}{\IfFormatAtLeastTF}
%   \begin{syntax}
%     \cmd{\IfFormatAtLeastTF} \marg{version} \marg{then block} \marg{else-block}
%   \end{syntax}
%   Checks whether the used \LaTeX{} format is at least the one from the
%   given date value.
%   The date needs to be specified either in YYYY/MM/DD or in YYYY-MM-DD
%   format.
% \end{function}
%
% \section{License}\label{sec:doc-license}
%
% Permission is granted to copy, distribute, and/or modify this software under
% the terms of the \LaTeX{} Project Public License~(LPPL), version~1.3c or
% later~(\href{https://www.latex-project.org/lppl.txt}{https://www.latex-project.org/lppl.txt}).
% The software has the status \enquote{maintained}.
%
% \section{The \cls{se2thesis} class}\label{sec:doc-se2thesis}
%
% The \cls{se2thesis} class is the central component of this bundle.
% It provides a wide variety of settings, mostly regarding the title page~(see
% \cref{sec:doc-se2thesis-title}) and the type area~(see
% \cref{sec:doc-se2thesis-typearea}).
%
% We aim to keep the \cls{se2thesis} class relatively small, especially
% considering packages that we load.
% Currently, the class itself loads the \pkg{se2colors}~(see
% \cref{sec:doc-se2colors}) and \pkg{se2fonts}~(see \cref{sec:doc-se2fonts})
% packages.
% The following packages and classes are loaded:
% \pkg{expl3}, \pkg{l3keys2e} in case one uses a \LaTeX{} kernel from before
% 2022--06--01, \pkg{graphicx}, \pkg{translations}, \KOMAScript, \pkg{xcolor},
% \pkg{ifthen}, as well as \pkg{fontspec}, \pkg{unicode-math},
% \pkg{inconsolata-nerd-font} and \pkg{libertinus-otf} if one uses \LuaTeX{};
% for \pdfLaTeX{} we load \pkg{fontenc}, \pkg{libertinus-type1}, and
% \pkg{inconsolata} instead of the latter three.
% Furthermore, we load \pkg{microtype};
% when using \LuaTeX{}, we also load \pkg{lua-widow-control} and \pkg{selnolig}.
%
% However, we recommend to use a couple of further packages, together with some
% further options to those package.  We describe these settings in
% \cref{sec:doc-se2packages}.
% Please consider looking at this section when starting to write your document.
%
% Before we start with a detailed documentation of the class, we explain one
% helper macro that can be used to check whether a package has been loaded.
% \begin{function}[pTF, updated = 2022-09-27]{\slcd_package_if_loaded:n}
%   \begin{syntax}
%     |\slcd_package_if_loaded:nTF| \Arg{package name} \Arg{true code} \Arg{false code}
%   \end{syntax}
%   Checks whether a package has been loaded and conditionally executes code.
% \end{function}
%
% \subsection{Load-time options}\label{sec:doc-se2thesis-options}
%
% The \pkg{se2thesis} class defines several load-time options, all of them
% optional, on top of the options provided by the \KOMAScript{} document
% classes.
% \begin{function}{class}
%   \begin{syntax}
%     |class| = \meta{choice}
%   \end{syntax}
%   Set the base document class.
%   Values are \cls{scrreprt} or \cls{scrbook}.
%   \emph{Note:} you cannot use \cls{scrartcl} because it does not provide
%   the required |chapter| sectioning.
%   Default is |scrbook|.
%
%   Please note that if you want to have the bibliography numbered or use an
%   appendix with alpha-numbering (A, B, \dots), you want to explicitly use
%   |scrreprt| as the base class; for some (currently unknown) reason this does
%   not work with the default |scrbook|.
% \end{function}
% \begin{function}{paper}
%   \begin{syntax}
%     |paper| = \meta{choice}
%   \end{syntax}
%   Set the paper format.
%   Possible values are |a4| or |b5|.
%   Default is |a4|.
% \end{function}
%
% \begin{function}{logofile}
%   \begin{syntax}
%     |logofile| = \marg{path-to-file}
%   \end{syntax}
%   Defines the path to the University's logo for the title page.
% \end{function}
%
% \begin{function}{thesistype}
%   \begin{syntax}
%     |thesistype| = \meta{choice}
%   \end{syntax}
%   Defines the type of the thesis.
%   Possible values are:
%   |bachelor| for a bachelor's thesis, |bachelorproposal| for a proposal to
%   a bachelor's thesis, |master| for a master's thesis, |masterproposal| for
%   a proposal to a master's thesis, |phdproposal| for a proposal to a PhD thesis,
%   |phd| for a PhD thesis in the natural sciences, |phdeng| for a PhD thesis
%   in engineering, and |phdphil| for a PhD thesis in natural philosophy.
% \end{function}
%
% \begin{function}{colormode}
%   \begin{syntax}
%     |colormode| = \meta{choice}
%   \end{syntax}
%   Select the color scheme used by the automatically loaded \pkg{se2colors}
%   package, see \cref{sec:doc-se2colors} for a description.
% \end{function}
%
%
% \subsection{The title page}\label{sec:doc-se2thesis-title}
%
% Designing a title package for a thesis can be complicated.
% There might be some requirements that are not obvious to the user, especially
% considering the positioning of elements.
% The University of Passau, for example, requires the logo to be positioned on
% the top right of a page;
% theses—especially PhD theses that shall be published through the University's
% library system—could be rejected from publication by the library until this is
% fixed.
%
% We thus redeclare the standard \cs{maketitle} macro from \KOMAScript{} and
% customise it to our needs.
% \begin{variable}{\@maketitle}
%   \begin{syntax}
%     \cmd{\@maketitle}
%   \end{syntax}
%   We override the definition of the \cmd{\@maketitle} macro for our needs.
% \end{variable}
% In addition to the macros provided by the \KOMAScript{} classes
% for the title-page values (e.g. \cs{author}, \cs{title},
% we provide some further macros that can be used.
% Setting values to these macros is optional in any case,
% if they are not set, the corresponding value is not put to the title page.
%
% \begin{function}{\version}
%   \begin{syntax}
%     \cmd{\version} \marg{version}
%   \end{syntax}
%   Specify the version of the document.  This can, for example, be a |git| hash
%   of the current version.
% \end{function}
%
% \begin{function}{\degreeprogramme}
%   \begin{syntax}
%     \cmd{\degreeprogramme} \marg{programme-name}
%   \end{syntax}
%   Specify the degree programme the thesis is meant to be accepted in.
%   Possible values are, among others, \enquote{Informatik} if you are writing
%   your thesis in German, or \enquote{Computer Science} if you are writing the
%   thesis in English.
% \end{function}
%
% \begin{function}{\matrnumber}
%   \begin{syntax}
%     \cmd{\matrnumber} \marg{matriculation-number}
%   \end{syntax}
%   Specify the matriculation number of the student writing the thesis.
%   This is required for bachelor's and master's theses.
% \end{function}
%
% \begin{function}{\supervisor, \cosupervisor}
%   \begin{syntax}
%     \cmd{\supervisor} \marg{name}
%     \cmd{\cosupervisor} \marg{name}
%   \end{syntax}
%   Specify the name of your supervisor and co-supervisor.
%   Both people usually are professors.
% \end{function}
%
% \begin{function}{\advisor, \coadvisor}
%   \begin{syntax}
%     \cmd{\advisor} \marg{name}
%     \cmd{\coadvisor} \marg{name}
%   \end{syntax}
%   Specify the name of your advisor and co-advisor.
%   Both people usually are PhD students or postdocs.
% \end{function}
%
% \begin{function}{\department, \institute}
%   \begin{syntax}
%     \cmd{\department} \marg{name}
%     \cmd{\institute} \oarg{short-name} \marg{name}
%   \end{syntax}
%   Specify the department and institute.
%   The department is, for example, \enquote{Faculty of Computer Science and
%   Mathematics}, the institute, for example, \enquote{Chair of Software
%   Engineering~II}.
%   If the \cs{department} value is not specify, we use \enquote{Faculty of
%   Computer Science} as the default value for English theses and
%   \enquote{Fakultät für Informatik und Mathematik} as the default value of
%   German theses.
% \end{function}
%
% \begin{function}{\external}
%   \begin{syntax}
%     \cmd{\external} \marg{name}
%   \end{syntax}
%   Specify the name of an external referee.
% \end{function}
%
% \begin{function}{\location}
%   \begin{syntax}
%     \cmd{\location} \marg{name-of-town}
%   \end{syntax}
%   Specify the name of your residence town for the signature field.
% \end{function}
%
% To define the path to the logo graphics we require a different workflow:
% We do not bundle logo graphics with this package due to legal restrictions.
% They can be downloaded from the University's website; please note that the
% website for downloading the logo graphics is only accessible from within the
% University's campus network or a VPN connection.
% To specify the path to the logo graphics, we provide a load-time option to the
% \cls{se2thesis} class called |logofile|~(see \cref{sec:doc-se2thesis-options}).
%
% When printing the thesis in two-side mode—which we recommend—the back of the
% title page again denotes author and title on the bottom.
% \begin{variable}{\@lowertitleback}
%   \begin{syntax}
%     \cmd{\l@lowertitleback}
%   \end{syntax}
%   Override this internal macro of \KOMAScript{} to print this information on
%   the back side of the title page.
% \end{variable}
%
% Additionally, we provide some interal rewritings to standard macros from
% \KOMAScript{} that allow to automatically split authors using the \cmd{\and}
% command.
% \begin{variable}{\author, \@author}
%   \begin{syntax}
%     \cmd{\author} \marg{author}
%   \end{syntax}
%   We rewrite the definitions of \cmd{\author} and \cmd{\@author} to do this
%   splitting automatically.
%   Additionally, this also adds a correctly translated version of \enquote{and}
%   between the author names if required.
% \end{variable}
%
% \subsection{Type-area settings}\label{sec:doc-se2thesis-typearea}
%
% The \cls{se2thesis} class manipulates the type area compared to the default
% settings of the \KOMAScript{} classes.
% Our settings are inspired by the \pkg{classicthesis} package, which itself is
% inspired by the style used by famous statistician Edward Tufte.
% We provide predefined settings for DIN-A4, DIN-A5, and DIN-B5 papers.
% If you need settings for other paper sizes, please open an issue on this
% package's GitHub repository
% (\href{https://github.com/se2p/se2thesis}{https://github.com/se2p/se2thesis})
% and we will happily include those settings in a future release of this bundle.
%
% Additionally, we are setting the page footer in a way that it contains the
% page numbers in the outer margin and the headmarks split from the page numbers
% by a vertical bar.
%
% \subsection{Abstract for the thesis}\label{sec:doc-se2thesis-abstract}
%
% Each thesis shall come with an abstract that summarises its content.
% The abstract should be written in the language the thesis is written in.
% Additionally, there is the requirement to provide a German abstract if the
% thesis is written in a foreign language.
% \begin{function}{\abstract}
%   \begin{syntax}
%     \cmd{\abstract}
%   \end{syntax}
%   We ensure that the \cmd{\abstract} command is defined for all document
%   classes.
% \end{function}
%
% \DescribeEnv{abstract}
% To typeset an abstract, we provide an environment called \env{abstract}.
% The environment takes an optional argument that specifies the language that is
% used in this abstract.
% Setting the abstract's language will cause its title to change to the
% respective language;
% additionally, hyphenation is also changed for that language.
% \begin{verbatim}
% \begin{abstract}[language]
%   Your abstract text.
% \end{abstract}
% \end{verbatim}
%
% \subsection{Acknowledgements}\label{sec:doc-se2thesis-acknowledgements}
%
% \DescribeEnv{acknowledgements}
% We provide the \env{acknowledgements} environment to typeset acknowledgements
% for your thesis.
% Using this environment is optional.
% Usually, bachelor's and master's thesis do not contain such an acknowledgements
% section, however, there is no general rule to this.
% \begin{verbatim}
% \begin{acknowledgements}[language]
%   Your acknowledgements.
% \end{acknowledgements}
% \end{verbatim}
%
% \subsection{Document structuring}\label{sec:doc-se2thesis-structuring}
%
% A larger work, such as a thesis, is usually structured in three large blocks:
% a frontmatter that provides all the overview, such as abstract, table of
% contents, etc.,
% a mainmatter that contains all the actual content,
% and a backmatter for appendices.
% \cls{se2thesis} ensures that the following macros are defined because they are
% not provided by all \KOMAScript{} classes.
% \begin{function}{\frontmatter, \mainmatter, \backmatter}
%   \begin{syntax}
%     \cmd{\frontmatter}
%     \cmd{\mainmatter}
%     \cmd{\backmatter}
%   \end{syntax}
%   Switches between frontmatter, mainmatter, and backmatter.
%   Most notably, the frontmatter will have roman page numbers, while the other
%   two will have arabic page numbers.
% \end{function}
%
% \subsection{Authorship declaration}\label{sec:doc-se2thesis-authorship}
%
% The University of Passau requires its students to provide an authorship
% declaration as part of their thesis for submission.
% They provide a template form, which would not fit the style of the
% \cls{se2thesis} class.
% Thus, we provide the \cmd{\authorshipDeclaration} macro to typeset such
% a declaration.
% It uses the original~(German) text of the declaration and fills in the values
% that are specified by the \cmd{\author} and \cmd{\location} macros.
% \begin{function}{\authorshipDeclaration}
%   \begin{syntax}
%     \cmd{\authorshipDeclaration}
%   \end{syntax}
%   Print the authorship declaration text.
% \end{function}
% \emph{Please note:} the authorship declaration will always be printed in
% German, no matter what the language of the thesis is.
% This happens due to legal requirements.
% In order to make this work, you have to load the \pkg{babel} or
% \pkg{polyglossia} package in a way that it also supports German hyphenation.
% For example, use
% \begin{verbatim}
% \usepackage[ngerman,main=UKenglish]{babel}
% \end{verbatim}
% for a thesis with \emph{traditional English}\footnote{
%   there is a nice, probably photoshopped, picture of a Steam setup dialogue
%   stating that American English is a \enquote{simplified version} of British
%   English, see
%   \href{https://jakubmarian.com/is-american-english-simplified-and-british-english-traditional/}{https://jakubmarian.com/is-american-english-simplified-and-british-english-traditional/}.
% } as its main language and support for German.
%
% \begin{function}{\signatureBox}
%   \begin{syntax}
%     \cmd{\signatureBox} \oarg{width} \marg{signature-name}
%   \end{syntax}
%   A helper macro to print the signature box for the authorship declaration.
%   The optional argument \oarg{width} allows to specify a custom width for the
%   signature line.
%   The default is 5\,cm.
%   The mandatory argument \marg{signature-name} specifies the name of the
%   signee, which will be typeset below the signature line.
% \end{function}
%
% \subsection{Research Questions and findings summaries}\label{sec:doc-se2thesis-summaries}
%
% Most theses written at our Chair will require the student to provide some
% empirical evaluation of their work to shed insights whether their proposed
% ideas are actually useful.
% For an empirical study, one needs to specify research questions and maybe also
% hypotheses.
% The \cls{se2thesis} class supports this by providing environments for this.
%
% \DescribeEnv{resq}
% The \env{resq} environment shall be used to specify a research question.
%
% \DescribeEnv{hyp}
% The \env{hyp} environment shall be used to specify a hypothesis.
%
% \DescribeEnv{summary}
% After describing the results, we recommend to give an explicit summary of the
% findings for a research question or hypothesis.
% This summary shall be given in one or two sentences.
% The \env{summary} environment provides a convenient way for this;
% it will be typeset in a highlighted box that is easy to spot and also allows
% readers of the work to quickly grasp the main findings.
% \begin{verbatim}
% \begin{summary}{label-reference}
%   The summary text itself.
% \end{summary}
% \end{verbatim}
% The environment expects as a parameter a label, for example, to a research
% question;
% however, this can also be arbitrary text.
%
% \subsection{Language Support and Hyphenation}\label{sec:doct-se2thesis-lang}
%
% The study regulations of the University of Passau require students to write
% their thesis in either German or English.  For both cases it is recommended
% to load a package for the correct hyphenation patters.  Usually, one can
% either choose between the \pkg{babel} and \pkg{polyglossia} package.  For a
% detailed discussion in the differences and which to choose, please use the
% search engine of your choice.
%
% For this documentation we stick with the \pkg{babel} package, which is often
% considered to be the standard package.
%
% If you write your thesis in German, load \pkg{babel} in your preamble like
% follows
% \begin{verbatim}
% \usepackage[ngerman]{babel}  
% \end{verbatim}
% For a thesis in English, you have to also load the German variant plus the
% English one as the default (see \cref{sec:doc-se2thesis-authorship} for an
% explanation)
% \begin{verbatim}
% \usepackage[ngerman,main=UKenglish]{babel} 
% \end{verbatim}
%
% Note that by default, \LaTeX{} does not provide hyphenation for compound
% words, which is explained in the \TeX{} Book~\cite[p.~454]{Knu86} and a
% StackExchange post\footnote{\href{https://tex.stackexchange.com/a/63234/14622}{https://tex.stackexchange.com/a/63234/14622}}.  The \pkg{babel} package
% provides a way (called shorthands) for German, which allows to reenable
% hyphenation for compound words (as they are common on German).  These
% shorthands are by default not available for English, but they can easily be
% added by adding
% \begin{verbatim}
% \useshorthands{"}
% \addto\extrasUKenglish{\languageshorthands{ngerman}}
% \end{verbatim}
% after loading \pkg{babel} with the aforementioned \cmd{\usepackage}
% macro\footnote{see https://tex.stackexchange.com/a/298844/14622}.
%
% \emph{Please note:} loading the \pkg{hyphenat} package is strongly discouraged
% by the \pkg{se2thesis} maintainer because it conflicts with the \env{hyp}
% environment provided by \pkg{se2thesis} (see \cref{sec:doc-se2thesis-summaries}).
