%
% \begin{abstract}
%   The TUDa-CI-Bundle provides a possibility to use the Corporate Design of TU Darmstadt with \LaTeX.
%   Therefore, it contains document classes as well as some helper packages and config files together with some templates for user documentation.
%   Up to Version 4.00 the documentation was only included in the demo files.
%   This document now sums up all features and includes references to other package documentations if required.
%
%   This process is not yet finished and will probably last some more time.
%   So there will be more documentation as soon as possible and we try to gather everything within this document.
%   There are possibilities to help with the documentation especially the translation of the descriptions already aailable in German.
%   In case you want to help feel free to provide a pull-request via the GitHub repository or contact the author for other options of contributing.
% \end{abstract}
%
% \tableofcontents
%
% \chapter{Contents of the TUDa-CI Bundle}
% The TUDa-CI Bundle currently contains template files for the following document types:
%
% \begin{description}
%   \item[Print publications] generic document class which provides modes for more specific documents.
%         The basic documentation applies to all types and can be found in \autoref{sec:tudapub}.
%         \begin{itemize}
%           \item \file{DEMO-TUDaPub.tex}: default document matching the CI guideline
%           \item minimal Template for internal reports \file{DEMO-TUDaReport.tex} using \option{type=intern} (see description of \option{type} in \autoref{sec:options} on \pageref{option:type})
%           \item (PhD) theses, using \option{type=thesis}. This also extends the functionality and adds some thesis specific mechanisms, see \autoref{sec:theses} \file{DEMO-TUDaThesis.tex} and \file{DEMO-TUDaPhD.tex}
%         \end{itemize}
%   \item[Scientific Posters] based on the \pkg{tcolorbox} poster library, \cite{TUDaSciPoster}
%   \item[Presentation Slides] beamer theme. This includes the old design of 2008 as well as the redesign of 2023,  \cite{TUDaBeamer}
%   \item[Announcement Posters] for event or job announcements, \cite{TUDaPoster}
%   \item[Leaflets]  \cite{TUDaLeaflet}
%   \item[Exercise Sheets/Exams] \cite{TUDaExercise}
%   \item[Letters] \cite{TUDaLetter}
% \end{description}
%
% The document classes use internal auxiliary packages to simplify the usage and reduce the maintenance effort.
% These are called by the elements they define:
% \pkg{tudacolors}, \pkg{tudafonts}, \pkg{tudarules} as well as the \pkg{pgfplots} color schemes defined by \pkg{tuda-pgfplots}.
%
% Additionally, the setup is defined to support department specific configuration files.
% Officially we currently only support the setup of the department of mechanical engineering, see \autoref{sec:mecheng}.
% There may be unofficial custom setups within the departments.
% Those are not officially supported.
% In case you want to provide your own and add it to TUDa-CI, please have a look at \autoref{sec:department-config}.
%
% \chapter{Getting Started}
% The TUDa-CI bundle is available via CTAN\cite{ctan-tuda-ci} and therefore no manual installation should be required.
% For TUDa members the HRZ also provides an on-premise Overleaf instance which also contains a release including all necessary files.
% In case you are a member of TU Darmstadt you can access the server via \url{https://sharelatex.tu-darmstadt.de/}.
%
% \section{Logo installation}
% Sadly the logo files may not be published together with this template.
% So it is necessary to either disable the loading or install the files.
% The easiest way to do so is by placing a copy of the required logos in your working directory.
% But this will be required for every document you want to use these templates for.
%
% A better alternative would be a local installation of the logo file.
% This can be done by moving the file info your \verb+TEXMFHOME+ directory.
% On standard \TeX{} Live Installations this would be called \path{texmf/} in your users home directory.
% Inside this one the logo files have to be placed according to the TDS (\TeX{} Directory Structure), which means it has to be copied into
% \path{texmf/tex/latex/tuda-ci-logos}.
%
% Alternatively there are scripts to be run inside a terminal to automatically detect the correct location.
% These can be found inside the \path{tools} directory of TUDa-CI's GitHub Repository (\citeurl{tuda-ci-github}).
%
% \chapter{\cls{tudapub} â€“ generic class for articles and theses}
% \label{sec:tudapub}
% The TUDa-CI bundle uses a generic document class to be more flexible with the layout adjustments.
% The setup is based on \KOMAScript and this section is listing the features.
% Afterwards there will be specific information on the thesis modes.
%
% \section{Usage and class options}

% The class is loaded using
% \begin{Syntax}
% \documentclass[|\meta{Options}|]{tudapub}
% \end{Syntax}
% \noindent TUDa-CI defines some  additional options to be used. These are described below.
% The shown default values apply only for the document class itself. The template files may use different settings.
% An overview of these differences are shown in \autoref{tab:demo-options}.
%
% \DescribeKeyOption{class=article/report/book}{article}
% This option selects the base document class.
% The values load the corresponding \KOMAScript class  \cite{scrguide-en}.
% The article value thus loads \cls{scrartcl}.
%
% \KOMAScript is a collection of classes and packages for \LaTeX{} which, in addition to the typographical adaptations to the European area, also greatly extends the configuration options.
% The documentation is also available in German \cite{scrguide-de}.
%
% \DescribeKeyOption{accentcolor=\meta{Color}}{0b}*
% Selects the spot color for use within the identity bar. In addition to these colors, any defined can be used.
% See \autoref{sec:color} for the list of predefined colors as well as additional options for a more detailed selection.
% The Options \option{accentcolor}, \option{textaccentcolor} and \option{identbarcolor} will be passed to tudacolors.
% Using those, the colors can even be set independently of each other.
%
% \DescribeKeyOption{custommargins=\meta{Boolean}/geometry}{false}
% According to the corporate design, the line lengths are too long from a typographical point of view.
% This is why the custommargins class option exists.
% Details are described within \autoref{sec:margins}.
%
% \DescribeKeyOption{marginpar=true/false/auto}{auto}
% Controlls the marginpar. The default setting is auto.
% This means that the marginpar column runs across the fifth column of the layout grid \cite{TUDaGuideline}.
%^^A\marginpar{Marginpar example}
% Above this, the option also accepts boolean values. False would set width of the column to 0.
% The mechanism itself is not deactivated.
%
% The font inside the marginpars are controlled using the komafont mechanism \cite{scrguide-en} using the \code{marginpar} element.
% It is defined as
% \begin{example}
% \setkomafont{marginpar}{\accentfont}
% \end{example}
% to extend this setting, e.\,g. by adding a color one can add
% \begin{example}
% \addtokomafont{marginpar}{\color{textaccentcolor}}
% \end{example}
% to the preamble.
%^^A \marginline{
%^^A \includegraphics[width=\marginparwidth]{example-image}\\
%^^A Marginpar example using ragged text made with \KOMAScript's marginline
%^^A }
%
% \DescribeKeyOption{twocolumn=\meta{Boolean}}{false}*
% Activates the two-column mode globally.
% In this case, however, two margin columns are created due to their nature.
% Use in combination with \code{marginpar=auto} is therefore questionable in most cases.
% If the two-column mode is only activated locally, that behavior does not apply, but the margin notes are deactivated.
%
% \DescribeKeyOption{ruledheaders=all/none/chapter/section}{all}
% Selects the style of the headings.
% \code{ruledheaders=all} selects the style framed with rules for all up to \cs{subsubsection}.
% This style is limited accordingly for chapter or section.
% False loads the \KOMAScript{} default setup instead.
%
% \DescribeKeyOption{title=default/small}{default}
% The relatively large font size of the title can lead to spacing issues, especially with long titles for theses.
% The \code{title} option prevents this by loading the font sizes set defined for the paper 1 size smaller (e.\,g. a5 font size if a4 paper is used).
%
% \DescribeKeyOption{type=publication/thesis/intern}{publication}
% \label{option:type}%
% Is used to load specific configuration for theses (\autoref{sec:thesis}) or internal documents (\autoref{sec:report}).
%
% \DescribeKeyOption{headline=true/false/automark}{false}
% The CI guideline \cite{TUDaGuideline} allows headers to be used ruled below the identbar.
% That may be confusing as the headers are typeset larger than subsection headings.
% Because of that it's switched off by default, but users can enable this setting using the \code{headline} option.
% \code{automark} will also be passed to \pkg{scrlayer-scrpage} and switch to running headers.
%
% \DescribeKeyOption{logo=head/body}{body}
% Sets the position of the logo on the title page, see \autoref{sec:title-options}.
%
% \DescribeKeyOption{colorback=true/false/title/body/head}{true}
% Change the color setup of the title page, see \autoref{sec:title-options}.
%
% \DescribeKeyOption{IMRAD=\meta{Boolean}}{true}*
% Toggles the check for IMRAD labels, see \autoref{sec:IMRAD}.
%
% \DescribeKeyOption{logofile=\meta{file name/path}}{tuda\_logo}*
% Allows an alternative logo to be used.
% This option is available so that the templates can also be used without the TUDa logo.
% The logos are reserved to be used by TUDa members and may therefore not be published with this template.
% In case you want to install the logo files locally you can find further information at \citeurl{TUDa-CI-Info}.
%
% \noindent Additionally all \KOMAScript{} options can be used. These are described within the documentation. Some more notes on the interaction between \KOMAScript{} and TUDa-CI can be found in \autoref{sec:KOMA}.
%
% \section{Title}\label{sec:title}
%
% The title page is generated automatically by \cls{tudapub}.
% The structure for this corresponds largely to the classic method using \cs{maketitle}.
%
% The \KOMAScript{} option \code{titlepage}\cite{scrguide-en} is supported to switch between separate title pages and an in-page title block.
% Due to the implementation, \code{titlepage=true} is treated identically to \code{titlepage=\allowbreak firstiscover}.
%
% \DescribeMacro{\titlehead}\DescribeMacro{\title}\DescribeMacro{\subtitle}\DescribeMacro{\subject}\DescribeMacro{\author}\DescribeMacro{\and}\DescribeMacro{\thanks}\DescribeMacro{\date}\DescribeMacro{\publishers}
% These macros are used to set the title data.
% If not mentioned differently all need one mandatory argument which contains the data.
% 	They are used as with standard \LaTeX{}, but there were a few added to support the additional features of the title page design.
% \begin{Syntax}
% \title{|\meta{title}|}
% \author{|\meta{Author1}|\thanks{Affiliation of Author1} \and |\meta{Author2}|}
% % |\textnormal{[â€¦other elementsâ€¦]}|
% \maketitle
% \end{Syntax}
%
% \subsection{TUDa-CI specific title elements}
% \DescribeMacro{\titlegraphic}
% Accepts any \LaTeX{} content, does not have to be an image.
% This is placed flush with the top corner in the main part of the title page.
% This macro is usually used to place a graphic:
% \begin{example}
% \titlegraphic{\includegraphics[width=\width]{example-image}}
% \end{example}
% \DescribeMacro{\width}\DescribeMacro{\height}
% \cs{width} and \cs{height} can be used to select the appropriate size of the image.
% From version 3.19, there also is a starred variant \cs{titlegraphic*}.
% With this, scaling and any necessary cropping to fill the reserved area is done automatically using \pkg{trimclip}.
% \begin{example}
% \titlegraphic*{\includegraphics{example-image}}
% \end{example}
%
% \DescribeMacro{\addTitleBox}%
% \DescribeMacro{\addTitleBoxLogo}
% \begin{Syntax}
% \addTitleBox{|\meta{Box Content}|}
% \addTitleBoxLogo*{|\meta{Logo}|}
% \end{Syntax}
% The TUDa CI design is using white boxes to place additional Information or logos on the title page.
% These can be added using \cs{addTitleBox} or \cs{addTitleBoxLogo}.
%
% All title boxes are placed below each other with a specified distance and use a white background.
% Text or an institute logo may appear here. The background hast to be white.
%
% Whereas \cs{addTitleBox} will set the box to the same width and horizontal alignment as the TUDa logo the logo variants of this macro don't have a fixed width.
% Here the default is to place scale the logo automtically and maual scaling has to be enforced using the starred variant:
%
% \begin{example}
% \addTitleBox{Text, e.\,g. Institute}
% \addTitleBoxLogo{example-image}
% \addTitleBoxLogo*{\includegraphics[width=.3\linewidth]{example-image}}
% \end{example}
%
% \DescribeMacro{\AddSponsor}
% As of version 3.0, the sponsor mechanism of \cls{tudaleaflet} is also available in \cls{tudapub}.
% This makes it possible to place sponsor logos below the title graphic.
% Sponsor logos or names can be added using \cs{AddSponsor}
% \begin{Syntax}
% \AddSponsor{|\meta{Code to insert the Logo or just the name}|}
% \end{Syntax}
% \DescribeMacro{\height} \cs{height} is defined within the argument.
% All sponsors added this way are aligned at their baseline.
% This can be used to scale multiple logos to the same height.
% The space between the sponsors will be horizontally filled.
%
% \DescribeMacro{\sponsors}
% The second variant enables manual placement with vertical alignment, as may be necessary for logos with different heights.
% In this case, only the spacing and seperation rules are added around the logos:
% \begin{Syntax}
% \sponsors{|\meta{logo1}\meta{logo2}|}
% \end{Syntax}
%
% For theses there exist additional data fields \cs{birthplace}, \cs{group}, \cs{examdate}, \cs{submissiondate}, \cs{tuprints}, \cs{urn} and \cs{reviewer}.
% To use these and also learn about other specials of the title mechanism within theses, please refer to \autoref{sec:theses-title}.
%
% \subsection{Options for titlepage modification}
% \label{sec:title-options}
% \DescribeKeyOption{logo=head/body}{body}
% The position of the logo can be switched. This is done via the class option \option{logo};
% \begin{description}
%   \item[logo=head]
%         The logo is placed in the header directly next to the title, which is reduced in width.
%         The background of the title is colored in the color of the identity bar.
%         This setting also will move the boxes below the logo to the page head.
%
%   \item[logo=body] The logo including the info boxes is placed in the body of the front page.
% \end{description}
%
% \DescribeKeyOption{colorback=\meta{Boolean}/title/head/body}{true}
% Similar to the logo position the color structure can be adjusted.
% \option{colorback} toggles between the colored block on the title page and the white background.
%
% The other values will enable the colored area but allow switching between positions.
% \begin{description}
%   \item[colorback=title] Only the title background (without subtitle) is colored.
%   \item[colorback=head] Background of the total title block including subtitles is colored.
%   \item[colorback=body] Only the background of the area used for the \cs{titlegraphic} is colored.
% \end{description}
%
% \subsection{Extra title material for theses}
% For \option{mode=thesis} the title page works a little different.
% Here some data elements are used to provide an interface to be overwritten and are prefilled using additional data fields.
% The fields only existing in \option{thesis} mode are:  \cs{birthplace}, \cs{group}, \cs{examdate}, \cs{submissiondate}, \cs{tuprints}, \cs{urn} and \cs{reviewer}.
% For more information on their use and other settings for theses have a look at \autoref{sec:theses}.
%
% \subsection{Abstract}
% \cls{tudapub} extends the availability of the \environment{abstract} environment to \cls{scrbook}.
% Additionally, it adds an optional argument to select the language.
% This should be used to use multiple abstracts of different languages within one document.
%
% \begin{example}
% \begin{abstract}
%   Abstract using the document main language (here English)
% \end{abstract}
%
% \begin{abstract}[german]
%   Weitere Zusammenfassung in einer anderen Sprache (hier Deutsch),
%   sofern benÃ¶tigt.
% \end{abstract}
% \end{example}
%
% It is important that all languages used in the document are loaded.
% In the case of the example, both options, \option{english} and \option{german} must be passed to the babel package.
%
% \section{PDF/A}
%
% The university library requires submissions to be compliant to the PDF/A standard.
% \DescribeKeyOption{pdfa=\meta{Boolean}}{true}
% The TUDaPub class supports the PDF/A 2b standard.
% PDF/A mode is automatically activated within \cls{tudapub}.
% Depending on the document it's using an implementation via the \pkg{pdfx} package or the \LaTeX{} kernels own PDF management.
%
% \LaTeX{} is not validating the file in any way, it is just using compatible settings for all elements processed by the compiler.
% As \LaTeX{} is not doing any processing on image files the user has to ensure the font settings match the requirements for PDF/A.
%
% \DescribeKeyOption{pdfx=\meta{Boolean}}{true}
% \cls{tudapub} will try to automatically select the best method.
% This is done using \option{pdfx} option.
% This should only be toggled manually if the user is totally sure to understand the impact.
%
% \subsection{Creating PDF/A using the PDF management}
% \label{sec:pdfmanagement}
% The template files which use PDF/A by default now include the settings for the PDF management:
% \begin{example}
% \DocumentMetadata{
%   pdfstandard=a-2b,
%   pdfversion=1.7,
%   lang=en,% or de or â€¦
% }
% \end{example}
% This can also be used within other documents. More Information on this structure can be found in the documentation of the \pkg{pdfmangement-testphase} \cite{pdfmanagement-testphase} as well as \pkg{l3pdfmeta} \cite{l3pdfmeta}.
%
% If this setting is used \cls{tudapub} will automatically disable the loading for \pkg{pdfx}.
% \cls{tudapub} will automatically try to pass the title data to the metadata.
% In case the title contains more complex material which can not be expanded into text it's possible to overwrite these settings using \pkg{hyperref}'s \cs{hypersetup}.
% The demo files include examples.
%
% \subsection{Creating PDF/A using the pdfx}
% In older versions of this bundle we used \pkg{pdfx} to create PDF/A compliant output files.
% If the PDF management using \cs{DocumentMetadata} is not detected to be active, \cls{tudapub} will still try to use this mechanism.
% The metadata setup for the XMP data then works completely different.
%
% The compiler is creating an additional \file{\cs{jobname}.xmpdata} file.
% It is tried to insert the title data directly.  The title data is usually transferred directly.
% However, this can lead to problems if there are macros used within title material.
% For example, the subtitle for this document contains the \LaTeX{} macro, but only text elements can be used.
% Similar to the link labels within the PDF bookmarks.
%
% \DescribeMacro{\Metadata}To avoid this issue, \cls{tudapub} provides the macro \cs{Metadata}.
% All variables that can be processed by \pkg{pdfx} can be set here according to the key=value structure.
% \begin{example}
% \Metadata{
%   author=Marei Peischl (peiTeX),
%   title=LaTeX im Corporate Design der TU Darmstadt,
% }
% \end{example}
% Please note that this macro only works if PDF/A output is activated, and no PDF management is used.
% If this is not the case, \cls{tudapub} issues a corresponding error message or warning.
%
% For a full list of the available metadata fields have a look at the \pkg{pdfx} documentation \cite{pdfx}.
%
% \subsection{Additional metadata as requested by the university library}
% \label{sec:IMRAD}
% There is a  mechanism for identifying the IMRaD \cite{imrad} structuring model.
% In the style of the individual sub-areas, the call of
% \begin{example}
% \IMRADlabel{introduction}
% \IMRADlabel{methods}
% \IMRADlabel{results}
% \IMRADlabel{discussion}
% \end{example}
% would generate the corresponding labels.
% They have the name \codefont{IMRAD:\meta{key}}.
%
% \DescribeKeyOption{IMRAD=\meta{boolean}}{true}*
% The check mechanism is activated by default at the request of the library.
% If you are not planning to use these labels or this structure just don't match your document, the warning can be deactivated using the \option{IMRAD=false}.
%
% \subsection{Colors conversion and profile}
% \label{sec:pdfa-color}
% PDF/A can only use one color model within a document.
% By default, if no specific profile is selected TUDa-CI will convert the colors to RGB.
% However, as there is no clear conversion, CMYK elements should not be used in \option{pdfa=true} mode.
%
% This mode is not suitable for print output.
% There will be a warning if the conversion is triggered.
% To use CMYK colors with PDF/A it's necessary to use PDF/A via the PDF management (\autoref{sec:pdfmanagement}) and select a specific color profile \cite[see][]{l3pdfmeta}.
%
% \section{(PhD) Theses â€“ Special options and elements used in these templates}
% \label{sec:theses}
%
% As mentioned before the these templates \file{DEMO-TUDaThesis} and \file{DEMO-TUDaPhD} are based on \cls{tudapub}.
% Therefore, they support all options as described before but provide some additional mechanisms.
% To load the thesis specific config the option \option{type=thesis} has to be used.
% As there are additional thesis specific options it's also possible to use the \option{thesis} key directly and add the specific options within braces:
%
% \begin{example}
% \documentclass[
% english,
% class=report,
% thesis={type=master}
% |[â€¦]|
% ]{tudapub}
% \end{example}
%
% \DescribeKeyOption{thesis/type=bachelor/pp/master/dr/drfinal/\meta{text}}{initially unset}*
% Selection of the type.
% This is printed on the title page and also selects which data is mandatory.
% Possible values are listed below including their impact. The items in parentheses list the required data for that type.
% \begin{description}
%   \item[sta] \enquote{Studienarbeit}: Student research project. (\cs{title}, \cs{author}, \cs{date})
%   \item[bachelor] \enquote{Bachelor thesis}. (\cs{title}, \cs{author}, \cs{submissiondate}, \cs{department}, \cs{reviewer})
%   \item[master] \enquote{Master thesis}. (\cs{title}, \cs{author}, \cs{submissiondate}, \cs{department}, \cs{reviewer})
%   \item[pp] \enquote{Project proposal}. (\cs{title}, \cs{author}, \cs{date}, \cs{department})
%   \item[dr] submitted Doctoral thesis (\cs{title}, \cs{author}, \cs{submissiondate}, \cs{department}, \cs{reviewer})
%   \item[drfinal] accepted Doctoral thesis (\cs{title}, \cs{author}, \cs{submissiondate}, \cs{examdate}, \cs{department}, \cs{reviewer})
% \end{description}
% If a type is specified that was not listed the text is directly used as type.
% In this case, there are no mandatory title fields except the title.
%
% \DescribeKeyOption{dr=rernat/rerpol/ing/phil}{initially unset}
% Loads one of the predefined texts for the title page.
%
% For example, the value phil would use:
% \foreignquote{german}{Zur Erlangung des Grades eines Doktor der Philosophie (Dr.\,phil.)}
% Please be aware that the titlepage is enforced to use German.
%
% \DescribeMacro{\drtext}If none of these values correspond to the desired title, a text can be transferred directly.
% \begin{example}
% \drtext{To obtain the degree â€¦}
% \end{example}
%
%
% \DescribeKeyOption{department=\meta{shorthand or text}}{initially unset}
% The departments are permanently stored as text modules in German and English.
% This option enables selection as a document class option.
% For compatibility reasons, however, the department macro can also be used for this.
% The following shorthands are predefined:
%
% \begin{tabular}{@{}l@{${}\to{}$}l@{}}
%   arch &amp; Architecture \\
%   bauing &amp; Civil and environmental engineering               \\
%   bio    &amp; Biology                                           \\
%   chem   &amp; Chemistry                                         \\

%   wi     &amp; Law and Economics
% \end{tabular}
%
% In addition to the departments, there are also \enquote{fields or study}.
% These are not available for doctoral theses.
% If the given value is not found in the departments the fields of study will be checked afterwards.
% The study areas have the following shorthands:
%
% \begin{tabular}{@{}l@{${}\to{}$}l@{}}
%   ce &amp; Computational Engineering \\
%   ese   &amp; Energy Science and Engineering  \\
%   ist   &amp; Information Systems Engineering \\
%   mech  &amp; Mechanics                       \\
%   metro &amp; Mechatronics
% \end{tabular}
%
% If anything other than one of these shorthands is found, the provided text is used directly and a corresponding warning is issued.
%
% \subsection{Thesis specific title page settings and customization}
% \label{sec:theses-title}
% \DescribeKeyOption{instbox=\meta{Boolean}}{true}*
% Selecting the department also creates a box on the title page below the logo.
% In some cases this setting does not match the requirements.
% Therefore, the option \option{instbox} can be deactivated.
%
% \DescribeKeyOption{ignore-missing-data=\meta{Boolean}}{false}
% This option is a switch that makes it possible to disable the error message about title data that has not been transferred.
% In this case, only a warning is created if the specified data does not match the requirements.
%
% \DescribeMacro{\publishers}
% Is used here for the location and is preset with \foreignquote{german}{Darmstadt} or \foreignquote{german}{Darmstadt, Technische UniversitÃ¤t Darmstadt} (for PhD theses).
%
% \DescribeMacro{\subject}
% Will be placed below the \cs{subtitle} as for the normal title page, but will hold all the additional information which can be provided using the  data fields described in this section.
%
% \DescribeMacro{\birthplace} Place of birth.
% \DescribeMacro{\department}
% Subject/field of study. It's preferred to set it via the class option.
% However, the argument is processed in the same way.
% This macro also provides the functionality of specifying entries that differ from the default entries.
% Especially if a different text to the default \enquote{in the department of} and its variants is required.
% For this purpose, \cs{department} provides an optional argument:
% \begin{Syntax}
% \department[|\meta{replacement text}|]{|\meta{abbreviation/name}|}
% \end{Syntax}
% In addition, from version 2.01 there is also the option of replacing the entire text \enquote{in the department \meta{department name}} as well as the information in the info box on the title page. This is done using the starred variant:
% \begin{example}
% \department*[text for the box]{text between type and author}
% \end{example}
% \DescribeMacro{\examdate}% \DescribeMacro{\submissiondate} Will be added within the description block \cs{subject}.
%
% \DescribeMacro{\institution}\DescribeMacro{\department}\DescribeMacro{\institute}\DescribeMacro{\group}
% Will be added inside a title box as was described in \autoref{sec:title} below each other.
%
% \DescribeMacro{\reviewer} Reviewers.
% Multiple reviewers are separated by \cs{and} as for authors.
% The numbering runs from left to right.
%
% \minisec{Adjusting the reviewer labels}
% The identifier can be changed using an optional argument:
% \begin{Syntax}
% \reviewer[|\meta{replacement identifier}|]{|\meta{name1}| \and |\meta{name2}|}
% \end{Syntax}
% To change the numerical designation, a comma list is used instead of a single label:
% \begin{example}
% \reviewer*[identifier1, identifier2]{name1 \and name2}
% \end{example}
% In this case, the automatic numbering before the identifier is omitted.
% If, for example, the wording of the doctoral regulations is to be complied with, the following applies:
% \begin{example}
% \reviewer[Erstreferent\_in,Koreferent\_in]{Name1 \and Name2}
% \end{example}
%
% \DescribeMacro{\setupReviewName}There is also a macro for creating department-specific templates.
% This allows changes to be made without calling \cs{reviewer}.
% \begin{Syntax}
% \setupReviewName{|\meta{Alternative label to replace \enquote{Review}}|}
% \setupReviewName[1]{|\meta{Erstreferent}|}
% \setupReviewName*{|\meta{label1}|,|\meta{label2}|}
% \end{Syntax}
%
% \DescribeKeyOption{reviewer-on-uppertitleback=\meta{Boolean}}{false}*
% As of version 3.26, the reviewers are no longer named on the back of the title page.
% This can be controlled using the thesis option \option{reviewer-on-uppertitleback}.
%
% \DescribeMacro{\studentID} Matriculation number. According to the template specifications, this information is always optional.
%
% \DescribeMacro{\titleintro}\DescribeMacro{\titleaddendum} From version 2.03, these hooks can be used to add any text directly in front or after the automatic generated subject block holding the thesis data.
%
% \DescribeMacro{\tuprints}\label{page:tuprints}  Publication via TUprints requires this setting.
% The data should be provided by the TUprints submission process.
% \begin{example}
% \tuprints{
%   printid=12345,
%   urn=123456,
%   year=2022
% }
% \end{example}
%
% \DescribeKeyOption{printid=\meta{TUprints print ID}}{\meta{initially unset}}*
% \DescribeKeyOption{urn=\meta{TUprints URN}}{\meta{initially unset}}*
% If the argument does not contain an equals sign, the value is set as \option{printid} and no \option{urn} is specified.
%
% \option{printid} is the ID number of the TUprints entry and will be used automatically to create a hyperlink to the corresponding DOI. %%^^A\issue 505
% The URN is â€“ in addition to the DOI â€“ a permanently unique resource identifier for the document.
% In TUprints, the number corresponds to the \option{printid} with the addition of a check digit.
% Both dates can be found in the details of the TUprints entry.
%
% \minisec{License information}
% \DescribeKeyOption{license=\meta{License key or license text}}{cc-by-4.0}*
% From version 3.08 there are predefined values for \option{license} simplify customization. These are as follows:
%
% \parbox[t]{.5\linewidth}{%
%   \codefamily
%   \href{https://creativecommons.org/licenses/by/4.0/}{cc-by-4.0} \textnormal{default since version 4.0}\par

%   \href{https://creativecommons.org/licenses/by-nc-nd/2.0/}{cc-by-nc-nd-2.0-en}\par
% }
%
% The introduction of this option was part of the preparation for adapting the standard license.
% The corresponding discussion can be found at \url{https://github.com/tudace/tuda_latex_templates/issues/251}.
% The adjustment of the default setting for TUDa-CI was made with version 4.0.
%
% The ULB of TUDa offers support in choosing a suitable Creative Commons license at \url{https://www.ulb.tu-darmstadt.de/dpub} or the CC project itself via its license finder at \url{http://creativecommons.org/choose/}.
% TU Darmstadt recommends use of the open CC BY 4.0 license in its Publication Guidelines and Open Access Policy.
%
% If a value different from the keys listed above is found, this value is used directly in place of the license text.
% If it itself contains an equals signs or commas, grouping is necessary.
%
% \subsection{Affidavit}
% \DescribeMacro{\affidavit}
% The macro \cs{affidavit} creates a declaration of authorship with a signature line.
% The name/signature could be set via options or the Information provided with \cs{author} is used.
% In the demo documents, the affidavit is located directly after the title.
%
% \DescribeKeyOption{hide-architecture-note=\meta{Boolean}}{false}*
% The class option \option{hide-architecture-note} allows to disable the note specifically tagetting theses of the architecture department.
% For compatibility reasons it's false by default. So the note will be printed.
% It's also possible to set this directly as an affidavit option if it's not a PhD theses.
%
% \minisec{Disclaimer:}
% The \cs{affidavit} command is using the current version (as of 2025-01-22) of the text provided at
% {\small\url{https://www.tu-darmstadt.de/studieren/studierende_tu/studienorganisation_und_tucan/hilfe_und_faq/artikel_details_de_en_37824.de.jsp}}.
%
% According to the department II, the legally binding text can always be found there.
% The docx file should be used, printed out, signed, scanned and then integrated.
% The easiest way to do this is to use the pdfpages package.
% Please ensure to check which regulations apply to your thesis before submission.
% TUDa-CI can not ensure the text is up to date or matches your submission type.
%
% From version 3.32, the distinction between an affidavit for digital or printed submissions, which has been supported since version 3.06, no longer applies.
% For compatibility reasons, the options are still available, but have the same effect.
% It is imperative that students check whether the text corresponds to the required version before submitting a thesis.
%
% PhD theses use a different text here; the affidavit option \option{affidavit=dr} is used internally to differentiate between them.
%
% Version 3.20 also allows the transfer of further options for the signature name, a signature image or the location.
% The extent to which these options may be used must be clarified by the user before submission.
% TUDa-CI cannot make a reliable statement on this.
% \begin{example}
% \affidavit[
%   signature=Signature name,
%   signature-image={\includegraphics[width=\width]{signatureimage}}
% ]
% \end{example}
% A vertical shift of the signature image is not implemented directly, but is easily possible by using the \LaTeX macro \cs{raisebox}\marg{shift}\marg{content}.
%
% It is also possible to print an affidavit in another language as a supplement.
% In order to handle the structure and any necessary language switching, there is an environment:
% \begin{Syntax}
% \begin{affidavit*}[|\meta{Babel language option}]|{|\meta{heading}|}
%   \meta{Text}
% \end{affidavit*}
% \end{Syntax}
% This version deliberately does not have a signature line, as the developers do not consider this version to be legally binding.
% However, the environment can also be used for special forms of explanation.
% In this case, an additional signature line can be added:
% \DescribeMacro{\AffidavitSignature}\DescribeKeyOption{signature-location=\meta{Location}}{Darmstadt}*
% \begin{Syntax}
% \AffidavitSignature[|\meta{city}|]
% \end{Syntax}
%
%
% \section{Further configuration options}
%
% \subsection{Select the color model}
% Color vision depends on the way colors are presented.
% For professional printing there usually is a color profile required by the printer to be used.
% For use in documents, it is therefore important to know which output medium is to be used primarily.
% Technically, this difference is reflected in color mixing models.
% In accordance with the guidelines, TUDa-CI supports both a color model for print output (cmyk) and for screen display (RGB).
% The implementation is done via the \pkg{xcolor} package, whereby the corresponding color values for both models are stored withing \pkg{tudacolors}.
%
% Normally, TUDa-CI automatically selects a suitable model.
% The default setting of \option{pdfa=true} ensures a conversion to RGB (vgl.~\ref{sec:pdfa-color}) if no manual setting was found.
%
% If a specific color profile should be used, the \pkg{xcolor} options \option{cmyk} or \option{RGB} can be transmitted directly to \cls{tudapub}.
% They are passed on to the package and will be processed according to the \pkg{xcolor} documentation \cite{xcolor}.
%
% \section{Customizations that deviate from the corporate design guidelines}
%
% \subsection{Font size}
% \DescribeKeyOption{fontsize=\meta{length}}{9pt}
% Contrary to the corporate design guidelines, \cls{tudapub} can also process other font sizes.
% The \option{fontsize} option of \KOMAScript is supported (e.\,g. \option{fontsize=11pt}).
% If no special font size configuration file is available for TUDa-CI, the file supplied with KOMA- Script is selected.
% Examples of deviations for typographical reasons are also shown in the demo files for theses.
%
% \subsection{Margins}
% \label{sec:margins}
% \DescribeKeyOption{custommargins=true/false/geometry}{false}
% According to the corporate design, the line lengths are too long from a typographical point of view.
% This is why the \option{custommargins} class option exists.
%
% \begin{description}
%   \item[custommargins=false]
%         Default setting of \cls{tudapub}.
%         The margins correspond to the specifications of the Corporate Design Guidelines \cite{TUDaGuideline}.
%         The setting is made using \pkg{geometry}.
%         Customizations are overwritten by executing \cs{maketitle}.
%         To allow personal adjustments one of the other settings is required.
%
%   \item[custommargins=true] The settings of the Corporate Design Guidelines are not activated.
%         pkg{geometry} is not loaded.
%         This mode corresponds to the default setting of \KOMAScript.
%         The margins are not explicitly defined, but calculated on the basis of the typearea package \cite[see][]{scrguide-en}.
%
%   \item[custommargins=geometry]
%         This variant was created based on user requests.
%         It allows using \cls{tudapub} with support for manual adjustments.
%         \pkg{geometry} is loaded and preconfigured as with \option{custommargins=false}.
%         However, it is possible to make minor adjustments by using the \cs{geometry} command.
%         The settings that apply at the start of the document are saved and restored after the title pages.
%
%         Please note that the settings use the preset type area as a starting point (with or without a margin column, depending on the option).
%         It is possible to reset all options before adding your own:
%         \begin{Syntax}
%         \geometry{
%           reset,
%           |\meta{Adjustments starting from geometry's defaults}|
%         }
%         \end{Syntax}
%         This applies in particular to the options \code{includehead}, \code{includefoot} and \code{includemp}.
% \end{description}
%
% \minisec{Remark on the headers/footers}
% If the option \option{marginpar=true} remains set, the header and footer protrude beyond the margin column.
% For aesthetic reasons, it is therefore recommended in this case to limit the header and footer to the text area with \option{marginpar=false}.
%
% The standard layout of the column titles is also not very advantageous, as the column titles can be locally larger than the actual headline. (\option{headline=automark})
%
% For this reason, \cls{tudapub} provides a simpler page style, which considerably simplifies use with living column titles.
% The structure is realized using \pkg{scrlayer-scrpage} and can be adapted according to the \KOMAScript documentation \cite{scrguide-en}.
% \begin{example}
% \pagestyle{TUDa.headings}
% \end{example}
%
% \minisec{Remark on binding correction}
% \DescribeKeyOption{BCOR=\meta{length}}{0pt}
% \DescribeKeyOption{BCORtitlepage=\meta{Boolean}}{false}
% If a binding correction (\option{BCOR=\meta{length}}) is used, this is not automatically inserted on the title page.
% For this case, the \option{BCORtitlepage} option was added with version 3.0. If this is activated, the title page uses the value of the \pkg{typearea} option \option{BCOR} on the first page as an addition to the left margin.
%
% \subsection{Frontmatter/Mainmatter/Backmatter}
% The macros \cs{frontmatter}, \cs{mainmatter} and \cs{backmatter} are usually only available for the class \cls{scrbook}.
% On request, these macros have also been provided as a basis for \cls{scrartcl} and \cls{scrreprt}.
% It is therefore possible to switch to Roman numerals for the opening credits.
% Arabic numerals are then used from \cs{mainmatter}.
%
% \subsection{Math fonts}
% As there is no compiler-independent universal math font and the corporate design guidelines do not take any recommendations into account, several possible variants were discussed.
% The default setting always corresponds to the installation standard.
% No specific settings are loaded.
% The discussion on this can be found at:
% \url{https://github.com/tudace/tuda_latex_templates/issues/19}
%
% A few example configurations are shown below.
% In principle, however, the math type is freely selectable â€“ apart from the restrictions of the compiler.
% In many cases, the \enquote{\TeX{} Font Catalogue} is helpful for selection and use: \url{https://tug.org/FontCatalogue/mathfonts.html}
%
% \subsubsection{\hologo{pdfLaTeX}}
% For \hologo{pdfLaTeX} there is a solution which combines the letters of the default Text font (Charter) with math symbols of different fonts.
%
% \begin{example}
% \usepackage[charter,expert]{mathdesign}
% \end{example}
%
% There are similar approaches for a few other combinations.
% Some examples can be found in the XCharter documentation \cite{xcharter}.
% \url{http://mirrors.ctan.org/fonts/xcharter/doc/xcharter-doc.pdf}
%
% \section{Customization using \KOMAScript}
% \label{sec:KOMA}
% As the class is fully \KOMAScript-compatible apart from a few forced settings that affect the layout, a look at the \KOMAScript documentation \cite{scrguide-en} is helpful for any kind of modifications.
% For most of the possible modifications \KOMAScript offers its own solutions, which often makes supplementary packages superfluous.
% Examples of typical modifications that are also permitted as part of the corporate design:
% \begin{itemize}
%   \item Change paragraphs to use a skip instead of an indent of the first line (option \option{parskip})
%   \item Element numbering with or without end dot (option \option{numbers=enddot/noenddot})
%   \item Caption positioning, alignment and spacing (The macros \cs{captionabove}, \cs{captionbelow}, \cs{captionof} and the \option{captions} option)
% \end{itemize}
%
% \section{Known issues and incompatibilities}
%
% \subsection{\texorpdfstring{\hologo{XeLaTeX}}{XeLaTeX} and PDF/A}
% If the \pkg{pdfx} package is used together with \hologo{XeLaTeX} for the creation of PDF/A the support is limited.
% There will be a corresponding warning.
% With some \hologo{XeLaTeX} versions it's possible that there even may be errors.
% \hologo{LuaLaTeX} should be preferred, but in the worst case switching to the \pkg{pdfmanagement} mechanism could also help.
%
% \subsection{DVI Output}
% Due to the default setting for creating a PDF/A file, it is not possible to use TUDa-CI in standard settings to create a DVI file.
% However, a large part of the functionality can be used when \option{pdfa} mode is deactivated.
%
% \subsection{Possible option clash for microtype}
% The \pkg{microtype} package is loaded automatically if \hologo{pdfLaTeX} is used, as the ligatures for small caps must be deactivated in the font to avoid problems (see \url{https://github.com/tudace/tuda_ latex_templates/issues/144}).
% It is possible to pass further options to \pkg{microtype} before loading the document class:
% \begin{Syntax}
% \PassOptionsToPackage{|\meta{microtype options}|}{microtype}
% \documentclass{tudapub}
% \end{Syntax}
%
%
% \chapter{Department-specific adaptations}
% \label{sec:department-config}
% Some departments have special requirements.
% TUDa-CI includes an interface to be extended in that way.
% Currently the only official extension is the one for the department of mechanical engineering.
% However, the mechanism can be expanded.
%
% \section{Department of Mechanical Engineering}
% \label{sec:mecheng}
% The corresponding mode is activated via the option \option{department=mecheng}.
% Coloring is adjusted automatically and additional layout elements like the \foreignquote{german}{Zeitstrahl} are introduced.
% The modifications exist for all document types provided by TUDa-CI.
%
% \DescribeMacro{\SetPaperID}
% In addition, some documents require the placement of document identifier on the titlepage.
% For this purpose \cs{SetPaperID} was introduced.
% \begin{Syntax}
% \SetPaperID{|\meta{Letter}|}{|\meta{ID}|}
% \end{Syntax}
% This also works without activating \option{mecheng} mode.
% However, the option adds some additional parameters for customized distances.
%
% The mode also sets the options: \option{colorback=false} and \option{ruledheaders=section}.
%
% \subsubsection{Department logo}
% \DescribeKeyOption{departmentlogofile=\meta{filename}}{tuda\_maschinenbau\_logo}*
% The department logo can be downloaded and installed the same way as the TUDa logo.
% A different file can also be selected using the option.
% If the value remains empty, no image is inserted.
%
% \subsubsection{Colors}
% \label{sec:mecheng-color}
% The department subdivides the colors described in the corporate design manual.
% Therefore, if \option{department=mecheng} has been activated, the following color names also exist:
%
% \begin{example}
% \colorlet{TUDa-Primary1}{TUDa-6b}
% \colorlet{TUDa-Primary2}{TUDa-2d}
% \colorlet{TUDa-Secondary1}{TUDa-9a}
% \colorlet{TUDa-Secondary2}{TUDa-8a}
% \colorlet{TUDa-Secondary3}{TUDa-6a}
% \colorlet{TUDa-Secondary4}{TUDa-3a}
% \colorlet{TUDa-Secondary5}{TUDa-4a}
% \colorlet{TUDa-Secondary6}{TUDa-5a}
% \colorlet{TUDa-Arrow}{TUDa-Primary2}
% \end{example}
%
% \minisec{\foreignquote{german}{Zeitstrahl} arrow}
% \DescribeMacro{\MechEngArrow}
% The design element of the timeline can be created using the macro \cs{MechEngArrow\marg{length}}.
% The color corresponds to the color \code{TUDaArrow}, which is pre-assigned with the second primary color (blue).
