+% Collection of tools, which are helpful for the creation of a \LaTeX{}
+% template if conditional paths for code execution are required.
+% \end{abstract}
+%
+% \section{Usage}
+%
+% \subsection{Commands}
+% The following commands check if a command sequence is defined or not.
+%
+% \DescribeMacro{\IfDefined} \marg{command}\marg{code defined} \AfterLastParam
+% Executes the code if the command is defined.
+%
+%
+% \DescribeMacro{\IfUndefined} \marg{command}\marg{code undefined}
+% \AfterLastParam
+% Executes the code if the command is not defined.
+%
+% \DescribeMacro{\IfElseDefined} \marg{command}\marg{defined}\marg{undefined}
+% \AfterLastParam
+% Executes either the code in the \emph{defined} bracket if the command is
+% defined or in the \emph{undefined} bracket if the code is undefined.
+%
+% \DescribeMacro{\IfElseUndefined} \marg{command}\marg{undefined}\marg{defined}
+% \AfterLastParam
+% As \cs{IfElseDefined}, but with switched brackets for defined and undefined.
+%
+%
+% \subsubsection{Example}
+% The \cs{usepackage} code is only executed if the required \cs{upmu} command
+% is defined.
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}[style=lstDemoStyleLaTeXCode]
+% Requires: Command \upmu
+\IfDefined{upmu}{\usepackage[upmu]{gensymb}}
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+%
+%
+% \DescribeMacro{\IfMultDefined}
+% \marg{list of commands}\marg{defined}\marg{undefined} \AfterLastParam
+% Checks a comma separated list of commands before it executes the defined
+% code path if all commands were defined or the undefined code path else.
+%
+% \subsubsection{Example}
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}[style=lstDemoStyleLaTeXCode]
+% Requires: Command longtable and rowcolors
+\IfMultDefined{longtable,rowcolors}
+ {... longtable with rowcolors ...}
+ {Error: Neither longtable nor rowcolors are defined}
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+%
+% \subsection{Draft mode}
+%
+% The following commands check if draft mode is active or not.
+%
+% \DescribeMacro{\IfDraft}\marg{draft mode active}
+% \AfterLastParam
+%
+% \DescribeMacro{\IfNotDraft}\marg{draft mode disabled}
+% \AfterLastParam
+%
+% \DescribeMacro{\IfNotDraftElse}\marg{draft mode disabled}\marg{draft mode active}
+% \AfterLastParam
+%
+% \subsubsection{Example}
+% The \package{bookmark} is not loaded in draft mode:
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}[style=lstDemoStyleLaTeXCode]
+\IfNotDraft{\usepackage[]{bookmark}}
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+%
+%
+% \subsection{Packages}
+%
+% These commands check if a package was loaded or not.
+% This can be achieved in different ways with commands from other packages.
+% The key point of these commands here is that they work not only in
+% the preamble and include no @-char.
+%
+% \DescribeMacro{\IfPackageLoaded}\marg{package}\marg{is loaded}
+% \AfterLastParam
+%
+% \DescribeMacro{\IfPackageNotLoaded}\marg{package}\marg{is not loaded}
+% \AfterLastParam
+%
+% \DescribeMacro{\IfPackagesLoaded}\marg{list of packages}\marg{all are loaded}
+% \AfterLastParam
+%
+% \DescribeMacro{\IfPackagesNotLoaded}\marg{list of packages}\marg{none is loaded}
+% \AfterLastParam
+%
+% \subsubsection{Example}
+%
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}[style=lstDemoStyleLaTeXCode]
+% Load epstopdf only if graphicx was loaded
+\IfPackageLoaded{graphicx}{%
+ \usepackage{epstopdf}
+}
+% Do not load subcaption if subfig was loaded (incompatible)
+\IfPackageNotLoaded{subfig}{
+ \usepackage{subcaption}[2011/08/17]
+}
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+%
+%
+% \subsection{Package Loading order}
+% In \latex{} documents it is quite often essential
+% to load packages in the right order to ensure that everything works.
+% However this makes it impossible to group similar packages together.
+%
+% The following commands allow to execute code after or before a
+% specified package and thus also allows to load packages in a specified order
+% using \cs{usepackage} commands.
+%
+% If the reference package was not loaded in the preamble
+% the code will nevertheless be executed before \texttt{\cs{begin}\{document\}}
+%
+%
+% \DescribeMacro{\ExecuteAfterPackage}
+% \marg{after this package}\marg{execute this code}\AfterLastParam
+%
+% \DescribeMacro{\ExecuteBeforePackage}
+% \marg{before this package}\marg{execute this code}\AfterLastParam
+%
+% \subsubsection{Example}
+% \package{cleveref} package must be loaded after package \package{hyperref}.
+%
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}[style=lstDemoStyleLaTeXCode]
+% loading: must be loaded after hyperref and after varioref
+\ExecuteAfterPackage{hyperref}{
+% caption and cleveref incompatible in Versions before 2011/12/24
+ \usepackage{cleveref}[2011/12/24]
+}
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+%
+% \subsection{Tikz Library}
+% Checks if a tikz library was loaded.
+%
+% \DescribeMacro{\IfTikzLibraryLoaded}\marg{library}\marg{if loaded}
+%
+%
+% \subsubsection{Example}
+% Executes the code only of the tikz library was loaded.
+%
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}[style=lstDemoStyleLaTeXCode]
+\IfTikzLibraryLoaded{lindenmayersystems}{%
+% code origin: pgf/tikz manual
+\begin{tikzpicture}
+\pgfdeclarelindenmayersystem{Koch curve}{
+ \rule{F -> F-F++F-F}
+}
+\shadedraw [top color=white, bottom color=blue!50, draw=blue!50!black]
+ [l-system={Koch curve, step=2pt, angle=60, axiom=F++F++F, order=3}]
+ lindenmayer system -- cycle;
+\end{tikzpicture}
+}%
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+%
+% \subsection{Column types}
+%
+% \LaTeX{} provides no tool to check for the existence of a column type.
+% This is provided by the following commands:
+%
+% \DescribeMacro{\IfColumntypeDefined}\marg{columntype character}\marg{is
+% defined}\marg{is undefined} \AfterLastParam
+%
+% ^^A which is also available as a command checking a comma separated list for
+% ^^A column type characters
+%
+% \DescribeMacro{\IfColumntypesDefined}
+% \marg{columntype character list}\marg{is defined}\marg{is undefined}
+% \AfterLastParam
+%
+% \subsubsection{Example}
+% Executes the code only of the X column type is defined and the tabularx package was
+% loaded by checking that \cs{tabularx} is defined.
+%
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}[style=lstDemoStyleLaTeXCode]
+\IfColumntypeDefined{X}{%
+\IfDefined{tabularx}{%
+%
+\begin{tabularx}{0.9\textwidth}{llXX}
+\hline
+l & l & X & X \\\hline
+%
+left column & left column &
+text which is considerably longer than the width of the column &
+text which is considerably longer than the width of the column \\
+\hline
+\end{tabularx}
+%
+}}%
+\end{lstlisting}
+% \iffalse
+%</example>
+% \fi
+
+% \subsection{Color definitions}
+%
+% Color definitions are saved in \latex{} as names. The following commands
+% provide a convenient way to check the existence of these color definitions.
+%
+% \DescribeMacro{\IfColorDefined}
+% \marg{color name}\marg{is defined}\marg{is undefined} \AfterLastParam
+%
+%
+% \DescribeMacro{\IfColorsDefined}
+% \marg{list of color name}\marg{is defined}\marg{is undefined} \AfterLastParam
+%
+% \subsection{Math font version}
+% \DescribeMacro{\IfMathVersionDefined}
+% \marg{font version}\marg{is defined}\marg{is undefined} \AfterLastParam
+%
+%
+% \subsection{Glossaries styles}
+% \DescribeMacro{\IfGlossariesStyleDefined}
+% \marg{style name}\marg{is defined} \AfterLastParam
+%
+%
+% \subsection{Template Definitions}
+% The following commands in principle define only macros, but in contrast to
+% normal methods these are saved using two keys named \emph{group}
+% and \emph{property}. With a matching command for the execution this
+% allows to generate macros in an object like naming structure, which
+% can be used to toggle settings.
+%
+% \DescribeMacro{\SetTemplateDefinition} \marg{Group}\marg{Property}\marg{Code}
+% \AfterLastParam
+% Defines a collection of commands (a macro) with a \emph{group} and
+% \emph{property}.
+%
+% \DescribeMacro{\UseDefinition} \marg{Group}\marg{Property} \AfterLastParam
+% Execute macro save with the \emph{group} and \emph{property}.
+%
+% \subsubsection{Example}
+% The following code allows to switch the colors anywhere in the document:
+%
+% \iffalse
+%<*example>
+% \fi
+\begin{lstlisting}[style=lstDemoStyleLaTeXCode]
+\SetTemplateDefinition{Target}{Web}{%
+ \definecolor{pdfurlcolor}{rgb}{0,0,0.6}
+}%
+\SetTemplateDefinition{Target}{Print}{%
+ \definecolor{pdfurlcolor}{rgb}{0,0,0}
+}%
+% Apply colors for web
+\UseDefinition{Target}{Web}
