+% \section{Introduction}
+%
+% Using OpenType fonts within \XeLaTeX\ or \LuaTeX\ comes with a lot of
+% benefits, but also the problem, that desired fonts may not be installed on
+% the system, the user choses for the compilation. In case they are, there can
+% still be different revisions of a font with variant names, such as
+% \textit{Frutiger LT Std}, \textit{Frutiger Neue LT Pro} and \textit{Frutiger
+% Next Pro}.
+%
+% Inspired by a question on \href{http://tex.stackexchange.com/q/53443/}
+% {Stack Exchange} and a discussion on the
+% \href{http://tug.org/pipermail/xetex/2010-August/017833.html}{\XeTeX\
+% Mailinglist}, this package addresses the problem with a set of easy to use
+% macros: a macro to select the first font \XeLaTeX\ or \LuaTeX\ can find in a
+% comma separated list and, additionally, a number of macro tests.
+%
+% \section{Select a Font from a List of Fonts}
+%
+% \DescribeMacro{\settofirstfound} This command defines a new macro with the
+% first font found in the comma separated list. The list is provided as second
+% argument. The macro can then be used to set the main font, set the sans
+% font, define a new font family and so on. The following code shows how to
+% set the main font as the Frutiger Font with the black font weight as bold
+% font.
+% \begin{lstlisting}
+% \documentclass{article}
+% \usepackage{fontspec}
+% \usepackage{iffont}
+% \settofirstfound{\mainfont}{Frutiger Next Pro,
+%                             Frutiger Neue LT Pro,
+%                             Frutiger LT Std}
+% \settofirstfound{\boldfont}{Frutiger Next Pro Black,
+%                             Frutiger Neue LT Pro Black,
+%                             Frutiger LT Std 75 Black}
+% \setmainfont[BoldFont=\boldfont]{\mainfont}
+% \begin{document}
+% \begin{itemize}
+%   \item \mainfont
+%   \item \textbf{\boldfont}
+% \end{itemize}
+% \end{document}
+% \end{lstlisting}
+% Defining a new font family works just the same.
+% \begin{lstlisting}
+% \documentclass{article}
+% \usepackage{fontspec}
+% \usepackage{iffont}
+% \settofirstfound{\lightfont}{Frutiger Next Pro Light,
+%                              Frutiger Neue LT Pro Light,
+%                              Frutiger LT Std 45 Light}
+% \newfontfamily\FrutigerLight{\lightfont}
+% \begin{document}
+% \begin{itemize}
+%   \item {\FrutigerLight \lightfont}
+% \end{itemize}
+% \end{document}
+% \end{lstlisting}
+% \StopEventually{}
+%
+% \section{Macro Tests}
+% In most cases the \lstinline|\settofirstfound| command is sufficient, but
+% for the more demanding user there is also a set of macro tests. They are
+% useful, if one wants to set specific font features only if the first choice
+% font cannot be found. The original \textit{Frutiger LT Std} font for example
+% does not support small caps. So in the following example the
+% \lstinline|\textsc|command is redefined as uppercase with increased letter
+% spacing, but only if the \textit{Frutiger Next Pro} font cannot be found.
+% \begin{lstlisting}
+% \documentclass{article}
+% \usepackage{fontspec}
+% \usepackage{iffont}
+% \settofirstfound{\mainfont}{Frutiger Next Pro,
+%                             Frutiger LT Std}
+% \setmainfont{\mainfont}
+% \ifxfontexists{Frutiger Next Pro}{%
+%   \def\textsc#1{\addfontfeature{LetterSpace=5.0}%
+%                 \MakeUppercase{#1}}
+% }{}
+% \begin{document}
+% \begin{itemize}
+%   \item \mainfont
+%   \item \textsc{\mainfont}
+% \end{itemize}
+% \end{document}
