% \section{Introduction}
%
% \XeTeX{} allows us to make use of pretty much all possible fonts.
% With all the possible fonts that can be used and the many features provided
% by OpenType fonts, it can be useful to compile a font book of your favorite
% fonts, so you can find the one you need more easily. This is what the 
% \textsf{fontbook} package is about.
% 
%
% \section{Usage}
%
% To use this package, simply include it:
%
% \begin{verbatim}
% \usepackage{fontbook}
% \end{verbatim}
%
% \subsection{Package Options}
%
% This package provides several options to fine-tune the way its commands react.
%
% \subsubsection{The \textsf{sizes} option}
%
%   The \textsf{sizes} option lets you define which sizes
%   are to be printed for each font.
%   By default, all sizes from \textsf{huge} to \textsf{tiny} downward
%   are used:
%   \makeatletter\textsf{\fontbook@allsizes}\makeatother.
%   This option can take a single value or a list
%   of comma-separated values:
%
% \begin{verbatim}
% \usepackage[sizes={large,huge}]{fontbook}
% \end{verbatim}
%
% \subsubsection{The \textsf{features} option}
% 
%   Similarly to the \textsf{sizes} option, the \textsf{features} option
%   lets you define which features you wish to print for each font.
%   By default, the following features are used:
%   \makeatletter\textsf{\fontbook@allfeatures}\makeatother.
%   This option can take a single value or a list
%   of comma-separated values:
%
% \begin{verbatim}
% \usepackage[features=scshape]{fontbook}
% \end{verbatim}
%
% \subsubsection{The \textsf{featuresize} option}
%
%   By default, features are typeset in size
%   \makeatletter\textsf{\fontbook@defaultfeaturesize}\makeatother.
%   This can be changed by passing the desired size name
%   as the \textsf{featuresize} option:
%
% \begin{verbatim}
% \usepackage[featuresize=huge]{fontbook}
% \end{verbatim}
%
% \subsection{Package commands}
%
% \DescribeMacro{\setsampletext}
%
%   Set the sample text used in the font demo.
%
% \DescribeMacro{\printfont}
%
%   This is the main command of this package
%   It takes 2 mandatory arguments and 1 optional argument.
%   The 2 mandatory arguments are the font name, as passed to
%   \textsf{fontspec}, and the license.
%   The optional argument is the fontspec option that allow
%   to set OpenType features for example:
%
% \begin{verbatim}
% \printfont[Ligatures=Rare]{Linux Libertine O}{Public Domain}
% \end{verbatim}
%
% \StopEventually{}
