-% \section{Introduction}
-%
-% This document describes the \pkg{xltxtra} package.
-% It implements some odds-and-ends features when using the \XeLaTeX\ format.
-%
-% \subsection{Usage}
-% Easy: |\usepackage{xltxtra}|. This package automatically loads the following packages: \pkg{fontspec}, \pkg{realscripts}, \pkg{metalogo}.
-%
-% There are some package options to disable various functionality that could clash with other things:
-% \begin{description}[font=\ttfamily]
-% \item[no-sscript] Swaps the definitions of \cmd\textsubscript\ and \cmd\textsuperscript\ with their respective starred versions, as described in \secref{sscript}.
-% \item[no-logos] Disables the redefinition of \cmd\TeX, etc. described in \secref{logos}, but \emph{does} still define the \cmd\XeTeX\ and \cmd\XeLaTeX\ logo commands.
-% \end{description}
-%
-% \section{Features}
-%
-% \subsection{\cmd\textsuperscript\ and \cmd\textsubscript}
-% \seclabel{sscript}
-%
-% This functionality is achieved through loading the \pkg{realscripts}
-% package.
-%
-% These two macros have been redefined to take advantage, if possible, of actual superior or inferior glyphs in the main document font. This is very important for high-quality typesetting — compare this first example to the third; yes, they are the same font.
-% \begin{quotation}\color{niceblue}
-%	\fontspec{Skia}
-%	  |\textsuperscript     | \textsuperscript{abcdefghijklmnopqrstuvwxyz1234567890}\par
-%	  |\textsubscript       | \textsubscript{abcdefghijklmnopqrstuvwxyz1234567890}
-% \end{quotation}
-% But will fall back on `faked' ones if they don't exist:
-% (this is {\fontspec{Didot} Didot})
-% \begin{quotation}\color{niceblue}
-%	\fontspec{Didot}
-%	  |\textsuperscript     | \textsuperscript{abcdefghijklmnopqrstuvwxyz1234567890}\par
-%	  |\textsubscript       | \textsubscript{abcdefghijklmnopqrstuvwxyz1234567890}
-% \end{quotation}
-% The original definitions are available in starred verions of the commands:
-% \begin{quotation}\color{niceblue}
-%	\fontspec{Skia}
-%	  |\textsuperscript*    | \textsuperscript*{abcdefghijklmnopqrstuvwxyz1234567890}\par
-%	  |\textsubscript*      | \textsubscript*{abcdefghijklmnopqrstuvwxyz1234567890}
-% \end{quotation}
-%
-% The \pkgopt{no-sscript} will swap the definitions of the starred and non-starred versions of the commands described above if the new definitions are undesirable.
-%
-% The macros
-% \cmd\realsubscript,
-% \cmd\realsuperscript,
-% \cmd\fakesubscript, and
-% \cmd\fakesuperscript\
-% may be used to access the `new' and `old' functionalities regardless of the \pkgopt{no-sscript}.
-%
-%
-%
-%
-% \subsection{Logos}
-% \seclabel{logos}
-%
-% This part of the package essentially exists to define the \cmd\XeTeX\ and \cmd\XeLaTeX\ logos,
-% which need to be tuned according to the font that is used. Originally I had some hard-coded
-% definitions in here, but Andrew Moschou’s |metalogo| package now provides a much more
-% flexible and useful interface to a variety of \TeX-related logos.
-%
-% Here are some examples. The default:
-% \begingroup
-% \setlogokern{Xe}{default}
-% \setlogokern{eL}{default}
-% \setlogokern{La}{default}
-% \setlogokern{aT}{default}
-% \setlogokern{Te}{default}
-% \setlogokern{eX}{default}
-% \setlogokern{eT}{default}
-% \setlogokern{X2}{default}
-% \setlogodrop{default}
-% \setLaTeXa{default}
-% \setLaTeXee{default}
-% \begin{example}
-%   \TeX\ \XeTeX\ \LaTeX\ \XeLaTeX
-% \end{example}
-% \noindent Notice that it's a bit tight when not using Computer Modern, for which the logos were designed:
-% \begin{example}
-%   \usefont{OT1}{cmr}{m}{n}
-%   \TeX\ \XeTeX\ \LaTeX\ \XeLaTeX
-% \end{example}
-% \endgroup
-%
-% These logos, ideally, should be hand-tuned for each font that they're used in. Please refer to the |metalogo| documentation for more information.
-%
-% The \pkgopt{no-logos} will not redefine \cmd\TeX\ or \cmd\LaTeX\ but will still define \cmd\XeTeX\ and \cmd\XeLaTeX.
-%
-%
-% \subsection{Vulgar fractions}
-% The \cmd\vfrac\ command for setting `vulgar' fractions based on AAT or OpenType font features. Not really recommended for many purposes, depending on your text, but it's a good example of how to program such things using \pkg{fontspec}.
-% \begin{example}
-%   \fontspec{LibreCaslonText-Regular.otf}
-%   \vfrac{123}{456}
-% \end{example}
-% \noindent (This can also be achieved in regular \LaTeX\ with either the \pkg{nicefrac} or \pkg{xfrac} package.)
-%
-% Only use it when you know it will work; no warnings are given if the font doesn't support the necessary features.
-%
-% \subsection{Named glyphs}
-% Along the way somewhere, \XeTeX\ added support for selecting glyphs from a TrueType-based OpenType font based on their internal glyph name. Jonathan Kew posted the following definition as a nice interface to it.
-% \begin{example}
-%   \fontspec{charis}
-%   \namedglyph{yen}
-%   \namedglyph{smile}
-% \end{example}
-%
-% \subsection{The \cmd\showhyphens\ command}
-% The default definition doesn't work in \XeTeX.
-% A new version, written by Enrico Gregorio, is included in this package that \emph{does} work; note that the syntax now matches plain \TeX's original rather than the comma-list approach taken by an earlier version of this package.

-% \section{Logos}
-% \DescribeMacro{\XeTeX}
-% \DescribeMacro{\XeLaTeX}
-% The \TeX-related logos people insist upon using need to be tuned
-% on a per-font  basis. This package calls upon Andrew Moschou's package
-% |metalogo| for this purpose. To tune the logos to each font,
-% use the commands \cmd\setlogokern, \cmd\setlogodrop, etc.\ Refer to
-% |mathspec|’s documentation for further details.
-%
-% \begin{example}
-%   \setlogokern{Xe}{-0.061em}
