+\section{Usage}
+\label{sec:usage}
+\emph{Old Standard T} works with \TeX\ engines that directly support
+OpenType features such as \XeTeX\ and \LuaTeX.
+
+It is loaded with \pkg{fontspec} like so:---
+\begin{code}
+ \usepackage{fontspec}
+ \setmainfont{Old Standard T}
+\end{code}
+
+\paragraph{Small capitals}
+Small capitals have been added in \emph{Old Standard T} for the
+following languages or transcription schemes: French, German, Italian,
+Spanish, unaccented Greek, basic Russian and Arabic \enquote*{DMG}.
+
+The following two examples demonstrate the use of small capitals:---

+ MR.\ SHERLOCK HOLMES
+ \end{center}
+
+ \lettrine[loversize=0.2]{M}{r.\ Sherlock Holmes}, who was usually
+ very late in the mornings, save upon those not infrequent occasions
+ when he stayed up all night, was seated at the breakfast table. I
+ stood upon the hearth-rug and picked up the stick which our visitor
+ had left behind him the night before. It was a fine, thick piece of
+ wood, bulbous-headed, of the sort which is known as a
+ \enquote{Penang lawyer.} Just under the head was a broad silver
+ band, nearly an inch across. \enquote{To James Mortimer, M.R.C.S.,
+ from his friends of the C.C.H.,} was engraved upon it, with the
+ date \enquote{1884.} It was just such a stick as the old-fashioned
+ family practitioner used to carry—dignified, solid, and reassuring.

+\paragraph{The letter \enquote*{ǧ}} It is used notably to print
+romanized Arabic. \emph{Old Standard T} now features this letter in
+all of the three styles (Regular, Italic and Bold):---
+\begin{tcblisting}{minted language=latex, minted
+ options={fontsize=\smaller, linenos, numbersep=0mm,
+ highlightlines={3,6,9}}}
+ \begin{arab}[trans]

+\end{tcblisting}
+
+\paragraph{\texttt{+ss06} OpenType feature} It is commonly believed
+that all Greek vowels with acute accent taken from the Greek Extended
+Unicode block \verb|1F00–1FFF| along with standalone acute accents
+were duplicated from the Greek and Coptic Unicode block. Affected
+characters from the Greek Extended Unicode block (\verb|0370–03FF|)
+follow: \textgrc{ά, έ, ή, ί, ό, ύ, ώ, Ά, Έ, Ή, Ί, Ό, Ύ, Ώ, ΐ, ΰ, ´,
+ ΅}. The counterparts of these letters in the Greek and Coptic
+Unicode block are vowels with \emph{tonoi}.
+
+However, strictly speaking, \emph{tonos} is not to be mistaken for
+\enquote*{acute}: that is for sure, as \emph{tonos} was introduced as
+a result of a reform to denote a tone, namely a stress on some vowels,
+and not a pitch, namely a rising and falling voice on accented vowels.
+Confusion began when the Greek government decreed that \emph{tonos}
+shall be the acute. From what the writer could see, many Greek fonts
+originally reflected the distinction between \emph{tonos} and acute.
+But nowadays, they simply mix them up. As a result of this confusion,
+in \emph{Old Standard}, vowels with acute were simply missing from the
+Greek Extended Block. All of them, including the standalone accents,
+have been restored in \emph{Old Standard T}. Furthermore, the rule
+that instructed to absorb vowels with acute into vowels with
+\emph{tonos} has been removed.
+
+Since assigning vowels with \emph{tonos} and vowels with acute to the
+same code points is clearly unacceptable even if the glyphs are
+identical, it is now possible in \emph{Old Standard T} to input all
+accented vowels from the Greek Extended Unicode block exclusively and
+have the substitution rules applied at the same time, as shown by the
+example that follows:---
+\begin{tcblisting}{minted language=latex, minted
+ options={fontsize=\smaller, linenos, numbersep=0mm,
+ highlightlines={9-10}}}
+ \begin{grc}
+ \begin{center}
+ \textlarger{ΙΠΠΟΚΡΑΤΟΥΣ ΕΠΙΔΗΜΙΩΝ ΤΟ ΔΕΥΤΕΡΟΝ}.
+
+ ΤΜΗΜΑ ΠΡΩΤΟΝ.
+ \end{center}
+
+ \textbf{1.} Ἄνθρακες θερινοὶ ἐν Κραννῶνι· ὗεν ἐν καύμασιν ὕδατι
+ λάβρῳ δι’ ὅλου καὶ ἐγίνετο μᾶλλον νότῳ, [καὶ] ὑπογίνονται μὲν ἐν
+ τῷ δέρματι ἰχῶρες· ἐγκαταλαμβανόμενοι δέ, θερμαίνονται, καὶ
+ κνησμὸν ἐμποιέουσιν· εἶτα φλυκταινίδες ὥσπερ πυρίκαυστοι
+ ἐπανίσταντο καὶ ὑπὸ τὸ δέρμα καίεσθαι ἐδόκεον.
+ \end{grc}
+\end{tcblisting}
+
+\subsection{Bold Italic shape}
+\label{sec:bold-italic-shape}
+As \emph{Old Standard}, \emph{Old Standard T} does not feature a bold
+italic shape. However, both \XeTeX\ and \LuaTeX\ engines can emulate
+this shape as shown in the following two examples:
+
+\begin{tcblisting}{minted options={linenos, numbersep=0mm,
+ fontsize=\smaller}, listing only, title=\XeLaTeX}
+ \usepackage{fontspec}
+ \setmainfont{Old Standard T}[
+ BoldItalicFont={Old Standard T Italic},
+ BoldItalicFeatures={FakeBold=1.5}]
+\end{tcblisting}
+
+\begin{tcblisting}{minted options={linenos, numbersep=0mm,
+ fontsize=\smaller}, listing only, title=\LuaLaTeX}
+ \usepackage{fontspec}
+ \setmainfont{Old Standard T}[
+ BoldItalicFont={Old Standard T Italic},
+ BoldItalicFeatures={RawFeature={+embolden=2}}]
+\end{tcblisting}
+
+\subsection{Using \emph{Old Standard T} in multilingual
+ documents}
+\label{sec:using-old-standard}
+\pkg{babel} provides a high level interface on top of \pkg{fontspec}
+to select fonts depending on the languages to be used.\icite[For more
+information, the reader should refer to][10,24]{babel} As an example,
+here is how \emph{Old Standard T} has been loaded in the preamble of
+this document to be compiled with \LuaLaTeX:---
+\begin{code}
+ \usepackage[no-math]{fontspec}
+ \usepackage{fontspec}
+ \usepackage[greek.ancient,english]{babel}
+ \babeltags{grc = greek}
+
+ \babelfont{rm}[BoldItalicFont={Old Standard T Italic},
+ BoldItalicFeatures={RawFeature={+embolden=2}}]{Old Standard T}
+
+ \babelfont[greek]{rm}[RawFeature={+ss05;+ss06},
+ BoldItalicFont={Old Standard T Italic},
+ BoldItalicFeatures={RawFeature={+embolden=2}}]{Old Standard T}
+\end{code}
