+This package, derived from Daniel Benjamin Miller's XETBook, which is in turn derived from ETBook, a font commissioned by Edward Tufte for use in his own books,
+provides a version of Bembo in otf and pfb formats plus LaTeX font support files. As ETBook is licensed under the MIT license, so are the font files in this package. See the LICENSE file in the doc folder for details of the MIT license. All other support files are subject to the LaTeX Project Public License. See 
+http://www.ctan.org/license/lppl1.3
+for the details of that license. Note that Bembo is a name trademarked by Monotype, hence the strange name for this package, drawn from the Berry id for the Bembo font family.
+
+Current version: 1.057 2023-12-10
+
+Changes in version 1.057
+1. Modified spacing and kerning of a number of glyphs in order to prevent collisions with parentheses and brackets.
+2. Modified the placements of some accents on lowercase letters where the previous positions seemed too close.
+3. Added a question.alt glyph with larger left sidebearing, available only using xelatex and lualated though ss09.
+
+Changes in version 1.056
+1. Added definitions of \nustyle and \destyle to ETbb.sty.
+2. Corrected behavior of option sharpS in legacy LaTeX..
+3. Corrected misbehavior of \Qswash and \Qnoswash.
+4. Extended small cap coverage in all styles so that all 
+T1 encoded characters are available.
+
+Changes in version 1.055
+1. Further revision of the kerning tables in regular style, mostly for uppercase and small cap glyphs.
+2. Added aeacute.sc glyph.
+3. Corrected for some missing c2sc and smscp lookup table entries.
+4. Added a fraction.alt glyph to allow a decent fraction
+construction in unicode latex. (Regular style only, so far.)
+
+Changes in version 1.054
+Version 1.053 seems to have corrupted the kerning tables. 
+This version restores the kerning tables to their values in version
+1.051.
+
+Changes in version 1.053
+Modified a number of settings in the otf files in order that the otf fonts work as expected in Windows 10. (Thanks Espen Solheim.)
+
+Changes in version 1.051
+Modified the \textcircled macro so as to scale as expected.
+
+Changes in version 1.05
+1. Added swashQ glyph to all faces, along with changes to latex support to enable it. See the documentation.
+2. Full support now enabled for all features in LY1 and OT1 as well as T1.
+
+Changes in version 1.04
+1. Added glyph numero (U+2116) in all styles.
+2. Updated code for \textfrac. See documentation for details.
+
+Changes in version 1.03
+Removed all hinting in the font files. This will not affect Mac or PC users, but should be helpful to some Linux users whose font renderers can behave badly at times with Postscript hinting.
+
+Changes in version 1.02
+1. Added denominator figures to all styles.
+2. Changed the \fraction macro to use denominators and allow finer tuning of spacing between figures and the fractionsolidus.
+3. Filled out the glyph slots for symbols in the TS1 encoding so the sub-encoding is close to full.
+4. Added newstyle dollar and cent glyphs and added option osdollar to select the oldstyle dollar and cent as the default.
+
+Changes in version 1.01
+1. Reverted the changes in 1.001 so that sty file is ETbb.sty and fontspec file is ETbb.fontspec. The prior change was muddled. 
+2. Added option osf as a synonym for oldstyle. (Thanks Axel Kielhorn.)
+2. Documentation changes to reflect the changes. 
+3. Modified some glitches in some BoldItalic figure outlines. (Thanks Daniel Benjamin Miller.)
+
+Changes in version 1.001
+Changed the package name from ETbb to etbb, though the font names and the map file name continue to use ETbb.

+\maketitle
+\section*{Background}
+
+
+The fonts in this package were derived ultimately from the collection of fonts commissioned by Edward Tufte for his own books, and released in 2015 as {\tt ET-Bembo} under the MIT license. (The sources for that collection were fonts using the family name ET-book.) That collection was enhanced in 2019 under the name {\tt XETBook} by  Daniel Benjamin Miller, and it is his package which was the starting point for {\tt ETbb}, where the {\tt bb} denotes the Berry abbreviation for Bembo. The final section of this document makes a detailed comparison with the earlier {\tt fbb} package, which is also  Bembo-like, derived from {\tt Cardo.} The most significant differences are that {\tt ETbb} has a regular upright that is about 20\% darker than the corresponding {\tt fbb}, and its ascender height is noticeably less. These differences make {\tt ETbb} have a less spindly appearance that is closer in spirit to the print produced by traditional metal versions of Bembo.
+
+
+\section*{Package properties}
+
+The package makes a number of changes to the {\tt XETBook} fonts:
+\begin{itemize}
+\item  The  released version of ET-Bembo lacks kerning tables---a serious omission---rectified in {\tt ETbb}.  
+\item
+The scale has been increased by 3.36\% so that the x-height of the upright regular face is 431, very close to Computer Modern and Libertine.
+\item The lining figures in some faces were reduced so as to be a bit less than the cap-heights.
+\item The lining figures in {\tt XETBook} were proportional rather than tabular. I've added new tabular lining and old-style figures.
+\item Added superior letters and figures to all faces. E.g., \verb|\textsu{ABCabc123}| renders as \textsu{ABCabc123}.
+\item Added inferior figures to all faces with baseline at -112{\tt em}.
+\item Added denominator figures to all faces with baseline at 0{\tt em}.
+\item The originals comprised glyphs in the Adobe Standard Encoding, forming a rather sparse subset of the T1 encoding. I've added accented and composite glyphs that provide complete coverage of the T1 encoding as well as many glyphs required in the orthography of a number Eastern European countries.
+\item Prior to version 1.02, coverage of TS$1$ encoding was meager. The coverage is now close to full. (See the table at the end of this document.)
+\item Small caps have been added to all faces.
+\item There is a new glyph for the German capital sharp S ({\altr\char223}, \textit{gro\ss es  eszett}, {\tt U+1E9E}), approved in 2017 for optional use in German orthography. Small cap versions are also provided.
+\item The glyph capital P has been changed from its default closed shape, as used in almost all modern digital renderings of Bembo, to the more historically accurate open shape. See, for example, the reproduction of Pietro Bembo's \textit{De Aetna} at \\
+\url{https://ia601405.us.archive.org/34/items/ita-bnc-ald-00000673-001/ita-bnc-ald-00000673-001.pdf}.\\ 
+(A higher resolution rendering of  a two-page sample is available from \url{https://upload.wikimedia.org/wikipedia/commons/8/89/De_Aetna_1495.jpg.})
+\end{itemize}
+
+\section*{Package options and macros}
+
+
+This package has most of the same features and options as the {\tt fbb} package and even includes the {\tt altP} option, though that has no effect because the  alternate P shapes in {\tt fbb} are the default in {\tt ETbb}. 
+
+In the original {\tt XETBook}, the dollar and cent currency symbols were oldstyle. I've added the new style symbols and made them the default, but option {\tt osdollar} to {\tt ETbb} changes back to the oldstyle symbols.
+
+
+\textbf{New in version $1.05$:} A swash version of Q has been added to all faces. You may enable it globally using option {\tt swashQ} to {\tt ETbb}, or specify it locally with the macro \verb|\Qswash|, which renders as \Qswash. This document did not specify option {\tt swashQ}. If you had enabled it globally, you have access to the ordinary Q with the macro \verb|\Qnoswash|. You may find it simpler to use the macro \verb|\altQ| which renders Q as ordinary Q if you had specified option {\tt swashQ} and as \altQ\ if not.
+
+Text figures may be selected from four types:
+\begin{itemize}
+\item
+Proportional lining (LF), selected by options {\tt lining, proportional [or p]}; ({\tt lining}, or {\tt lf}, is the default figure style;)
+\item
+Tabular lining (TLF), selected by options {\tt lining [or lf], tabular [or t]}; ({\tt tabular} is the default figure alignment;)
+\item
+Proportional oldstyle (OsF), selected by option {\tt oldstyle [or osf], proportional [or p]};
+\item
+Tabular oldstyle (TOsF), selected by options {\tt oldstyle [or osf], tabular [or t]}.
+\end{itemize}
+The package also defines macros that allow you use alternate figure styles locally:
+
+\begin{center}
+  \begin{tabular}{@{} lll @{}}
+    \toprule
+    Macro & result & comment \\ 
+    \midrule
+\verb|\textlf{0123456789}| &\textlf{0123456789} & print 0123456789 in proportional lining figures\\
+\verb|\texttlf{0123456789}|&\texttlf{0123456789}&  print 0123456789 in tabular lining figures\\
+\verb|\textosf{0123456789}| &\textosf{0123456789}& print 0123456789 in proportional oldstyle figures\\
+\verb|\texttosf{0123456789}| &\texttosf{0123456789}& print 0123456789 in tabular oldstyle figures\\
+\verb|\textsu{0123456789}| &\textsu{0123456789}& print 0123456789 in superior figures\\
+\verb|\textinf{0123456789}| &\textinf{0123456789}& print 0123456789 in inferior figures\\
+\verb|\textde{0123456789}| &\textde{0123456789}& print 0123456789 in denominator figures\\
+    \bottomrule
+  \end{tabular}
+\end{center}
+The macro \verb|\textlf{123}| is identical in effect to \verb|{\lfstyle 123}|, and similarly for the other lining and oldstyle macros, while \verb|\textsu{123}| has the same effect as \verb|{\sufigures 123}|
+and \verb|\textinf{123}| has the same effect as \verb|{\infigures 123}|.
+If you prefer typing longer names, you may use \verb|\textinferior| as a synonym for \verb|\textinf|, and similarly for \verb|\textsu|. Likewise, 
+\verb|\textde{123}| has the same effect as \verb|{\defigures 123}| or \verb|{\denomfigures 123}|, and you may use \verb|\textdenom| as a synonym for \verb|\textde|. Note the difference in baseline between \verb|\textinf| and \verb|\textde|: \textinf{123} versus \textde{123}.
+
+The \verb|\textfrac| macro constructs fractions using \verb|\textsu| and \verb|\textde| with baseline aligned with the text baseline. The behavior is somewhat configurable, there being two parameters available to control the kerns before and after the fraction solidus. The two parameters are passed as options to {\tt ETbb}, named
+\begin{verbatim}
+foresolidus % default value -.05em
+aftsolidus  % default value -.05em
+\end{verbatim}
+%raisefrac   % default value 0em
+(The values should always be {\tt em} or {\tt ex} units in order to behave correctly with respect to scaling.)
+%If you were to change the default behavior with the option
+%\begin{verbatim}
+%raisefrac=-112em
+%\end{verbatim}
+%you would get a fraction with the denominator's baseline  at the baseline of the \verb|\textin| figures, namely {\tt -.112em}. 
+%%Those who wish the fractional part to be vertically centered with respect to lining figures should specify
+%%\begin{verbatim}
+%%raisefrac=-.056em
+%%\end{verbatim}
+%All the above have to do with globally defined settings for \verb|\textfrac|, but that macro allows one optional argument that can override the effect of {\tt raisefrac}, with, e.g., \verb|\textfrac[.1em][6}{11}| raising the fraction 6/11 by {\tt .1em} instead of the default specified in the original options.
+
+\textsc{Example:}\\
+$\bullet$ \verb|\textfrac[2]{17}{32}| renders as \textfrac[2]{17}{32} with default settings. (The optional argument 2 will always print in lining figures, no matter the choice of the text figure style.)\\
+
+If you load the {\tt ETbb} package by means of option {\tt etbb} to the {\tt newtx} package, version 1.71 or higher, there is a stacked fraction construction available using the macro \verb|\textsfrac| which behaves like \verb|\textfrac| except with the fractional part stacked vertically rather than diagonally. See the {\tt newtx} documentation for details and examples.
+
+%$\bullet$ \verb|2\textfrac[.053em]{17}{32}| produces a fraction centered on the mid-height of lining figures: 2\textfrac[.053em]{17}{32}.\\
+%$\bullet$ \verb|2\textfrac[0em]{17}{32}| produces a fraction with numerator and denominator at the normal heights of superior and inferior figures: 2\textfrac[0em]{17}{32}.\\
+
+%The \verb|\textfrac| macro uses spacing control for each individual digit, one for the numerator and one for the denominator. It is optimized for regular weight, upright shape, but works satisfactorily in bold weight, upright shape. Italic shapes are not handled with any precision. Currently, the spacing settings are specified by two macros in {\tt ETbb.sty}: \verb|\tx@addNkern| and \verb|\tx@addDkern| for numerator and denominator respectively. These may be redefined in your preamble after loading the {\tt ETbb} package with a block like
+%\begin{verbatim}
+%\makeatletter
+%\renewcommand*{\tx@addNkern}[1]{%
+%.
+%.
+%.
+%}
+%\renewcommand*{\tx@addDkern}[1]{%
+%.
+%.
+%.
+%}
+%\end{verbatim}
+%following the pattern of the definitions in {|tt ETbb.sty}. You should be careful to follow those patterns precisely, as it is very easy to introduce inadvertent space characters in the output.
+
+
+Option {\tt sups} changes the form of footnote markers to use {\tt ETbb}'s superior figures, unless you have redefined the meaning of \verb|\thefootnote| prior to loading {\tt ETbb}. For more control over size, spacing and position of footnote markers, use the \textsf{superiors} package: E.g.,
+\begin{verbatim}
+\usepackage[supstfm=ETbb-Regular-sup-t1]{superiors}
+\end{verbatim}
+
+Option {\tt sharpS} replaces {\tt SS} in the {\tt T1} encoding by the new {\tt U+1E9E} glyph and replaces the small cap \textsc{ss} by the small cap version of\hspace{.5em}{\tt U+1E9E}. Only figure-styles {\tt TLF}, {\tt LF}, {\tt OsF} and {\tt TOsF} are handled, and only in the {\tt T1} encoding.
+%\SS \ss \textsc{\ss}. {\usefont{T1}{ETbb-TLF}{m}{n}\SS\ss}
+
+Option {\tt scosf} forces the use of {\tt OsF} figures in a small caps block, no matter what the default figure settings.
+
+There is a {\tt scaled [or scale]} option (\emph{e.g.}, {\tt scaled=.97}) that allow you to adjust the text size against, say, a math package. 
+
+
+\section*{A suggested math companion}
+
+This text package works well with {\tt newtxmath} with the {\tt libertine} option, because the latter has italics of the same italic angle as {\tt ETbb} and of very similar xheight and weight. If you have the MinionPro fonts (version 2.0 or higher) and have set them up with \textsf{FontPro} and the {\tt minion2newtx} \textsc{ctan} package, then the {\tt minion} option to {\tt newtxmath} provides a very good math companion with better Greek letters than {\tt libertine}. The suggested invocation for {\tt libertine} math is:
+\begin{verbatim}
+% load babel package and options here
+\usepackage[p,osf]{ETbb} % osf in text, tabular lining figures in math
+\usepackage[scaled=.95,type1]{cabin} % sans serif in style of Gill Sans
+\usepackage[varqu,varl]{zi4}% inconsolata typewriter
+\usepackage[T1]{fontenc} % LY1 also works
+\usepackage[libertine,vvarbb]{newtxmath}
+%\usepackage[cal=boondoxo,bb=boondox,frak=boondox]{mathalfa}
+\end{verbatim}
+Here is a short sample based on this preamble:\\[4pt]
+\def\Pr{\ensuremath{\mathbb{P}}}
+\def\rmd{\mathrm{d}}
+The typeset math below follows the ISO recommendations that only variables
+be set in italic. Note the use of upright shapes for $\rmd$, $\mathrm{e}$
+and $\uppi$. (The first two are entered as \verb|\mathrm{d}| and
+\verb|\mathrm{e}|, and in fonts derived from {\tt newtxmath} or {\tt mtpro2},
+ the latter is entered as \verb|\uppi|.)
+
+\textbf{Simplest form of the \textit{Central Limit Theorem}:} \textit{Let
+$X_1$, $X_2,\cdots$ be a sequence of iid random variables with mean $0$ 
+and variance $1$ on a probability space $(\Omega,\mathcal{F},\Pr)$. Then}
+\[\Pr\left(\frac{X_1+\cdots+X_n}{\sqrt{n}}\le y\right)\to\mathfrak{N}(y)\coloneq
+\int_{-\infty}^y \frac{\mathrm{e}^{-t^2/2}}{\sqrt{2\uppi}}\,
+\mathrm{d}t\quad\mbox{as $n\to\infty$,}\]
+\textit{or, equivalently, letting} $S_n\coloneq\sum_1^n X_k$,
+\[\mathbb{E} f(S_n/\sqrt{n})\to \int_{-\infty}^\infty f(t)
+\frac{\mathrm{e}^{-t^2/2}}{\sqrt{2\uppi}}\,\mathrm{d}t
+\quad\mbox{as $n\to\infty$, for every $f\in\mathrm{b}
+\mathcal{C}(\mathbb{R})$.}\]
+
+%\section{Text effects under \texttt{fontaxes}}
+%This package loads the {\tt fontaxes} package in order to access italic small caps. You should pay attention to the fact that {\tt fontaxes} modifies the behavior of some basic \LaTeX\ text macros such as \verb|\textsc| and \verb|\textup|. Under normal \LaTeX, some text effects are combined, so that, for example, \verb|\textbf{\textit{a}}| produces bold italic {\tt a}, while other effects are not, eg, \verb|\textsc{\textup{a}}| has the same effect as \verb|\textup{a}|, producing the letter {\tt a} in upright, not small cap, style. With {\tt fontaxes}, \verb|\textsc{\textup{a}}| produces instead upright small cap {\tt a}. It offers a macro \verb|\textulc| that undoes small caps, so that, eg, \verb|\textsc{\textulc{a}}| produces {\tt a} in non-small cap mode, with whatever other style choices were in force, such as bold or italics.
+
+%\section{Superior figures}
+%The TrueType versions of GaramondNo8 have a full set of superior figures, unlike their PostScript counterparts. The superior figure glyphs in regular weight only have been copied to \texttt{NewG8-sups.pfb} and \texttt{NewG8-sups.afm} and provided with a tfm named \texttt{NewG8-sups.tfm} that can be used by the \textsf{superiors} package to provide adjustable footnote markers. See \textsf{superiors-doc.pdf} (you can find it in \TeX Live by typing \texttt{texdoc superiors} in a Terminal window.) The simplest invocation is
+%\begin{verbatim}
+%\usepackage[supstfm=NewG8-sups]{superiors}
+%\end{verbatim}
+\section*{Glyphs in TS1 encoding}
+The layout of the TS1 encoded Text Companion font, which is rendered \emph{in regular style only}, is as follows. 
+
+\fonttable{ETbb-Regular-tosf-ts1}
+
+
+\textbf{List of macros to access the TS1 symbols in text mode:}\\
+%(Note that slots 0--12 and 26--29 are accents, used like \verb|\t{a}| for a tie accent over the letter a. Slots 23 and 31 do not contain visible glyphs, but have heights indicated by their names.)

+There is a macro \verb|\textcircled| that may be used to construct a circled version of a single letter using \verb|\textbigcircle|. The letter is always constructed from the small cap version, so, in effect, you can only construct circled uppercase letters: \verb|\textcircled{M}| and \verb|\textcircled{m}| have the same effect, namely~\textcircled{M}.
+
+\section*{Usage with fontspec}
+Because the package supplies a file named {\tt ETbb.fontspec} whose contents list the {\tt otf} files that correspond to each of Regular, Bold, Italic and BoldItalic, you may load {\tt ETbb} with just
+\begin{verbatim}
+\usepackage{fontspec}
+\setmainfont{ETbb}
+\end{verbatim}
+Other than the usual choices of figure style, the only remaining choice available is through {\tt StylisticSet=2}, which substitutes the new Sharp S glyphs in place of the familiar \ss, \SS\ and \textsc{\ss}. See the table in the next section for details.
+
+\section*{Selection of the new Sharp S in LaTeX}
+There is now an {\tt ETbb} option {\tt sharpS} whose effect in legacy LaTeX is summarized below.

+%\section{Historical Background}
+%Humanist scholar Pietro Bembo, a seminal figure in literature and music of the Italian Renaissance, who later became Cardinal Bembo, wrote an essay in the last decade of the 15th century about his travels to Mt.\ Aetna, which work was published by the Venetian printer Aldus Manutius (whose name gave us \emph{Aldine}) using a new Roman font designed by his punch-cutter, Francesco Griffo that improved on the earlier efforts of Jenson, another printer in Venice. That font seems to have played a similarly seminal r\^ole in  typography. It was the direct progenitor of the many Garamond fonts, and has seen numerous modern revivals whose names make use of every known historical connection to the figures named above, such as Lucrezia Borgia who was for several years Bembo's  lover.
+%
+%The metal form of the Bembo font developed by Stanley Morison for English Monotype in the 1920's was widely used in book printing due to its handsome appearance and readability. Commercial digital versions have not had much love from critics until recently.  Adobe's MinionPro and WarnockPro arguably deserve the prizes for the best modern revivals of oldstyle fonts not too distant from Bembo. (Both lack Bembo's tall ascenders and its characteristic overarching f.)
+%twoone free source for a Bembo--like font family, one being David Perry's \emph{Cardo} (a contraction of \emph{Cardinal Bembo}), which is not readily accessible to 
+%\LaTeX\ users and which lacks Bold Italic as well as a full range of Small Caps and figure styles. The other is Edward Tufte 
+
+ 
+ 
+% On screen and paper, {\tt ETbb} appears close in weight to Libertine, though of greater  ascender height and slightly less plain.  The following two sentences are written in {\tt ETbb} and Libertine respectively. The third example sentence is written using {\tt garamondx}, whose natural xheight is comparable to Libertine, but which should normally be scaled down to resemble more familiar Garamonds. Perhaps {\tt ETbb} will be prove to be more suitable for older eyes.
+%
+%\textit{\textsc{Comparison between ETbb and Libertine}}: 
+%
+%Both ETbb and Libertine are highly readable fonts in their standard Roman forms, each has a wide range of figures and small caps, but Libertine has the advantage in the number of supported scripts and the variety of weights.

+\section*{Detailed comparison with {\tt fbb}}
+The following picture, in which the units are approximately in {\tt bp}, 
+shows some of the differences between {\tt ETbb-Regular} and {\tt fbb-Regular}, the first scaled up by 10 and the second by 9.8 so that their x-heights (and Cap-heights) are the same. From the picture below you can note the following.
+\begin{itemize}
+\item
+The serifs are much more substantial in {\tt ETbb}.
+\item The ascenders a considerably higher in {\tt fbb}---in fact, by 50 em units. Those very tall ascenders make for poor positioning of quotes, superscripts and the like.
+\item Stems are a little thicker (by about 10\%) in {\tt ETbb}.
+\item There is a slight bowing out in the letter h and similar letters like n of {\tt ETbb} that is not present in {\tt fbb}, making for more visual interest, IMO. This would not be of any importance at small print sizes.
+\item Overall, {\tt ETbb} has lower contrast (ratio of thickest to thinnest strokes) than {\tt fbb}, making for a more uniform gray appearance on the printed page.
+\end{itemize}

+The following page presents a comparison of a {\tt ETbb} and {\tt fbb} with identical text rendered in two columns. For me, there is no question that {\tt ETbb} is the preferable font for document text.
