 This package, based on txfonts, provides many fixes and enhancements to the txfonts package, splitting it into two separate packages---newtxtext and newtxmath, which may be run independently of one another. It provides scaling, improved metrics, and other options. In particular, newtxmath offers a libertine option which substitutes Linux Libertine (provided with TeXLive and MikTeX) italic and Greek letters for the default Times letters, providing a good match for the Libertine text font, which is heavier than Computer Modern but lighter than Times, and in my experience, looks very sharp and clear on the screen.

+Changes in version 1.14
+1. Many changes to largesymbols. There is a new option bigdelims which changes the default versions of the delimiters to ones that are bigger at the two smallest sizes, and more distinct.
+2. Modified definitions of integrals to conform to amsmath option intlimits.
+3. The package amsmath is now required, and is loaded by newtxmath, if necessary.
+4. Substantial changes to lettersA, adding a number of new glyphs for the bigdelims option.

 Changes in version 1.13
 1. Provides alternate versions of some math symbols. See newtxdoc.pdf for details.
 2. Corrected behavior of scaled in newtxmath.

+\section{Introduction}
+This file adds some information updating the information in {\tt implementation.pdf}, showing the relationships between the various forms of math fonts. For simplicity, we discuss only regular weight fonts---there is for each a corresponding bold weight constructed in the same way. Font constructed for use with scriptstyle (7{\tt pt}) and scriptscriptstyle (5{\tt pt}) are also ignored, as their construction was adequately described in {\tt implementation.pdf}. Likewise, we ignore the variant triggered by {\tt varg}, which is indicated by the $1$ appended near the end of the math font name.
+
+The math fonts used in these packages are of the following families:
+\begin{itemize}
+\item [operators] (\verb|\fam0|) is a copy of the Roman text font;
+\item
+[letters] (\verb|\fam1|---OML encoding, 7-bit (128 characters)) containing the math italic Roman and mathematical Greek italic letters, among others;
+\item [symbols] (\verb|\fam2|---OMS encoding, 7-bit (128 characters)) containing most common mathematical symbols;
+\item [largesymbols] (\verb|\fam3|---sometimes OMX encoding, 7-bit (128 characters), sometimes LMX encoding, 8-bit (256 characters)) containing extensible delimiters and large mathematical symbols;
+\item [lettersA] (unencoded 8-bit (256 characters)) with upright Greek, Gothic and assorted symbols;
+\item [AMSa] (unencoded 8-bit (256 characters)) with replacements for the AMSA characters;
+\item [AMSb] (unencoded 8-bit (256 characters)) with replacements for the AMSB characters;
+\item [symbolsC] (unencoded--8-bit (256 characters)) containing less common mathematical symbols;
+\item [largesymbolsA] (unencoded--8-bit (256 characters)) containing less common extensible or large mathematical symbols.
+\end{itemize}
+The options you choose affect only {\tt letters}, {\tt lettersA} and {\tt largesymbols}, and these are the only ones discussed below.
+
+\textsc{Letters}:
+\begin{itemize}
+\item {\tt newtx}:
+\begin{itemize}
+\item The default is Times Roman and Greek italic shapes---{\tt ntxmi};
+\item {\tt minion} uses Roman and Greek italic shapes taken from MinionPro---{\tt zmnmi};
+\item {\tt garamondx} uses Times italic Greek plus Roman italic shapes taken from garamondx---{\tt zgmmi};
+\item {\tt libertine} uses Roman and Greek italic shapes taken from libertine---{\tt nxlmi}.
+\end{itemize}
+\item {newpx}:
+\begin{itemize}
+\item The default is Palatino (clone)  Roman and Greek italic shapes---{\tt npxmi};
+\end{itemize}
+\end{itemize}
+
+\textsc{LettersA}:\\
+Among other unique glyphs, this also contains variant forms for other characters such as small delimiters.
+\begin{itemize}
+\item {\tt newtx}:
+\begin{itemize}
+\item The default is Times Greek upright shapes---{\tt ntxmia};
+\item {\tt minion} substitutes Greek upright shapes taken from MinionPro---{\tt zmnmia};
+\item {\tt libertine} substitutes Greek upright shapes taken from libertine---{\tt nxlmia}.
+\end{itemize}
+\item {\tt newpx}:
+\begin{itemize}
+\item The default is Palatino (clone)  Greek upright shapes---{\tt npxmia};
+\end{itemize}
+\end{itemize}
+
+\textsc{Largesymbols}:\\
+The glyphs don't depend on the font options but do on the option {\tt bigdelims}. OMX encoding is not used for this family, in favor of an LMX-(un)encoded 8-bit math extension.
+\begin{itemize}
+
+\item {\tt newtx}:
+\begin{itemize}
+\item The LMX-(un)encoded 8-bit math extension brings in new glyphs mainly from   {\tt txex-bar}, {\tt ntxexb} and {\tt ntxsyralt}, and goes by the name {\tt ntxexx}.
+\end{itemize}
+\item {\tt newpx}:
+\begin{itemize}
+\item The LMX-(un)encoded 8-bit math extension  goes by the name {\tt npxexx}, constructed by scaling up {\tt ntxexx}.

 \section{Introduction}
 The {\tt txfonts} package by Young Ryu has been available for over ten years but has been corrected very little since its introduction. It is meant to be a complete text and math package with roman text font provided by Times or a Times clone, sans serif based on a \textsf{Helvetica} clone, typewriter faces, plus math symbol fonts whose math italic letters are from a Times Italic clone. The additional glyphs, whether taken from free sources or designed by him, are generally of high quality, but the accompanying metrics are not, making the math inconsistently spaced, but at times so cramped that neighboring symbols  collide.
 
-The goal of this new project is use his glyphs along with a few additions and with completely reworked metrics which are generally looser, but not as loose as Computer Modern math, to make a math package that works with not only Times, but also with fonts that are intermediate in weight between Computer Modern and Times. The free font Linux Libertine is one particular target---it is of nearly the same x-height as Computer Modern, but, not being a \emph{modern} font, does not have a high contrast ratio, and so appears  denser than Computer Modern but not as much so as Times. It is meant as a replacement for Times, but  differs from it in many characteristics, more similar to MinionPro than Times, and provides a better range of variants than Times---three weights (regular, semi-bold and bold) rather than just two, and has expert features in all weights: old-style figures, more extensive and more interesting ligatures,  and  small caps. In my opinion, material typeset in Linux Libertine looks better than the corresponding material typeset in Times. This seems especially true on the screen. As of version 1.0, the package also offers support for MinionPro as a math font, but with limitations described in detail below.

 \item {\tt uprightGreek} and {\tt slantedGreek} determine the form of Greek alphabet loaded---the default is {\tt uprightGreek}, which loads upright uppercase and slanted lowercase Greek symbols, as is customary in Anglo-American mathematical typesetting. With the option {\tt slantedGreek}, which you might want to use if you cared about ISO standards, all Greek symbols are slanted. No matter which is set, \verb|\Gammaup| (or \verb|\upGamma|) gives you upright \verb|\Gamma|, etc.
-\item The option {\tt cmbraces} instructs {\tt newtxmath} to ignore the brace collections from {\tt txfonts}, substituting a collection based on thickened versions of the Computer Modern braces, which I find much easier to distinguish from other delimiters. This works quite well in regular weight but looks a bit clunky in bold.

This works quite well in regular weight but looks a bit clunky in bold. I now prefer the option {\tt bigdelims}, which supersedes {\tt cmbraces}.
 \item The \textsf{newtxmath} package contains three different Blackboard Bold alphabets, where original \textsf{txfonts} contained two. The default, triggered by \verb|\mathbb{}|, takes its glyphs from the font which replaces {\tt msbm} and has the same overall appearance of a hollowed-out text font, which I find neither bold nor blackboard-like. The second option, taken from \textsf{txfonts}, is triggered by \verb|\varmathbb{}|, is more geometric and, in my opinion, preferable but not optimal. The option {\tt varbb} makes \verb|\mathbb{}| synonymous with \verb|\varmathbb{}|. The third option is the double-struck glyphs from the STIX collection. See the expanded discussion below.
 \item {\tt nosymbolsc} causes the package to not load the {\tt symbolsC} fonts, saving  a math family. (This font contains mostly exotic symbols, along with some very useful, commonly used symbols like \verb|\coloneq| $\coloneq$, \verb|\eqcolon| $\eqcolon$, \verb|\notin| $\notin$, \verb|\notni| $\notni$, \verb|\neq| $\neq$, \verb|\nsubset| $\nsubset$ and \verb|\nsupset| $\nsupset$, but these have been moved (virtually) to {\tt lettersA} so they may continue to be used even if you use the option {\tt nosymbolsc}.)
 \item {\tt amssymbols} (the default) and {\tt noamssymbols} determine whether the {\tt txfonts} versions of the \textsc{ams} symbols ({\tt msam}, {\tt msbm}) are loaded---if so, they override previous settings in {\tt amsmath}. If you use the option {\tt noamssymbols}, then \verb|\mathbb{}| is set to mean the same as \verb|\varmathbb{}|. (One advantage of {\tt noamssymbols} is that you save two of your precious math families for other purposes, such as setting a couple of external math alphabets by means of the \textsf{mathalfa} package.)
 \item {\tt libaltvw} has effect only if the libertine option is selected---in this case, it substitutes for math italic v and w hand-crafted versions based on the Libertine upsilon glyphs.
-\item {largelibfigs} has effect only if the libertine option is selected---with this option, full-sized figures are substituted in math mode for the default Libertine figures, which are about 8\% below Libertine's Capheight.
+\item{\tt bigdelims} loads a different math extension font and redefines most of the small and big math delimiters to have larger sizes so that, for example, there is more of a distinction between \verb|(| and \verb|\big(| in math mode. If this option is specified, {\tt cmbraces} is ignored.

 The font files {\tt ntxexmods.pfb} and {\tt ntxbexmods.pfb} were derived from {\tt cmex10.pfb} by FontForgery, thickening the Computer Modern braces to match the weight of the \textsf{txfonts} braces. The pair {\tt ntxexb.pfb} and {\tt ntxbexb.pfb} were similarly derived from {\tt cmsy7.pfb} and {\tt cmex10.pfb} to produce more braces and matching integral signs based on Computer Modern. The {\tt.tfm} files {\tt rtx[b]mio.tfm} are simply unslanted versions of {\tt rtxmi}, from which we construct upright partial derivative symbols.
 The last two entries provide us with a way to access custom-encoded versions of {\tt fxlri.pfb} and {\tt fxlbi.map} in order to access some of the unencoded alternate characters---eg, Greek letters, {\tt J.alt} and {\tt v.alt}. The font file \textsf{LibertineTheta-Regular.pfb} was created from the Theta symbol in {\tt fxlri.pfb}, which requires some FontForge help to look correct.
