+An encoding mistake in Math Italic fonts (txmi and txmi1) fixed.
+That is, "5E and "5F were accidentally switched.
+This patch corrects the mistake.
+
+Properly place enclosed tfm and vf files.
+
+Also properly place enclosed document files.

+\section{Introduction}
+
+The \texttt{TX} fonts consist of
+\begin{enumerate}\itemsep=0pt
+\item virtual text roman fonts using Adobe Times (or URW NimbusRomNo9L) with
+      some modified and additional text symbols in OT1, T1, TS1, and LY1 encodings
+\item \textsf{virtual text sans serif fonts using Adobe Helvetica (or URW NimbusSanL) with
+      additional text symbols in OT1, T1, TS1, and LY1 encodings}
+\item \texttt{monospaced typewriter fonts in OT1, T1, TS1, and LY1 encodings}
+\item math alphabets using Adobe Times (or URW NimbusRomNo9L)
+      with modified metrics
+\item math fonts of all symbols corresponding to those of Computer Modern
+      math fonts (CMSY, CMMI, CMEX, and Greek letters of CMR)
+\item math fonts of all symbols corresponding to those of AMS fonts
+      (MSAM and MSBM)
+\item additional math fonts of various symbols
+\end{enumerate}
+%
+All fonts are in the Type 1 format (in \texttt{afm} and \texttt{pfb} files).
+Necessary \texttt{tfm} and \texttt{vf} files together with
+\LaTeXe\ package files and font map files for \texttt{dvips} are
+provided.
+
+\begin{bfseries}%\itshape
+The \texttt{TX} fonts and related files are distributed 
+without any guaranty or warranty.
+I do not assume responsibility for any actual or possible
+damages or losses, directly or indirectly caused by the
+distributed files.

+\section{Changes}
+
+\begin{description}
+\item[1.0] (October 25, 2000) 1st public release
+\item[2.0] (November 2, 2000)
+     \begin{itemize}
+     \item An encoding error in txi and txbi (`\textdollar' \texttt{"24}) is fixed.
+     \item Mistakes in symbol declarations for `\AA' and `\aa' in \texttt{txfonts.sty}
+           are fixed.
+     \item $\lambda$ (\texttt{"15} of txmi and txbmi),
+           $\lambdaslash$ (\texttt{"6E} of txsyc and txbsyc), and
+	 $\lambdabar$ (\texttt{"6F} of txsyc and txbsyc)
+	 are updated to be more slanted.
+     \item More symbols added in txexa and txbexa (\texttt{"29}--\texttt{"2E})
+           and in txsyc and txbsyc (\texttt{"80}--\texttt{"94}).
+     \item Some fine tuning of a few glyphs.
+     \item Math italic font metrics are improved.
+     \item Text font metrics are improved.
+     \item T1 and TS1 encodings are supported. (Not all TS1 encoding glyphs are implemented.)
+     \end{itemize}
+\item[2.1] (November 18, 2000)
+     \begin{itemize}
+     \item Complete implementation of TS1 encoding fonts.
+     \item Various improvements of font metrics and font encodings. For instance,
+           the bogus entry of char \texttt{'27} in T1 encoding virtual font files
+           are removed. (This bogus entry caused ``warning char 23 replaced
+           by \bs.notdef'' with PDF\TeX/PDF\LaTeX.)
+     \item Helvetica-based TX sans serif fonts in OT1, T1, and TS1 encodings.
+     \item Monospaced TX typewriter fonts, which are thicker than Courier (and thus may look better
+           with Times), in OT1, T1, and TS1 encodings.
+     \end{itemize}
+\item[2.2] (November 22, 2000)
+     \begin{itemize}
+     \item LY1 encoding support
+     \item Monospaced typewriter fonts redone (Uppercase letters are tall enough to match with Times.)
+     \item Various glyph and metric improvement
+     \end{itemize}
+\item[2.3] (December 6, 2000)
+     \begin{itemize}
+     \item Math extension fonts (radical symbols) updated
+     \item Alternative blackboard bold letters ($\varmathbb{A}\ldots\varmathbb{Z}$ and $\varBbbk$)
+           introduced. (Enter \verb|$\varmathbb{...}$| and \verb|$\varBbk$| to get them.)
+     \item More large operators symbols
+     \item Now \verb|\lbag| ($\lbag$) and \verb|\rbag| ($\rbag$) are
+          delimiters.
+     \item Alternative math alphabets $\varg$ and $\vary$ added
+     \end{itemize}
+\item[2.4] (December 12, 2000)
+     \begin{itemize}
+     \item An encoding mistake in text companion typewriter fonts fixed
+     \item Bugs in \LaTeX\ input files fixed
+     \end{itemize}
+\item[3.0] (December 14, 2000)
+     \begin{itemize}
+     \item Minor problem fixes.
+     \item Manual fine-tuning of Type 1 font files
+     \end{itemize}
+\item[3.1] (December 15, 2000)
+     \begin{itemize}
+     \item Alternative math alphabets $\varv$ and $\varw$ added
+     \item Hopefully, this is the final release \ldots
+     \end{itemize}

+\section{A Problem: \texttt{DVIPS} Partial Font Downloading}
+
+It was reported that when \texttt{TX} fonts
+are partially downloaded with \texttt{dvips},
+some HP Laserprinters (with Postscript) cannot
+print documents. To resolve this problem,
+turn the partial font downloading off.
+See the \texttt{dvips} document for various ways to
+turn off partial font downloading.
+
+\textbf{\itshape Even though one does not observe such a problem,
+I would like to strongly recommend to turn off \texttt{dvips}
+partial font downloading.}
+%I think the \texttt{dvips} partial font downloading
+%mechanism appears to have some problems. For instance,
+%when Adobe Times fonts are set to be downloaded, e.g.,
+%\begin{verbatim}
+%   ptmr8r Times-Roman "TeXBase1Encoding ReEncodeFont" <8r.enc <tir_____.pfb

+\section{Installation}
+
+Put all files in \texttt{afm}, \texttt{tfm}, \texttt{vf},
+and \texttt{pfb} files in proper locations of your \TeX\ system.
+For Mik\TeX, they may go to
+\begin{verbatim}
+     \localtexmf\fonts\afm\txr\
+     \localtexmf\fonts\tfm\txr\
+     \localtexmf\fonts\vf\txr\
+     \localtexmf\fonts\type1\txr\
+\end{verbatim}
+All files of the \texttt{input} directory must
+be placed where \LaTeX\ finds its package files.
+For Mik\TeX, they may go to
+\begin{verbatim}
+     \localtexmf\tex\latex\txr\
+\end{verbatim}
+Put the \texttt{txr.map}, \texttt{txr1.map}, \texttt{txr2.map}, and \texttt{tx8r.enc}%
+\footnote{The \texttt{tx8r.enc} file is identical to \texttt{8r.enc}.
+I included \texttt{tx8r.enc} because (1)~some \TeX\ installation might not have \texttt{8r.enc} and
+(2)~including \texttt{8r.enc} would result in multiple copies of \texttt{8r.enc} for \TeX\ systems
+that already have it. \texttt{xdvi} users may do global search-and-replacement of \texttt{tx8r.enc}
+by \texttt{8r.enc} in the \texttt{map} files.}
+files of the \texttt{dvips}
+directory in a proper place that \texttt{dvips} refers to.
+For Mik\TeX, they may go to
+\begin{verbatim}
+     \localtexmf\dvips\config\
+\end{verbatim}
+Also add the reference to \texttt{txr.map} in
+the \texttt{dvips} configuration file (\texttt{config.ps})
+\begin{verbatim}
+     . . .
+     % Configuration of postscript type 1 fonts:
+     p psfonts.map
+     p +txr.map
+     . . .
+\end{verbatim}
+and in the PDF\TeX\ configuration file (\texttt{pdftex.cfg})
+\begin{verbatim}
+     . . .
+     % pdftex.map is set up by texmf/dvips/config/updmap
+     map pdftex.map
+     map +txr.map
+     . . .
+\end{verbatim}
+(The \texttt{txr.map} file has only named references to the Adobe Times fonts;
+the \texttt{txr1.map} file makes \texttt{dvips} load Adobe Times font files;
+and the \texttt{txr2.map}  file makes \texttt{dvips} load URW NimbusRomNo9L font files.)
+
+For \texttt{dvipdfm} users, \texttt{txr3.map} (by Dan Luecking)
+is included. Read comments in the beginning of the file.
+
+\section{Using the \texttt{TX} Fonts with \LaTeX}
+
+It is as simple as
+\begin{verbatim}
+     \documentclass{article}
+     \usepackage{txfonts}
+     %\normalfont                     % Just in case ...
+     %\usepackage[T1]{fontenc}        % To use T1 encoding fonts
+     %\usepackage[LY1]{fontenc}       % To use LY1 encoding fonts
+     %\usepackage{textcomp}           % To use text companion fonts
+
+     \begin{document}
+
+     This is a very short article.
+
+     \end{document}
+\end{verbatim}
+
+The standard \LaTeX\ distribution does not include
+files supporting the LY1 encoding.
+One needs at least \texttt{ly1enc.def}, which is available
+from both CTAN and Y\&Y (\texttt{www.yandy.com}).
+At the time this document was written, CTAN had
+an old version (1997/03/21 v0.3); \texttt{ly1enc.def}
+available from Y\&Y's downloads site was dated on 1998/04/21 v0.4.
+

+In order to replace math alphabets $g$, $v$, $w$, and $y$ by these alternatives,
+use the \texttt{varg} option with the \texttt{txfonts} package:
+\begin{verbatim}
+     \usepackage[varg]{txfonts}
+\end{verbatim}
+Then, \verb|$g$|, \verb|$v$|, \verb|$w$|, and \verb|$y$| will produce
+these $\varg$, $\varv$, $\varw$, and~$\vary$ (instead of $g$, $v$, $w$, and~$y$).
+%
+Notice that $\varv$ (the alternative \textit{v})
+is more clearly distingiushed from $\nu$ (the lowercase Greek nu).
+However, this is not without cost:

+
+%\footnote{A comment on Times New Roman fonts:
+%the italic \textit{v} of Times New Roman (both Type 1 and TrueType versions),
+%but not that of Times, is very badly designed. The starting serif at the left-top
+%corner of the letter is very different from other letters' corresponding portion.
+%However, that of Times New Roman bold italic is consistent with others.
+%Further, in the TrueType version of Times New Roman italic and bold italic,
+%the lowercase Greek $\nu$ (nu) is exactly same as \textit{v} (i.e., linked to \textit{v}).
+%For the mathematical typesetting purpose, this is undesirable.
+%In \texttt{TX} fonts, the lowercase Greek $\nu$ (nu) is not identical to
+%\textit{v}, but very similar. The alternative $\varv$ is provided to
+%be more clearly distingiushed from the lowercase Greek $\nu$ (nu).

+\section{Remarks}
+
+\subsection{Some Font Design Issues}
+
+The Adobe Times fonts are thicker than the CM fonts.
+Designing math fonts for Times based on the rule thickness of Times
+`$=$', `$-$', `$+$', `/', `$<$', etc.\
+would result in too thick math symbols,
+in my opinion.\footnote{I have designed many math symbols
+(corresponding to those in CMMI and CMSY)
+based on the rule thickness of original Times `$=$', etc.
+At that time, I noticed that the symbols,
+especially some bold math symbols, are extremely thick.
+Perhaps, in the future, I will complete all math symbols
+based on the rule thickness of original Times `$=$', etc.\
+and release in public, so that users will judge
+whether they are acceptable or not~\ldots.}
+In the \texttt{TX} fonts, these glyphs are thinner
+than those of original Times fonts. That is, the rule thickness
+of these glyphs is around 85\% of that of the Times fonts,
+but still thicker than that of the CM fonts.
+
+For negated relation symbols, the CM fonts composes
+relation symbols with the negation slash (\texttt{"36} in CMSY).
+Even though the CM fonts were very carefully designed
+to look reasonable when negated relation symbols are composed
+(except `$\notin$' \verb|\notin|, which is composed of
+`$\in$' and the normal slash `$/$'),
+the AMS font set includes many negated relation symbols,
+mainly because the vertical placement and
+height\slash depth of the negation slash are not optimal
+when composed with certain relation symbols, I guess.
+The \texttt{TX} fonts include the negation slash symbol
+(\texttt{"36} in txsy), which could be composed with
+relation symbols to give reasonably looking negated related symbols.
+I believe, however, explicitly designed negated relation symbols
+are looking better than composed relation symbols.
+Thus, in addition to negated relation symbols matching those of
+the AMS fonts, many negated symbols such as `$\neq$' are introduced
+in the \texttt{TX} fonts.
+
+Further, in order to maintain editing compatibility with
+vanilla \LaTeXe\ typesetting, \verb|\not| is redefined in \texttt{txfonts.sty} 
+so that when \verb|\not\XYZ| is processed,
+if \verb|\notXYZ| or \verb|\nXYZ| is defined, it will be used
+in place of \verb|\not\XYZ|; otherwise,
+\verb|\XYZ| is composed with the negation slash.
+For instance, `$\nprecsim$' is available as \verb|\nprecsim| in the \texttt{TX} fonts.
+Thus, if \verb|\not\precsim| is typed in the document,
+the \verb|\nprecsim| symbol, instead of \verb|\precsim| composed
+with the negation slash, is printed.
+
+\subsection{Times vs.\ Times New Roman}
+
+The recent version of Acrobat is shipped with
+Times New Roman instead of Times fonts.
+Times New Roman fonts' italic letters (e.g.,
+`\textit{A}') are substantially different from those
+of Times fonts. Thus, when documents with the \texttt{TX} fonts
+are processed with Acrobat, accents may not be correctly placed.
+If this is a noticeable problem, use the NimbusRomNo9L fonts
+(included in the Ghostscript distribution) with the \texttt{TX} fonts
+through \texttt{txr2.map}.
+
+\subsection{PDF\TeX/PDF\LaTeX\ and Standard Postscript Fonts}
+
+PDF\TeX/PDF\LaTeX\ does not handle slanting of fonts not embedded
+in the document.
+Note, in the standard setup, PDF\TeX/PDF\LaTeX\ does not embed
+the 14 standard Postscript fonts (Times $\times$~4,
+Helvetica $\times$~4, Courier $\times$~4, Symbol, and ZapfDingbats).
+As the result, PDF\TeX/PDF\LaTeX\ issues warning
+(and may try to generate and use bitmapped fonts for these fonts).
+If it is not desirable, a solution would be to use URW NimbusRomNo9L
+and NimbusSanL fonts
+which are an Adobe Times and Helvetica fonts clone. That is, in the
+PDF\TeX/PDF\LaTeX\ configuration file (\texttt{pdftex.cfg}),
+put \texttt{txr2.map} instead of \texttt{txr.map}
+\begin{verbatim}
+     . . .
+     % pdftex.map is set up by texmf/dvips/config/updmap
+     map pdftex.map
+     map +txr2.map
+     . . .
+\end{verbatim}
+Be sure to properly install URW NimbusRomNo9L and NimbusSanL fonts (which are
+included in the Ghostscript distribution) in your texmf tree.
+
+If you have Adobe Times and Helvetica font files, and want to embed them
+in your PDF document file, do the following trick to fool PDF\TeX/PDF\LaTeX.
+\begin{enumerate}\itemsep=0pt%\parskip=0pt
+\item Copy \texttt{txr1.map} in the dvips configuration directory
+      to \texttt{txrpdf.map} in the PDF\TeX/PDF\LaTeX\ configuration directory.
+\item Edit txrpdf.map and have
+\begin{small}
+\begin{verbatim}
+rtxptmb "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tib_____.pfb
+rtxptmbo ".167 SlantFont TeXBase1Encoding ReEncodeFont" <tx8r.enc <tib_____.pfb
+rtxptmbi "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tibi____.pfb
+rtxptmr "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tir_____.pfb
+rtxptmro ".167 SlantFont TeXBase1Encoding ReEncodeFont" <tx8r.enc <tir_____.pfb
+rtxptmri "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tii_____.pfb
+. . .
+\end{verbatim}
+\end{small}
+instead of
+\begin{small}
+\begin{verbatim}
+rtxptmb Times-Bold "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tib_____.pfb
+. . .
+. . .
+\end{verbatim}
+\end{small}
+Note, the actual standard Postscript fonts names such as \texttt{"Times-Bold"}
+are removed. As the result, PDF\TeX/PDF\LaTeX\ will embed these standard
+Postscript fonts and there will be no warning for slanting them.
+\item Put \texttt{txrpdf.map} in the PDF\TeX/PDF\LaTeX\ configuration
+      file (\texttt{pdftex.cfg}).
+\begin{small}
+\begin{verbatim}
+. . .
+% pdftex.map is set up by texmf/dvips/config/updmap
+map pdftex.map
+map +txrpdf.map
+. . .
+\end{verbatim}
+\end{small}
+\end{enumerate}
+
+\subsection{Glyph Hinting}
+
+The hinting of the \texttt{TX} fonts is far from ideal.
+As a result, when documents with the \texttt{TX} fonts
+are \emph{viewed} with Gsview (or Ghostview), you might notice
+some display quality problem. When they are \emph{viewed}
+with Acrobat, they look much better.
+However, when they are \emph{printed} in laser printers,
+there will be no quality problem.
+(Note, hinting is to improve display quality on low resolution devices such as
+display screens.)
+
+\subsection{Glyphs in Low Positions}
+
+It is known that Acrobat often does not properly handle
+CM font glyphs placed between \texttt{"00} and \texttt{"1F}.
+Thus, most Type 1 versions of CM fonts publicly available
+have these glyphs in higher positions above \texttt{"7F}.
+When the \texttt{-G} flag is used with \texttt{dvips},
+those glyphs in low positions are shifted to higher positions.
+The \texttt{TX} text fonts have
+glyphs in the low positions between \texttt{"00} and \texttt{"1F}.
+As of now, these glyphs are not available in higher positions above \texttt{"7F}.
+Thus, when run \texttt{dvips}, do not use the \texttt{-G}
+flag (or remove \texttt{G} in the \texttt{dvips} configuration file).
+Especially, do not use \texttt{config.pdf}.
+In my computer systems, Acrobat correctly handles glyphs in low positions.
+However, if this known Acrobat problem occurs in other computer systems,
+I will modify the \texttt{TX} fonts so that glyphs in low positions
+are also available in higher positions.
+
+\section{Font Charts}
+
+The original Computer Modern (CM) text fonts (aka \TeX\ text fonts)
+have the OT1 encoding. The OT1 \texttt{TX} text fonts follow
+the CM fonts' encoding as much as possible, but have some
+variations and additions:
+\begin{itemize}\parskip=0pt\itemsep=0pt
+\item The position \texttt{"24} of text italic fonts has
+      the dollar symbol (\textit{\textdollar}), not the sterling symbol (\textit{\textsterling}).
+\item The uppercase and lowercase lslash (\L, \l) and aring (\AA, \aa) letters are added.
+\item The cent (\ifx\textcentoldstyle\undefined\textcent\else\textcentoldstyle\fi)
+      and sterling (\textsterling) symbols are added.
+\end{itemize}
+The original CM text fonts have somewhat different encodings in
+\textsc{cap \& small cap} and \texttt{typewriter} fonts.
+\texttt{TX} fonts corresponding to them have the original CM encodings,
+not the strict OT1 encoding.
+
+The T1 encoding text fonts (known as EC fonts) are designed to
+replace the CM text fonts in the OT1 encoding.
+The LY1 encoding is another text font encoding, which is based
+on both \TeX\ and ANSI encodings.
+Both T1 and LY1 encoding fonts are especially useful to typeset
+European languages with proper hyphenation.
+The TS1 encoding text companion fonts (known as TC fonts) have
+additional text symbols.
+All corresponding \texttt{TX} fonts are implemented.
+
+The Computer Modern (CM) math fonts (aka \TeX\ math fonts)
+consist of three fonts: math italic (CMMI), math symbols (CMSY), and
+math extension (CMEX). The American Mathematical Society provided
+two additional math symbol fonts (MSAM and MSBM).
+The \texttt{TX} math fonts include those exactly corresponding to them.
+In addition, the \texttt{TX} math fonts include math italic A,
+math symbols C, and math extension A fonts.
+
+
+\subsection{OT1 (CM) Encoding Text Fonts}
+
+These fonts' encodings are identical to those of corresponding CM fonts,
+except 6~additional glyphs.

+\section{Introduction}
+
+The \texttt{TX} fonts consist of
+\begin{enumerate}\itemsep=0pt
+\item virtual text roman fonts using Adobe Times (or URW NimbusRomNo9L) with
+      some modified and additional text symbols in OT1, T1, TS1, and LY1 encodings
+\item \textsf{virtual text sans serif fonts using Adobe Helvetica (or URW NimbusSanL) with
+      additional text symbols in OT1, T1, TS1, and LY1 encodings}
+\item \texttt{monospaced typewriter fonts in OT1, T1, TS1, and LY1 encodings}
+\item math alphabets using Adobe Times (or URW NimbusRomNo9L)
+      with modified metrics
+\item math fonts of all symbols corresponding to those of Computer Modern
+      math fonts (CMSY, CMMI, CMEX, and Greek letters of CMR)
+\item math fonts of all symbols corresponding to those of AMS fonts
+      (MSAM and MSBM)
+\item additional math fonts of various symbols
+\end{enumerate}
+%
+All fonts are in the Type 1 format (in \texttt{afm} and \texttt{pfb} files).
+Necessary \texttt{tfm} and \texttt{vf} files together with
+\LaTeXe\ package files and font map files for \texttt{dvips} are
+provided.
+
+\begin{bfseries}%\itshape
+The \texttt{TX} fonts and related files are distributed 
+without any guaranty or warranty.
+I do not assume responsibility for any actual or possible
+damages or losses, directly or indirectly caused by the
+distributed files.
+\end{bfseries}
+The \texttt{TX} fonts are distributed under the GNU public license (GPL)\@.
+The fonts will be improved and additional glyphs will be added
+in the future.

+\section{Changes}
+
+\begin{description}
+\item[1.0] (October 25, 2000) 1st public release
+\item[2.0] (November 2, 2000)
+     \begin{itemize}
+     \item An encoding error in txi and txbi (`\textdollar' \texttt{"24}) is fixed.
+     \item Mistakes in symbol declarations for `\AA' and `\aa' in \texttt{txfonts.sty}
+           are fixed.
+     \item $\lambda$ (\texttt{"15} of txmi and txbmi),
+           $\lambdaslash$ (\texttt{"6E} of txsyc and txbsyc), and
+	 $\lambdabar$ (\texttt{"6F} of txsyc and txbsyc)
+	 are updated to be more slanted.
+     \item More symbols added in txexa and txbexa (\texttt{"29}--\texttt{"2E})
+           and in txsyc and txbsyc (\texttt{"80}--\texttt{"94}).
+     \item Some fine tuning of a few glyphs.
+     \item Math italic font metrics are improved.
+     \item Text font metrics are improved.
+     \item T1 and TS1 encodings are supported. (Not all TS1 encoding glyphs are implemented.)
+     \end{itemize}
+\item[2.1] (November 18, 2000)
+     \begin{itemize}
+     \item Complete implementation of TS1 encoding fonts.
+     \item Various improvements of font metrics and font encodings. For instance,
+           the bogus entry of char \texttt{'27} in T1 encoding virtual font files
+           are removed. (This bogus entry caused ``warning char 23 replaced
+           by \bs.notdef'' with PDF\TeX/PDF\LaTeX.)
+     \item Helvetica-based TX sans serif fonts in OT1, T1, and TS1 encodings.
+     \item Monospaced TX typewriter fonts, which are thicker than Courier (and thus may look better
+           with Times), in OT1, T1, and TS1 encodings.
+     \end{itemize}
+\item[2.2] (November 22, 2000)
+     \begin{itemize}
+     \item LY1 encoding support
+     \item Monospaced typewriter fonts redone (Uppercase letters are tall enough to match with Times.)
+     \item Various glyph and metric improvement
+     \end{itemize}
+\item[2.3] (December 6, 2000)
+     \begin{itemize}
+     \item Math extension fonts (radical symbols) updated
+     \item Alternative blackboard bold letters ($\varmathbb{A}\ldots\varmathbb{Z}$ and $\varBbbk$)
+           introduced. (Enter \verb|$\varmathbb{...}$| and \verb|$\varBbk$| to get them.)
+     \item More large operators symbols
+     \item Now \verb|\lbag| ($\lbag$) and \verb|\rbag| ($\rbag$) are
+          delimiters.

+\section{A Problem: \texttt{DVIPS} Partial Font Downloading}
+
+It was reported that when \texttt{TX} fonts
+are partially downloaded with \texttt{dvips},
+some HP Laserprinters (with Postscript) cannot
+print documents. To resolve this problem,
+turn the partial font downloading off.
+See the \texttt{dvips} document for various ways to
+turn off partial font downloading.
+
+\textbf{\itshape Even though one does not observe such a problem,
+I would like to strongly recommend to turn off \texttt{dvips}
+partial font downloading.}
+%I think the \texttt{dvips} partial font downloading
+%mechanism appears to have some problems. For instance,
+%when Adobe Times fonts are set to be downloaded, e.g.,
+%\begin{verbatim}
+%   ptmr8r Times-Roman "TeXBase1Encoding ReEncodeFont" <8r.enc <tir_____.pfb
+%\end{verbatim}
+%\TeX ing \texttt{testfont.tex} on \texttt{ptmr8r}
+%and \texttt{dvips}ing \texttt{testfont.dvi}
+%with partial font download on give
+%\begin{verbatim}
+%   WARNING: Not all chars found
+%\end{verbatim}
+%This specific warning seems to be harmless. But,
+%in my opinion, this should not happen.
+
+
+\section{Installation}
+
+Put all files in \texttt{afm}, \texttt{tfm}, \texttt{vf},
+and \texttt{pfb} files in proper locations of your \TeX\ system.
+For Mik\TeX, they may go
+\begin{verbatim}
+     \localtexmf\fonts\afm\txr\
+     \localtexmf\fonts\tfm\txr\
+     \localtexmf\fonts\vf\txr\
+     \localtexmf\fonts\type1\txr\
+\end{verbatim}
+All files of the \texttt{input} directory must
+be placed where \LaTeX\ finds its package files.
+For Mik\TeX, they may go
+\begin{verbatim}
+     \localtexmf\tex\latex\txr\
+\end{verbatim}
+Put the \texttt{txr.map}, \texttt{txr1.map}, \texttt{txr2.map}, and \texttt{tx8r.enc}%
+\footnote{The \texttt{tx8r.enc} file is identical to \texttt{8r.enc}.
+I included \texttt{tx8r.enc} because (1)~some \TeX\ installation might not have \texttt{8r.enc} and
+(2)~including \texttt{8r.enc} would result in multiple copies of \texttt{8r.enc} for \TeX\ systems
+that already have it.}
+files of the \texttt{dvips}
+directory in a proper place that \texttt{dvips} refers to.
+For Mik\TeX, they may go
+\begin{verbatim}
+     \localtexmf\dvips\config\
+\end{verbatim}
+Also add the reference to \texttt{txr.map} in
+the \texttt{dvips} configuration file (\texttt{config.ps})
+\begin{verbatim}
+     . . .
+     % Configuration of postscript type 1 fonts:
+     p psfonts.map
+     p +txr.map
+     . . .
+\end{verbatim}
+and in the PDF\TeX\ configuration file (\texttt{pdftex.cfg})
+\begin{verbatim}
+     . . .
+     % pdftex.map is set up by texmf/dvips/config/updmap
+     map pdftex.map
+     map +txr.map
+     . . .
+\end{verbatim}
+(The \texttt{txr.map} file has only named references to the Adobe Times fonts;
+the \texttt{txr1.map} file makes \texttt{dvips} load Adobe Times font files;
+and the \texttt{txr2.map}  file makes \texttt{dvips} load URW NimbusRomNo9L font files.)
+
+\section{Using the \texttt{TX} Fonts with \LaTeX}
+
+It is as simple as
+\begin{verbatim}
+     \documentclass{article}
+     \usepackage{txfonts}
+     %\normalfont                     % Just in case ...
+     %\usepackage[T1]{fontenc}        % To use T1 encoding fonts
+     %\usepackage[LY1]{fontenc}       % To use LY1 encoding fonts
+     %\usepackage{textcomp}           % To use text companion fonts
+
+     \begin{document}
+
+     This is a very short article.
+
+     \end{document}
+\end{verbatim}
+
+The standard \LaTeX\ distribution does not include
+files supporting the LY1 encoding.
+One needs at least \texttt{ly1enc.def}, which is available
+from both CTAN and Y\&Y (\texttt{www.yandy.com}).
+At the time this document was written, CTAN had
+an old version (1997/03/21 v0.3); \texttt{ly1enc.def}
+available from Y\&Y's downloads sites was dated on 1998/04/21 v0.4.
+
+\section{Additional Symbols in the \texttt{TX} Math Fonts}

+\emph{All} CM symbols are included in the \texttt{TX} math fonts.
+In addition, the \texttt{TX} math fonts provide or modify
+the following symbols, including all of AMS and most of \LaTeX\ symbols.

+In order to replace math alphabets $g$, $v$, $w$, and $y$ by these alternatives,
+use the \texttt{varg} option with the \texttt{txfonts} package:
+\begin{verbatim}
+     \usepackage[varg]{txfonts}
+\end{verbatim}
+Then, \verb|$g$|, \verb|$v$|, \verb|$w$|, and \verb|$y$| will produce
+these $\varg$, $\varv$, $\varw$, and~$\vary$ (instead of $g$, $v$, $w$, and~$y$).
+%
+Notice that $\varv$ (the alternative \textit{v})
+is more clearly distingiushed from $\nu$ (the lowercase Greek nu).
+However, this is not without cost:
+it looks similar to $\upsilon$ (the lowercase Greek upsilon).
+
+%\footnote{A comment on Times New Roman fonts:
+%the italic \textit{v} of Times New Roman (both Type 1 and TrueType versions),
+%but not that of Times, is very badly designed. The starting serif at the left-top
+%corner of the letter is very different from other letters' corresponding portion.
+%However, that of Times New Roman bold italic is consistent with others.
+%Further, in the TrueType version of Times New Roman italic and bold italic,
+%the lowercase Greek $\nu$ (nu) is exactly same as \textit{v} (i.e., linked to \textit{v}).
+%For the mathematical typesetting purpose, this is undesirable.
+%In \texttt{TX} fonts, the lowercase Greek $\nu$ (nu) is not identical to
+%\textit{v}, but very similar. The alternative $\varv$ is provided to
+%be more clearly distingiushed from the lowercase Greek $\nu$ (nu).
+%The alternative $\varw$ is provided to ensure consistency.}

+\section{Remarks}
+
+\subsection{Some Font Design Issues}
+
+The Adobe Times fonts are thicker than the CM fonts.
+Designing math fonts for Times based on the rule thickness of Times
+`$=$', `$-$', `$+$', `/', `$<$', etc.\
+would result in too thick math symbols,
+in my opinion.\footnote{I have designed many math symbols
+(corresponding to those in CMMI and CMSY)
+based on the rule thickness of original Times `$=$', etc.
+At that time, I noticed that the symbols,
+especially some bold math symbols, are extremely thick.
+Perhaps, in the future, I will complete all math symbols
+based on the rule thickness of original Times `$=$', etc.\
+and release in public, so that users will judge
+whether they are acceptable or not~\ldots.}
+In the \texttt{TX} fonts, these glyphs are thinner
+than those of original Times fonts. That is, the rule thickness
+of these glyphs is around 85\% of that of the Times fonts,
+but still thicker than that of the CM fonts.
+
+For negated relation symbols, the CM fonts composes
+relation symbols with the negation slash (\texttt{"36} in CMSY).
+Even though the CM fonts were very carefully designed
+to look reasonable when negated relation symbols are composed
+(except `$\notin$' \verb|\notin|, which is composed of
+`$\in$' and the normal slash `$/$'),
+the AMS font set includes many negated relation symbols,
+mainly because the vertical placement and
+height\slash depth of the negation slash are not optimal
+when composed with certain relation symbols, I guess.
+The \texttt{TX} fonts include the negation slash symbol
+(\texttt{"36} in txsy), which could be composed with
+relation symbols to give reasonably looking negated related symbols.
+I believe, however, explicitly designed negated relation symbols
+are looking better than composed relation symbols.
+Thus, in addition to negated relation symbols matching those of
+the AMS fonts, many negated symbols such as `$\neq$' are introduced
+in the \texttt{TX} fonts.
+
+Further, in order to maintain editing compatibility with
+vanilla \LaTeXe\ typesetting, \verb|\not| is redefined in \texttt{txfonts.sty} 
+so that when \verb|\not\XYZ| is processed,
+if \verb|\notXYZ| or \verb|\nXYZ| is defined, it will be used
+in place of \verb|\not\XYZ|; otherwise,
+\verb|\XYZ| is composed with the negation slash.
+For instance, `$\nprecsim$' is available as \verb|\nprecsim| in the \texttt{TX} fonts.
+Thus, if \verb|\not\precsim| is typed in the document,
+the \verb|\nprecsim| symbol, instead of \verb|\precsim| composed
+with the negation slash, is printed.
+
+\subsection{Times vs.\ Times New Roman}
+
+The recent version of Acrobat is shipped with
+Times New Roman instead of Times fonts.
+Times New Roman fonts' italic letters (e.g.,
+`\textit{A}') are substantially different from those
+of Times fonts. Thus, when documents with the \texttt{TX} fonts
+are processed with Acrobat, accents may not be correctly placed.
+If this is a noticeable problem, use the NimbusRomNo9L fonts
+(included in the Ghostscript distribution) with the \texttt{TX} fonts
+through \texttt{txr2.map}.
+
+\subsection{PDF\TeX/PDF\LaTeX\ and Standard Postscript Fonts}
+
+PDF\TeX/PDF\LaTeX\ does not handle slanting of fonts not embedded
+in the document.
+Note, in the standard setup, PDF\TeX/PDF\LaTeX\ does not embed
+the 14 standard Postscript fonts (Times $\times$~4,
+Helvetica $\times$~4, Courier $\times$~4, Symbol, and ZapfDingbats).
+As the result, PDF\TeX/PDF\LaTeX\ issues warning
+(and may try to generate and use bitmapped fonts for these fonts).
+If it is not desirable, a solution would be to use URW NimbusRomNo9L
+and NimbusSanL fonts
+which are an Adobe Times and Helvetica fonts clone. That is, in the
+PDF\TeX/PDF\LaTeX\ configuration file (\texttt{pdftex.cfg}),
+put \texttt{txr2.map} instead of \texttt{txr.map}
+\begin{verbatim}
+     . . .
+     % pdftex.map is set up by texmf/dvips/config/updmap
+     map pdftex.map
+     map +txr2.map
+     . . .
+\end{verbatim}
+Be sure to properly install URW NimbusRomNo9L and NimbusSanL fonts (which are
+included in the Ghostscript distribution) in your texmf tree.
+
+If you have Adobe Times and Helvetica font files, and want to embed them
+in your PDF document file, do the following trick to fool PDF\TeX/PDF\LaTeX.
+\begin{enumerate}\itemsep=0pt%\parskip=0pt
+\item Copy \texttt{txr1.map} in the dvips configuration directory
+      to \texttt{txrpdf.map} in the PDF\TeX/PDF\LaTeX\ configuration directory.
+\item Edit txrpdf.map and have
+\begin{small}
+\begin{verbatim}
+rtxptmb "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tib_____.pfb
+rtxptmbo ".167 SlantFont TeXBase1Encoding ReEncodeFont" <tx8r.enc <tib_____.pfb
+rtxptmbi "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tibi____.pfb
+rtxptmr "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tir_____.pfb
+rtxptmro ".167 SlantFont TeXBase1Encoding ReEncodeFont" <tx8r.enc <tir_____.pfb
+rtxptmri "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tii_____.pfb
+. . .
+\end{verbatim}
+\end{small}
+instead of
+\begin{small}
+\begin{verbatim}
+rtxptmb Times-Bold "TeXBase1Encoding ReEncodeFont" <tx8r.enc <tib_____.pfb
+. . .
+. . .
+\end{verbatim}
+\end{small}
+Note, the actual standard Postscript fonts names such as \texttt{"Times-Bold"}
+are removed. As the result, PDF\TeX/PDF\LaTeX\ will embed these standard
+Postscript fonts and there will be no warning for slanting them.
+\item Put \texttt{txrpdf.map} in the PDF\TeX/PDF\LaTeX\ configuration
+      file (\texttt{pdftex.cfg}).
+\begin{small}
+\begin{verbatim}
+. . .
+% pdftex.map is set up by texmf/dvips/config/updmap
+map pdftex.map
+map +txrpdf.map
+. . .
+\end{verbatim}
+\end{small}
+\end{enumerate}
+
+\subsection{Glyph Hinting}
+
+The hinting of the \texttt{TX} fonts is far from ideal.
+As a result, when documents with the \texttt{TX} fonts
+are \emph{viewed} with Gsview (or Ghostview), you might notice
+some display quality problem. When they are \emph{viewed}
+with Acrobat, they look much better.
+However, when they are \emph{printed} in laser printers,
+there will be no quality problem.
+(Note, hinting is to improve display quality on low resolution devices such as
+display screens.)
+
+\subsection{Glyphs in Low Positions}
+
+It is known that Acrobat often does not properly handle
+CM font glyphs placed between \texttt{"00} and \texttt{"1F}.
+Thus, most Type 1 versions of CM fonts publicly available
+have these glyphs in higher positions above \texttt{"7F}.
+When the \texttt{-G} flag is used with \texttt{dvips},
+those glyphs in low positions are shifted to higher positions.
+The \texttt{TX} text fonts have
+glyphs in the low positions between \texttt{"00} and \texttt{"1F}.
+As of now, these glyphs are not available in higher positions above \texttt{"7F}.
+Thus, when run \texttt{dvips}, do not use the \texttt{-G}
+flag (or remove \texttt{G} in the \texttt{dvips} configuration file).
+Especially, do not use \texttt{config.pdf}.
+In my computer systems, Acrobat correctly handles glyphs in low positions.
+However, if this known Acrobat problem occurs in other computer systems,
+I will modify the \texttt{TX} fonts so that glyphs in low positions
+are also available in higher positions.
+
+\section{Font Charts}
+
+The original Computer Modern (CM) text fonts (aka \TeX\ text fonts)
+have the OT1 encoding. The OT1 \texttt{TX} text fonts follow
+the CM fonts' encoding as much as possible, but have some
+variations and additions:
+\begin{itemize}\parskip=0pt\itemsep=0pt
+\item The position \texttt{"24} of text italic fonts has
+      the dollar symbol (\textit{\textdollar}), not the sterling symbol (\textit{\textsterling}).
+\item The uppercase and lowercase lslash (\L, \l) and aring (\AA, \aa) letters are added.
+\item The cent (\ifx\textcentoldstyle\undefined\textcent\else\textcentoldstyle\fi)
+      and sterling (\textsterling) symbols are added.
+\end{itemize}
+The original CM text fonts have somewhat different encodings in
+\textsc{cap \& small cap} and \texttt{typewriter} fonts.
+\texttt{TX} fonts corresponding to them have the original CM encodings,
+not the strict OT1 encoding.
+
+The T1 encoding text fonts (known as EC fonts) are designed to
+replace the CM text fonts in the OT1 encoding.
+The LY1 encoding is another text font encoding, which is based
+on both \TeX\ and ANSI encodings.
+Both T1 and LY1 encoding fonts are especially useful to typeset
+European languages with proper hyphenation.
+The TS1 encoding text companion fonts (known as TC fonts) have
+additional text symbols.
+All corresponding \texttt{TX} fonts are implemented.
+
+The Computer Modern (CM) math fonts (aka \TeX\ math fonts)
+consist of three fonts: math italic (CMMI), math symbols (CMSY), and
+math extension (CMEX). The American Mathematical Society provided
+two additional math symbol fonts (MSAM and MSBM).
+The \texttt{TX} math fonts include those exactly corresponding to them.
+In addition, the \texttt{TX} math fonts include math italic A,
+math symbols C, and math extension A fonts.
+
+
+\subsection{OT1 (CM) Encoding Text Fonts}
+
+These fonts' encodings are identical to those of corresponding CM fonts,
+except 6~additional glyphs.
