+\section{Introduction}
+
+The \texttt{PX} fonts consist of
+\begin{enumerate}\itemsep=0pt
+\item virtual text roman fonts using Adobe Palatino (or URWPalladioL) with
+      some modified and additional text symbols in the OT1, T1, and TS1 encoding
+      %, 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}
+      (Provided in the \texttt{TX} fonts distribution)
+\item \texttt{monospaced typewriter fonts in OT1, T1, TS1, and LY1 encodings}
+      (Provided in the \texttt{TX} fonts distribution)
+\item math alphabets using Adobe Palatino (or URWPalladioL)
+      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{PX} 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{PX} fonts are distributed under the GNU public license (GPL)\@.
+The fonts will be improved and additional glyphs will be added
+in the future.
+
+\section{Requirements}
+
+Since \textsf{sans serif fonts based on Adobe Helvetica (or URW NimbusSanL)}
+and \texttt{monospaced typewriter fonts} of the \texttt{TX} fonts are to be
+used with the \texttt{PX} fonts, one must get and properly install
+the \texttt{TX} fonts, which are available from CTAN
+(or \verb|www.utdallas.edu/~ryoung/txfonts|).
+

+\end{description}
+
+\section{A Problem: \texttt{DVIPS} Partial Font Downloading}
+
+It was reported that when \texttt{PX} 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.}
+
+\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\pxr\
+     \localtexmf\fonts\tfm\pxr\
+     \localtexmf\fonts\vf\pxr\
+     \localtexmf\fonts\type1\pxr\
+\end{verbatim}
+The 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\pxr\
+\end{verbatim}
+Put the \texttt{pxr.map}, \texttt{pxr1.map}, and \texttt{pxr2.map} %, and \texttt{tx8r.enc}
+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{pxr2.map} in
+the \texttt{dvips} configuration file (\texttt{config.ps})
+\begin{verbatim}
+     . . .
+     % Configuration of postscript type 1 fonts:
+     p psfonts.map
+     p +pxr2.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 +pxr2.map
+     . . .
+\end{verbatim}
+(The \texttt{pxr.map} file has only named references to the Adobe Palatino fonts;
+the \texttt{pxr1.map} file makes \texttt{dvips} load Adobe Palatino font files;
+and the \texttt{pxr2.map}  file makes \texttt{dvips} load URWPalladioL font files.)
+Be sure to get URWPalladioL fonts included in the recent Ghostscript
+distribution and properly install them in your \texttt{texmf} tree.
+If you have the real Adobe Palatino font files, put
+\texttt{pxr1.map} instead of \texttt{pxr2.map} in
+\texttt{dvips} and PDF\TeX\ configuration files.
+
+\section{Using the \texttt{PX} Fonts with \LaTeX}
+
+It is as simple as
+\begin{verbatim}
+     \documentclass{article}
+     \usepackage{pxfonts}
+
+     \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{PX} Math Fonts}
+
+\emph{All} CM symbols are included in the \texttt{PX} math fonts.
+In addition, the \texttt{PX} math fonts provide or modify
+the following symbols, including all of \AmS\ and most of \LaTeX\ symbols.
+

+\section{Remarks}
+
+\subsection{Some Font Design Issues}
+
+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{PX} fonts include the negation slash symbol
+(\texttt{"36} in pxsy), 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{PX} fonts.
+
+Further, in order to maintain editing compatibility with
+vanilla \LaTeXe\ typesetting, \verb|\not| is redefined in \texttt{pxfonts.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{PX} 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{Glyph Hinting}
+
+The hinting of the \texttt{PX} fonts is far from ideal.
+As a result, when documents with the \texttt{PX} 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{PX} 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{PX} 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{PX} 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{PX} 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{PX} 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{PX} math fonts include those exactly corresponding to them.
+In addition, the \texttt{PX} math fonts include math italic A,
+math symbols C, and math extension A fonts.
+
