+# Math Greek letters - The mathgreeks package
+
+
+## Presentation
+
+The purpose of this package is to provide access to numerous Greek letter fonts
+for math mode, without altering other mathematical characters and symbols
+and without loading whole extensions that provide these fonts.
+Moreover, the chosen font or shape can be changed dynamically throughout the document.
+
+
+## Installation
+
+- run LaTeX on mathgreeks.ins, you obtain the file mathgreeks.sty;
+- if then you run LuaLaTeX on mathgreeks.dtx you get the file mathgreeks.pdf which is also in the archive;
+- if you run pdfLaTex on mathgreeks.dtx you get a shorter version of this pdf file without the examples using fontspec or unicode-math;
+- put the files mathgreeks.sty and mathgreeks.pdf in your TeX Directory Structure.

+% \section{Introduction}
+%
+% The purpose of this package is to provide access to numerous Greek letter fonts
+% for math mode, without altering other mathematical characters and symbols
+% and without loading whole extensions that provide these fonts.
+%
+% The commands "\italpha", "\itbeta"\ldots\ produce the italic forms of the chosen font,
+% and "\upalpha", "\upbeta" \ldots\ produce the upright forms.
+% Style options allow choosing between italic or upright forms for the basic commands
+% "\alpha", "\beta"\ldots
+% Only letters whose glyph differs from the corresponding Roman letter
+% will be defined this way.
+% Therefore, the package does not provide a command "\omicron",
+% whose letter is identical to the Roman `o', and only a few uppercase letters are defined:
+% "\Gamma", "\Delta", "\Theta"\ldots
+%
+% \medskip
+% An ISO recommendation, rarely followed, is to typeset uppercase
+% Greek letters in italic shape, as for other variables~\cite{ICTNS}.
+% This is automatically achieved, for some particular fonts, with packages
+% such as \textsf{fixmath} by Walter Schmidt~\cite{FIXM},
+% \mbox{\textsf{isomath}} by Günter Milde~\cite{ISOM}
+% or \textsf{pm-isomath} by Claudio Beccari~\cite{PMISO} and optionally with some others
+% (such as \textsf{mathpazo} or \textsf{mathptmx} with the option \texttt{slantedGreek}).
+% When running through \LuaLaTeX\ or \XeLaTeX\ you can also get this result
+% with the option \mbox{\texttt{math-style=ISO}} provided
+% by the \textsf{unicode-math} package~\cite{UNIC}.
+%
+% Furthermore there are several packages that provide the uppercase Greek letters
+% in italic and have also options to typeset the lowercase Greek
+% letters in upright shape.
+% Notably, let us mention
+% \mbox{\textsf{mathdesign}}~\cite{DESIGN},
+% \mbox{\textsf{kpfonts}}~\cite{KPF},
+% \mbox{\textsf{fourier}}~\cite{FOUR}, but also
+% \mbox{\textsf{pxgreeks}} (using \textsf{pxfonts}~\cite{PX}), \mbox{\textsf{txgreeks}}
+% (using \textsf{txfonts}~\cite{TX}),
+% \mbox{\textsf{libertinust1math}}~\cite{LIB}, \mbox{\textsf{libgreek}}, etc.
+% A special mention goes to \textsf{lgrmath} of Jean-François Burnol~\cite{LGR}
+% which allows the use of any Greek LGR-encoded font in math mode,
+% an idea taken up in \textsf{mathgreeks}.
+% Also note \textsf{newtxmath}~\cite{NTX} which has several font options.
+% For upright lowercase letters, we have the nice \textsf{upgreek}~\cite{GREEK} package.
+%
+% \medskip
+% The interest of \textsf{mathgreeks} lies in being able to choose the Greek letters font
+% from one of these packages or from a TrueType or OpenType font installed on your computer.
+% The package sets Greek letters in the desired font and shape
+% and enables to change font or shape dynamically within the document.
+%
+% \section{Options and settings}
+%
+% \subsection{Package options}
+%
+% When calling the package, there are three types of options:
+% \begin{itemize}
+% \item Font options,
+% \item Shape options (the style),
+% \item Additional options.
+% \end{itemize}
+% These options use the `\texttt{key=value}' mechanism.
+% When a default value is set, the key can be used without specifying a value
+% (which will then be the default value).
+% Some keys represent booleans with the default value being `\texttt{true}'.
+%
+% \bigskip
+% The first table, in two parts, presents the different keys corresponding to font options,
+% the list of possible values (complete when it is reduced).
+% The default value is indicated in bold, the second part consist in boolean options.
+% Results are presented in section~\ref{examples}.
+%
+% \begin{table}[h]
+% \begin{center}\ttfamily
+% \begin{tabular}{ll}
+% \hline
+% \vstrut{2ex}\normalfont{Option} & \normalfont{Values} \\
+% \hline
+% lgrmath & Alegreya-LF, Cochineal-LF, \textbf{fcm}\ldots \\
+% fontspec & FreeSerif, \textbf{GFS Didot}, Cambria\ldots \\
+% unicode-math & \textbf{Latin Modern Math}, STIX Two Math\ldots \\
+% upgreek & Euler, \textbf{Symbol}, Symbolsmallscale \\
+% mathdesign & Utopia, Garamond, \textbf{Charter} \\
+% kpfonts & \textbf{normal}, light \\
+% \hline
+% \end{tabular}
+% \hspace{1cm}
+% \begin{tabular}{l}
+% \hline
+% \vstrut{2ex}\normalfont{Booleans} \\
+% \hline
+% fourier \\
+% pxfonts \\
+% txfonts \\
+% libertinus \\
+% concrete \\
+% cmbright \\
+% \hline
+% \end{tabular}
+% \end{center}
+% \caption{font options\label{table:font}}
+% \end{table}
+% The \texttt{fontspec} and \texttt{unicode-math} options require loading
+% the corresponding packages, and these can only work when running through
+% \LuaLaTeX\ (or \XeLaTeX).
+% The fontspec option allows for the use of most TrueType or OpenType
+% fonts installed on your computer,
+% those that have Greek letters.
+%
+% When calling "\boldmath" (outside the math environment), you get the letters in bold face,
+% but the command "\mathbf" doesn't work here.
+%
+% \bigskip
+% The second table below presents the shape options. If the shape option
+% is not specified, the italic shape is chosen by default, meaning that the commands
+% "\alpha", "\beta", \ldots, "\Delta", "\Gamma"\ldots will produce the same result
+% as the corresponding "\it"\meta{letter} commands.
+%
+% \begin{table}[h]
+% \begin{center}
+% \begin{tabular}{ll}
+% \hline
+% \vstrut{2ex}\normalfont{Option} & \normalfont{Description} \\
+% \hline
+% \texttt{greekup} & lowercase letters in upright shape \\
+% \texttt{Greekup} & uppercase letters in upright shape \\
+% \texttt{TeX} & lowercase=italic, uppercase=upright \\
+% \texttt{ISO} & lowercase=italic, uppercase=italic \\
+% \texttt{upright} & lowercase=upright, uppercase=upright \\
+% \texttt{style} & possible values: \texttt{TeX}, \texttt{ISO}, \texttt{upright} \\
+% \hline
+% \end{tabular}
+% \end{center}
+% \caption{shape options\label{table:shape}}
+% \end{table}
+%
+% \begin{itemize}
+% \item Except for \texttt{style}, all these options are booleans.
+% \item The \texttt{Greekup} option est initialized to \texttt{true} (corresponding
+% to the \texttt{TeX} style).
+% \item The \texttt{style=ISO} option produces the same result as the simple
+% \texttt{ISO} option, and the same applies to the other two styles
+% (\texttt{TeX}, \texttt{upright}).
+% \item To get lowercase letters in upright shape and uppercase letters in italic,
+% activate \begin{center}\texttt{greekup=true,Greekup=false}.\end{center}
+% \end{itemize}
+%
+% \smallskip
+% The following list presents the additional options, which are also booleans:
+% \begin{description}
+% \item[\texttt{savegreeks}] Saves the letters corresponding to the original commands
+% "\alpha", "\beta"\ldots so that they remain accessible through the commands
+% "\backalpha", "\backbeta"\ldots
+% \item[\texttt{otherfonts}] Allows dynamic font switching (see next section)
+% for later use of \texttt{lgrmath}, \texttt{fourier}, \texttt{libertinus} or \texttt{upgreek}.
+% \item[\texttt{lowercase}] This option is initialized to \texttt{true};
+% \texttt{lowercase=false} allows keeping the original lowercase Greek letters
+% without redefining the commands "\alpha", "\beta"\ldots
+% \item[\texttt{uppercase}] This option is initialized to \texttt{true};
+% \texttt{uppercase=false} allows keeping the original uppercase Greek letters
+% without redefining the commands "\Gamma", "\Delta"\ldots
+% \end{description}
+%
+% \subsection{Dynamic settings commands}
+%
+% There are two command for dynamic settings:
+% \begin{description}
+% \item[] "\setmathgreeks"
+% This command takes a mandatory parameter which is a list of
+% `\texttt{key=value}' settings among the shape options presented
+% in table~\ref{table:shape} (the other options are not usable in this command).
+% This allows modifying these settings in the body of the document,
+% with a global effect, or local if the command is called in an environment
+% or a group (delimited by braces).
+%
+% \item[] "\mathgreeksfont"
+% This command allows modifying the font of Greek letters throughout the document,
+% with a global or local effect.
+% The possible options fall into two categories:
+% \begin{center}
+% \texttt{fontspec}, \texttt{unicode-math}, \\
+% \texttt{enc}, \texttt{fam}, \texttt{series}, \texttt{shape}.
+% \end{center}
+% The \texttt{fontspec} and \texttt{unicode-math} options are identical
+% to those in table~\ref{table:font}.
+% The other previous font options (\texttt{lgrmath}, \texttt{mathdesign}, etc.)\@
+% are not usable in "\mathgreeksfont".
+% However, these fonts can be obtained by specifying the encoding (option \texttt{enc}),
+% family (option \texttt{fam}), series and shape: the New Font Selection Scheme (NFSS).
+% The series defines the `boldness' and has a default value: \texttt{series=m} (medium).
+% For the shape, the default value is \texttt{shape=it};
+% \texttt{enc} and \texttt{fam} have no default value.
+% For example,
+% \begin{center}
+% "\mathgreeksfont{enc=OML,fam=mdbch,shape=n}"
+% \end{center}
+% will produce upright letters from the Charter font provided by \textsf{mathdesign}.
+% For each font option seen previously,
+% the following examples (section~\ref{examples}) indicates
+% the values to give to \texttt{enc}, \texttt{fam}, and \texttt{shape}.
+% The font definition by NFSS attributes will not produce specific commands for italics
+% "\it"\meta{letter} or for upright letters "\up"\meta{letter}.
+% Only the commands "\alpha", "\beta"\ldots will be redefined according to the
+% selected shape.
+%
+% If you use the \texttt{fontspec} or \texttt{unicode-math} option,
+% these second kind of options have no effect.
+%
+% Notice that the encoding obtained by the package font options is faster, moreover
+% the command "\boldmath" doesn't work anymore
+% when changing the font with \texttt{enc}, \texttt{fam} and \texttt{shape},
+% but you can obtain the boldface
+% letters with \texttt{series=b}, or \texttt{series=bx} (bold extended).
+%
+% \end{description}
+%
+% \section{Examples} \label{examples}
+% \begin{description}
+% \item[] "\greektable"
+% The examples in this section are obtained with the "\greektable" command.
+% This command generates a table with two rows: the first contains the lowercase letters
+% obtained with "\alpha", \ldots, "\omega", and the second contains variants
+% "\varepsilon", "\vartheta"\ldots of certain letters as well as the uppercase letters
+% obtained with "\Gamma", "\Delta", \ldots, "\Omega"
+% (for those who differ from their Latin equivalent).
+% \end{description}
+%
+% \subsection{PostScript font options}
+%
+% The \texttt{upgreek} option, as its name suggests, produces only upright letters,
+% and the \texttt{Euler} font does not have the variants "\varrho" and "\varsigma".
+% The \texttt{Symbolsmallscale} font is identical to Symbol but reduced in size by 90\,\%.
+% \texttt{mathdesign=Garamond} yields a virtual font
+% that may not always work.

+% \subsection{The \texttt{lgrmath} option}
+%
+% The \texttt{lgrmath} option, inspired by the eponymous package developed by J.F. Burnol,
+% has a large number of possible values. We present here only a few.
+% The documentation of the \textsf{lgrmath} package~\cite{LGR} explains how
+% to list and consult the fonts available on your distribution with the LGR encoding.
+% One can also consult with profit the documentation of \textsf{cb-fonts}\cite{CB},
+% the Greek fonts of Claudio Beccari.
+%
+% With the \texttt{lgrmath} option, the alternative commands for the variants
+% produce the same glyphs as those of the normal letters except for "\varsigma".
+%
+% We have not presented here the third column previously indicating the values for
+% \texttt{enc}, \texttt{fam}, and \texttt{shape} because, for this entire section,
+% we have \texttt{enc=LGR}, \texttt{fam=\meta{font-name}}, the name of the font presented,
+% and \texttt{shape=it}, for the italic shape, or \texttt{shape=n}, for the upright shape.
+% Example:
+% \begin{center}
+% "\mathgreeksfont{enc=LGR,fam=Alegreya-LF,shape=n}"
+% \end{center}
+%
