-% package (or earlier |libertine| version). The typeset

-% If the Libertine fonts (from |legacy| or earlier) are on your

-% font, use |\usepackage[biolinum]{libgreek}|. The Greek
-% letters are made available only in math mode.
+The package \ctanpkg{libertinus-type1} is not loaded, but must be present.
+
+Thus \libgreek is for people who want \emph{only} to adjust Greek letters in math
+mode (and easily configure usage of upright or italic/slanted shapes), perhaps
+in the context of having changed Latin letters as well, e.g.\@ from using the
+\ctanpkg{mathastext} or the \ctanpkg{frenchmath} packages.

+\ctanpkg{libertinust1math}!
+
+
+The Greek letters all come with \cs{...up} and \cs{...it} named variants, and
+whether ``bare'' control sequences map to the `|up|' or `|it|' ones can be
+configured via package options, even midway in the document via
+\cs{libgreeksetup}. Further, the package optionally defines two math
+alphabets \cs{libgreekup} and \cs{libgreekit}. What `|up|' and `|it|'
+actually mean can be configured using the |upshape| and |itshape| keys at
+package loading time.

-% override any |greek| or |Greek|
-% option. The package defaults to |style=TeX|.
-% \item[greek=|value|] specifies the shape (n, it, or sl) for both
-% the lowercase and uppercase Greek letters. So |greek=it| is
-% like |style=ISO|, and |greek=n| is like |style=French|.
-% \item[Greek=|value|] specifies the shape (n, it, or sl)
-% for only the uppercase Greek letters. To have lowercase

-% \item[series=|value|] tells which series to use. The
-% default is the value of \cs{seriesdefault} at the time of

+
+\section{Documentation of the \libgreek package}
+
+Here are the options recognized by the package:
+\begin{description}
+\item[libertinus] This option forces usage of the font support
+ files from package \ctanpkg{libertinus-type1} even if
+ \ctanpkg{libertine-legacy} is avalable on the \LaTeX{} installation.
+\item[serif] Configures the package to use the (type1) Libertinus Serif font. This is
+ the default behaviour (if the ``legacy''
+ mode is not activated).
+\item[libertine] This is a deprecated alias for |serif|, which is provided for
+ backwards compatibility with existing documents and does not inhibit the
+ ``legacy'' mode: on a system having the \ctanpkg{libertine-legacy} files it
+ will end up being handed over to \libgreek-legacy, except if some other
+ option inhibits this.
+\item[sans] Configures the package to use the (type1) Libertinus Sans font.
+\item[biolinum] Configures the package to use either the Libertinus Sans font
+ or the (type1) Biolinum font if the ``legacy'' mode kicks in.
+\item[upshape=\meta{shape}] Declares the shape to be used by the \cs{...up}
+ Greek letters and the \cs{libgreekup} math alphabet. Defaults to `|n|'
+ (without the quotes).
+\item[itshape=\meta{shape}] Declares the shape to be used by the \cs{...it}
+ Greek letters and the \cs{libgreekit} math alphabet. Defaults to `|it|'.
+\item[scale=\meta{factor}] will scale the font by the given
+ factor, relative to nominal size.
+
+ Example: scale=1.2 will scale by 20\%.\DeleteShortVerb{\|}
+\item[style=\meta{\upshape\ttfamily ISO|French|TeX}] specifies the shape style
+ of the Greek letters.\MakeShortVerb{\|}
+
+ |ISO| means `italic' for lowercase
+ and uppercase, |French| means `upright' for lowercase and uppercase, |TeX|
+ means `italic' for lowercase and `upright' for uppercase.
+
+ This option will
+ override any |greek| or |Greek| option. The package defaults to |style=TeX|.
+
+ What `upright' and `italic' mean is configured by the |upshape| and
+ |itshape| respective settings.\DeleteShortVerb\|
+\item[greek=\meta{\ttfamily\upshape up|it|...}] Says\MakeShortVerb{\|} whether
+ Greek letters will be `upright' or `italic' i.e.\@ whether they obey the
+ |upshape| or |itshape| setting, i.e.\@ whether \cs{alpha} et al.\@ are
+ \cs{let} to \cs{alphaup} (et al.) or to \cs{alphait} (et
+ al.).\MakeShortVerb{\|}
+
+ So |greek=it| is like |style=ISO|, and |greek=up| is like |style=French|.
+
+ For backwards compatibility with the behaviour of the 2011 release, other
+ shape values, such as `|n|' and `|sl|' or even `|sc|', are accepted. For
+ more details, see the explanations for |Greek|. For example |greek=n| is
+ like |style=French|.
+
+ This option is ignored if |style| is used (order does not matter).
+ \DeleteShortVerb\|
+\item[Greek=\meta{\ttfamily\upshape up|it|...}] Says\MakeShortVerb{\|}
+ whether uppercase Greek
+ letters (and only them) will be `upright' or `italic' i.e.\@ whether they
+ use |upshape| or |itshape|, i.e.\@ whether \cs{Alpha} et al.\@ are \cs{let}
+ to \cs{Alphaup} (et al.) or to \cs{Alphait} (et al.).\MakeShortVerb{\|}
+
+ So to obtain lowercase to be `upright' and uppercase to be `italic', use
+ |greek=up| and then |Greek=it| (|Greek| must appear after |greek| else it will be
+ shadowed by it). Alternatively, do not use the |greek/Greek| keys but set
+ |upshape=it|, |itshape=n|, as the package by default assigns `italic' to
+ lowercase and `upright' to uppercase.
+
+ This option, like the |greek| option, is ignored if the |style| option is used.
+
+ For backwards compatibility with the behaviour of the 2011 release, other
+ shape values, such as `|n|' and `|sl|', are accepted. They will then
+ override the |upshape| setting for it to match it. For example |Greek=sc|
+ will force |upshape| to be |sc|, because the assumed style is the \TeX{} one
+ of italic lowercase and upright uppercase, so setting the shape of uppercase
+ must update the |upshape| value.
+
+ \DeleteShortVerb{\|}
+ It is however recommended to use rather the \verb+upshape|itshape|style+ keys.
+ \MakeShortVerb{\|}
+
+ Using |greek=up| or |Greek=up| does not inhibit ``legacy'' mode although the
+ legacy package did not a priori accept that value `|up|'. But since
+ \LaTeX{} 2020-02-02, the `|up|' shape is recognized and triggers
+ |up|$\to$|n| substitutions, so one can use that syntax even in contexts
+ which will let the package fall back to ``legacy'' mode. Not recommended, though.
+
+ % Actually |greek| and |Greek| are provided mainly as compatibility stubs with
+ % legacy behaviour, in order for the package, even if not using ``legacy''
+ % mode, to behave similarly regarding shapes as was doing its initial release.
+
+\item[series=\meta{series}] This tells which series to use. The default is the
+ value of \cs{seriesdefault} at the time of loading the package. There is no interface to configure distinct series for the `upright' and `italic' shapes.
+\item[boldseries=\meta{series}] This tells which series to use in bold
+ math. Default is \cs{bfdefault} at the time of loading the package. There is no interface to configure distinct series for the `upright' and `italic' shapes.
+\item[alphabets] Says whether to define \cs{libgreekup} and \cs{libgreekit}.

+\caption[Greek letters via Libertinus Sans (italic)]{Greek letters from LibertinusSans in LGR encoding, italic shapes}
+\label{table:LibertinusSans italic}
+\MakeShortVerb\|
+\end{table}
+
+Here are the commands defined by the package:
+\begin{description}
+\item[\cs{libgreeksetup}\marg{key=value,...}] The only allowed keys are
+ |style|, |greek| and |Greek|. And for the latter two only the values |up|
+ or |it| should be used (or values matching the |upshape| or |itshape|
+ settings), as it is only possible after package loading time to toggle
+ between `upright' and `italic' depending on whether the letter is uppercase
+ or lowercase, but one can not switch to an altogether different shape as
+ this would require re-declaring the symbol fonts.
+
+ If the |style| key is used, then |greek/Greek| are ignored. However,
+ one can always naturally reuse later \cs{libgreeksetup} using only the
+ |greek| and/or |Greek| keys.
+\item[\cs{libgreekup}] This is a math alphabet. It is defined only if the
+ package received the |alphabets| option.
+\item[\cs{libgreekit}] This is a math alphabet. It is defined only if the
+ package received the |alphabets| option.
+\end{description}
+
+Miscellaneous remarks:
+\begin{enumerate}
+\item Even if not receiving the option |alphabets|, the package will declare
+ all Greek letters to be of type \cs{mathalpha}. The legacy package on the
+ other hand declares them all to be of type \cs{mathord}.
+\item The \libgreek package ignores global class options. It handles only
+ options originating from the \cs{usepackage} preamble declaration (or some
+ options handed over via \cs{PassOptionsToPackage} or options passed to
+ \cs{libgreeksetup} in the preamble or body). The \libgreek-legacy package
+ on the other hand handles global class options if it recognizes them.
+\end{enumerate}
+
+\section{Documentation of the \libgreek-legacy package}
+
+Except for a fix to a problem with \cs{varvarsigma} and \cs{varvarkappa}, and
+the handling of option |libertine| (which formerly would have remained
+effectless if used after |biolinum|) \libgreek-legacy is functionally
+equivalent with the original |1.0| release of \libgreek from |2011/03/14|.
+
+Compared to the 2022 \libgreek, and apart from the fact that the legacy mode
+relies on presence of the files of \ctanpkg{libertine-legacy}, the main
+difference is that this legacy version does not define \cs{...up} and
+\cs{...it} shape variants, does not provide \cs{libgreekup} and
+\cs{libgreekit} math alphabets, and does not define a command
+\cs{libgreeksetup} allowing to change the shapes midway in a document. All
+Greek letters are defined as math symbols of type \cs{mathord}, whereas the
+2022 \libgreek uses type \cs{mathalpha}.
+
+Also, the legacy package defines even more
+control sequences for letters with diacritics or special variant
+glyphs, than does the 2022 \libgreek relying on \ctanpkg{libertinus-type1}
+LGR-encoded fonts.
+
+Now to the decription of the recognized options.
+
+With the exception of |libertine| and |biolinum|, all options are of the
+|key=value| type.
+\begin{description}
+\item[libertine] Configures the package to use the (type1) Libertine font
+ (i.e.\@ the serif font). This is the default behaviour.
+\item[biolinum] Configures the package to use the (type1) Biolinum font
+ (i.e.\@ the sans serif font).
+\item[scale=\meta{factor}] will scale the font by the given
+ factor, relative to nominal size (when the
+ Libertine/Biolinum fonts are used elsewhere in the
+ document, they will also be scaled by this
+ factor). Note that the similar option of the
+ \ctanpkg{libertine-legacy} package is called |scaled| and has
+ precisely the same effect. Example: scale=1.2 will
+ scale by 20\%.\DeleteShortVerb{\|}
+\item[style=\meta{\upshape\ttfamily ISO|French|TeX}]
+ specifies the shape of the Greek\MakeShortVerb{\|}
+ letters. |ISO| means italic for lowercase and
+ uppercase, |French| means upright for lowercase and
+ uppercase, |TeX| means italic for lowercase and upright
+ for uppercase. This option will
+ override any |greek| or |Greek|
+ option. The package defaults to |style=TeX|.
+\item[greek=\meta{shape}] specifies the shape (|n|, |it|, or |sl|) for both
+ the lowercase and uppercase Greek letters. So |greek=it| is
+ like |style=ISO|, and |greek=n| is like |style=French|.
+\item[Greek=\meta{shape}] specifies the shape (|n|, |it|, or |sl|)
+ for only the uppercase Greek letters. To have lowercase
+ upright and uppercase italic, use |greek=n,Greek=it|.
+\item[series=\meta{series}] tells which series to use. The
+ default is the value of \cs{seriesdefault} at the time of
+ loading the package. See the \ctanpkg{libertine-legacy} package
+ documentation for the admissible values (they include |m|,
+ |b|, |bx| (=|b|) for Libertine and |m|, |b|, |bx| (=|b|), |o|, |s| for
+ Biolinum).
+\item[boldseries=\meta{series}] tells which series to use in
+ bold math. Default is
+ \cs{bfdefault} at the time of loading the
+ package.
+\end{description}
+\begin{enumerate}[(1)]
+\item the bold italic Greek Libertine glyphs are missing from |libertine v5|
+ and later versions up to |libertine-legacy| (or some bug in the font
+ definition files triggers usage of \TeX{} font files not having the glyphs):
+ the log file will contain ``Missing character'' entries, and the PDF will
+ simply display nothing. With |\tracinglostchars=3| and \TeX Live 2021 or
+ later, these ``Missing character'''s will be reported as build errors by \TeX,
+ as they should. Use bold slanted instead.
+\item the bold lowercase Greek Biolinum letters
+are in fact not bold.
+\end{enumerate}
+
+Advanced example of use (we use slanted rather than italic
+to circumvent the problem mentioned above):
+\begin{verbatim}
+\documentclass{article}
+\usepackage[scale=2,series=b,greek=sl,Greek=n]{libgreek}
+\begin{document}
+$\alpha\beta\gamma\phi\psi \Alpha\Beta\Gamma\Phi\Psi$
+\end{document}
+\end{verbatim}
+
+As shown in the \autoref{table:libertine}, the package also defines control
+sequences to access quite a few letters with diacritics. The displayed glyphs
+correspond to using |libgreek-legacy| with its default, i.e.\@ the serif font
+(Libertine) is used, the lowercase italic letters are italic, and the
+uppercase are upright.

+\section{Release history}
+
+\libgreek was initially developed on a computer equipped with \TeX Live 2010
+and was released on March 14, 2011. It got a documentation update on September 23,
+2012, but its source code and version number 1.0 did not change then.
+
+The initial release used files as included in the v4 version of the
+\ctanpkg{libertine} package then maintained by Michael~\textsc{Niedermair} and
+which allowed traditional non-Unicode \TeX{} engines to access glyphs of the
+Unicode Linux Libertine fonts as designed by Philipp~H.~\textsc{Poll}.
+
+By the time of \TeX Live 2012 (and even earlier), the files needed by \libgreek
+had been moved to the \ctanpkg{libertine-legacy} package (maintained by
+Bob~\textsc{Tennent}). This documentation was updated in September 2012
+to mention this.
+
+But around circa 2018 (I think) \ctanpkg{libertine-legacy} package was moved
+to the ``Obsolete'' section of CTAN, and stopped being included in new \TeX
+Live releases. This means that \ctanpkg{libgreek}, although still included in
+\TeX Live, was actually broken on new installations. Theoretically the user
+could still install \ctanpkg{libertine-legacy}
+manually, but this is not easy
+as it is not distributed as a |.tds.zip| archive on CTAN mirrors, and
+furthermore the |libertine.map| may need to be renamed before being listed in
+some |updmap.cfg| file, else it would clash with the |libertine.map| from the
+current \ctanpkg{libertine} package (maintained by Bob~\textsc{Tennent}, and
+which now can be used on all engines as it auto-detects the context).
+
+This situation, and the fact that the \ctanpkg{libertinus-type1} package
+(also maintained by Bob~\textsc{Tennent}, thanks Bob!) provides support files
+for the LGR encoding, thus allowing to access Greek glyphs, motivated the 2022
+release of \libgreek.
+
+Thanks to Antoine~\textsc{Missier} (author of \ctanpkg{frenchmath}) for making
+the author aware that \libgreek had ceased functioning and was in need of an
+update, and indeed for quite some years already.

+% To minimize the author's task, we keep close to original code with minimal
+% adaptations. In particular I decided to keep the fact that |style| option
+% makes the |Greek| and |greek| options ignored. But there are some
+% complications originating in the addition of the \cs{libgreeksetup}, which
+% requires to keep a trace of various things, for example if |style| option is
+% used at package level and then later on using \cs{libgreeksetup} the user
+% employs the |Greek/greek| options.

+% Although the user interface is kept in a maximally backwards compatible way
+% (i.e.\@{} even if not falling back to ``legacy'' the option behaviour should
+% be stable), the underlying architecture of the symbol fonts is completely
+% different because this package assigns two symbol fonts, one for upright,
+% the other one for italic-like, whereas the legacy package assigns one or two
+% symbol fonts depending on whether lowercase and uppercase letters have been
+% assigned or not the same shape. In the legacy package the symbol fonts are
+% mapped to either lowercase or uppercase, but in this more modern package,
+% the symbol fonts are for the `upright' and `italic' shapes.
%
+% The new |upshape| and |itshape| keys allow to configure what the \cs{...up}
+% and \cs{...it} macros will actually use as shapes.

+% We use the \ctanpkg{keyval} interface mostly to not have to rework
+% everything, if at all possible, into the \ctanpkg{kvoptions} declarative
+% interface. It is a very good thing that the latter package can be used
+% without forcing on the user its own declarative interface... however this
+% means that inputs such as |serif=false| do not generate errors but are
+% handled exactly the same as |serif=true|...

+% Definition of the \cs{mathchar}'s without `|up/it|' postfix. There are 27

+% realized that bold italic had gone missing from the ``8bit'' font support of
+% libertine v5 compared to libertine v4, and was vaguely hoping that going via
+% the LGR encoded font definition files would help, but it did not. I kept
+% the file around, and basically only had to replace the font family name, or
+% so I thought about ten days ago when I started re-examining the matter. But
+% at no point did I go back to check if I had done exhaustive work in 2011 and
+% whether some other glyphs could be accounted for by LGR (I did re-check an
+% old file about the LGR encoding I had from that 2011 work, but did not try
+% to check for updates). Anyway, it is very doubtful whether it made any
