% \begin{abstract}
% 	\noindent\lpack{cfr-lm} offers enhanced support for Latin Modern 2.004 in \TeX/\LaTeX{} on 8-bit engines\footnote{%
%   It is not required, does not support and should not be loaded with Unicode engines.
%   Indeed, it was largely written because I wanted to use features easily accessible on Unicode engines while continuing to compile with pdf\TeX{}, which was significantly more reliable at the time and is still considerably faster.%
% }.
% A number of features of the Latin Modern fonts are not easily accessible via the default \TeX/\LaTeX\ support provided in the official distribution.
% This package aims to provide \TeX/\LaTeX\ support for a number of these features including various styles of digits, upright italic and oblique small-caps shapes, and alternative weights and widths.
% It also supports the variable width typewriter, ‘dunhill’ and ‘quotation’ fonts.
% If \lpack{microtype} is loaded, the package ensures the custom settings designed for Computer and Latin Modern are loaded.

% 
% \section{Introduction}
% 
% This document explains how to use the \lpack{cfr-lm} package to access advanced features of the Latin Modern fonts not otherwise supported by the official \lpack{lm} distribution.
% These features include various styles of digits, upright italic and oblique small-caps italic, alternative weights and widths, and Latin Modern Mono Prop (variable width typewriter), Dunhill and Sans Quotation.
% By default, the \LaTeX\ package provided by \path{cfr-lm.sty} uses proportional oldstyle digits and variable width typewriter but this can be changed by passing appropriate options when loading the package.
% The package also supports using e.g.\ different styles of digits within a document so it is possible to use proportional oldstyle digits by default, say, but tabular lining digits within a particular table.
% Finally, a command to access the zeroslash character is provided.
% 
% \changes{v1.3}{2010/05/27}{%
%   Update for version 2.004 of Latin Modern.%
% }
% \lpack{cfr-lm} version 1.3 requires version 2.004 of \textsc{gust}'s Latin Modern fonts, including the support package provided for \TeX.
% The fonts and \TeX\ support are included in many \TeX\ distributions or may be obtained from \url{http://www.gust.org.pl/projects/e-foundry/latin-modern} or your nearest \ctan{} mirror.
% 
% \lpack{cfr-lm} consists of all files listed in \lpack{manifest.txt}\ and these files are released under the \LaTeX\ Project Public Licence as explained in the included licensing notices.
%
% \changes{v1.3}{2010/05/27}{%
%   Improved option handling due almost entirely to Enrico Gregorio.
%   Improved accent placement for faked glyphs thanks in considerable part to Lars Hellström's patience.
%   Ignore all font dimensions in the \textsc{afm} files and take them from the \textsc{tfm}s released with Latin Modern instead.%
% }
% Version 1.3 of the package benefited greatly from feedback provided by Enrico Gregorio, who essentially rewrote the style file using \lpack{keyval} to show me how I ought to be setting the various options up, and Lars Hellström who demonstrated considerable patience in answering my many questions about using \lpack{fontinst} and some peculiarities of the Latin Modern fonts.
% I hope the changes in the production of the virtual fonts will improve accent placement in ‘faked’ glyphs (i.e.\ in the case of characters not included in the \textsc{ec}/\textsc{t1} font encoding which \TeX\ therefore creates by combining glyphs which are included).
% The changes involve ignoring all font dimensions given in the \textsc{afm} files and taking them from the relevant \textsc{tfm} files supplied with Latin Modern instead.
% The exception to this is the value of \verb|acccapheight| which is set to zero in the \textsc{tfm}s.
% The current virtual font setup uses \lpack{fontinst}'s default value in this case.
% 
% \changes{v1.4}{2014/03/04}{%
%   Use family-specific settings for \lpack{microtype}.%
% }
% If you load \lpack{microtype}, version 1.4 and later will automatically figure out the family-specific settings to use.
% This is done using aliases which tell \lpack{microtype} to treat the virtual fonts provided by this package in the same way it treats Latin Modern and Computer Modern Roman.
% See \fref{sec:mt} for details.
% 
% \section{Requirements}\label{sec:require}
% 
% In addition to the usual suspects (\LaTeX\ etc.), the \LaTeX\ support provided by \path{cfr-lm.sty} requires:
% \begin{itemize}
% 	\item \lpack{lm}: Latin Modern version 2.004\footnote{This package should not be used with any other version of Latin Modern due to likely changes to the font metrics, glyph names etc.}
% 	\item \lpack{nfssext-cfr}
% \end{itemize}
% 
% If you wish to compile (as opposed to read) the package documentation, additional, packages are required.
% See \path{cfr-lm.dtx} for details.
%
% If you wish to recreate the font support files from the base `\lpack{lm}` package, the easiest option is to download the source from \codeberg{} or \github{}.
% You can, however, also recreate the font files by hand using the sources included in the \ctan{} archive alone\footnote{%
%   The font definition files will be functionally equivalent to those included in the package, but the spacing in some \cs{DeclareFontFamily} lines will differ because \lpack{fontinst} doesn't write arguments passed to \cs{installfamily} verbatim to the output stream..
%   Other files should be equivalent modulo commented lines.%
% }.
% 
% \section{Limitations}
% 
% Unlike the official \TeX\ support for Latin Modern, \lpack{cfr-lm} supports only the \textsc{ec}/\textsc{t1} and Text Companion (\textsc{ts1}) encodings for text.
% Also unlike the official support, the \textsc{ec}/\textsc{t1} support depends entirely on virtual fonts.
% If virtual fonts have disadvantages, then, whatever those disadvantages may be, \lpack{cfr-lm} will inherit them.
% This does not apply to the \textsc{ts1} encoding or to mathematics, since these rely purely on the support provided by the official distribution so should be identical.
% 
% \LaTeX{} does not recognise the fonts provided by this package, including the \textsc{ts1} encoding but excluding the mathematics, \emph{as} Latin Modern.
% This is problematic because newer kernels treat Computer Modern and Latin Modern differently, but only if they are accessed using the default names.
% This causes at least two complications.

% First, the kernel responds to \lpack{cfr-lm} far more ‘noisily’ than one would like, especially since the noise is entirely unnecessary.
% The warnings occur because \LaTeX{} switches the default bold series from \texttt{bx} to \texttt{b} unless the document fonts are on a list which includes Latin Modern only by the names provided by \lpack{lmodern}.
% As far as I can tell, the ‘noise’ is merely annoying: the actual fonts used and the final output are unaffected, since the kernel tries \texttt{bx} if \texttt{b} is unavailable, though there is presumably some impact on compilation time.
% In any case, the new version of \lpack{nfssext-cfr} now patches the code the kernel executes at the beginning of the \texttt{document} environment by simply adding the appropriate names to the list of Computer and Latin Modern families.
%
% Second, the virtual fonts provided by this package aren't recognised as supporting the \texttt{ts1} encoding, so \lpack{cfr-lm} needs to specify this specifically on newer kernels\footnote{On older kernels, the package continues to load \lpack{textcomp} as it did before.}.
% 
% \section{Font setup}
% 
% As explained above, the fonts use the \textsc{ec}/\textsc{t1} and Text Companion (\textsc{ts1}) encodings.
% The provision for the \textsc{ts1} and mathematics encodings simply calls the support provided by \lpack{lm}.
% The \lpack{cfr-lm} support simply ensures that access is provided automatically when the \textsc{t1}-encoded virtual fonts it provides are active.
%

% \section{Additional font commands}\label{sec:commands}
% 
% \lpack{cfr=lm}\ loads \lpack{nfssext-cfr}\ which is an extension of the package \lpack{nfssext}\ supplied by Philipp Lehman as part of The Font Installation Guide.
% The file extends the font selection commands to facilitate access to various font features.
% Both the original and the extension are designed for use with a wide range of fonts.
% For this reason, only a subset of the additional commands are relevant to any particular font support package.
% Those relevant to \lpack{cfr-lm}\ are described below.
% 
% \subsection{nfssext-cfr}
% 
% These commands are available when \lpack{cfr-lm}\ is loaded.
% If for some reason you wish to make them available at any other time, use \verb|\usepackage{nfssext-cfr}| in your document preamble.
% 
% Note that only combinations supported by the fonts will appear as expected because the commands will only have an effect if the active font offers the relevant variant.
% For example, trying to switch to a condensed width will have no effect if any of the LM Roman fonts is active.
% This means that only a subset of combinations are possible.
% In other cases,	one of two things should happen.
% First, a ‘silent’ substitution may be made.
% For example, if you request proportional figures while using monowidth typewriter, tabular figures will be silently substituted.
% Second, console messages may warn you that the combination you tried to use isn't available.
% If you request titling while using monowidth 	typewriter, a console message will warn you it was unavailable.
% The file \path{clm-test.tex} gives an idea of what's possible and also serves as an example illustrating some of the commands provided by \lpack{cfr-lm} and other ways of accessing the fonts..

% \DescribeMacro{\regwidth}
% \DescribeMacro{\textrw}
% \DescribeMacro{\cdwidth}
% \DescribeMacro{\textcd}
% Additional macros for changing width are listed in \fref{tab:widths}.
% To switch to an condensed width until further notice, for example, you could use \verb|\cdwidth|.
% Or use \texttt{\cs{texttm}\{\cs{textlg}\{\cs{textcd}\{Hello, world!\}\}\}} to typeset just the text \texttm{\textlg{\textcd{Hello, world!}}} in light-weight condensed monowidth typewriter.
% 
% Note that the easiest way to switch to semi-bold condensed sans is to resort to using \verb|\fontseries| directly.
% \iffalse

% 	\textsf{\fontseries{sbc}\selectfont Semi-bold condensed sans}
% \end{center}
% The problem with using the commands provided by \lpack{nfssext-cfr} is that they are designed, like standard commands such as \verb|\scshape|, to change \emph{one} aspect of the font at a time\footnote{%
%   This is, of course, by design.
%   The problem with using standard commands such as \cs{bfseries} is that they are designed to change \emph{two} aspects of the font at a time i.e.~width and weight.%
% }.
% Issuing \verb|\textsf{\textcd{\textsb{}}}| and \verb|\textsf{\textsb{\textcd{}}}| are equivalent to \verb|\textsf{}| because neither standard-width semi-bold nor condensed normal-weight sans is available.
% The problem is that each command is processed independently, so both switches fail.
% 
% Similar considerations in the case of light condensed monowidth typewriter mean that the \emph{order} in which commands are issued is critical.
% In this case, a light-weight standard-width font is available, but no normal-weight condensed font is provided.
% Consequently,
% \iffalse
%<*verb>
% \fi
%    \begin{verbatim}
\texttm{\textlg{\textcd{a successful switch}}}

%    \end{verbatim}
% \iffalse
%</verb>
% \fi
% will result in \texttm{\textcd{\textlg{an unsuccessful switch}}} and a warning in the log.
% In this case, the latter command is equivalent to \verb|\texttm{\textlg{}}| because \verb|\textcd{}| can only succeed \emph{after} \verb|\textlg{}|.

% 			\texttt{\texto{0123456789}}
% 		\end{center}
% First, note that it is necessary to reissue \verb|\texto{}| after switching to sans or typewriter text.
% This is because both switching to sans or typewriter and switching to another figure style involves a switch of font family\footnote{Compare a switch in width or weight which does not typically involve a change of active font family.}.
% 
% Second, note that the output shows \emph{proportional} oldstyle figures for romand and sans, but \emph{tabular} oldstyle for typewriter, because the command \verb|\texto{}| only changes \emph{one} aspect of the style.
% Because proportional figures were already active for serif and sans, the command switched to proportional oldstyle figures in the first two cases.
% Contrariwise, since tabular figures were active for typewriter, the same command switched to tabular oldstyle figures in the third case.
%
% In many cases, it is convenient to switch or ensure both aspects of digits together e.g.~to ensure tabular lining figures are used in tabulars.

%   See, for example, \href{https://tex.stackexchange.com/q/255709/}{Why shouldn't I use \texttt{getnonfreefonts} to install additional fonts? Why shouldn't I use \texttt{updmap} when installing or removing fonts?}.}
% 
% \section{Installation}
% 
% \textbf{The vast majority of users should IGNORE this section entirely.}
% \lpack{cfr-lm} is included in all major \TeX{} distributions and should be installed as part of your \TeX{} installation.
% Installing the package yourself should be done only as a last resort or an educational exercise.
% 
% Note, in particular, that this version of \lpack{cfr-lm} should \textbf{not} be installed on older \LaTeX{} kernels as it is designed to work with the (New) New Font Selection Scheme, as updated around 2020\footnote{%
%   The package should\texttrademark{} work fine on older kernels, but the new version is bound to have some bugs and there is no reason to use it on these systems.
%   The sole purpose of the update is to accommodate the breaking changes made to font selection.
%   If you don't have those changes installed locally, nothing should be broken and the newer version of \lpack{cfr-lm} offers no advantage at all.%
% }.
% Use the initial release of \lpack{cfr-lm} if your installation of \LaTeX{} predates those changes.
% 
% Installation varies with \TeX\ distribution so you should consult the documentation which came with your system for details.
% In most cases, you will need to perform three steps:
% \begin{enumerate}
%   \item move or copy the package files to appropriate locations on your system;
%   \item refresh the \TeX\ database;
%   \item incorporate the included map file fragments for the different engines your distribution supports.
% \end{enumerate}
% 
% The following instructions assume you are using \TeX~Live\footnote{This includes Mac\TeX\ for OS X users.}. 
% They should not be too difficult to adapt if you are using a different distribution.
% 
% \subsection{Install the files}
% 
% The files should be installed in one of two locations: \emph{either} the local system-wide \TeX\ tree \emph{or} your personal tree.
% If the package is installed system-wide, all users will have access to it.
% On the other hand, you may need privileges you do not have to do this in which case you must use your personal tree.
% 
% \textbf{There are serious disadvantages to installing the package into your personal tree.
% In particular, these pertain to use of \verb|updmap --user| rather than \verb|updmap --sys|.
% If you are not aware of these disadvantages, please ensure you are fully cognisant of them before proceeding\fnupdmap.
% Merely removing the package from your personal tree at a later point will \emph{not} undo the effects.}
% 
% For \TeX~Live, \verb|kpsewhich -var-value TEXMFLOCAL| will return the path to the local tree and \verb|kpsewhich -var-value TEXMFHOME| the path to your personal tree. 
% The package already includes a hierarchy of files to help you install them correctly.
% Ignoring any symbolic link in the top directory, move or copy the files in \path{doc}, \path{fonts} and \path{tex} into the appropriate locations.
% If the tree is initially empty, you can simply move or copy the directories in as they are.
% If the tree already contains other packages, you may need to merge the package hierarchy with the pre-existing one.
% For example, if you already have a \path{doc/fonts} directory, move or copy \path{doc/fonts/cfr-lm} into \path{doc/fonts/}.
% If you have a \path{doc} directory but not a \path{doc/fonts}, move \path{doc/fonts} into \path{doc/}.
% 
% \subsection{Refresh the database}
% 
% Again, this depends on your distribution. For \TeX~Live, \verb|mktexlsr <path to directory>| for the directory you used in the first step should do the trick.
% Note that you \emph{may} be able to skip this step if you install into your personal tree.
% Whether this is so depends on the details of your set-up.
% As a test, move to a directory containing none of the package files and try \verb|kpsewhich cfr-lm.sty|.
% If the file is found, you don't need to refresh the database; otherwise use \verb|mktexlsr| and then try again.
% 
% \subsection{Install the map fragments}
% 
% For \TeX~Live, there are at least two ways of doing this. 
% The second method varies according to the version of \TeX~Live and instructions are provided accordingly.
% Both methods depend on whether you installed into \verb|TEXMFLOCAL| or \verb|TEXMFHOME|.
% If you installed system-wide, the choice is relatively straightforward --- it obviously makes sense in that case to update the font maps system-wide as well.
% 
% If, on the other hand, you installed into your personal tree, the matter is more complex. 
% On the one hand, updating the system-wide maps may create difficulties or confusion for other users because while the map files will list the fonts as available, they will not be able to access them.
% On the other hand, maintaining personal font map files can produce difficulties and confusions of its own\fnupdmap.
% Whether it is to be preferred or not is a complex issue and depends on the details of your \TeX\ distribution, local configuration and personal preference. 
% The one clear case is that in which you install into your personal tree because you lack the privileges needed to install system-wide. 
% In that case, you have no choice but to maintain personal font map files or forgo the use of all fonts not provided by your administrator.
% Other cases are thankfully beyond the scope of this document.
% 
% \subsubsection{Method 1}
% 
% If you installed the package system-wide, use the command:
% \iffalse
% ^^A ateb Heiko Oberdiek: https://tex.stackexchange.com/a/172896/
% ^^A dyw hwn ddim yn gweithio tu mewn i arg macro! 
% ^^A (*wrth gwrs* dyw e ddim yn weithio! wyt ti'n *hollol* dwp?)
%<*verb>
% \fi
\begin{verbatim}
updmap-sys --enable Map=clm.map
\end{verbatim}
% \iffalse
%</verb>
% \fi
%
% If you installed the package in your personal tree, you \emph{may} prefer\fnupdmap:
% \iffalse
%<*verb>
% \fi
\begin{verbatim}
updmap --enable Map=clm.map
\end{verbatim}
% \iffalse
%</verb>
% \fi
% Either way, \verb|updmap| will output a good deal of information after each incantation.
% This is normal.
% Just check that it does not end with an error and that it found the new map file.
% 
% \subsubsection{Method 2: \TeX~Live 2008 (and probably earlier)}
% 
% If you installed the package system-wide, use \verb|updmap-sys --edit|.
% 
% If you installed into your personal tree, you \emph{may} prefer to use	\verb|updmap --edit|\fnupdmap.
% 
% Either way, a configuration file will be opened which you can edit.
% Move to the end of the file and add the following line:
% \iffalse
%<*verb>
% \fi
\begin{verbatim}
Map clm.map
\end{verbatim}
% \iffalse
%</verb>
% \fi
% When you are done, save the file.
% \verb|updmap| or \verb|updmap-sys| will produce a great deal of output if all is well. 
% Just check that it does not end with an error and that \path{clm.map} is found.
% 
% \subsubsection{Method 2: \TeX~Live 2009 (and possibly later)}
% 
% If you installed the package system-wide, edit or or create \path{TEXMFLOCAL/web2c/updmap-local.cfg} and add the following line to the end of the file:
% \iffalse
%<*verb>
% \fi
\begin{verbatim}
Map clm.map
\end{verbatim}
% \iffalse
%</verb>
% \fi
% Save the file and tell \verb|tlmgr| to merge in your addition using the command:
% \iffalse
%<*verb>
% \fi
\begin{verbatim}
tlmgr generate updmap
\end{verbatim}
% \iffalse
%</verb>
% \fi
% \verb|tlmgr| will then tell you that you need to ensure the changes are propagated correctly by calling \verb|updmap-sys|. 
% This should produce a great deal of output.
% Check that it finds the new map file and does not end with an error.
% 
% If you installed into your personal tree, you \emph{may} prefer to use \verb|updmap --edit| as described above for \TeX~Live 2008\fnupdmap.
% 
% \subsubsection{Method 3: Current/Recent \TeX~Live}
% 
% If you installed the package system-wide, tell \cs{updmap} to enable the map file:
% \iffalse
%<*verb>
% \fi
\begin{verbatim}
updmap --sys --enable Map=clm.map
\end{verbatim}
% \iffalse
%</verb>
% \fi
% This should produce a great deal of output.
% Check that it finds the new map file and does not end with an error.
% 
% If you installed into your personal tree, you \emph{could} use \verb|updmap --user| in place of \verb|updmap --sys| as described above for \TeX~Live 2008, but this is \textbf{not} recommended\fnupdmap.
% 
% To test your installation and that the package works on your system, latex this file (\path{cfr-lm.tex}).
% The console output and/or log should tell you whether any fonts were not found. 
% If you are careful not to overwrite it, you may also compare your output with \path{cfr-lm.pdf}.%
