% \begin{abstract}
%   Inconsolata is a monospaced font designed by Raph Levien.
%   It is already available via the \pkg{inconsolata} package.
%   However, that package provides a pretty old version of the font;
%   Additionally, the Nerd Font project extended the font by a huge amount of
%   additional glyphs.
%   This package provides the font itself
%   and a convenient interface to load the font for the
%   \XeLaTeX{} and \LuaLaTeX{} engines.

%
% \section{User Manual}\label{sec:doc}
%
% The Inconsolata font is a monospaced font designed by Raph Levien.
% Its current version is available from the Google Fonts project.\footnote{%
%   \href{https://github.com/googlefonts/Inconsolata}{github.com/googlefonts/Inconsolata}
% }
% There exists an extension of this font by the Nerd Font project,\footnote{%
%   \href{https://www.nerdfonts.com/}{www.nerdfonts.com/}
% }
% which adds a huge amount of additional glyphs,
% especially useful for developers,
% to the original font.
% The extended version is available from GitHub.\footnote{
%   \href{https://github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/InconsolataLGC}{github.com/ryanoasis/nerd-fonts/tree/master/patched-fonts/InconsolataLGC}
% }
% This package provides the TrueType font files
% and a convenient way to use the font
% with the \XeTeX{} or \LuaTeX{} engines.
%
% This user guide gives a brief introduction into the possibilities
% provided by the \pkg{inconsolata-nerd-font} package.
%
% \changes{v0.4}{2023-12-08}{Change variant to have bold-italic and italic glyphs, too}
% Since version 0.4, \pkg{inconsolata-nerd-font} ships and uses the extended
% version of the Inconsolata font, called \emph{InconsolataLGC}.
% This variant also contains Hellenic and Cyrilic glyphs, as well as bold-italic
% and italic variants.

%
% \subsection{Helper Macros}\label{sec:doc-helper}
%
% The following macro is not strictly part of the package.
% It is actually defined by recent \LaTeX{} kernels.
% However, to make the package compatible with older kernels, too,
% we provide it, if it is not yet defined.
%
% The macro's purpose is to check whether the used \LaTeX{} format
% is at least from the given date
% and allows to execute code depending on the result of the check.
% \begin{function}{\IfFormatAtLeastTF}
%   \begin{syntax}
%     \cs{IfFormatAtLeastTF} \marg{date} \marg{true} \marg{false}
%   \end{syntax}
%   We define this macro to execute code depending on the \LaTeX{} format date.
%   The macro is only defined if it is not already part of the \LaTeX{} kernel,
%   which it is for recent versions of the kernel.
% \end{function}
%
% \subsection{Package Arguments}\label{sec:doc-arguments}
%
% The \pkg{inconsolata-nerd-font} package provides the following
% load-time options.
% \begin{variable}{variant}
%   \begin{syntax}
%     variant = \meta{choice}
%   \end{syntax}
%   Specifies which variant of the font shall be used, must be one of
%   |default|, |mono|, or |propo|, where |default| is the default value.
%
%   The |mono| variant is limited to only mono-spaced characters,
%   the |default| variant provides bigger icons (around 1.5 times the width of a
%   normal character),
%   the |propo| variant provides proportional symbols,
%   which might be suitable, e.g., for presentations.
% \end{variable}
%
% \begin{variable}{scale, Scale}
%   \begin{syntax}
%     scale = \marg{factor}
%     Scale = \marg{factor}
%   \end{syntax}
%   Set the scaling of the font.
%   See the \pkg{fontspec} documentation for more details.
%   The default value is |MatchLowercase| to match the height of the lower-case
%   character of the default main font of your document.
% \end{variable}
%
% \subsection{Font Macros}\label{sec:doc-macros}
%
% While the package sets the default mono-spaced font
% to the selected variant of the Inconsolata Nerd Font,
% the package provides six additional macros for convenience,
% one pair of each variant of the font.
%
% \begin{function}{\inconsolatanffamily}
%   \begin{syntax}
%     \cs{inconsolatanffamily}
%   \end{syntax}
%   A font family for the Inconsolata Nerd Font,
%   the default variant provided by this package.
% \end{function}
% \begin{function}{\inconsolatanfmonofamily}
%   \begin{syntax}
%     \cs{inconsolatanfmonofamily}
%   \end{syntax}
%   A font family for the Inconsolata Nerd Font,
%   the mono variant provided by this package.
% \end{function}
% \begin{function}{\inconsolatanfpropofamily}
%   \begin{syntax}
%     \cs{inconsolatanfpropofamily}
%   \end{syntax}
%   A font family for the Inconsolata Nerd Font,
%   the propo variant provided by this package.
% \end{function}
%
% \begin{function}{\textinconsolatanf}
%   \begin{syntax}
%     \cs{textinconsolatanf} \marg{text}
%   \end{syntax}
%   A convenience macro to typeset a short |text| using the default
%   Inconsolata Nerd Font variant.
% \end{function}
% \begin{function}{\textinconsolatanfmono}
%   \begin{syntax}
%     \cs{textinconsolatanfmono} \marg{text}
%   \end{syntax}
%   A convenience macro to typeset a short |text| using the mono
%   Inconsolata Nerd Font variant.
% \end{function}
% \begin{function}{\textinconsolatanfpropo}
%   \begin{syntax}
%     \cs{textinconsolatanfpropo} \marg{text}
%   \end{syntax}
%   A convenience macro to typeset a short |text| using the propo
%   Inconsolata Nerd Font variant.
% \end{function}
%
% The following sentence uses the \cs{textinconsolatanf}
% to typeset the words \enquote{an example} using Inconsolata Nerd Font:
% Just \textinconsolatanf{an example} sentence.
%
% \section{Font Tables}\label{sec:doc-font-tables}
%
% \changes{v0.3}{2023-09-13}{Add font tables to the documentation.}
