+% \makeatmath
+% \smesetsym{symbfup}{A,v}
+% In \LaTeX~typesetting, it is usually the case that one needs to use different variants of a math symbol to clarify the meanings. For example, in linear algebra literature, it is common to use boldfaced symbols to represent vectors, and use normal symbols to represent scalars, which makes equations like @Av=\lambda v@ easier to understand. However, applying these variants by typing |\mathbf|, |\mathrm| commands manually can be daunting. The \thispkg~package aims to provide an automatic and customizable approach for math symbol styling, which eliminates the need to enter style commands repeatedly.
+% \makeatother
+
+%\section{Usage}
+
+%\subsection{Style Configuration}
+
+% \DescribeMacro\smesetsym{<style csname>}{<symbols>}
+
+% The \meta{symbols} given in the form of comma separated list will be styled using \meta{style csname}. In Example \ref{ex:set-style}, the four symbols $A$, $v$, $Q$, and $\Lambda$ will be styled with the command |\symbfup| from the \pkg{unicode-math} package, which produces boldfaced symbols. If traditional \LaTeX~is used, one can use the |\mathbf| command instead.
+
+
+% \DescribeMacro\smeclearsym
+
+% Clear the style configuration associated with all symbols.
+
+
+% \subsection{Inline Math}
+
+% \makeatletter
+% In traditional \LaTeX, inline math is typeset with |$...$|. In \thispkg, we use |@...@| instead. For inline math demonstrations, see Examples \ref{ex:inl-1}, \ref{ex:inl-2}, \ref{ex:inl-3}, \ref{ex:inl-4}.
+
+% \DescribeMacro\makeatmath
+
+% The command changes the category code of |@| so that it can be used as the inline math environment. To revert the change, one can use |\makeatletter| or |\makeatother|.
+
+% \subsection{Display Math}
+
+% In order to use display math environments, we need to declare smart math environments using |\smenewenv|. The names of new math environments will be prefixed with ``sme''. The way of passing arguments to the math environment (e.g., \env{alignat}) will also be slightly different. For display math demonstrations, see Examples \ref{ex:disp-1}, \ref{ex:disp-2}, \ref{ex:disp-3}, \ref{ex:disp-4}, \ref{ex:disp-5}.
+
+% \DescribeMacro\smenewenv{<env name>}
+
+% Declares a ``smart'' math environment based on the traditional math environment provided in \meta{env name}. The name of the new math environment will be prefixed with ``sme''. For example, if one calls |\smenewenv{align}|, then the smart math environment \env{smealign} will be available.
+%\paragraph{Passing arguments} The arguments for math environments needed to be enclosed in square brackets. See Example \ref{ex:disp-5}.
+
+% \subsection{Raw Math Content}
+
+% \DescribeMacro\smeraw{<content>}
+% The \meta{content} of |\smeraw| will not be styled. This can be useful when one needs to style symbols manually in \thispkg~environments. See Examples \ref{ex:inl-4}, \ref{ex:disp-4}.
