+%   \begin{abstract}
+%     \LaTeX\ produces small caps with
+%     \cs{textsc}\marg{text} or \cs{scshape}. Both of these
+%     commands don't produce small caps in Unicode. If the
+%     output text is copied and pasted somewhere it shows
+%     the same characters used in the input. This package
+%     aims to internally convert all the characters provided
+%     to the commands mentioned above. It assumes that the
+%     file using this package is compiled with Lua/\XeLaTeX\
+%     \& a good Unicode font which has the small caps
+%     characters, e.g.,
+%     \href{https://ctan.org/pkg/charissil}{Charis
+%     SIL}. Please note that as there are no Unicode slots
+%     allotted to upper case small caps, both the lower case
+%     and upper case input will be converted to only one
+%     relevant Unicode character in the output, e.g.,
+%     \verb|\textsc{Hh}| will produce the same character
+%     twice unlike \verb|\oldtextsc{Hh}|.

+%     \section{Documentation}
+%     
+%     This package provides the following two macros.
+%
+%     \subsection{Macros}
+%     
+%     This package renews two basic \LaTeX\ commands, i.e.,
+%     \cs{scshape} \& \cs{textsc}. To keep the original
+%     definitions available for the users, I have copied the
+%     old commands \& provided two of the following macros
+%     which behave exactly like their old variants.
+%     
+%     \begin{function}{\oldscshape}
+%       \begin{syntax}
+%         \{\cs{oldscshape} \meta{text}\}
+%       \end{syntax}
+%     \end{function}
+%
+%     \begin{function}{\oldtextsc}
+%       \begin{syntax}
+%         \cs{oldtextsc}\marg{text}
+%       \end{syntax}
+%     \end{function}
+%
+%     \subsection{The \enquote*{x} factor}
+%
+%     This package doesn't support the small capital shape
+%     of the character \enquote*{x} as there is no Unicode
+%     number allotted for a \enquote*{small capital x} as of
+%     now. The package simply prints the small x (for both
+%     \verb|\textsc{x}| \& \verb|\textsc{X}|) as it is of
+%     the same height of the other small capital letters
+%     along with a warning message that warns the users
+%     about this deviation.
+%     
+%     \subsection{Example}
+%     
+%     \begin{mdframed}
+% \begin{verbatim}
+% \documentclass{article}
+% \usepackage{unisc}
+% \usepackage{fontspec}
+% \setmainfont{CharisSIL}% https://ctan.org/pkg/charissil
+
+% \begin{document}
+% \noindent\textbf{Fake small caps:}
+% {\oldscshape hello world} \oldtextsc{hello world}.
+
+% \noindent\textbf{Unicode small caps:}
+% {\scshape hello world} \textsc{hello world}.
+% \end{document}
+% \end{verbatim}
+%     \end{mdframed}
+%     
+%     This produces the following:
+%     
+%     \begin{mdframed}
+%       \charissil
+%       \noindent\textbf{Fake small caps:}
+%       {\oldscshape hello world} \oldtextsc{hello world}.
+%       
+%       \noindent\textbf{Unicode small caps:}
+%       {\scshape hello world} \textsc{hello world}.
+%     \end{mdframed}
+%   \end{documentation}

+% As pointed out by Florent Rougon in
+% \href{https://topanswers.xyz/transcript?room=2050&id=138859#c138859}%
+% {this} comment; the definition of \cs{oldtextsc} uses
+% \cs{scshape} twice which needs to be replaced with
+% \cs{oldscshape}. For that the following patching is done
+% \& the old definition is retained.
+%    \begin{macrocode}
