    \section*{penlight -- Lua libraries for use in LuaLaTeX}
    v. 2021-09.19, Kale Ewasiuk, \url{kalekje@gmail.com}

    \subsection*{Default}

    \begin{verbatim}
        \usepackage{penlight}
    \end{verbatim}

     If no options are used when using this package,
     then all penlight packages are available under the lua variable \texttt{penlight}.
    Here is an example:

    \begin{verbatim}
        \begin{luacode*}
            texio.write_nl(penlight.pretty.write(penlight.List('hello')))
        \end{luacode*}
    \end{verbatim}

    The official documentation for the lua library can be found here:\\
  \mbox{\url{https://stevedonovan.github.io/Penlight/api/manual/01-introduction.md.html#}}

    \subsection*{Package Options}

    \noindent
    \begin{tabular}{lp{4.5in}}
    \texttt{pl} &   will make penlight packages are available under the global lua variable \texttt{pl} or \texttt{penlight}.\\\\
    \texttt{stringx} & will import additional string functions into the string meta table.\\
                    & this will be ran in pre-amble: \texttt{require('pl.stringx').import()}\\
                        & \hspace*{-4em}\url{https://stevedonovan.github.io/Penlight/api/libraries/pl.stringx.html}\\\\
    \texttt{format} & allows \% operator for Python-style string formating\\
            & this will be ran in pre-amble: \texttt{require('pl.text').format\_operator()}\\
                & \hspace*{-4em}\url{https://stevedonovan.github.io/Penlight/api/libraries/pl.text.html}\\\\
    \texttt{func} & allows placehold expressions eg. \texttt{\_1 + 1} to be used \\
                & this will be ran in pre-amble: \texttt{penlight.utils.import('pl.func')}\\
                & \hspace*{-4em}\url{https://stevedonovan.github.io/Penlight/api/libraries/pl.func.html}\\\\
    \end{tabular}
