+% \maketitle
+%
+% \begin{documentation}
+%
+% The \pkg{lt3luabridge} expl3~\cite{expl3} package provides support for
+% executing \Lua{} code in \Lua\TeX{} or any other \TeX{} engine that exposes
+% the shell. The package provides interfaces to plain \TeX, \LaTeX, and
+% \Hologo{ConTeXt}
+% formats:
+% \begin{verbatim}
+% \documentclass{standalone}
+% \usepackage{lt3luabridge}
+% \begin{document}
+% $ 1 + 2 = \luabridgeExecute{ print(1 + 2) } $
+% \end{document}
+% \end{verbatim}
+% The package was previously part of the Markdown package~\cite{markdown},
+% where it has been battle-tested since 2016. Since 2022, lt3luabridge has
+% also been available as a separate package.
+%
+% \section{Loading the package}
+%
+% Use the |\input lt3luabridge\relax| command to load the package from plain \TeX,
+% use the |\usepackage{lt3luabridge}| command to load the package from \LaTeX, and
+% use the |\usemodule[t][lt3luabridge]| command to load the package from \Hologo{ConTeXt}.
+%
+% \section{Executing \Lua{} code}
+%
+% The interface for executing \Lua{} code mimics the \cs{lua_now:n} function
+% from \pkg{l3luatex}.
+%
+% \begin{function}[added = 2022-06-26]{\luabridge_now:n, \luabridge_now:e}
+% \begin{syntax}
+% \cs{luabridge_now:n} \Arg{token list}
+% \end{syntax}
+% The \meta{token list} is first tokenized by \TeX{}, which includes
+% converting line ends to spaces in the usual \TeX{} manner and which
+% respects currently-applicable \TeX{} category codes. The resulting
+% \meta{\Lua{} input} is passed to the \Lua{} interpreter for processing.
+% Each \cs{luabridge_now:n} block is treated by \Lua{} as a separate chunk.
+% The \Lua{} interpreter executes the \meta{\Lua{} input} immediately,
+% and in an expandable manner.
+%
+% Unlike \cs{lua_now:n}, \cs{luabridge_now:n} may execute \meta{\Lua{} input}
+% in a separate process from \TeX. Therefore, you should not interact with
+% \TeX{} from \meta{\Lua{} input}. The only exception is the standard output
+% produced by \meta{\Lua{} input} using for example the |print()| \Lua{}
+% function like in the example at the top of this page. The standard output
+% will be inserted into \TeX's input stream after \meta{\Lua{} input} has
+% been processed at the latest.
+% \end{function}
+%
+% \begin{function}[added = 2022-06-26]{\luabridgeExecute}
+% \begin{syntax}
+% \cs{luabridgeExecute} \Arg{token list}
+% \end{syntax}
+% The \cs{luabridgeExecute} document command aliases
+% the \cs{luabridge_now:e} function.
+% \end{function}
+%
+% \section{Setting and getting the method to execute \Lua{} code}
+%
+% There are several methods that can be used to execute \Lua{} code. This
+% section describes the interface that the package provides to set the
+% preferred method or to determine which method was used.
+%
+% \begin{variable}[added = 2022-06-26]{\g_luabridge_method_int}
+% This variable controls the method used to execute \Lua{} code.
+% The variable is set automatically when the package is loaded
+% and changing the value of the variable afterwards has no effect.
+% However, we can set the value of the variable before loading the
+% package to one of the constants described below.
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\c_luabridge_method_write_eighteen_int}
+% Use shell escape through the \cs{write18} \TeX{} command to execute \Lua{} code.
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\c_luabridge_method_os_execute_int}
+% Use shell escape through the |os.execute()| Lua function to execute \Lua{} code.
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\c_luabridge_method_directlua_int}
+% Use the \cs{directlua} primitive of Lua\TeX{} to execute \Lua{} code.
+% \end{variable}
+%
+% \section{Setting and getting the filenames of helper files}
+%
+% When shell escape is used to execute \Lua{} code, several helper files are
+% needed to shuffle around code and output. The following variables and
+% constants are undefined when the \cs{directlua} primitive of Lua\TeX{} is
+% used to execute \Lua{} code.
+%
+% \begin{variable}[added = 2022-06-26]{\g_luabridge_output_dirname_str}
+% This variable controls the output directory that will store the helper
+% files. The variable should be set to the same value as the
+% \texttt{-output-directory} parameter of the \TeX{} engine.
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\c_luabridge_default_output_dirname_str}
+% This constant is the default value of \cs{g_luabridge_output_dirname_str}.
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\g_luabridge_helper_script_filename_str}
+% This variable controls the filename of a helper \Lua{} script that will be
+% executed from the shell using the \TeX{} \Lua{} interpreter.
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\c_luabridge_default_helper_script_filename_str}
+% This constant is the default value of
+% \cs{g_luabridge_helper_script_filename_str}.
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\g_luabridge_standard_output_filename_str}
+% This variable controls the filename of a helper file that will contain the
+% standard output produced by the |texlua| interpreter (if any).
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\c_luabridge_default_standard_output_filename_str}
+% This constant is the default value of
+% \cs{g_luabridge_standard_output_filename_str}.
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\g_luabridge_error_output_filename_str}
+% This variable controls the filename of a helper file that will contain the
+% error output produced by the |texlua| interpreter (if any).
+% \end{variable}
+%
+% \begin{variable}[added = 2022-06-26]{\c_luabridge_default_error_output_filename_str}
+% This constant is the default value of
+% \cs{g_luabridge_error_output_filename_str}.
+% \end{variable}
