A Lua script running LaTeX document files with TeX-style shebang
Description
In short, a TeX-style shebang (%#!) is a special kind of TeX
comment that you include in your TeX/LaTeX document file to
tell the operating system's shell how to run the file for the
rest of the file: %#!lualatex foo.tex \documentclass{article}
\begin{document} Hello, {\LaTeX} World! Happy {\TeX}ing.
\end{document} If you are using a TeX-style shebang, it must
appear on the line that matched 20 lines or less in your LaTeX
document, and it has to start with a TeX comment symbol (%)
followed by a hash sign (#) and an exclamation mark (!),
colloquially known as the bang, hence the name shebang for
TeX/LaTeX.
