% Additional lua functions taken from the libs of Con\TeX t. For an
% introduction on this package (among others), please refer to the document
% \texttt{luatex-reference.pdf}.
% \end{abstract}
%
% \section{Overview}
%
% Lua is a very minimal language, and it does not have a lot of built-in
% functions. Some functions will certainly be needed by a lot of packages.
% Instead of making each of them implement these functions, the aim of this
% file is to provide a minimal set of functions. All functions are taken from
% Con\TeX t libraries.
%
% There are some differences with the Con\TeX t funtions though, especially on
% names: for example the \texttt{file.*} funtions are renamed in
% \texttt{fpath.*}. It seems more logical as they deal with file paths, not
% files. Also the \texttt{file.is\_readable} and \texttt{file.is\_writable}
% are renamed \texttt{lfs.is\_readable} and \texttt{lfs.is\_writable}.
%
% If you use a function you think is missing in this file, please tell the
% maintainer.
%
% \texttt{Warning:} Even if the names will certainly remain the same, some
% implementations may differ, and some functions might appear or dissapear. As
% Lua\TeX\ is not stable, this file is not neither.
%
% All functions are described in this document, but the one of the functions
% you'll use most will certainly be \texttt{table.serialize} (also named
% \texttt{table.tostring}) that takes a table and returns an intented string
% describing the table. It describes the table so that Lua\TeX\ can read it
% again as a table. You can do a lot of things with this functions, like
% printing a table for debugging, or saving a table into a file. Functions are
% also converted into bytecode to be saved.
