% TeXsurgery v 0.6.0
%
% This tex package is a companion to the `texsurgery` `python` project:
%
% https://framagit.org/pang/texsurgery
%
% This `LaTeX` library will make sure that
%
% `pdflatex document.tex`
%
% will work, with reasonable defaults, for a document that is intended to work with `texsurgery`, and also has other uses, always in tandem with the `texsurgery` `pypi` package.
%
% However, remember that `texsurgery` is a `python` project whose main focus is on __evaluating code inside a `jupyter` kernel__, and this is _only_ achieved by installing the `python` package and calling the `texsurgery` command
%
% `texsurgery -pdf document.tex`
%
% Both the texsurgery python package and the TexSurgery CTAN package are distributed under a BSD license.
