## Overview

csfse is a small Tkinter desktop tool for producing French enrollment certificates. The user enters student details, triggers generation, and the program combines them with LaTeX header/footer templates, writes a matricule-named .tex file, invokes XeLaTeX, and opens the resulting PDF in Evince. The README gives only the product purpose; the source shows the workflow. The source contains an apparent undefined variable (`s`) where the assembled certificate text is expected, so successful generation is not assured.

Main entry points: [`cs.py`](https://github.com/ixeny/csfse/blob/master/cs.py) (Generate handler), [`head.tex`](https://github.com/ixeny/csfse/blob/master/head.tex) (LaTeX header), [`foot.tex`](https://github.com/ixeny/csfse/blob/master/foot.tex) (LaTeX footer)
