The purpose of yathesis is to facilitate dissertations’ typesetting of theses prepared in France, whatever disciplines and institutes. It implements most notably recommendations from the Ministry of Higher Education and Research and this, transparently to the user. It has also been designed to (optionally) take advantage of powerful tools available in LaTeX, including packages: BibLaTeX for the bibliography; glossaries for the glossary, list of acronyms and symbols list. The yathesis class, based on the book class, aims to be both simple to use and, to some extent, (easily) customizable. yathesis comes with templates and samples in the doc/latex/yathesis/french/exemples/ directory in the distribution. They can also be tested on ShareLaTeX (template and specimen) and on Overleaf (template and specimen).
