This bundle provides two classes and BibLaTeX styles for the French journal [“La Gazette des Mathématiciens”](https://smf.emath.fr/les-publications/la-gazette): - `gzt` for the complete issues of the journal, aimed at the Gazette’s team, - `gztarticle`, intended for authors who wish to publish an article in the Gazette. This class’s goals are to - faithfully reproduce the layout of the Gazette, thus enabling the authors to be able to work their document in actual conditions, and - provide a number of tools (commands and environments) to facilitate the drafting of documents, in particular those containing mathematical formulas.
