-  \begin{description}
-  \item[Objectifs de la \gzt*{}.] Bulletin interne de la \smf{}, la \gzt{} est
-    un support privilégié d'expression au sein de la communauté
-    mathématique. À ce titre, elle informe de l'actualité des mathématiques, de
-    leur enseignement, de leur histoire, de leur relations avec d'autres
-    sciences (physique, informatique, biologie, etc.).
-
-    On y trouve donc des articles scientifiques de présentation, ainsi que des
-    récensions de parutions mathématiques récentes. Elle contient aussi des
-    informations sur tout ce qui concerne la vie professionnelle d'un
-    mathématicien (recrutements, conditions de travail, publications
-    scientifiques, etc.) et aussi des témoignages ou des tribunes libres.
-
-    La \gzt{} paraît à raison de quatre numéros par an avec, optionnellement, un
-    numéro spécial consacré à un sujet particulier de mathématiques ou bien à un
-    grand mathématicien.
-
-    Elle est envoyée gratuitement à chaque adhérent. Les numéros actuel et
-    anciens sont disponibles en ligne
-    (\url{http://smf4.emath.fr/Publications/Gazette/}).
-
-  \item[Soumission d'article.] Les articles doivent être envoyés au secrétariat,
-    de préférence par courrier électronique (\email{gazette@dma.ens.fr}), pour
-    être examinés par le comité de rédaction. Si un article est accepté, son
-    fichier source doit alors être fourni, de préférence sous forme d'un fichier
-    \TeX{} ou, à l'extrême rigueur, LibreOffice, OpenOffice ou
-    Word\textregistered{} ; une saisie de manuscrits est cependant possible pour
-    des textes courts.
-
-    Les fichiers \TeX{} doivent :
-    \begin{itemize}
-    \item de préférence recourir au format \LaTeXe{} : éviter les commandes des
-      autres formats (tels que plain \TeX{}) ;
-    \item être si possible \enquote{encodés} en \texttt{UTF-8} ;
-    \item être le plus \enquote{pur} possible : éviter les macros
-      \enquote{exotiques} ainsi que les insertions manuelles d'espacements
-      horizontaux ou verticaux (\gztverb{\hspace}, \gztverb{\hskip},
-      \gztverb{\vspace}, \gztverb{\vskip}, \gztverb{\enlargethispage}, etc.).
-    \end{itemize}
-    Les illustrations qui ne sont pas directement codées en \TeX{} doivent être
-    fournies aux formats \texttt{.pdf} (à privilégier) ou, avec un bonne
-    définition (300~\textsc{dpi} minimum), \texttt{.png} ou \texttt{.jpg}. Le
-    format \texttt{.eps}, quoique indirectement supporté, est déconseillé.
-
-    Pour faciliter la composition de textes destinés à la \gzt{}, la \smf{}
-    propose la classe \LaTeX{} \gztarticlecl{} fournie par les distributions
-    \TeX{} courantes (\TeX{} Live et Mac\TeX{} \aside{à partir de leur version
-      2015} ainsi que MiK\TeX{}), et sinon téléchargeable depuis la page
-    \url{http://ctan.org/pkg/gzt}.  Sa documentation détaillée se trouve à la
-    page \url{http://mirrors.ctan.org/macros/latex/contrib/gzt/doc/gzt.pdf}.  On
-    prendra garde au fait que l'usage de cette classe nécessite une distribution
-    \TeX{} à jour.
-
-    Pour plus de détails, consulter la page
-    \url{http://smf.emath.fr/content/la-gazette-des-mathematiciens}.
-    %
-    % \item[Rubrique \enquote{Mathématiques}] La \gzt{} publie des articles de
-    %   mathématiques et d'interactions ou applications des mathématiques,
-    %   chargés
-    %   de présenter un résultat, exposer une notion ou de commenter une
-    %   actualité.
-  %
-    %   Ils s'adressent à un public étendu. Les textes privilégiés sont courts,
-    %   pédagogiques et illustrés par des exemples.
-  %
-    %   La bibliographie ne vise pas à l'exhaustivité et se concentre sur les
-    %   textes
-    %   introductifs et de référence.
-  %
-    %   Les articles d'histoire des mathématiques ou contenant des vues
-    %   historiques
-    %   ou épistémologiques sont également bienvenus et doivent être conçus dans
-    %   le
-    %   même esprit.
-  %
-    % \item[Rubrique \enquote{Livres}] La rubrique \enquote{Livres} publie des
-    %   recensions s'attachant à présenter des ouvrages de mathématiques et des
-    %   ouvrages sur les mathématiques (leur histoire, leur philosophie, et plus
-    %   généralement tout ce qui a trait aux mathématiques et aux
-    %   mathématiciens).
-  %
-    %   Quelques recommendations :
-    %   \begin{itemize}
-    %   \item Commencez la recension en donnant quelques informations sur le
-    %     livre
-    %     (titre, nom l'auteur, collection à laquelle il appartient, nom de
-    %     l'éditeur, ville de la maison d'édition, année de la publication,
-    %     nombre
-    %     de pages, \textsc{isbn} et prix en euros ou en dollars).
-    %   \item Précisez à quel public (de quel niveau) s'adresse le livre.
-    %   \item Vous êtes libre de dire ce que vous pensez (dans les limites de la
-    %     politesse et de la correction). Le comité de rédaction se réserve la
-    %     décision finale de publication après relecture de votre recension.
-    %   \item Les recensions doivent être brèves (une ou deux pages, trois au
-    %     maximum) et synthétiser l'apport original d'un ouvrage. Dans le cas
-    %     des
-    %     ouvrages de mathématiques, elles n'ont pas pour objectif de rendre
-    %     compte
-    %     d'une théorie et d'en donner un exposé ; la recension proprement dite
-    %     peut
-    %     toutefois être précédée, à titre d'introduction à l'analyse de
-    %     l'ouvrage,
-    %     d'un bref exposé panoramique et historique des idées générales du
-    %     domaine.
-    %   \item N'insérez pas de bibliographie.
-    %   \item Signez de vos nom et prénom et indiquez les noms de
-    %     l'établissement et
-    %     de la ville où vous exercez.
-    %   \end{itemize}
