+`gzt' is a new SMF bundle of classes for the French journal "La gazette des
+math'ematiciens".
+
+Installation
+------------
+
+The classes are supplied in dtx format. If you want to unpack the dtx yourself,
+running 'xetex gzt.dtx' will extract the two classes gzt.cls and gztarticle.cls
+whereas 'pdflatex gzt.tex' will typeset the gztarticle.cls' documentation.
+
+Typesetting the documentation also requires a number of packages in addition to
+those needed to use the gzt class.  To compile the documentation without error,
+you will need, among others, my personal package denisbdoc.sty for documenting
+packages which can be found on CTAN.

+\section{Introduction}
+\label{sec-introduction}
+
+\begin{dbremark}{Documentation : travail en cours}{}
+  La présente documentation est un travail en cours. Nous remercions d'avance
+  les lecteurs qui ont des remarques à formuler ou qui trouveront des erreurs de
+  nous les signaler à l'adresse courriel figurant en fin de document.
+\end{dbremark}
+
+La \smf fournit la classe \LaTeX{} \gztauthor{} destinée aux auteurs souhaitant
+publier un article dans la
+\href{http://smf4.emath.fr/Publications/Gazette/}{\gzt*{}}. Cette classe a pour
+but :
+\begin{enumerate}
+\item de reproduire fidèlement la maquette de la \gzt{}, permettant ainsi aux
+  auteurs de pouvoir travailler la mise en page de leur document dans des
+  conditions (quasi-)réelles ;
+\item de fournir un certain nombre d'outils (commandes et environnements)
+  destinés à faciliter la composition de documents, notamment ceux contenant des
+  formules de mathématiques.
+\end{enumerate}
+
+\section{Avertissements préliminaires}
+\label{sec-avert-prel}
+
+\begin{dbwarning}{Codage d'entrée \protect\lstinline+UTF-8+ obligatoire}{}
+  La \gztauthorcl{} de la \gzt{} repose de façon cruciale sur un codage
+  d'entrée en |UTF-8| :
+  \begin{itemize}
+  \item elle charge le \Package{inputenc}\footnote{%
+      Il convient donc de \emph{ne pas} charger ce package : on se reportera
+      à la \vref{sec-canevas-de-fichier} pour un canevas de fichier source
+      destiné à la \gzt{} et notamment pour un préambule typique.%
+      %
+    } avec l'option \docAuxKey{utf8} ;
+  \item elle suppose que les fichiers sources \file{.tex} sont effectivement
+    codés en |UTF-8| : on veillera donc à ce que l'éditeur utilisé soit réglé
+    sur ce codage d'entrée.
+  \end{itemize}
+\end{dbwarning}
+
+\begin{dbwarning}{Format et compilation \hologo{pdfLaTeX}}{}
+  La composition des numéros de la \gzt*{} met en œuvre :
+  \begin{itemize}
+  \item le format \hologo{LaTeX}\footnote{Sous sa version \hologo{LaTeXe}, la
+      plus courante de nos jours.}. On évitera donc les commandes des autres
+    formats tels que \hologo{plainTeX} ;
+  \item le compilateur \hologo{pdfLaTeX}. En particulier, le compilateur
+    \hologo{LaTeX} n'étant pas utilisé :
+    \begin{enumerate}
+    \item les formats d'images acceptés sont \format{jpg}, \format{png} et
+      \format{pdf}\footnote{Le format recommandé est \format{pdf} car il est
+        vectoriel si bien que la qualité des images n'est pas dégradée en cas de
+        redimensionnement.}. Le \Format{eps}, quoique indirectement
+      supporté, est déconseillé ;
+    \item le code \program{PostScript}, notamment via \program{PSTricks}, n'est
+      pas directement pris en charge. Bien qu'il soit accepté, il est à éviter
+      dans la mesure du possible.
+    \end{enumerate}
+  \end{itemize}
+\end{dbwarning}
+
+\begin{dbremark}{Composition par défaut en bi-colonne}{}
+  Sauf cas particuliers, tous les articles de la \gzt{} sont composés en mode
+  bi-colonne.
+\end{dbremark}
+
+\section{Article standard}
+\label{sec-article-standard}
+
+Nous commençons par décrire les éléments caractéristiques d'un article standard.
+
+\subsection{Préparation du \enquote{titre} de l'article}
+\label{sec-prep-de-lart}
+
+Cette section liste les commandes, options et environnement permettant de
+\emph{préparer} le \enquote{titre} de l'article ainsi que son éventuelle partie
+finale.
+
+\subsubsection{Titre, sous-titre}
+\label{sec-titre}
+
+\begin{docCommand}[doc description=\mandatory]{title}{\oarg{option}\marg{titre}}
+  Cette commande définit le \meta{titre} de l'article. Celui-ci apparaît alors
+  en début d'article et aussi comme métadonnée \enquote{Titre} du fichier
+  \textsc{pdf} correspondant.
+\end{docCommand}
+
+\begin{docCommand}{subtitle}{\oarg{option}\marg{sous-titre}}
+  Cette commande définit l'éventuel \meta{sous-titre} de l'article. Celui-ci
+  est automatiquement ajouté au titre.
+\end{docCommand}
+
+Les commandes \refCom{title} et \refCom{subtitle} admettent un argument
+optionnel permettant de spécifier comme \oarg{option} un (sous-)titre court au
+moyen de la clé \refKey{short}.
+
+\begin{docKey}{short}{=\meta{(sous-)titre court}}{pas de valeur par défaut,
+    initialement vide}
+  Cette clé définit un (sous-)titre \enquote{court} de l'article qui figure
+  alors à la place du (sous-)titre \enquote{normal} dans le sommaire et en titre
+  courant\footnote{En entête.}.
+\end{docKey}
+
+\begin{bodycode}
+\title[short=Les travaux de Martin \surname{Hairer}]{Martin \surname{Hairer},
+  l'équation de KPZ et les structures de régularité}
+\end{bodycode}
+
+\begin{dbremark}{Affichage des titre et sous-titre}{}
+  Pour que les titre et sous-titre soient affichés, il est nécessaire de
+  recourir à la commande habituelle \refCom{maketitle}.
+\end{dbremark}
+
+\subsubsection{Auteur(s)}
+\label{sec-auteurs}
+
+Un auteur d'article est spécifié au moyen de la commande \refCom{author}
+suivante. En cas d'auteurs multiples, il  suffit de recourir à plusieurs
+occurrences de cette commande.
+
+\begin{docCommand}{author}{\oarg{options}\brackets{\meta{Nom}, \meta{Prénom}}}
+  Cette commande, facultative, définit un auteur d'article.
+\end{docCommand}
+%
+\begin{dbwarning}{Format des prénom et nom de l'auteur}{}
+  On veillera à ce que :
+  \begin{enumerate}
+  \item la saisie des prénom et nom de l'auteur soit conforme à la syntaxe
+    (identique à celle de \hologo{BibTeX} et \package{biblatex}) :
+    %
+\begin{bodycode}[listing options={showspaces}]
+"\meta{Nom}", "\meta{Prénom}"
+\end{bodycode}
+    %
+  \item les éventuels accents figurent dans les \meta{Prénom} et
+    \meta{Nom} ;
+  \item le \meta{Nom} \emph{ne} soit \emph{pas} saisi en capitales
+    (sauf pour la ou les majuscules) car il sera automatiquement
+    composé en petites capitales.
+  \end{enumerate}
+\end{dbwarning}
+
+\begin{dbremark}{Affichage des prénoms et noms du ou des auteurs}{}
+  Pour que les prénoms et noms du ou des auteurs soient affichés, il est
+  nécessaire de recourir à la commande habituelle \refCom{maketitle}.
+\end{dbremark}
+
+\subsubsection{Auteur(s) : détails}
+\label{sec-auteurs-details}
+
+La commande \refCom{author} admet un argument optionnel permettant, pour chaque
+auteur, de spécifier un certain nombre de détails complémentaires : son affiliation, sa
+photo, son email, sa page Web, sa biographie express au moyen des clés
+respectives %^^A (à séparer par des virgules)
+\refKey{affiliation}, \refKey{photo}, \refKey{email}, \refKey{webpage} et
+\refKey{minibio} :
+\begin{bodycode}
+\author[%
+  affiliation="\marg{affiliation(s)}",%
+  photo="\meta{photo}",%
+  email="\meta{email}",%
+  webpage="\meta{page Web}",%
+  minibio="\marg{biographie express}"%
+]{"\meta{Nom}", "\meta{Prénom}"}
+\end{bodycode}
+
+\begin{docKey}{affiliation}{={\marg{affiliation(s)}}}{pas de valeur par défaut,
+    initialement vide}
+  Cette clé permet de spécifier une ou plusieurs affiliations. En cas
+  d'affiliations multiples, celles-ci peuvent être séparées par la commande
+  \docAuxCommand*{newline}.
+\end{docKey}
+
+\begin{docKey}{photo}{={\meta{photo}}}{pas de valeur par défaut,
+    initialement vide}
+  Cette clé permet de spécifier la photographie de l'auteur au moyen d'un
+  fichier image\footnote{Si ce fichier ne figure pas dans le dossier courant, il
+    faut faire figurer le chemin (relatif) y menant.}.
+\end{docKey}
+
+\begin{docKey}{email}{={\meta{email}}}{pas de valeur par défaut,
+    initialement vide}
+  Cette clé permet de spécifier l'adresse courriel de l'auteur.
+\end{docKey}
+
+\begin{docKey}{webpage}{={\meta{page Web}}}{pas de valeur par défaut,
+    initialement vide}
+  Cette clé permet de spécifier la page Web de l'auteur.

+\label{sec-outils-communs-tous}
+
+Cette section donne une liste exhaustive des outils (commandes et
+environnements) fournis par la \gztauthorcl.
+
+\subsection{Images et tableaux}
+\label{sec-images-tableaux}
+
+Les images et tableaux destinés à illustrer le corps d'un article doivent être
+insérés dans les environnements \refEnv{gztfigure}, \refEnv{gztfigure*},
+\refEnv{gzttable} et \refEnv{gzttable*}, analogues, décrits dans cette section.
+
+\subsubsection{Images}
+\label{sec-images}
+
+Une image est incluse au moyen de la commande standard
+\docAuxCommand{includegraphics}\footnote{Il est possible de passer à cette
+  commande toutes ses options définies par le \Package{graphicx}.} mais celle-ci
+doit être employée dans l'un des deux environnements \refEnv{gztfigure} et
+\refEnv{gztfigure*} suivants.
+
+\begin{docEnvironment}[doclang/environment content=image incluse avec \docAuxCommand{includegraphics}]{gztfigure}{\oarg{option(s)}}
+  Cet environnement insère l'image :
+  \begin{itemize}
+  \item \emph{à l'emplacement où il est utilisé} ;
+  \item dans un cadre de largeur la ligne courante, donc notamment de la largeur
+    de la ligne d'une colonne en mode bi-colonne.
+  \end{itemize}
+\end{docEnvironment}
+
+\begin{docEnvironment}[doclang/environment content=image incluse avec \docAuxCommand{includegraphics}]{gztfigure*}{\oarg{option(s)}}
+  Cet environnement insère l'image :
+  \begin{itemize}
+  \item en haut de la page où il a été employé, donc probablement \emph{pas}
+    à l'emplacement où il est utilisé (il s'agit d'une figure
+    \enquote{flottante}) ;
+  \item dans un cadre de largeur celle de l'empagement, donc à cheval sur les
+    deux colonnes en mode bi-colonne.
+  \end{itemize}
+\end{docEnvironment}
+
+\subsubsection{Tableaux}
+\label{sec-tableaux}
+
+Un tableau est créé au moyen de l'environnement standard
+\docAuxEnvironment{tabular}\footnote{Il est recommandé de faire usage du
+  \Package*{booktabs} pour produire des tableaux plus lisibles.} mais celui-ci
+doit être employé dans l'un des deux environnements \refEnv{gzttable} et
+\refEnv{gzttable*} suivants.
+
+\begin{docEnvironment}[doclang/environment content=tableau créé avec \docAuxEnvironment{tabular}]{gzttable}{\oarg{option(s)}}
+  Cet environnement insère le tableau :
+  \begin{itemize}
+  \item \emph{à l'emplacement où il est utilisé} ;
+  \item dans un cadre de largeur la ligne courante, donc notamment de la largeur
+    de la ligne d'une colonne en mode bi-colonne.
+  \end{itemize}
+\end{docEnvironment}
+
+\begin{docEnvironment}[doclang/environment content=tableau créé avec \docAuxEnvironment{tabular}]{gzttable*}{\oarg{option(s)}}
+  Cet environnement insère le tableau :
+  \begin{itemize}
+  \item en haut de la page où il a été employé, donc probablement \emph{pas}
+    à l'emplacement où il est utilisé (il s'agit d'un tableau
+    \enquote{flottant}) ;
+  \item dans un cadre de largeur celle de l'empagement, donc à cheval sur les
+    deux colonnes en mode bi-colonne.
+  \end{itemize}
+\end{docEnvironment}
+
+\subsubsection{Options}
+\label{sec-options-gzt}
+
+Les environnements \refEnv{gztfigure}, \refEnv{gztfigure*}, \refEnv{gzttable} et
+\refEnv{gzttable*} admettent en argument optionnel :
+\begin{itemize}
+\item la plupart des (très nombreuses) options de l'environnement
+  \docAuxEnvironment{tcolorbox} du \Package*{tcolorbox}. On retiendra notamment
+  les options suivantes :
+\begin{docKey}{title}{=\meta{titre}}{pas de valeur par défaut,
+    initialement vide}
+  Cette clé permet de spécifier l'éventuel \meta{titre} (ou légende).
+\end{docKey}
+\begin{docKey}{label}{=\meta{label}}{pas de valeur par défaut, initialement
+    vide}
+  Cette clé permet de spécifier l'éventuel \meta{label} de l'image, de sorte
+  à y faire référence, notamment au moyen de la commande \refCom{vref}.
+\end{docKey}
+\item la clé \refKey{copyright} suivante :\begin{docKey}{copyright}{=\meta{titulaire}}{pas de valeur par défaut, initialement
+    vide}
+  Cette clé permet de spécifier un éventuel \meta{titulaire} de
+  \emph{copyright}.
+\end{docKey}
+\end{itemize}
+
+Les exemples suivants illustrent les environnements et options qui viennent
+d'être vus.

+\end{gzttable*}
+\end{bodycode}
+
+\subsection{Bibliographie}
+\label{sec-bibliographie}
+
+Pour composer les bibliographies, la \gzt{} recourt aux outils modernes que sont
+le \Package*{biblatex} et le moteur \hologo{biber}. Leur usage est détaillé dans
+\autocite{Bitouze} et peut être brièvement résumé comme suit.
+\begin{enumerate}
+\item Construire, dans un \meta{fichier bibliographique}\footnote{De tels
+    fichiers sont d'extension \file{.bib}.}, une base bibliographique.
+
+  Nous conseillons pour ce faire de recourir à un logiciel dédié, par exemple
+  \href{http://jabref.sourceforge.net/}{\program{JabRef}} à configurer en se
+  rendant dans le menu \menu{Options>Preferences} et, dans l'onglet :
+  \begin{itemize}
+  \item \menu{Général}\footnote{On pourra en profiter pour changer la langue de
+      l'interface dans la liste déroulante \menu{Language}.}, en choisissant
+    \menu{UTF8} dans la liste déroulante \menu{Default encoding} ;
+  \item \menu{Advanced}, en cochant l'option \menu{BibLaTeX mode} ;
+  \end{itemize}
+
+  On n'oubliera pas de donner à chaque entrée bibliographique une \meta{clé}
+  permettant de l'identifier de façon unique dans la base
+  bibliographique\footnote{Sous \program{JabRef}, on pourra se faire aider pour
+    cela par l'icône en forme de \enquote{baguette magique}.}.
+\item Dans le fichier source \file{.tex} :
+  \begin{enumerate}
+  \item \emph{En préambule}, utiliser la commande \docAuxCommand{addbibresource}
+    pour indiquer le \meta{fichier bibliographique} à considérer :
+\begin{preamblecode}
+\addbibresource{"\meta{fichier bibliographique}".bib}
+\end{preamblecode}
+  \item Dans le corps du document, utiliser la commande
+    \docAuxCommand{autocite}\footnote{De préférence à la commande
+      \docAuxCommand{cite}.} du \Package*{biblatex} pour citer les références
+    bibliographiques (pourvue d'une \meta{clé}) :
+\begin{bodycode}
+\autocite{"\meta{clé}"}
+\end{bodycode}
+  \item À la fin du document, faire figurer la liste des références
+    bibliographiques au moyen de la commande \refCom{printbibliography}
+    suivante.
+  \end{enumerate}
+\item Procéder à une suite de compilations \hologo{pdfLaTeX}, \hologo{biber} et
+  \hologo{pdfLaTeX}\footnote{Pour automatiser ces compilations, on pourra
+    recourir au \enquote{compilateur} \program{latexmk}, fourni par toute
+    distribution \TeX{} moderne, en s'aidant du fichier de configuration
+    \file{latexmkrc} joint à la présente classe.}.
+\end{enumerate}
+
+\begin{docCommand}{printbibliography}{}
+  Cette commande produit la liste des références bibliographiques saisies selon
+  la syntaxe du \Package*{biblatex}. Elle a été redéfinie de sorte
+  à automatiquement afficher, en sus de la bibliographie, les détails
+  complémentaires sur les auteurs (s'ils ont été renseignés).
+\end{docCommand}
+
+\subsection{Commandes diverses}
+\label{sec-commandes-diverses}
+
+La \gztauthorcl{} fournit des commandes généralistes ou propres aux
+mathématiques destinées à faciliter la saisie d'un article à paraître dans la
+\gzt{}.
+
+\subsubsection{Commandes généralistes}
+\label{sec-comm-gener}
+
+\begin{docCommand}{smf}{}
+  Cette commande produit l'acronyme \textsc{smf} de la Société Mathématique de
+  France.
+\end{docCommand}
+
+\begin{docCommand}{gzt}{}
+  Cette commande :
+  \begin{description}
+  \item[sous sa forme non étoilée :] produit l'abréviation \enquote{\gzt}.
+  \item[sous sa forme étoilée :] produit la forme complète \enquote{\gzt*}.
+  \end{description}
+\end{docCommand}
+
+\begin{docCommand}{cad}{}
+  Cette commande :
+  \begin{description}
+  \item[sous sa forme non étoilée :] produit l'abréviation \enquote{c.-à-d.}.
+  \item[sous sa forme étoilée :] produit la forme complète
+    \enquote{c'est-à-dire}.
+  \end{description}
+\end{docCommand}
+
+\begin{docCommand}{Cad}{}
+  Cette commande :
+  \begin{description}
+  \item[sous sa forme non étoilée :] produit l'abréviation \enquote{C.-à-d.}.
+  \item[sous sa forme étoilée :] produit la forme complète
+    \enquote{C'est-à-dire}.
+  \end{description}
+\end{docCommand}
+
+\begin{docCommand}{surname}{\marg{nom de famille}}
+  Cette commande compose le \meta{nom de famille} en petites capitales.
+  \begin{dbwarning}{Petites capitales : à employer avec parcimonie}{}
+    \begin{itemize}
+    \item De manière générale, quand elles sont appliquées aux noms de
+      personnes, les petites capitales doivent ne s'appliquer qu'au nom de
+      famille, et notamment \emph{pas} aux prénoms.
+    \item Pour un article de la \gzt{}, on évitera d'appliquer systématiquement
+      les petites capitales (et donc la commande \refCom{surname}) à tous les
+      noms de famille : on les réservera aux noms d'auteurs, notamment à ceux
+      spécialement mis à l'honneur, par exemple s'ils figurent dans le titre
+      d'un article.
+    \end{itemize}
+  \end{dbwarning}
+\end{docCommand}
+
+\begin{docCommand}{century}{\marg{numéro}}
+  Cette commande affiche le \meta{numéro}\footnote{Ce numéro doit être un nombre
+    entier relatif non nul.} d'un siècle en chiffre romain composé en petites
+  capitales, suivi :
+  \begin{itemize}
+  \item du mot \enquote{siècle} ou \enquote{century} ;
+  \item si \meta{numéro} $<0$, de l'expression \enquote{avant J.-C.} ou
+    \enquote{BC} ;
+  \end{itemize}
+  selon que la langue en cours est le français ou l'anglais.  Ainsi :
+\begin{bodycode}[listing and text]
+Au \century{1}, [...]. Plus tard, au \century{8}, [...]
+\end{bodycode}
+\end{docCommand}
+
+\begin{docCommand}{aside}{\marg{texte}}
+  Cette commande permet de composer du \meta{texte} entre tirets longs, pour une
+  \enquote{incise} (un peu à la manière de parenthèses).
+  \begin{description}
+  \item[Sous sa forme non étoilée,] elle insère le \meta{texte} entre deux
+    tirets longs.
+  \item[Sous sa forme étoilée,] elle fait (seulement) précéder le \meta{texte}
+    d'un tiret, ce qui est à utiliser en fin de phrase.
+  \end{description}
+  Ainsi :
+\begin{bodycode}[listing and text]
+Des expériences \aside{dans le monde \enquote{réel}} ont même été suscitées
+par des expériences numériques.
+\end{bodycode}
+  et :
+\begin{bodycode}[listing and text]
+On soupçonne que non \aside*{par exemple on s'attend à ce que $1/\pi$ ne
+soit pas une période}.

+\subsubsection{Commandes propres aux mathématiques}
+\label{sec-comm-propr-aux}
+
+La \gztauthorcl{} :
+\begin{itemize}
+\item charge les packages :
+  \begin{itemize}
+  \item \package*{kpfonts} qui fournit tous les symboles standard, y compris
+    ceux du \Package{amssymb}, mais en propose également de nombreux autres ;
+  \item \package*{mathtools} qui lui-même charge \package*{amsmath} (mais en
+    l'étendant et en corrigeant certains de ses défauts), si bien que toutes les
+    commandes de ces deux packages sont disponibles ;
+  \item \package*{mathrsfs} qui fournit de jolies lettres calligraphiques (via
+    la commande \docAuxCommand{mathscr}) ;
+  \end{itemize}
+\item redéfinit certaines commandes et en fournit quelques nouvelles, listées
+  ci-dessous ;
+\item fournit (en s'appuyant sur les packages \package*{amsthm} et

+\subsubsection{Code informatique}
+\label{sec-commande-pour-code}
+
+La \gztauthorcl{} fournit des outils permettant de faire aisément figurer du
+code informatique, notamment du code \LaTeX{} :
+\begin{itemize}
+\item l'environnement \refEnv{gztcode} pour des listings ;
+\item la commande \refCom{gztverb} pour de courts extraits, notamment amenés
+  à figurer dans des phrases.
+\end{itemize}
+
+\begin{docEnvironment}[doclang/environment content=listing]{gztcode}{\oarg{option(s)}}
+  Cet environnement permet de faire figurer un listing de code informatique dans
+  une boîte colorée.
+\begin{bodycode}[listing and text]
+Nous préconisons l'environnement \verb|align*| :
+\begin{gztcode}
+\begin{align*}
+  a & = a\\
+  b & = b
+\end{align*}
+\end{gztcode}
+\end{bodycode}
+\end{docEnvironment}
+
+L'environnement \refEnv{gztcode} admet en argument optionnel la plupart des
+(très nombreuses) options de l'environnement \docAuxEnvironment{tcblisting} du
+\Package*{tcolorbox}. On retiendra notamment les options suivantes.
+
+\begin{docKey}{title}{=\meta{titre}}{pas de valeur par défaut,
+    initialement vide}
+  Cette clé permet de donner un \meta{titre} au listing.
+\begin{bodycode}[listing and text,listing options={morekeywords={[2]title}}]
+Nous préconisons l'environnement \verb|align*| :
+\begin{gztcode}[title=Alignement d'équations]
+\begin{align*}
+  a & = a\\
+  b & = b
+\end{align*}
+\end{gztcode}
+\end{bodycode}
+\end{docKey}
+
+\begin{docKey}{listing and text}{}{}
+  Cette clé permet de, dans la boîte colorée, faire figurer en partie :
+  \begin{itemize}
+  \item haute, le listing ;
+  \item basse, son résultat compilé par \LaTeX{}.
+  \end{itemize}
+  % ^^A
+  \begin{dbwarning}{Option \protect\refKey*{listing and text} : seulement pour

+    \LaTeX{}.
+  \end{dbwarning}
+\begin{tcboutputlisting}
+\begin{gztcode}[listing and text]
+L'environnement \verb|eqnarray| est obsolète et nous préconisons plutôt

+code :
+\tcbinputlisting{codes,listing only}
+donne :
+\input{\jobname.listing}
+\end{docKey}
+
+L'environnement \refEnv{gztcode} permet d'afficher du code informatique
+arbitraire.  Mais, dans les listings précédents, on constate que certaines
+commandes \LaTeX{} sont mises en évidence, en l'occurrence en gras. Ceci
+provient du fait que l'environnement \refEnv{gztcode} est configuré pour, par
+défaut, colorer syntaxiquement le code \LaTeX{}. Mais d'autres langages sont
+pris en charge.
+
+\begin{dbremark}{Environnement \protect\refEnv*{gztcode} : pas seulement pour le
+    code \LaTeX{}}{}
+  L'environnement \refEnv{gztcode} permet de colorer syntaxiquement le code
+  informatique de tout langage connu du \Package*{listings}. Pour ce faire, il
+  suffit de le spécifier (selon la syntaxe de ce package) en argument de
+  l'option \refKey{listing options} suivante.
+\end{dbremark}
+
+\begin{docKey}{listing options}{}{}
+  Cette clé de l'environnement \refEnv{gztcode} permet de passer au listing

+  argument.
+
+  L'exemple suivant illustre l'usage de cette commande\conseilslatex.

+Dans le cas de \LaTeX, les commandes de style de caractères \gztverb{\bf},
+\gztverb{\it}, \gztverb{\sf}, \gztverb{\tt}, \gztverb{\sc}, \gztverb{\sl},
+\gztverb{\rm} sont désormais à proscrire. Elles doivent être remplacées par

+\subsection{Guillemets, citations}
+\label{sec-guillemets-citations}
+
+Le \Package*{csquotes} est dédié aux citations, formelles et informelles,
+d'extraits de textes. Il propose notamment la commande \refCom{enquote}
+suivante, simple d'emploi.
+
+\begin{docCommand}{enquote}{\marg{texte}}
+  Cette commande compose le \meta{texte} entre guillemets, automatiquement
+  adaptés :
+  \begin{itemize}
+  \item aux standards typographiques de la langue en cours. On pourra donc
+    l'utiliser dès que du texte est à mettre entre guillemets ;
+  \item au niveau (1 ou 2) de \enquote{citation} en cas d'emboîtement. On
+    pourra donc également l'utiliser dès que du texte est à citer de façon
+    informelle.

+\begin{docCommand}{textelp}{\marg{texte}}
+  Cette commande est à employer pour signifier une omission, avec éventuel ajout
+  de \meta{texte}.

+
+\subsection{Adresses Web (\enquote{\textsc{url}})}
+\label{sec-url}
+
+Le \Package*{hyperref} fournit (entre autres) la commande \refCom{url} qui permet
+de facilement afficher des adresses Web (aussi appelées \enquote{\textsc{url}}),
+même si elles comportent des caractères spéciaux de \TeX{} (|#|, |_|, |~|,
+\lstinline[commentstyle={}]+%+, |&|, etc.).
+
+\begin{docCommand}{url}{\marg{adresse Web}}
+  Cette commande affiche l'\meta{adresse Web} saisie \emph{telle
+    quelle}\footnote{Notamment sans faire précéder les éventuels caractères
+    spéciaux qu'elle contient de la commande d'échappement
+    \protect\lstinline+\\+.} et fait d'elle un lien hypertexte.

+
+\subsection{Références croisées}
+\label{sec-references-croisees}
+
+Le \Package*{cleveref}, utilisé conjointement avec le \Package*{varioref}, rend la
+commande \refCom{vref} de ce dernier très puissante.
+
+\begin{docCommand}{vref}{\marg{label}}
+  Cette commande affiche le numéro de la référence labellisée par \meta{label}
+  et :
+  \begin{itemize}
+  \item affiche (ou pas selon le contexte) la page où se situe cette
+    référence\footnote{Fonctionnalité fournie par le \Package{varioref}.} ;
+  \item détecte automatiquement la nature de la référence (section, tableau,
+    figure, équation, théorème, etc.) et fait précéder le numéro de celle-ci du
+    mot clé correspondant\footnote{Fonctionnalité fournie par le

+\section{Notations, syntaxe, terminologie et codes couleurs}\label{sec-synt-term-notat}
+
+Cette section précise les notations, syntaxe, terminologie et codes couleurs de
+la présente documentation.
+
+
+\subsection{Commandes, environnements, clés, valeurs}\label{sec-comm-envir-cles}
+
+Les commandes, environnements, clés et valeurs de clés sont systématiquement
+composés en fonte à chasse fixe. En outre, pour plus facilement les
+distinguer, ils figurent avec des couleurs propres :
+\begin{itemize}
+\item les commandes en bleu : \docAuxCommand*{commande} ;
+\item les environnements en \enquote{sarcelle} :
+  \docAuxEnvironment*{environnement} ;
+\item les clés en pourpre : \docAuxKey*{clé} ;
+\item les valeurs des clés en violet : \docValue*{valeur}.
+\end{itemize}
+
+\subsection{Arguments génériques}
+\label{sec-arguments-generiques}
+
+Pour expliquer le rôle d'une commande, il est parfois nécessaire d'indiquer
+à quoi celle-ci s'applique, autrement dit quel en est l'argument générique.
+Un tel argument est composé :
+\begin{itemize}
+\item en fonte à chasse fixe ;
+\item en italique ;
+\item entre chevrons simples ;
+\end{itemize}
+le tout en marron, ainsi : \meta{argument générique}.
+
+\subsection{Liens hypertextes}
+\label{sec-liens-hypertextes}
+
+Les liens hypertextes figurent en couleur, ainsi :
+\href{http://gte.univ-littoral.fr/members/dbitouze/pub/latex}{lien hypertexte}.
+La plupart des références aux commandes, environnements et clés définis dans la
+présente documentation, sont des liens hypertextes, surmontés du numéro de page
+où se trouve la cible correspondante (sauf si elle se situe sur la même page) :
+\begin{itemize}
+\item \refCom{author} ;
+\item \refEnv{abstract}.
+\end{itemize}
+
+
+\subsection{Éléments \enquote{obligatoires}}
+\label{sec-comm-oblig}
+
+L'icône \mandatory{}, figurant en regard de certains éléments (commandes ou
+environnements), indique que ceux-ci sont \enquote{obligatoires}.
+
+\subsection{Codes sources}
+\label{sec-codes-sources}
+
+Les exemples qui illustrent la présente documentation sont constitués de codes
+sources et, le cas échéant, des \enquote{copies d'écran} correspondantes.
+
+Ces codes sources figurent dans des cadres de couleur bleu :
+\begin{itemize}
+\item non ombrés s'ils doivent être saisis dans le corps du document ;
+\item ombrés s'ils doivent être saisis en préambule du fichier (maître).
+\end{itemize}
+Ces cadres pourront en outre comporter d'éventuels titres :
+\begin{multicols}{2}
+\begin{bodycode}
+"\meta{code source}"
+\end{bodycode}
+\begin{bodycode}[title=\meta{titre}]
+"\meta{code source}"
+\end{bodycode}
+\begin{preamblecode}
+"\meta{code source à insérer en préambule}"
+\end{preamblecode}
+\begin{preamblecode}[title=\meta{titre}]
+"\meta{code source à insérer en préambule}"
+\end{preamblecode}
+\end{multicols}
+
+\subsection{Espaces dans les codes sources}
+\label{sec-espaces-dans-les}
+
+Pour éviter certaines confusions, les espaces dans les codes sources devant
+être saisis au clavier sont parfois matérialisés au moyen de la marque
+\lstinline[showspaces]+ +.
+
+\subsection{Options}
+\label{sec-options}
+
+La présente classe, ainsi que certaines de ses commandes et certains de ses
+environnements, peuvent être modulés au moyen d'options, ou listes d'options
+(séparées par des virgules). Ces options se présentent sous la forme
+\meta{clé}|=|\meta{valeur} et la \meta{valeur} passée à une \meta{clé} peut
+être :
+%^^A \begin{description}
+%^^A \item[ne prennent pas de valeur.] Une telle option, par exemple nommée
+%^^A   \refKey{option}, est alors documentée selon la syntaxe suivante:
+%^^A     \begin{docKey*}{option}{}{\meta{valeurs par défaut et initiale}}
+%^^A       \meta{Description de \refKey{option}}
+%^^A     \end{docKey*}
+%^^A \item[prennent des valeurs.] Une telle option se présente alors sous la forme
+%^^A   \meta{clé}"="\meta{valeur}. Les valeurs passées à une clé peuvent être :
+\begin{description}
+\item[libre.] Si une telle \meta{clé} est (pour l'exemple) nommée
+  \refKey{freekey}, elle est alors documentée selon la syntaxe suivante :
+  \begin{docKey*}{freekey}{=\meta{valeur}}{\meta{valeurs par défaut et initiale}}
+    \meta{Description de \refKey{freekey}}
+  \end{docKey*}
+\item[imposée] (parmi une liste de valeurs possibles). Si une telle \meta{clé} est
+   (pour l'exemple) nommée \refKey{choicekey} et de valeurs imposées
+  \docValue*{valeur1}, \docValue*{valeur2}, ..., \docValue*{valeurN}, elle est alors
+  documentée selon la syntaxe suivante\footnote{Comme souvent en informatique,
+    la barre verticale séparant les valeurs possibles signifie \enquote{ou}.} :
+  \begin{docKey*}{choicekey}{=\docValue*{valeur1}\textbar\docValue*{valeur2}\textbar...\textbar\docValue*{valeurN}}{\meta{valeurs par défaut et initiale}}
+    \meta{Description de \refKey{choicekey} et de ses valeurs possibles}
+  \end{docKey*}
+\end{description}
+%^^A \end{description}
+
+Les \meta{valeurs par défaut et initiale} d'une clé sont souvent précisées
+(entre parenthèses en fin de ligne). Elles indiquent ce que la clé vaut :
+\begin{description}
+\item[par défaut] c'est-à-dire lorsque la clé \emph{est} employée, mais
+  \emph{seule} c'est-à-dire sans qu'une valeur explicite lui soit passée ;
+\item[initialement] c'est-à-dire lorsque la clé \emph{n'est pas} employée.

+\section{Packages chargés par la classe}\label{sec-packages-charges-par}

+
+`gzt' is a new SMF bundle of classes for the French journal "La gazette des
+math'ematiciens".
+
+Installation
+------------
+
+The classes are supplied in dtx format. If you want to unpack the dtx yourself,
+running 'xetex gzt.dtx' will extract the two classes gzt.cls and gztarticle.cls
+whereas 'pdflatex gzt.tex' will typeset the gztarticle.cls' documentation.
+
+Typesetting the documentation also requires a number of packages in addition to
+those needed to use the gzt class.  To compile the documentation without error,
+you will need, among others, my personal package denisbdoc.sty for documenting
+packages which can be found on CTAN.

+%
+% \subsection{For the interviews}
+%
+% First, we create the new entry type "interview" and the new field

+% and its layout) and one of packages useful for the end user.}
+%
+% \begin{enumerate}
+% \item Compile \TeX{} pictures stand-alone or as part of a document:

+% \item Extending \pkg{etoolbox}'s patching commands:

+%
+% \item Tools to load and manipulate data:
+%    \begin{macrocode}
+\RequirePackage{datatool}%
+%    \end{macrocode}
+%

+% \begin{macro}{\president}
+% \begin{macro}{\classdesigner}
+% \begin{macro}{\fontdesigner}
+% \begin{macro}{\classmaintainer}
+% \begin{macro}{\graphicdesigner}
+%   We define some document-level commands that let the user specify
+%   respectively the editor(s) in chief, the editors, the (\textsc{smf})
+%   president, the class designer and maintainer(s), and the graphic designer.
+%
+%   For the editor(s) in chief, we increment the "\g_@@_editors_in_chief_int"

+%   \enquote{Rédacteur(s) en chef}.

+% \end{macro}
+% \end{macro}
+% \end{macro}
+% \end{macro}
+%
+% \subsection{Issue setup}
+%
+% \begin{macro}{\issuesetup}
+%   We define the command that lets the user specify the issue setup.
+%    \begin{macrocode}
+\NewDocumentCommand \issuesetup { m } {
+%    \end{macrocode}
+%
+% Its keys are set (only "number", "month" and "year" are relevant here).
+%    \begin{macrocode}
+  \keys_set:nn { gzt/issuesetup } { #1 }
+%    \end{macrocode}
+%
+% We fix some of the PDF's metadata .
+%    \begin{macrocode}
+\hypersetup{pdftitle=\l_@@_pdftitle_string_tl}
+\hypersetup{pdfauthor=\l_@@_pdfauthor_string_tl}
+%    \end{macrocode}
+%
+% We use here the fact that, if the "number", "month" or "year" options are not
+% used, their corresponding "\g_@@_issue_number_int", "\g_@@_issue_month_int" or
+% "\g_@@_issue_year_int" variables are equal to $0$ ($<1$).
+%
+% First, if "number" is not used, its "\g_@@_issue_number_int" variable is set
+% to "\c_@@_first_issue_number_int"\footnote{The number of the first Gazette's
+% issue using the present class.} and a warning is emitted.
+%    \begin{macrocode}
+  \int_compare:nNnT {\g_@@_issue_number_int}<{1}
+  {
+    \int_set:Nn \g_@@_issue_number_int { \c_@@_first_issue_number_int }
+    \msg_warning:nnn{gzt}{issue-number-needed}{number}
+  }
+%    \end{macrocode}
+%
+% If not specified as \refCom{issuesetup}'s key-value options, issue's month and
+% year are computed from issue number (which defaults to
+% "\c_@@_first_issue_month_int").
+%
+% \begin{macro}{\c_@@_issue_age_in_months_int}
+%   First, if "month" or "year" option is not used (one of the previous
+%   variables is $0$ hence their product is $0$ ($<1$)), we compute the issue
+%   age in months, useful for both month and year computation.
+%    \begin{macrocode}
+  \int_compare:nNnT {\g_@@_issue_month_int * \g_@@_issue_year_int}<{1}
+  {
+    \int_new:N \g_@@_issue_age_in_months_int%

+      * ( \int_use:N \g_@@_issue_number_int - \c_@@_first_issue_number_int )
+    }
+  }
+%    \end{macrocode}
+% \end{macro}
+%
+% If the "month" is not used, we replace "\g_@@_issue_month_int" ($=0$) by its
+% computed value from the issue number.
+%    \begin{macrocode}
+  \int_compare:nNnT {\g_@@_issue_month_int}<{1}
+  {
+    \int_gset:Nn \g_@@_issue_month_int
+    {
+      \int_mod:nn { \g_@@_issue_age_in_months_int } { 12 }
+    }
+  }
+%    \end{macrocode}
+%
+% If the "year" is not used, we replace "\g_@@_issue_year_int" ($=0$) by its
+% computed value from the issue number.
+%    \begin{macrocode}
+  \int_compare:nNnT {\g_@@_issue_year_int}<{1}
+  {
+    \int_new:N \g_@@_issue_age_in_years_int%

+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{Journal setup}
+%
+% \begin{macro}{\journalsetup}
+%   We define the command that lets the user specify the
+%   journal setup. This setup is likely to be rarely changed.
+%    \begin{macrocode}
+\NewDocumentCommand \journalsetup { m } {
+%    \end{macrocode}
+%
+% Its keys are set (only "publisher", "address", "phone", "fax", "email", "url"

+%    \begin{macrocode}

+}
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{Date of the president's message}
+%
+% \begin{macro}{\date}
+%   We redefine the "\date" for the date of the president's message. It takes
+%   3 arguments, each of them being a number: the day, the month and the year.
+%    \begin{macrocode}

+% \section{(Re)Definition of document commands that identify the article}
+%
+% The names of the authors of the different articles will appear at several
+% places, and notably in the table of contents where first and middle names have to
+% be rendered as initials. Because automatically rendering initials is a complex task
+% already provided by \Pkg{biblatex}, we will create a \file{.bib} file
+% containing "article" entries for each article of the \gzt{} journal.
+%
+% This can be done only at the beginning of the document, in order to know the
+% characteristics of the current issue.
+%    \begin{macrocode}
+\AtBeginDocument{%
+%    \end{macrocode}
+%
+% We first create a token list containing the date of the current issue formated
+% as required by \pkg{biblatex} (the month issue needs a leading zero if it is
+% $<10$).
+%    \begin{macrocode}
+\tl_new:N \g_@@_bib_issue_date_tl
+\tl_gset:Nn \g_@@_bib_issue_date_tl {
+  \int_use:N \g_@@_issue_year_int-

+  {
+    0
+  }
+  \int_use:N \g_@@_issue_month_int
+}
+%    \end{macrocode}
+%
+% We will populate the bibiliographic file of the current issue with the current
+% issue (as "@periodical" entry type).
+%    \begin{macrocode}
+  \iow_now:Nx \g_@@_bib_out_iow {%
+    @periodical{\c_@@_issue_bib_key_tl,\iow_newline:

+%    \end{macrocode}
+%
+% \begin{macro}{\title}

+%
+% \subsection{Usual theorems and the like}
+%
+% Some usual theorems and the like are defined, thanks to \Pkg{thmtools}. First,
+% we define a private function "\_@@_new_theorem" that defines:
+% \begin{enumerate}
+% \item a new (private, \pkg{thmtools}) theorem with 4 arguments:
+%   \begin{enumerate}
+%   \item possible additional options to the style "_@@_tcb_alltheorems_style"
+%     defined earlier for all \enquote{theorems},
+%   \item name of the (private) \pkg{thmtools} theorem,
+%   \item French title for this theorem,
+%   \item English title for this theorem.
+%   \end{enumerate}
+% \item a public environment based on this private theorem with a the usual
+%   syntax of \pkg{amsthm} theorems, except it has an optional argument for
+%   possible additional options to the default styles ("theorem" or
+%   "definition").
+% \end{enumerate}
+%
+% \begin{macro}{\bilingual}
+%    \begin{macrocode}
+\cs_new_protected:Nn \_@@_bilingual:nnn
+{
+  \deftranslation[to=French]{#1}{#2}%
+  \deftranslation[to=English]{#1}{#3}%
+}
+%    \end{macrocode}
+% \end{macro}
+%
+%    \begin{macrocode}
+\cs_new_protected:Nn \_@@_new_theorem:nnnn
+{
+  % \_@@_bilingual:nnn {#2}{#3}{#4}

+\declaretheoremstyle[spaceabove=3pt,bodyfont=\normalfont,qed=\ensuremath{\qedsymbol},headfont=\normalfont\itshape,numbered=no]{proof}
+%    \end{macrocode}
+%
+% Then, we define a public command, similar to "\newtheorem", based on
+% "\_@@_new_theorem", that lets the user define his own theorems:
+%    \begin{macrocode}
+\RenewDocumentCommand \newtheorem { O{} m }

+  \IfNoValueF {#1}

+}
+%    \end{macrocode}
+%
+% Finally, we define some usual theorems:
+%    \begin{macrocode}
+\newtheorem[frenchtitle=Th\'eor\`eme]{theorem}
+% \newtheorem[frenchtitle=Th\'eor\`eme,englishtitle=Theorem]{theoreme}
+\newtheorem[frenchtitle=Corollaire]{corollary}

+  \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}

+  \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}
