+\section{Introduction}
+\label{sec-introduction}
+
+\begin{dbremark}{Documentation: work in progress}{}
+This documentation is a work in progress. Readers finding errors or with comments are invited to send them via the email address on the title page.
+\end{dbremark}
+
+\begin{dbwarning}{Class to be used}{}
+  The \gls{nwejm} provides two \LaTeX{} classes:
+  \begin{enumerate}
+  \item The \nwejmcl{} designed for entire issues of the journal, and thus intended for the \nwejm{} managing team (and not for authors of articles);
+  \item The \nwejmauthorcl{} for authors of articles to be published in \gls{nwejm}.
+  \end{enumerate}
+  Authors of articles should therefore take care to use the \nwejmauthorcl{}
+  and \emph{not} the \nwejmcl{}.
+\end{dbwarning}
+
+\begin{dbwarning}{Required packages}{}
+  In order to use the \nwejmauthorcl{}, it is necessary to have:
+  \begin{itemize}
+  \item A reasonably recent \hologo{TeX} distribution;
+  \item The \Package{biblatex};
+  \item The
+    \href{https://www.ctan.org/pkg/biber}{\program{biber}}\footnote{Attention!
+      The bibliography must be compiled not with the usual
+      \program{bibtex}, but with \program{biber}. More details in
+      \vref{wa-affichage-auteurs} and \vref{sec-bibliographie}.} program.
+  \end{itemize}
+  With Ubuntu for example, if \hologo{TeX}~Live is installed via the GNU/Linux distribution packages, those named \package{texlive-bibtex-extra} and
+  \package{biber} are required.
+\end{dbwarning}
+
+The \LaTeX{} class \nwejmauthor{} is intended for authors wishing to publish an article in  \href{http://math.univ-lille1.fr/~nwejm/}{\gls{nwejm}}. The purpose of this class is:
+\begin{enumerate}
+\item To accurately reproduce the \nwejm{}'s layout, allowing thus authors to work on the layout of their document under real conditions;
+\item To provide some tools (commands et environments) to facilitate the writing of documents, especially those containing mathematics.
+\end{enumerate}
+
+\begin{dbwarning}{\protect\lstinline+UTF-8+ input encoding required}{}
+  The \nwejmauthorcl{} of \nwejm{} relies crucially on ×UTF-8× input encoding:
+  \begin{itemize}
+  \item It loads the \Package{inputenc}\footnote{%
+      It is therefore advisable \emph{not} to load this package: see \vref{sec-canevas-de-fichier} for an outline of the source file for \nwejm{} and in particular for a typical preamble.%
+      %
+    }
+    %
+    with the \docAuxKey{utf8} option;
+  \item It assumes that  \file{.tex} source files are indeed encoded in ×UTF-8×: make sure that your computer editor is correctly set for this input encoding.
+  \end{itemize}
+\end{dbwarning}
+
+\begin{dbwarning}{Format and \hologo{pdfLaTeX} compilation}{}
+  The composition of the \nwejm*{} volumes involves:
+  \begin{itemize}
+  \item The \hologo{LaTeX} format\footnote{In its \hologo{LaTeXe} version, the most
+      common today.}. Commands of other formats such as \hologo{plainTeX} should therefore be avoided;
+  \item The preferred compiler is \hologo{pdfLaTeX}. In particular, as the \hologo{LaTeX} is not used \emph{a priori}, we prefer:
+    \begin{enumerate}
+    \item \format{jpg}, \format{png} et
+      \format{pdf}\footnote{The recommended format is \format{pdf} since it is vector-based so that the quality of the images is not degraded by resizing.} as image formats;
+    \item Avoid \program{PostScript} code, especially via
+      \program{PSTricks}, and use the \Package{TikZ} as drawing tool
+      for instance.
+    \end{enumerate}
+  \end{itemize}
+\end{dbwarning}
+
+\section{Article's configuration}
+
+\subsection{Language}
+\label{sec:langue-de-larticle}
+
+The \nwejm{} accepts articles in four languages:
+\begin{itemize}
+\item English
+\item French
+\item German
+\item Dutch
+\end{itemize}
+and the \nwejmauthorcl{} allows to specify the language\footnote{The language is managed underhand by the \Package{babel}.} by using the following classes.
+% \refKey{english}, \refKey{french}, \refKey{ngerman} \refKey{dutch}
+
+\begin{docKey}{english}{}{no value, default option}
+  This option sets English as article language.
+\end{docKey}
+\begin{docKey}{french}{}{no value}
+  This option sets French as article language.
+\end{docKey}
+\begin{docKey}{german}{}{no value}
+  This option sets German as article language. It as \docAuxKey{ngerman} as alias.
+  \begin{dbremark}{\package*{babel} option underlying the \protect\refKey{german} option}{}
+    The \refKey{german} language option of \nwejmauthorcl{} calls underhand the \docAuxKey*{ngerman} option of \Package*{babel}.
+  \end{dbremark}
+\end{docKey}
+\begin{docKey}{dutch}{}{no value}
+  This option sets Dutch as article language.
+\end{docKey}
+
+\begin{dbremark}{Default article language}{}
+  If none of these options are specified, the default language is English.
+\end{dbremark}
+
+\subsection{Other configurations}
+\label{sec:autr-conf}
+
+\begin{docCommand}{articlesetup}{\marg{options}}
+  This command allows you to configure the \meta{options} of the current article in key/value form.
+
+  The only key provided for the time being is \refKey{gradient}.
+  \begin{docKey}{gradient}{=\docValue{grad}\textbar\docValue{nabla}}{no default value, initially \docValue{grad}}
+    This key allows you to specify how the gradient is displayed using the command \refCom{grad}.
+  \end{docKey}
+\end{docCommand}
+
+\begin{dbwarning}{\protect\refCom{articlesetup} command: not in the preamble!}{}
+  The\refCom{articlesetup} command must be \emph{exclusively} used in the body of the document (preferably just after ×\begin{document}×), otherwise the chosen configuration, although taken into account in the article alone, may not be taken into account in the complete volume!
+\end{dbwarning}
+
+\section{Preparing the article  \enquote{title}}
+\label{sec-prep-de-lart}
+
+This section lists commands, options and environment for \emph{preparing} the \enquote{title} of the article and its possible final part.
+
+\subsection{Title, subtitle}
+\label{sec-title}
+
+\begin{docCommand}[doc new=2017-10-23]{title}{\oarg{alternative title {\normalfont\ttfamily\acrshort*{toc}}}\oarg{header alternative title}\marg{title}}
+  This command defines for the current article:
+  \begin{itemize}
+  \item Its \meta{title} on the first page;
+  \item Its \emph{possible} \meta{alternative title
+      {\normalfont\ttfamily\acrshort*{toc}}} listed in:
+    \begin{itemize}
+    \item The volume in which the article will be published:
+      \begin{itemize}
+      \item In the \gls{toc};
+      \item In the bookmarks;
+      \end{itemize}
+    \item In the \textsc{pdf} file of the stand-alone article, in the \enquote{Title} metadata;
+    \end{itemize}
+  \item Its \emph{possible} \meta{header alternative title} as a header\footnote{\Ie{} in current title.} on even-numbered pages.
+  \end{itemize}
+  The precise use of this command is summarized in \vref{tab-commande-title}.

+\section{Bibliography}
+\label{sec-bibliographie}
+
+To compose bibliographies, the \nwejmauthorcl{} uses modern tools such
+as the \Package*{biblatex} and  \hologo{biber} engine. Their use can
+be summarized as follows\autocite[for more details, see e.g.][in French]{Bitouze}.
+\begin{enumerate}
+\item Build a bibliographic database in a \meta{bibliographic file}\footnote{Such
+    files have a \file{.bib} extension.}.
+
+  To do this, we recommend to use a dedicated software,
+  \href{http://jabref.sourceforge.net/}{\program{JabRef}} for
+  instance, configured via the menu
+  \menuentry{Options>Preferences>General} and by choosing:
+  \begin{description}
+  \item[\menuentry{Default encoding} :] \menuentry{UTF8} ;
+  \item[\menuentry{Default bibliography mode} :] \menuentry{biblatex}.
+  \end{description}
+  By the way, we can change the interface language in the
+  \menuentry{Language} drop-down list.
+
+  Don't forget to assign a unique \meta{key} to each bibliographic
+  reference\footnote{In \program{JabRef}, the 
+    \enquote{magic wand} or key icon helps to generate the  \meta{key}.}.
+\item In the \file{.tex} source file: 
+  \begin{enumerate}
+  \item \emph{In the preamble}, use the \docAuxCommand{addbibresource}
+    command to specify the \meta{bibliographic file}:
+\begin{preamblecode}[listing options={alsolanguage={[biblatex]TeX}}]
+\addbibresource{"\meta{bibliographic file}".bib}
+\end{preamblecode}
+  \item In the body of the document, use the \docAuxCommand{autocite}
+    command\footnote{Preferably to the \docAuxCommand{cite}
+      command.}\footnote{The reference is then detailed in a
+      footnote.}  or, optionally,  the \docAuxCommand{textcite}
+    command\footnote{The reference is then displayed throughout the
+      text, but with less details.} from the \Package*{biblatex} to
+    cite  bibliographic references (each with a \meta{key}):
+\begin{bodycode}[listing options={alsolanguage={[biblatex]TeX}}]
+...\autocite{"\meta{key1}"}... \textcite{"\meta{key2}"} ...
+...\autocite{"\meta{key3,key4}"}... \textcite{"\meta{key5,key6}"} ...
+\end{bodycode}
+  \item At the end of the document, list the bibliographic
+    references by using the \refCom{printbibliography} command.
+  \end{enumerate}
+\item Perform the successive compilations \hologo{pdfLaTeX}, \hologo{biber}
+  and 
+  \hologo{pdfLaTeX}\suitecompilations.
+\end{enumerate}
+
+\begin{docCommand}{printbibliography}{}
+  This command produces the bibliographic references list entered
+  with respect to the  \Package*{biblatex} syntax. It has been
+  redefined to automatically display the possible
+  acknowledgements
+  (\refCom{acknowledgements} command) before the references list.
+\end{docCommand}
+
+For example, if the \File{.bib} contains:
+
+\begin{bodycode}[listing only,listing options={alsolanguage={[biblatex]TeX},deletekeywords={[2]series,geometry}}]
+@Book{            har,
+  author	= {Hartshorne, Robin},
+  title		= {Algebraic geometry},
+  note		= {Graduate Texts in Mathematics, No. 52},
+  publisher	= {Springer-Verlag},
+  address	= {New York},
+  date		= {1977}
+}
+@Book{		  laz1,
+  author	= {Lazarsfeld, Robert},
+  title		= {Positivity in algebraic geometry. I},
+  volume	= {48},
+  note		= {Classical setting: line bundles and linear series},
+  publisher	= {Springer-Verlag},
+  address	= {Berlin},
+  date		= {2004}
+}
+@Article{         shin,
+  author	= {Shin, Kil-Ho},
+  title		= {$3$-dimensional Fano varieties with canonical
+                  singularities},
+  journal	= {Tokyo J. Math.},
+  volume	= {12},
+  date		= {1989},
+  number	= {2},
+  pages		= {375-385}
+}
+\end{bodycode}
+
+then the following \file{.tex} source file:
+\begin{bodycode}[listing only,listing options={alsolanguage={[biblatex]TeX},deletekeywords={[1]theorem},deletekeywords={[2]first,and,see,theorem},deletekeywords={[3]theorem}}]
+The first assertion is a direct consequence of the Riemann-Roch

+  \item \package*{kpfonts} which provides all the standards symbols,
+    including those in the \Package{amssymb}, but also offers many others;
+  \item \package*{mathtools} which itself loads \package*{amsmath}
+    (but extends it and fixes some flaws), so that all the commands of
+    both packages are available;
+  \item \package*{rsfso} which provides nice calligraphic letters (via
+    the \docAuxCommand{mathscr} command);
+  \end{itemize}
+\item redefines some commands and provides some new ones, listed below;
+\item provides classical \enquote{theorem} environments (based on the
+  \package*{amsthm} and \package*{thmtools} packages), listed below.

+\subsubsection{Preset commands}
+
+The class provides some commands listed in \vref{com-paired}, enabling
+the entry of delimiter pairs, e.g. for norms, absolute values, etc.
+
+\begin{table}

+  \end{tabular}
+  \caption{Commands  enabling
+the entry of usual delimiter pairs}
+  \label{com-paired}
+\end{table}
+
+Since these commands all have the same syntax, only the
+\docAuxCommand{norm} command  is detailed.
+
+\begin{docCommand*}{norm}{\oarg{parameter size}\marg{argument}}
+  This command displays the norm of \meta{argument}.
+
+  The default delimeters height is automatically adjusted to the
+  height of the \meta {argument} but it is possible to specify a
+  \meta{size parameter} as an optional argument:
+  \begin{itemize}
+  \item \docValue{0}: default  delimiter size\footnote{Delimiter size in text mode.} ;
+  \item \docValue{1} or \docAuxCommand{big}: delimiter size larger
+    than the previous one;

+    than the previous one;
+  \item \docValue{4} or \docAuxCommand{Bigg}: delimiter size larger
+    than the previous one;
+  \end{itemize}
+\end{docCommand*}
+
+\begin{docCommand}{norm*}{\marg{argument}}
+  This command is equivalent to ×\norm[0]{×\meta{argument}×}×.

+\begin{dbremark}{Subscripts of delimiter pairs that do not have default ones}{}
+  It is always possible to manually add a subscript to a delimiter
+  pair command that does not have one by default.

+\end{bodycode}
+\end{dbremark}
+
+e\subsubsection{Defining new commands}
+
+New commands that facilitate the entry of delimiter pairs can be
+defined by using the  \refCom{NewPairedDelimiter} command.
+%
+\begin{docCommand}{NewPairedDelimiter}{\marg{command}\marg{options}}
+  This command defines a \meta{command} similar to the
+  \docAuxCommand{norm} command  but with left and right delimiters and
+  subscript specified in \meta{options} by using  the \refKey{left},
+  \refKey{right} and \refKey{subscript} keys.
+  \begin{docKey}{left}{=\meta{delimiter}}{no default value, initially empty}
+    This key is used to  specify the left \meta{delimiter} of the created \meta{command}.
+  \end{docKey}
+  \begin{docKey}{right}{=\meta{delimiter}}{no default value, initially empty}
+    This key is used to  specify the right \meta{delimiter} of the created \meta{command}.
+  \end{docKey}
+  \begin{docKey}{subscript}{=\meta{subscript}}{no default value, initially empty}
+     This key is used to  specify the \meta{subscript} of the
+     created \meta{command}.
+  \end{docKey}
+\end{docCommand}
+
+\NewPairedDelimiter{\floor}{
+  left=\lfloor,
+  right=\rfloor,
+  subscript=\text{eff}
+}
+\begin{preamblecode}[listing options={morekeywords={[2]left,right,subscript}}]
+\NewPairedDelimiter{\floor}{
+  left=\lfloor,
+  right=\rfloor,
+  subscript=\text{eff}
+}
+\end{preamblecode}
+\begin{bodycode}[listing and text]
+\begin{equation}
+\floor{\frac{A}{2}}
+\end{equation}
+\end{bodycode}
+
+\subsection{Operators}
+
+\subsubsection{Preset operators}
+
+\begin{docCommand}{dif}{}
+  This command displays the \enquote{$\dif$} differential operator used in particular in
+  integrals.
+\begin{bodycode}[listing and text]
+\begin{equation}
+\iiint_T f(x,y,z)\dif x \dif y \dif z=0
+\end{equation}
+\end{bodycode}
+\end{docCommand}
+
+\begin{docCommand}{grad}{}
+  This command displays the gradient:
+  \begin{itemize}
+  \item in the \enquote{$\grad$} form by default;
+  \item in the \enquote{$\nabla$} form if the \docValue{nabla} value
+    is put in the \refKey{gradient} key  in  argument of \refCom{articlesetup} command.
+  \end{itemize}
+\end{docCommand}
+
+\begin{docCommand}{Div}{}
+   This command displays the divergence operator: \enquote{$\Div$}.
+  \begin{dbremark}{No command \protect\docAuxCommand{div} for divergence}{}
+    The ×\div× command is already defined in \LaTeX{} and therefore
+    cannot be used for divergence.
+  \end{dbremark}
+\end{docCommand}
+
+\begin{docCommand}{curl}{}
+ This command displays the  rotational operator:
+ \enquote{$\curl$}. Its alias is \docAuxCommand{rot}.
+\end{docCommand}
+
+\begin{bodycode}[listing and text]
+\begin{align}
+  \Div  F & = \grad \cdot  F \\
+  \curl F & = \grad \wedge F
+\end{align}
+\end{bodycode}
+
+\begin{docCommand}{supp}{}
+  This command displays the support (of a function, of a measure, etc.):
+  \enquote{$\supp$}.
+\end{docCommand}
+
+\subsubsection{Defining new operators}
+
+New operators can be defined by using the usual  \refCom{DeclareMathOperator} command.
+
+\begin{docCommand}{DeclareMathOperator}{\marg{command}\marg{name}}
+  This command defines the \meta{command} displaying the operator
+  named \meta{name}.
+\end{docCommand}
+
+\begin{preamblecode}
+\DeclareMathOperator{\cat}{Cat}
+\end{preamblecode}
+\begin{bodycode}[listing and text,listing options={deletekeywords={example},deletekeywords={[4]all}}]
+A standard example is $\cat$, the $2$-category of all (small) ideals.
+\end{bodycode}
+
+\subsubsection{(Advanced use) Precautions for unusual binary operations}
+
+If, in binary  operations, an operator\footnote{Preset or defined with
+  the \protect\refCom{DeclareMathOperator} command.} is followed by a
+usual binary \LaTeX{} operator (\docAuxCommand{circ},
+\docAuxCommand{cdot}, \docAuxCommand{wedge}, etc.), the horizontal
+spaces between them will be correct.
+
+However, if the binary operator is not common, it should be declared by
+using the \refCom{BinaryOperators} command.
+
+\begin{docCommand}{BinaryOperators}{\marg{binary operators}}
+  This command ensures that the \meta{binary operators}\footnote{Separated
+    by commas.} will, in binary operations, properly space from the
+  preceding operators.
+\end{docCommand}
+
+\begin{preamblecode}[listing options={moretexcs={mybinop}}]
+\newcommand{\mybinop}{\mathbin{*}}
+\end{preamblecode}
+\begin{bodycode}[listing and text,listing options={moretexcs={mybinop}}]
+\begin{tabular}{>{$}l<{$}@{ : }l}
+  \grad \cdot    F & good     \\
+  \grad \mybinop F & bad \\ \BinaryOperators{\mybinop}%
+  \grad \mybinop F & good (thanks to \verb+\BinaryOperators{\mybinop}+)
+\end{tabular}
+\end{bodycode}
+
+\subsection{Miscellaneous}
+
+\begin{dbremark}{French-specific commands (bis)}{}
+  The following commands are only redefined for French articles.
+\end{dbremark}
+
+\begin{docCommand}{leq}{}
+  This command displays \enquote{\selectlanguage{French}$\leqslant$}.

+\begin{docCommand}{geq}{}
+  This command displays \enquote{\selectlanguage{French}$\geqslant$}.
+\end{docCommand}

+\subsection{Enumerations}
+\label{sec:list-dhyp-ou}
+
+To make the composition of enumerations (of hypothesis, assertions,
+conditions, etc.) easier, the  \nwejmauthorcl{} provides ready-to-use
+environments and allows to create new ones if needed (see the 
+\refCom{newenumeration} command).
+
+\subsubsection{Predefined enumerations}
+\label{sec:predefinies-:-listes}
+
+In mathematical articles, it is common to enumerate assertions,
+hypothesis or conditions and to refer to these. To do this, the
+\nwejmauthorcl{} provides three environments: \refEnv{assertions},
+\refEnv{hypotheses} and \refEnv{conditions}. Each assertion,
+hypothesis or condition is introduced by the \docAuxCommand{item} command.
+
+\begin{docEnvironment}[doclang/environment content=assertions]{assertions}{}
+  This environment composes a list of assertions.
+\end{docEnvironment}
+\begin{docEnvironment}[doclang/environment content=hypothesis]{hypotheses}{}
+  This environment composes a list of hypothesis
+\end{docEnvironment}
+\begin{docEnvironment}[doc new=2019-03-18,doclang/environment content=conditions]{conditions}{}
+  This environment composes a list of  conditions.
+\end{docEnvironment}
+
+\begin{bodycode}[listing and text,listing options={deletekeywords={[2]label}}]
+\begin{axiom}\label{my-axiom}
+  Each of the following assertions are admitted.
+  \begin{assertions}
+  \item\label{rare-expensive} Everything that is rare is expensive.
+  \item\label{horse}A cheap horse is rare.
+  \end{assertions}
+\end{axiom}
+According to the \vref{rare-expensive, horse} of \vref{my-axiom}, a
+cheap horse is expensive.
+\end{bodycode}
+
+\subsubsection{User-defined enumerations}
+
+If the enumerations provided by the  class are not enough, it is
+possible to create new ones via the \refCom{newenumeration} command.
+
+\begin{docCommand}[doc new=2019-03-18]{newenumeration}{\oarg{option(s)}\marg{name}}
+  This command create a new \LaTeX{}  environment , \meta{name}, which
+  is used as the usual \docAuxEnvironment{enumerate} environment of
+  ordered lists and in which each item is introduced by the
+  \docAuxCommand{item} command.
+
+\begin{preamblecode}
+\newenumeration{conventions}
+\end{preamblecode}
+\begin{bodycode}[listing and text]
+\begin{conventions}
+\item The horse is cheap.
+\item The horse is expensive.
+\end{conventions}
+\end{bodycode}
+
+We note that each listed item has a default label consisting of the
+initial of the \meta{name} indexed by an Arabic numeral, all in
+parentheses. If this label is not suitable, we can specify the desired
+one in  the \meta{option(s)} with the  \refKey{label} key.
+  \begin{docKey}{label}{={\meta{label}}}{no  default value, initially initial of \meta{name}}
+    This key is used to specify a \meta{label} different from the
+    initial of the environment \meta{name}.
+  \end{docKey}
+\renewenumeration[label=K]{conventions}
+\begin{preamblecode}

+\end{bodycode}
+
+Note that when cross-referencing using the \refCom{vref} (or
+\refCom{cref}) command\footnote{See \vref{sec-references-croisees}},
+the \meta{name} of the referenced enumerations is automatically added
+to the reference, in its singular or plural form as appropriate. By default,
+\begin{description}
+\item[The plural form] is the  \meta{name} ;
+\item[The singular form] is obtained by deleting the last
+  letter\footnote{Supposed to be an \enquote{s}.} of the  \meta{name}.
+\end{description}
+
+
+If these singular or plural forms must be built differently,  they
+should be specified in the \meta{option(s)} via
+the following \refKey{singular} and \refKey{plural} keys.
+  \begin{docKey}{singular}{={\meta{singular form of the
+          enumeration}}}{no default value,\\initially empty}
+    This key is used to specify the singular form of the enumeration.
+  \end{docKey}
+  \begin{docKey}{plural}{={\meta{plural form of the
+          enumeration}}}{no default value,\\initially empty}
+    This key is used to specify the plural form of the enumeration.

+\end{docCommand}
+
+If necessary, the \refCom{renewenumeration} command can be used to
+redefine an enumeration previously defined with the
+\refCom{newenumeration} command.
+
+\begin{docCommand}[doc new=2019-03-18]{renewenumeration}{\oarg{option(s)}\marg{name}}
+  This command redefines the enumeration environment \meta{name}. Its

+\section{Generalist commands}
+\label{sec:comm-gener}
+
+In addition to math-specific commands, the \nwejmauthorcl{} provides
+generalist commands to make easier the input of an article to be
+published in  \nwejm{}.
+
+
+\begin{docCommand}{ie(*)}{}
+  This command displays the phrase  \enquote{\ie*{}} translated into
+  the language of the article, in the form:
+  \begin{description}
+  \item[\emph{non} starred:] abbreviated to \enquote{\ie{}} ;
+  \item[starred:] in unabbreviated form \enquote{\ie*{}}.
+  \end{description}
+\end{docCommand}
+
+\begin{docCommand}{Ie(*)}{}
+  This command displays the phrase \enquote{\Ie*{}} translated into
+  the language of the article, in the form: 
+  \begin{description}
+     \item[\emph{non} starred:] abbreviated to \enquote{\Ie{}} ;
+  \item[starred:] in unabbreviated form \enquote{\Ie*{}}.
+  \end{description}
+\end{docCommand}
+
+\begin{docCommand}{century(*)}{\marg{number}}
+  This command displays the ordinal of the \meta{number}\footnote{This
+    number must be a non-zero integer, negative if
+    appropriate.}\footnote{In French and German,  \meta{number} is
+    written in Roman numerals and small capitals.} of a century,
+  followed by the word  \enquote{century} translated into the article language
+  and  by the possible mention that it is a century before our era. Thus:
+\begin{bodycode}[listing and text]
+In the \century{-1}, [...]. Later, in the \century{8}, [...]
+\end{bodycode}
+  The starred version displays only the ordinal (unless the  \meta{number} is
+  negative). Thus:
+\begin{bodycode}[listing and text]
+Agriculture in the \century*{-1} was [...].
+The poetry of the \century*{19} has profoundly marked [...].
+\end{bodycode}
+\end{docCommand}
+
+\begin{docCommand}{aside(*)}{\marg{text}}
+  This command allows you to compose  \meta{text} between long dashes.
+  \begin{description}
+  \item[In the non starred form,] it inserts the  \meta{text}  between
+    two long dashes.
+  \item[In the starred form,]  the \meta{text} is simply preceded by a
+    dash. This is to be used at the end of a sentence.
+  \end{description}
+  Thus :
+  \begin{bodycode}[listing and text]
+Experiences \aside{in the \enquote{real} word} have been triggered by digital experiences.   
+\end{bodycode}
+  and:
+\begin{bodycode}[listing and text,listing options={deletekeywords={example}}]
+It is suspected not  \aside*{for example it is expected that  $1/\pi$  is not a period}.
+\end{bodycode}
+\end{docCommand}
+
+\begin{docCommand}{nwejm}{}
+  This command displays:
+  \begin{description}
+  \item[In the \emph{non} starred form:] the abbreviated version \enquote{\nwejm{}};
+  \item[In the  starred form:] the \emph{non} abbreviated version \enquote{\nwejm*{}}.
+  \end{description}
+\end{docCommand}
+
+\section{Selection of tools from third party packages}
+
+This section lists some tools (commands and environments) provided by
+packages automatically loaded by the
+\nwejmauthorcl\footnote{L'\vref{sec-packages-charges-ou-pas} lists
+  those whose features may be useful for authors.}.
+
+\begin{dbwarning}{Non-exhaustive list of features from third party packages}{}
+  This lists is  \emph{non exhaustive}:
+  \begin{itemize}
+  \item Only a tiny fraction of the existing packages are loaded by
+    the class;
+  \item Only some of the packages loaded by the class are mentioned;
+  \item Only some features of the mentioned packages are
+    described. More information is available in the documentation of
+    these packages.
+  \end{itemize}
+\end{dbwarning}
+
+\subsection{Cross-referencing}
+\label{sec-references-croisees}
+
+\DeclareFixedFootnote{\objets}{Section, equation, theorem, figure,
+  array, etc.}
+
+The \Package*{cleveref} package makes cross-referencing powerful. In
+particular, it provides the following commands \refCom{cref} and \refCom{vref}.
+
+\begin{docCommand}{cref}{\brackets{\meta{label$_1$},...,\meta{label$_n$}}}
+  If one or more objects\objets{} are labelled with
+  \lstinline[deletekeywords={[2]label}]×\label{×\meta{label$_1$}×}×,...,
+  \lstinline[deletekeywords={[2]label}]×\label{×\meta{label$_n$}×}×, the command
+  \refCom{cref}:
+  \begin{itemize}
+  \item  displays their numbers\footnote{Surrounded by brackets where
+      customary, e.g. for equations.};
+  \item detects their nature\objets{} and displays the corresponding
+    keywords\footnote{Feature provided by the \Package{cleveref}
+      package.} before their numbers, automatically translated into
+    the article language\footnote{Feature
+      provided by the \nwejmauthorcl.}. 
+  \end{itemize}
+  %
+\begin{bodycode}[listing and text]
+Please refer to \cref{sec-title,sec-authors} [...]
+\end{bodycode}
+\end{docCommand}
+
+\begin{docCommand}{vref}{\brackets{\meta{label$_1$},...,\meta{label$_n$}}}
+  This command:
+  \begin{itemize}
+  \item includes the features of \refCom{cref};
+  \item displays\footnote{Or not, depending on the context.} the
+    (numbers of the) pages where they are located\footnote{Feature
+      provided by the \Package{varioref}.} after the numbers of
+    the referenced objects.
+  \end{itemize}
+
+  %
+\begin{bodycode}[listing and text]
+Please refer to \vref{sec-title,sec-authors} [...]
+\end{bodycode}
+\end{docCommand}
+
+\begin{dbremark}{Hyperlinks to a referenced object}{}
+  The numbers and  possible \aside{numbers of} pages of the
+  cross-references created with \refCom{cref} and \refCom{vref}
+ are hyperlinks to referenced objects\footnote{Feature provided by the \Package{hyperref}.}.
+\end{dbremark}
+
+% \begin{dbremark}{\docAuxCommand{ref} et \docAuxCommand{eqref} : clones de \protect\refCom{vref}}{}
+%   Les traditionnelles commandes \docAuxCommand{ref} et \docAuxCommand{eqref} ont
+%   été redéfinies par la \nwejmauthorcl pour fonctionner de façon identique
+%   à \refCom{vref}.
+% \end{dbremark}
+
+% \subsection{\enquote{Équations} (non-)numérotées}
+% \label{sec:equat-non-numer}
+%
+% Le lecteur, rompu à la composition de formules de mathématiques, connaît
+% certainement le \Package*{amsmath} et les environnements qu'il fournit :
+% \begin{itemize}
+% \item ×equation×, ×align×, ×gather×, ×multline× et ×flalign× qui numérotent
+%   leur contenu ;
+% \item ×equation*×, ×align*×, ×gather*×, ×multline*× et ×flalign*× qui \emph{ne}
+%   numérotent \emph{pas} leur contenu ;
+% \end{itemize}
+% et utilise les premiers si (et seulement si, théoriquement) les contenus
+% correspondants font l'objet de références croisées.
+%
+% Avoir à choisir entre les versions numérotées ou pas présente au moins deux
+% inconvénients pour l'utilisateur :
+% \begin{enumerate}
+% \item cela l'oblige à se poser à chaque fois la question de la pertinence de la
+%   numérotation de sa formule ;
+% \item son choix peut ultérieurement s'avérer caduc\footnote{Et donc nécessiter
+%     de passer par exemple d'un environnement étoilé à un non-étoilé \aside*{donc
+%       avec ajout d'un label}.}.
+% \end{enumerate}
+% Pour pallier cela, la \nwejmauthorcl{} charge automatiquement le
+% \Package{autonum} qui :
+% \begin{enumerate}
+% \item permet de ne recourir qu'aux environnements non-étoilés ;
+% \item assure automatiquement que les formules effectivement numérotées seront
+%   celles, et seulement celles, s'avérant faire l'objet de références croisées au
+%   sein du document.
+% \end{enumerate}
+%
+% \begin{bodycode}[listing and text]
+% L'\vref{euler-identity} mérite une référence croisée.
+% \begin{equation}\label{euler-identity}
+%   \E[\I\pi]+1=0
+% \end{equation}
+% C'est bien la seule ici.
+% \begin{equation}\label{not-interesting}
+%   0=0
+% \end{equation}
+% Malheureusement.
+% \begin{equation}
+%   1=1
+% \end{equation}
+% \end{bodycode}
+
+\subsection{Acronyms}
+\label{sec:acronymes}
+
+Acronyms often need to be used in mathematical articles. To this end,
+the \Package{glossaries}  offers a very efficient and simple feature:
+just use the commands:
+\begin{itemize}
+\item \refCom{newacronym} to \emph{define} an acronym;
+\item \refCom{gls} (or \refCom{acrshort}) to \emph{display} an acronym.
+\end{itemize}
+
+\begin{docCommand}{newacronym}{\marg{key}\marg{short form}\marg{long form}}
+  This command, best used in the preamble,  defines an acronym where:
+  \begin{enumerate}
+  \item \meta{key} identifies the acronym uniquely in the 
+    document\footnote{The author should be careful not to use the same
+      key twice  to identify different acronyms.};
+  \item \meta{short form} is  the acronym itself;
+  \item \meta{long form} is the meaning of the acronym.
+  \end{enumerate}
+\begin{dbwarning}{Short form of acronyms: in lowercase}{}
+  The \meta{short form} of an acronym has to be entered exclusively
+  in lowercase since it will be actually composed in small capitals.
+\end{dbwarning}
+\end{docCommand}
+
+\begin{docCommand}{gls}{\marg{key}}
+  This command displays the acronym identified by \marg{key}
+  according to the following principle:
+  \begin{enumerate}
+  \item The first occurrence of this command in the document displays
+    the acronym in its \emph{complete} form, \ie*{} its \meta{long
+      form} followed by its \meta{short form} in brackets;
+  \item The following ones  display the acronym only in \meta{short form}.
+  \end{enumerate}
+\end{docCommand}
+
+\begin{preamblecode}[listing options={alsolanguage={[glossaries]TeX}}]
+\newacronym{bap}{bap}{bounded approximation property}
+\end{preamblecode}
+\begin{bodycode}[listing and text,listing options={alsolanguage={[glossaries]TeX}}]
+\begin{enumerate}
+\item \gls{bap},
+\item \gls{bap}.
+\end{enumerate}
+\end{bodycode}
+
+\begin{docCommand}{acrshort}{\marg{key}}
+  This command displays  (only)  the \meta{short form} of the acronym,
+  whatever the  context\footnote{\Ie*{} even if it is the first time the acronym is used in the  document.}.
+\end{docCommand}
+
+\begin{dbremark}{The \refCom{acrshort} command: useful in a title}{}
+  The \refCom{acrshort} command can be useful in particular in the
+  article title where you do not want the full form of an acronym to
+  be detailed.
+\end{dbremark}
+
+The \Package*{glossaries} provides many other commands and
+features\autocite[For more  details, see for instance][]{Bitouze7}.
+
+\subsection{Quotes, citations}
+\label{sec-guillemets-citations}
+
+The \Package*{csquotes} is dedicated to formal and informal citations,
+and text excerpts. It includes the following easy-to-use \refCom{enquote}
+command.
+
+\begin{docCommand}{enquote}{\marg{text}}
+  This command composes the \meta{text} in quotation marks, automatically
+  adapted to:
+  \begin{itemize}
+  \item The typographic standards of the current language. It will
+    therefore be used whenever text is to be enclosed in quotes;
+  \item The level  (1 or 2) of \enquote{citation} in case of
+    nesting. It can therefore be used whenever text is to be
+    informally quoted.
+  \end{itemize}
+\begin{bodycode}[listing and text,listing
+  options={alsolanguage={[csquotes]TeX}}]
+he replied: \enquote{Courteline used to say: \enquote{To be taken for
+    an idiot in the eyes of an imbecile is the pleasure of a fine gourmet.}}
+\end{bodycode}
+\end{docCommand}
+
+\begin{docCommand}{blockcquote}{\marg{key}\marg{excerpt}}
+  This command allows you to quote an \meta{excerpt}
+  formally\footnote{\Ie*{} with details of the  source.}. The
+  corresponding bibliographic reference must be included in one of the
+   added \footnote{Using the  \docAuxCommand{addbibresource} command}  \file{.bib} files
+  and identified by the key \meta{key}.
+
+\renewcommand{\thempfootnote}{\arabic{mpfootnote}}
+\begin{bodycode}[listing and text,listing options={alsolanguage={[biblatex]TeX},alsolanguage={[csquotes]TeX},deletekeywords={[3]footnote}}]
+\citeauthor{Bitouze} specifies that:
+\blockcquote{Bitouze}{%
+  \textins{This} command composes the citations by detaching 
+  automatically from the current paragraph those which are
+  long.%
+}.
+\end{bodycode}
+% \footnote{By default, those exceeding  3~lines.}
+\renewcommand{\thempfootnote}{\alph{mpfootnote}}
+\end{docCommand}
+
+The \refCom{blockcquote} command has optional arguments allowing to
+add text \meta{prior} and/or \meta{subsequent} to the excerpt
+citation\autocite[For more details, see for instance][]{Bitouze}.
+
+% (\textsc{À suivre...})
+
+\subsection{Web addresses (\texorpdfstring{\acrshort{url}}{URL})}
+\label{sec-url}
+
+The \Package*{hyperref} provides (among other things) the \refCom{url}
+command, which makes it easy the display of web adresses, also known
+as \enquote{\gls{url}}, even if they contain special \TeX{} characters (×#×,
+%
+\lstinline[commentstyle={}]+%+,
+%
+×_×, ×~×, ×&×, etc.): these characters can therefore be entered as
+they are, unless the  \refCom{url} command is used in the argument of
+another command\footnote{For instance
+  \protect\docAuxCommand*{footnote}.}, in which case the ×#× and
+%
+\lstinline[commentstyle={}]+%+
+%
+characters must be preceded by the backslash command ×\×.
+
+\begin{docCommand}{url}{\marg{Web address}}
+  This command displays  the \meta{Web address} entered  \emph{as is}
+  and makes it a hypertext link.
+\begin{bodycode}[listing and text,listing options={alsolanguage={[hyperref]TeX},deletekeywords={[2]url}}]
+We refer to the instructions to authors on our website
+\url{http://math.univ-lille1.fr/~nwejm/#Authors}.
+\end{bodycode}
+\end{docCommand}
+
+\subsection{Lists  within paragraphs}
+\label{sec:listes-en-ligne}
+
+The reader is certainly familiar with the \docAuxEnvironment{itemize}, \docAuxEnvironment{enumerate} and
+\docAuxEnvironment{description} environments for creating respectively
+unordered\footnote{\enquote{Bulleted}.}, ordered\footnote{\Ie*{}
+  numbered} and \enquote{description} lists. The \Package*{enumitem}
+provides starred versions of these environments which compose these
+lists within the same paragraph\footnote{The first aim of this package
+  is to customize lists, but this is not recommended in the \nwejm{}
+  framework as it may contravene its typographic approach.}.
+
+\begin{docEnvironment}[doclang/environment content=list]{itemize*}{}
+  This environment composes a \enquote{bulleted} list.
+\end{docEnvironment}
+\begin{docEnvironment}[doclang/environment content=list]{enumerate*}{}
+   This environment composes a \enquote{numbered} list.

+
+\subsection{Packages loaded by the class}\label{sec:packages-charges-par}
+
+We have seen that, for several of its features, the  \nwejmauthorcl{}
+relies on automatically loaded packages. Those whose features can be
+useful to the authors of  \nwejm{}  articles are listed below. Their
+function and possible option(s) are indicated.
+
+In addition to the specific tools to the \nwejmauthorcl, all those
+provided by these different packages are therefore available to \nwejm{}
+authors.

+
+\subsection{Packages not loaded by the  class}\label{sec:packages-non-charges}
+
+The following list, for from being exhaustive, lists packages not
+loaded by the \nwejmauthorcl{} but which may prove useful to
+authors. In addition, when manually loaded, some of them have options
+or settings set by the \nwejmauthorcl{}, the most notable of which are specified. 
+
+\begin{description}
+\item[\package{tikz-cd}:] easy creation of very high quality
+  commutative diagrams\footnote{The \Package{xy}, often used for such
+    diagrams, is incompatible with the  present class:

+\item[\package{listings}:] insertion of computer listings;
+\item[\package{todonotes}:] insertion of
+  \enquote{TODO}\footnote{Reminders of points to add, complete,

+\end{description}
+
+\section{Incompatibilities}
+\label{sec-incompatibilites}
+
+For technical reasons, the \nwejm{} does not accept a \file{.tex}
+source file loading the \Package{xy} and the  \nwejmauthor{} will
+issue an error in that case. The user who has to compose
+\enquote{matrix-like} diagrams, and especially commutative diagrams,
+should use the modern and user-friendly \Package{tikz-cd}.
+
+\section{Notations, syntax, terminology and colour coding}\label{sec-synt-term-notat}
+
+We specify here the  notations, syntax, terminology and colour coding
+of this documentation.

+\subsection{Commands, environments, keys, values}\label{sec-comm-envir-cles}
+
+Commands, environments, keys and key values are systematically composed
+in monospaced font. In addition, to distinguish them easily, these are
+displayed with their own colours: 
+\begin{itemize}
+\item blue commands: \docAuxCommand*{command};
+\item \enquote{teal} environments:

+\subsection{Generic arguments}
+\label{sec-arguments-generiques}
+
+To explain the role of a command, it is sometimes necessary to
+indicate what it applies to. In other words, what its generic argument
+is.  Such an argument is composed:
+\begin{itemize}
+\item in monospaced  font;
+\item in italics;
+\item between single rafters;
+\end{itemize}
+all in brown, thus: \meta{generic argument}.
+
+\subsection{Hyperlinks}
+\label{sec-liens-hypertextes}
+
+Hyperlinks are shown in colour, as follows:
+\href{http://gte.univ-littoral.fr/members/dbitouze/pub/latex}{hyperlink}. Most
+references to commands, environments and keys defined in this document
+are hyperlinks, topped by the page number where the corresponding
+target is located (unless it is on the same page):
+\begin{itemize}
+\item \refCom{author};
+\item \refEnv{abstract}.
+\end{itemize}
+
+
+\subsection{\enquote{Mandatory} elements}
+\label{sec-comm-oblig}
+
+The \mandatory{} icon next to certain items (commands or
+environments) indicates that they are \enquote{mandatory}.
+
+\subsection{Source codes}
+\label{sec-codes-sources}
+
+The examples in this documentation consist of source code and, where
+appropriate, the corresponding \endquote{screen shots}.
+% Ceux-ci proviennent le plus souvent du spécimen de document composé avec la
+% \yatcl, fourni avec l'ensemble de la classe
+% (cf. \vref{sec-specimen-arborescence}).
+
+These source codes are shown in blue boxes, which may include a title:
+\begin{itemize}
+\item unshaded if they are to be entered in the body of the document;
+\begin{bodycode}
+"\meta{source code}"
+\end{bodycode}
+\begin{bodycode}[title=\meta{title}]
+"\meta{source code}"
+\end{bodycode}
+\item shaded if they are to be entered in the preamble of the file.
+\begin{preamblecode}
+"\meta{source code to be inserted in preamble}"
+\end{preamblecode}
+\begin{preamblecode}[title=\meta{title}]
+"\meta{source code to be inserted in preamble}"
+\end{preamblecode}
+\end{itemize}
+
+\subsection{Spaces in source code}
+\label{sec-espaces-dans-les}
+
+To avoid confusion, spaces in source code that must be entered using
+the keyboard are sometimes realized with the \lstinline[showspaces]+ +. mark.
+
+\subsection{Options}
+\label{sec-options}
+
+This class, and some of its commands and environments, can be adjusted
+with options, or lists of options (separated by commas). These options
+can be in the form \meta{key}×=×\meta{value}  and the inputted
+\meta{value} can be:
+%^^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[free.] If such a \meta{key} is for instance named
+  \refKey{freekey},  then it is documented according to the following syntax: 
+  \begin{docKey*}{freekey}{=\meta{value}}{\meta{default
+        and initial values}}
+    \meta{Description of \refKey{freekey}}
+  \end{docKey*}
+\item[imposed] (from a list of possible values). If such a \meta{key}
+  is for instance named \refKey{choicekey}  and with imposed values
+  \docValue*{value1}, \dots{}, \docValue*{valueN},  then it is
+  documented according to the following syntax\footnote{As is often
+    the case in computing, the vertical bar to separate the possible
+    values means \enquote{or}.}:
+  \begin{docKey*}{choicekey}{=\docValue*{value1}\textbar...\textbar\docValue*{valueN}}{\meta{default
+        and initial values}}
+    \meta{Description of \refKey{choicekey} and its possible values}
+  \end{docKey*}
+\end{description}
+%^^A \end{description}
+
+The \meta{default and initial values} of a key are often specified (in
+brackets at the end of a line). They indicate the value of the key: 
+\begin{description}
+\item[by default] i.e. when the key \emph{is} used \emph{alone}
+  i.e. without any explicit value imputed;
+\item[initially] i.e. when the key \emph{is not} used.
