-\section{Implementation}
-\label{sec:orgb1ea800}
-
-These document classes can only be used with \LaTeXe, so we make
-sure that an appropriate message is displayed when another \TeX{}
-format is used.
-
-\begin{lstlisting}
-\NeedsTeXFormat{LaTeX2e}[2020-10-01]
-\end{lstlisting}
-
-Now, we can announce the package name and its version:
-
-\begin{lstlisting}
-\ProvidesExplPackage{letgut-banner}
-{2022-03-22}
-{0.9.1}
-{
-  Package for the banner of the newsletter “La Lettre de GUTenberg”
-}
-\end{lstlisting}
-
-\subsection{Packages loaded}
-\label{sec:org09b0cd2}
-
-In order to provide class options, we load the \package{l3keys2e} which provides
-\LaTeXe{} option processing using \LaTeX3 keys:
-
-\begin{lstlisting}
-\RequirePackage{l3keys2e}
-\end{lstlisting}
-
-Till the Lua-based color will be  added to the core \package{l3color} approach,
-we have to rely on \package{xcolor}
-
-\begin{lstlisting}
-\RequirePackage{xcolor}
-\end{lstlisting}
-
-We want the material added to the first page to be not selectable in order to let the
-reader who wants to copy the interesting text be able to select it (see below).
-
-\begin{lstlisting}
-\RequirePackage{accsupp}
-\end{lstlisting}
-
-What follows has to be done at this end of the preamble, otherwise the font set
-with \lstinline+\setmainfont+ in the preamble isn't taken in account in the banner.
-
-We define an option for the color of the text in the “L” (that has to be the
-same as the page color of the document).
-
-\begin{lstlisting}
-\keys_define:nn { letgut-banner }
-{
-  , pagecolor .clist_gset:N = \g__letgutbanner_pagecolor_clist
-  , pagecolor .initial:n = { 1,1,1 }

-\subsection{Computations}
-\label{sec:orgdd18dd8}
-
-Determination of the widths of each of the letter boxes of the word “LETTRE”.
-\begin{lstlisting}
-\dim_const:Nn \c__letgutbanner_L_width_dim {
-  \box_wd:N \g__letgutbanner_L_box
-}
-\dim_const:Nn \c__letgutbanner_E_width_dim {

-\dim_const:Nn \c__letgutbanner_T_width_dim {

-}
-\dim_const:Nn \c__letgutbanner_R_width_dim {
-  \box_wd:N \g__letgutbanner_R_box
-}
-\end{lstlisting}
-Determination of the largest of these widths, stored in the scratch dimension
-\lstinline+\g_tmpa_dim+.
-\begin{lstlisting}
-\dim_gset:Nn \g_tmpa_dim {
-  \fp_eval:n {
-    max (
-    \c__letgutbanner_L_width_dim,
-    \c__letgutbanner_E_width_dim,
-    \c__letgutbanner_T_width_dim,
-    \c__letgutbanner_R_width_dim,
-    )
-  }pt
-}
-\end{lstlisting}
-Determination of the (1st) box whose width is the largest of all (\lstinline+argmax+, as
-it were).
-\begin{lstlisting}
-\box_gset_eq:NN \g__letgutbanner_largest_LETR_box \dim_case:nnF
-{ \g_tmpa_dim }
-{
-  { \c__letgutbanner_L_width_dim } { \g__letgutbanner_L_box }
-  { \c__letgutbanner_E_width_dim } { \g__letgutbanner_E_box }
-  { \c__letgutbanner_T_width_dim } { \g__letgutbanner_T_box }
-  { \c__letgutbanner_R_width_dim } { \g__letgutbanner_R_box }
-}
-{ No~ idea! }
-\end{lstlisting}
-Resize the box containing “GUTenberg” to the width of the text embedded in the
-horizontal bar of the “L”.
-\begin{lstlisting}
-\box_gresize_to_wd:Nn \g__letgutbanner_GUTenberg_box {
-  \c__letgutbanner_banner_horizontal_contents_width_dim
-}
-\end{lstlisting}
-Determination of the height and depth of the box containing “GUTenberg” resized.
-\begin{lstlisting}
-\dim_const:Nn \c__letgutbanner_GUTenberg_height_dim {
-  \box_ht:N \g__letgutbanner_GUTenberg_box
-}
-\dim_const:Nn \c__letgutbanner_GUTenberg_depth_dim  {
-  \box_dp:N \g__letgutbanner_GUTenberg_box
-}
-\end{lstlisting}
-Determining the size of the vertical offset of the box containing the resized
-“GUTenberg”, so that it is vertically centered in the horizontal bar of the “L”:
-the box positioned in \(0\) would be at the very bottom of the box containing the
-banner so with base line at the bottom the horizontal bar of the “L” so we raise
-it first by its depth (\(d\)) and then by half the difference between the heights
-(\(H\)) of the horizontal bar of the “L” and (\(h+d\)) total of the box containing
-“GUTenberg” resized (\(=d+H/2-(h+d)/2=(H-h+d)/2\)).
-\begin{lstlisting}
-\dim_const:Nn \c__letgutbanner_GUTenberg_yoffset_dim {
-  (
-  \c__letgutbanner_banner_thickness_dim
-  -
-  \c__letgutbanner_GUTenberg_height_dim
-  +
-  \c__letgutbanner_GUTenberg_depth_dim
-  )/2
-}
-\end{lstlisting}
-Once the height of the zone devoted to “La LETTRE” in the vertical bar of the
-“L” has been fixed, the line spacing between the letters of the word “LETTRE”
-depends in fact only on the width occupied by the widest of them, by definition
-equal to the width allocated to the text embedded in the vertical bar of the
-“L”. The latter, stored in \lstinline+\g__letgutbanner_banner_vertical_contents_width_dim+, is
-initially fixed:
-\begin{lstlisting}
-\dim_gset:Nn
-\g__letgutbanner_banner_vertical_contents_width_dim
-\c__letgutbanner_banner_vertical_contents_width_dim
-\end{lstlisting}
-but, to avoid this line spacing being too small (or even negative), we test that
-it is greater than a certain threshold, equal to a certain minimum percentage of
-the height common to the letters of the word “LETTRE”, stored in:
-
-\lstinline+\c__letgutbanner_leading_minimum_percent_fp+
-
-and fixed at 0.15. If this is not the
-case, we reduce (by 1pt):
-
-\lstinline+\g__letgutbanner_banner_vertical_contents_width_dim+
-
-and loop until it is the case.
-\begin{lstlisting}
-\dim_do_until:nNnn {
-  \g__letgutbanner_between_letters_vertical_space_dim
-}
->
-{
-  \fp_use:N\c__letgutbanner_leading_minimum_percent_fp
-  \g__letgutbanner_largest_LETR_box_height_dim

-\end{lstlisting}
-Resize the largest of these boxes to the width of the text embedded in the “L”.
-\begin{lstlisting}

-}
-\end{lstlisting}
-Resize the boxes for each of the letters in the word “LETTRE” so that they are
-all the same height as the widest of them.
-\begin{lstlisting}

-vertical bar.
-\begin{lstlisting}
-\box_gresize_to_wd:Nn \g__letgutbanner_La_box {
-  \g__letgutbanner_banner_vertical_contents_width_dim

-\end{lstlisting}
-Determine the height (\(h\)) and depth (\(d\)) of the resized box containing “La”.
-\begin{lstlisting}
-\dim_gset:Nn \g__letgutbanner_La_height_dim {

-}
-\dim_gset:Nn \g__letgutbanner_La_depth_dim  {
-  \box_dp:N \g__letgutbanner_La_box
-}
-\end{lstlisting}
-Determining the size of the vertical offset of the resized box containing “La”
-so that its top is, relative to the top of the “L”, offset by the same amount as
-the bottom of the box containing “GUTenberg” is offset from the bottom of the
-“L” (i.e., the distance from the top of the page to the top of “La” and the
-distance from the bottom of the page to the baseline of “GUTenberg” are
-identical).

-  \g__letgutbanner_La_depth_dim
-}
-\end{lstlisting}
-For the following, the area containing the letters of the word “LETTRE” aligned
-vertically is fixed, defined as follows:
-\begin{itemize}
-\item its top is the baseline of “La”,
-\item its bottom is the baseline of “GUTenberg”.
-\end{itemize}
-Determination of the height of this area.
-\begin{lstlisting}

-\end{lstlisting}
-Determining the vertical jump (\(s\)) between the letters in the word “LETTRE”
-with the constraints that:
-\begin{itemize}
-\item the top of the 1st letter (“L”) is \(3e/2\) below the top of the area (where
-\(e\) is the common vertical space separating the letters of the word
-“LETTRE”),
-\item the baseline of the last letter (“E”) is merged with the bottom of the area,
-\item this jump must not be less than 20 \% of the common height \(h\) to all these

-The sum of :
-\begin{itemize}
-\item the 5 vertical spaces (\(5e\)) between the letters in the word “LETTRE”,
-\item the 6 common heights (\(6h\)) to all these letters,
-\item \(3e/2\),
-\end{itemize}
-must equal the height (\(H\)) of the zone. So we have \(H=3e/2+5e+6h\), that is
-\(e=2(H-6h)/13\). Once initialized, the vertical jump between the letters is
-\(s=e+h\) that is \(s=(2H+h)/13\). Therefore:
-
-\begin{enumerate}
-\item Determine the vertical half-space between the letters.

-\begin{itemize}
-\item the distance between this top of page and the top of the vertical bar of

-\label{sec:orgef3017c}

-In order to provide class options, we load the \package{l3keys2e} which provides
-\LaTeXe{} option processing using \LaTeX3 keys:
-
-\begin{lstlisting}
-\RequirePackage{l3keys2e}
-\end{lstlisting}
-
-We define the 2 load time options for the target audience:
-
-\begin{itemize}
-\item \lstinline+for-readers+ (the default), for the “normal” “Lettre”,
-\item \lstinline+for-authors+, (only) the author(s) of an article of the “Lettre”.

-}
-\ProcessKeysOptions { letgut }
-\end{lstlisting}

-\subsection{Class and package loading}
-\label{sec:org464c4b7}
-
-The \letgutcls{} is based on the \lstinline+article+ class. It is by default two sided
-because of the alternating headers, and will by typeset with \lstinline+11pt+ as global
-font size.
-
-\begin{lstlisting}
-\LoadClass[twoside,11pt]{article}
-\end{lstlisting}
-
-We now load some packages.
-
-\begin{itemize}
-\item The \letgutcls{} will have to be used with LuaLaTeX. Hence the font selection
-package for XeLaTeX and LuaLaTeX.
-\begin{lstlisting}
-\RequirePackage{fontspec}
-\end{lstlisting}
-\item For subliminal refinements towards typographical perfection.
-\begin{lstlisting}
-\RequirePackage[
-, stretch=30
-, shrink=25
-, letterspace=150
-]{microtype}
-\end{lstlisting}
-\item Help in implementing paragraph layouts where the paragraphs are separated by
-a vertical space instead of (or in addition to) indenting them.
-\begin{lstlisting}
-\RequirePackage{parskip}
-\end{lstlisting}
-\item Extensive control of page headers and footers in \LaTeXe.
-\begin{lstlisting}
-\RequirePackage{fancyhdr}
-\end{lstlisting}

-\end{lstlisting}
-\item Select alternative section titles.
-\begin{lstlisting}

-\end{lstlisting}
-\item Context sensitive quotation facilities.
-\begin{lstlisting}
-\RequirePackage{csquotes}
-\end{lstlisting}
-\item Mathematical tools to use with (and which loads) \package{amsmath}.
-\begin{lstlisting}
-\RequirePackage[fleqn]{mathtools}
-\end{lstlisting}
-\item Better accessibility support for PDF files. This package is used because we
-want the material added to the background (banner on the first page and draft
-watermark) to be not selectable in order to let the reader who wants to copy
-the interesting text be able to select it.
-\end{itemize}
-\begin{lstlisting}
-\RequirePackage{accsupp}
-\end{lstlisting}
-\begin{itemize}
-\item A comprehensive (SI) units package.
-\begin{lstlisting}
-\RequirePackage{siunitx}
-\end{lstlisting}
-\item A collection of logos with bookmark support.
-\begin{lstlisting}
-\RequirePackage{hologo}

-\item Coloured boxes, for \LaTeX{} examples and theorems, etc.
-\begin{lstlisting}
-\RequirePackage{tcolorbox}
-\end{lstlisting}
-\item Expandable macros to extract the data from references and allow counter
-assignments or calculations.
-\begin{lstlisting}
-\RequirePackage{refcount}
-\end{lstlisting}
-\item Select colors with proper WCAG color contrast.
-\begin{lstlisting}
-\RequirePackage{ninecolors}
-\end{lstlisting}
-\item Typeset tabulars and arrays with LaTeX3 (for the alert boxes typeset as
-simple tabulars).
-\begin{lstlisting}
-\RequirePackage{tabularray}

-\end{lstlisting}
-\item Modifying the layout of floats.
-\begin{lstlisting}
-\RequirePackage{floatrow}
-\end{lstlisting}

-]{biblatex}
-\end{lstlisting}
-\item Typeset acronyms.
-\begin{lstlisting}
-\RequirePackage{acro}
-\end{lstlisting}
-\end{itemize}
-
-The following packages have to be the last ones loaded. So we ensure this by
-loading them just before the begining of the document:
-\begin{lstlisting}
-\AddToHook{begindocument/before}{
-\end{lstlisting}
-\begin{itemize}
-\item Extensive support for hypertext in \LaTeX{}
-\begin{lstlisting}
-\RequirePackage{hyperref}
-\end{lstlisting}
-\item Adjusting the anchors of captions
-\begin{lstlisting}
-\RequirePackage[all]{hypcap}
-\end{lstlisting}
-\item Intelligent cross-referencing
-\begin{lstlisting}
-\RequirePackage[french]{cleveref}
-\end{lstlisting}
-\end{itemize}
-We close the \lstinline+\AddToHook{begindocument/before}+ argument.
-\begin{lstlisting}
-}
-\end{lstlisting}
-
-\subsection{Settings for the loaded packages}
-\label{sec:orgbefd239}
-
-\begin{itemize}
-\item We switch to the French typographic conventions for \package{siunitx}.
-\begin{lstlisting}
-\sisetup{
-  , locale=FR
-  , mode=text
-}
-\end{lstlisting}
-\item Concerning floats, we ask:
-\begin{itemize}
-\item the caption text will be justified,
-\item the figures and their captions to be boxed (in order to distiguish them from
-the current text),
-\item the tables to have their captions above them.
-\begin{lstlisting}
-\DeclareMarginSet{hangleft}{
-  \setfloatmargins{\hskip-\c__letgut_hoffset_dim}{\hfil}
-}
-\DeclareFloatVCode{__letgut_ruleabove}{
-  \par\rule{\hsize}{.8pt}\vskip4pt\par
-  }
-\DeclareFloatVCode{__letgut_rulebelow}{
-  \par\vskip2pt\rule{\hsize}{.8pt}\par
-}
-\DeclareFloatStyle{__letgut_ruled}{
-  precode=__letgut_ruleabove,
-  postcode=__letgut_rulebelow,
-  % heightadjust=all,
-  floatwidth=.8\linewidth
-}
-\floatsetup{objectset=justified}
-\floatsetup[figure]{
-  style=__letgut_ruled,
-  margins=hangleft,
-  capposition=beside,
-  capbesideposition={top,left},
-  floatwidth=0.85\textwidth
-}
-\floatsetup[table]{capposition=top}
-\end{lstlisting}
-\end{itemize}
-Moreover, the tables will be entitled \enquote{tableau} instead of
-\enquote{table}.
-\begin{lstlisting}
-\renewcommand*\frenchtablename{Tableau}
-\end{lstlisting}
-\item We fix some defaults for the listings : we define a style for all the listings
-which resets all the \TeX{} control sequences/keywords and then load all the
-basic (La)\TeX{} dialects of \TeX{}. But we start with a dialect which is missing in
-the \package*{listings}.

-\end{lstlisting}
-\item We also create the new level \lstinline+\subtitle+ for the subtitles of the
-articles. They are dispayed uppercased (but in a smaller size than \lstinline+\title+).
-\begin{lstlisting}

-\end{lstlisting}
-\item By default (that is when \lstinline+\subtitle+ is not used), the toc levels of the
-sections, subsections, etc. are set to \lstinline+1+, \lstinline+2+, etc. But, when \lstinline+\subtitle+ is
-used, since this level has toc level \lstinline+1+, the toc levels of the sections,
-subsections, etc. have to be set to \lstinline+2+, \lstinline+3+, etc. And this has to be reset
-each time \lstinline+\title+ and  \lstinline+\subtitle+ are used.

+\item une \meta{liste de dialectes}, séparés par des virgules ;

+fournit la commande à arguments \enquote{verbatim} suivante.
+
+\begin{docCommand}{terminal}{\oarg{prompt}\oarg{options}\marg{stdin}\marg{stdout}}
+  %
+  Cette commande affiche les codes en entrée (\meta{stdin}) et en sortie
+  (\meta{stdout}), chacun des deux étant possiblement vide.
+
+  Le \meta{prompt}, ou \enquote{invite de commande}, est par défaut le symbole
+  \texttt{\$} affiché en rouge.
+
+  Il est possible de surcharger les réglages par défaut de cette commande au
+  moyen d'\meta{options} qui sont (toutes) celles acceptées par l'environnement
+  \docAuxEnvironment{tcblisting} et la commande \docAuxCommand{newtcblisting}
