+nwejm - Support for the journal "North-Western European Journal of Mathematics"
+===============================================================================
+
+This bundle includes LaTeX classes and `biblatex` styles files dedicated to the
+new journal "North-Western European Journal of Mathematics".
+
+Follow development, submit issues, and suggest improvements at
+https://github.com/dbitouze/nwejm.
+
+Installation
+------------
+
+The classes are supplied in `.dtx` format.  If you want to unpack the `.dtx`
+yourself, running `tex nwejm.dtx` will extract the package whereas
+%
+`pdflatex nwejm` will typeset the documentation of the `nwejmart` class
+(currently only in French).
+
+Typesetting the documentation also requires a number of packages in addition to
+those needed to use the `nwejm` classes.  To compile the documentation without
+error, you will need, among others, my personal (dirty) package `denisbdoc` for
+documenting the classes I've written.

+% \section{Implementation}
+%
+%    \begin{macrocode}
+%<*class|class-article>
+%    \end{macrocode}
+%
+% We start by loading some packages that are required to define the \nwejmcl{}
+% (and its options). Since the latter will make use of the \pkg{expl3}
+% programming interface (\LaTeX3). In order to load this package, it is enough
+% to load the \Pkg{xparse} which is anyway needed to produce document-level
+% commands.
+%
+% \begin{itemize}
+% \item A generic document command parser:
+%    \begin{macrocode}
+\RequirePackage{xparse}
+%    \end{macrocode}
+% \item \LaTeXe{} option processing using \LaTeX3 keys:
+%    \begin{macrocode}
+\RequirePackage{l3keys2e}
+%    \end{macrocode}
+% \item Sorting lists (since \Pkg{l3sort} is about to move from `experimental'
+% to `stable' status, the \File{l3sort.sty} will be removed soonish):
+%    \begin{macrocode}
+\IfFileExists{l3sort.sty}{
+  \RequirePackage{l3sort}
+}{
+}
+% \item e-\TeX{} tools for \LaTeX:
+%    \begin{macrocode}
+\RequirePackage{etoolbox}
+%    \end{macrocode}
+% \end{itemize}
+%
+% In order to avoid ×_nwejm× in the name of each internal (i.e. private)
+% function and variable, we make use of the ×@@× place holder provided by the
+% \Pkg{l3docstrip}.
+%    \begin{macrocode}
+%<@@=nwejm>
+%    \end{macrocode}
+%
+% \subsection{\LaTeX3 loading}
+%
+% For debugging purpose, \Pkg{expl3} could be loaded with its
+% \docAuxKey*{check-declarations} option.
+%    \begin{macrocode}
+% \PassOptionsToPackage{check-declarations}{expl3}
+%    \end{macrocode}

+% \section{Packages loading}
+%
+%    \begin{macrocode}
+%<*class|class-article>
+%    \end{macrocode}
+%
+% Many of the \nwejmcl{} features are provided by third party packages. In this
+% section, we load them and outline their features interesting from the \nwejmcl{}
+% point of view.\todo{When possible, the list of loaded packages should be split
+% into two lists: one of the packages needed just by \nwejm{} (for both its logic
+% and its layout) and one of packages useful for the end user.}
+%
+% \begin{enumerate}
+% \item Selective filtering of error messages and warnings
+%    \begin{macrocode}
+\RequirePackage{silence}
+%    \end{macrocode}
+%
+% We filter harmless warnings (from \pkg{kpfonts}, \pkg{etex}, \pkg{etoc}).
+%    \begin{macrocode}
+\WarningFilter[nwejm]{kpfonts}{With 'easyscsl' option, don't fit together}
+\WarningFilter[nwejm]{etex}{Extended allocation already in use}
+\WarningFilter[nwejm]{etoc}{package tocvsec2 detected and its modification of}
+\ActivateWarningFilters[nwejm]
+%    \end{macrocode}
+%
+% \item Detecting and warning about obsolete \LaTeX{} commands:
+%    \begin{macrocode}
+\RequirePackage[l2tabu,orthodox]{nag}
+%    \end{macrocode}
+%
+% \item In case of \hologo{pdfTeX} engine, we enforce \pkg{fontenc} to be loaded
+%   with its \docAuxKey*{T1} option (usual for French and English documents) and
+%   \pkg{inputenc} to be loaded with its \docAuxKey*{utf8} option. Otherwise
+%   \pkg{fontspec}, convenient for both \hologo{XeLaTeX} and \hologo{LuaLaTeX},
+%   is loaded, with ligatures à la \TeX{} by default enabled.
+%    \begin{macrocode}
+\pdftex_if_engine:TF
+  {
+    \RequirePackage[T1]{fontenc}
+    \RequirePackage[utf8]{inputenc}
+  }{
+    \RequirePackage{fontspec}
+  }
+%    \end{macrocode}
+%
+% \item Compile \TeX{} pictures stand-alone or as part of a document:
+%    \begin{macrocode}
+%<class>\RequirePackage[group=false,subpreambles,sort]{standalone}%
+%    \end{macrocode}
+%
+% \item Formatting both header and footers (pagestyle), and sections headers:
+%    \begin{macrocode}
+\RequirePackage[pagestyles]{titlesec}%
+%    \end{macrocode}
+%
+% \item Graphics inclusion:
+%    \begin{macrocode}
+\RequirePackage{graphicx}%
+%    \end{macrocode}
+%
+% \item Establish input relative to a directory:
+%    \begin{macrocode}
+%<class>\RequirePackage{import}%
+%    \end{macrocode}
+%
+% \item Put a grey textual watermark on document pages (loaded only if
+% "forauthors" \nwejm{}'s option is on):
+%    \begin{macrocode}
+%<class>\bool_if:nT { \g_@@_for_authors_bool } {

+%    \begin{macrocode}
+\NewDocumentCommand \issuesetup { m } {
+%    \end{macrocode}
+%
+% Its keys are set (only "number", "month" and "year" are relevant here).

+\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 journal's
+% issue using the present class.} and a warning is emitted.

+%
+% 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}

+    }
+  }
+%    \end{macrocode}
+% \end{macro}
+%
+% If the "month" is not used, we replace "\g_@@_issue_month_int" ($=0$) by its

+% already provided by \Pkg{biblatex}, we will create a \file{.bib} file
+% containing "article" entries for each article of the \nwejm{} journal.
+%
+% This can be done only at the beginning of the document, in order to know the

+% make use of ×\setsecnumdepth{none}× from \Pkg{tocvsec2} and hence save the

+% \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 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}
+%
+% Then, we define a public command, similar to "\newtheorem", based on
+% "\_@@_new_theorem", that lets the user define his own theorems:
+%    \begin{macrocode}

+% We redefine the ×\blx@mkbibfootnote× macro in order the footnote mark of

+%
+% Because this cite style is a mix between ×authortitle× and ×authoryear× but is

+\newbibmacro*{cite:ibid}{%

+%
+% We create the ×nwejm:cite× bib macro which emulates a mix between
+% ×authortitle× and ×authoryear× styles: it displays the label name (mainly
+% authors' names), then the year and finally the title.
+%    \begin{macrocode}
