%   \cs\marksthe\M*{section}\M{content} &amp; Marks the \meta{content} into the named mark register \meta{section} in the same way as the \eTeX{} primitive \cs\marks:
%                                         in particular the \meta{content} is immediately expanded. \par
%                                         If the mark register does not exist, it is created (or allocated) with \cs\newmarks (in \xfile{etex.sty}).
%  \\
%  \cs\marksthe*\M*{section}\M{content} &amp; does the same but the \meta{content} is not expanded. The current values of counters, \cs\thesection \etc. will be wrong:
%                                         they will expand to the value they have at the time the mark register is read, not at the time of \cs\marksthe*.\par
%                                         Yet \cs\marksthe* is useful to mark a title only like in�

%                                         or to control the expansion (the \meta{content} can be expanded before marking in a way and with the protections desired by the user).
% \end{tabu*}
%
% Similarly \cs\marksthecs\M{subsubsection}\M{cs-name} marks the content of \cs{cs-name} by the mean of the named mark
% register \meta{subsubsection}. \meta{cs-name} is really the \emph{name of the control sequence} and not the control sequence itself:
% it does not start with \textttbf{\csname @backslashchar\endcsname}.�
% If \cs{cs-name} is empty the mark is empty, but if it is undefined or \cs\relax: nothing is marked: at reading time, the mark register never expands
% to \cs\undefined nor to \cs\relax.
%
% The syntax follows \eTeX{} \cs\marks primitive (a token-like syntax): braces are mandatory around the \M{content} to be marked, even if it is made of one single token.
%

% \end{declcs}\declcsbookmark\thefirstmarks\declcsbookmark\thebotmarks\declcsbookmark\thetopmarks

% Pretty often we want to compare the botmarks against the firstmarks or the topmarks, to adapt the header and/or footer
% in case those marks are equal or different, \ie in case the page contains a new section title or not:

% \cs\ifmarksequal expands the code in the \M{true} or the \M{false} part if the extraction of the marks are equal
% (in the sense of \cs\ifx) or different.
%
% If any of the marks register\, \cs{marks@\meta{named-mark}}\, does not exist the \M{false} part is expanded.
%
% If marks are used both at \cs\sectionmark \textbf{and at} \cs\sectionbreak then the following assertions are true:�

% \cs\firstmarks &amp;\cs\botmarks &amp;there is at most one section title on the current page; \\

% \cs\showthemarks is for debugging purpose: it prints a message in the \xext{log}* and the ``standard error'' with
% the contents of the marks \cs\firstmarks, \cs\botmarks and \cs\topmarks for the \meta{named-mark} register given.
% Then it executes \cs\show on the extracted content of \cs\firstmarks in order to stop compilation at that point:
% the console displays the contents of \cs\firstmarks, \cs\botmarks and \cs\topmarks.
