+% ltxnew provides the  \new, \renew and  \provide prefixes for checking
+% definitions. It is designed to work with e-TeX distributions of LaTeX
+% and relies on the LaTeX macro \@ifdefinable.
+%
+% Local  allocation  of counters,  dimensions,  skips,  muskips,  boxes,
+% tokens  and marks  are provided by the  etex.sty package.
+%
+% \new  and  \renew  as well  as  \provide  may be used  for all kind of
+% control sequences. Please refer to the section "Using \new" of the pdf
+% documentation.

+% \xpackage{ltxnew} provides \CSbf{new} \CSbf{renew} and \CSbf{provide}: three expandable prefixes
+% for use with |\def|, |\gdef|, |\edef|, |\xdef|, |\countdef|, |\dimendef|, |\skipdef|, |\muskipdef|,
+% |\box|, |\toksdef|, |\marks|, |\count|,
+% |\dimen|, |\skip|, |\muskip|, |\savebox|, |\toks| and the |\glob|\Repeat3\textasteriskcentered\
+% and |\loc|\Repeat3\textasteriskcentered\ variants of the \xpackage{etex} package.
+%
+% For example:§
+% \quad|\new\def\macro| will do {\it something like:} |\newcommand\macro{} \def\macro|§
+% \quad|\new\let\macro| will do {\it something like:} |\newcommand\macro{} \let\macro|
+%
+% ...But in fact |\new| does a little more than that...
+%
+% You may use |\new| or |\renew| for declaring macros, counters, dimensions, skips, muskips,
+% boxes, tokens and \eTeX's marks. Even with |\let|, |\new| can be used. Moreover, |\renew| can be used
+% to redefine macros that were previously defined as |\outer|.
+%
+% \xpackage{ltxnew} is designed to work with an \eTeX{} distribution of \LaTeX{}. It relies on the \LaTeX{} macro
+% |\@ifdefinable|, on the \Xpackage[etex-pkg]{etex} package and some macros of \Xpackage{etoolbox}.

+% \section{Introduction}
+%
+% \subsection{Motivation}
+%
+% \LaTeX{} provides |\newcommand| for defining new commands. However, comparing to |\def|
+% the syntax is limited because we cannot use delimited arguments in such a command.
+% The advantage of |\newcommand| (apart the optional argument\footnote{optional arguments are
+% implemented in a much flexible way by \xpackage{xargs} by Manuel P\'egouri\'e-Gonnard.})
+% is that the control sequence is first checked for availability (its meaning ought to be
+% |undefined| or |\relax| before the definition).
+%
+% \xpackage{etoolbox} enhance this matter allowing to define |\newrobustcmd| and |\renewrobustcmd|.
+%
+% Moreover, \LaTeX{} does not provide an automatic check of control sequences when defining
+% tokens (|\newtoks|), dimensions (|\newdimen|), skips (|\newskip|), etc. etc.
+
+% The only exceptions are:§
+% \begin{itemize}\itemsep=0pt
+% \item |\newlength| \\
+%     but there is no |\renewlength| command... because
+%     the name |\renewlength| sounds bad: it would have meant \textit{``I know the control sequence I wish
+%     to define as a length has been defined before, as a macro may be, or a box or a token or
+%     whatever, and I wish to redefine this control sequence to be a length (\textup{ie} a skip)}.
+%     So it doesn't really make sense...
+% \item |\newcounter| \\
+%     but |\newcounter{name}| does not define |name| but |\c@name| instead, as a counter.
+% \item |\newsavebox|
+% \item |\newfont|
+% \end{itemize}\restoreparskip
+%
+% \bfseries All those |\new|\Repeat{3}{\textasteriskcentered}\ stuff define control sequences globally,
+% \emph{excepting} |\newfont|.  The reason could to be found in the background\footnote{in fact, a new font
+% is defined as a control sequence, just like a macro, whereas skips, dimens, tokens etc. are numbered
+% and then, defining a new one require an allocation.}.
+%
+% \mdseries
+% But it's a matter of fact : \emph{fonts} are local to \LaTeX{} while \emph{length} (\emph{ie.\,skips})
+% are global...
+%
+% Thank to the \xpackage{etex} package that provides a method for the local allocation of new quantity
+% \xpackage{ltxnew} puts the state of the affairs in a better order. \xpackage{ltxnew} provides a way
+% to define new control sequences, or redefine them, just by
+% beginning the definition with a (expandable) prefix : |\new| or |\renew|.
+%
+% \subsection{What \cs{new} means...}
+%
+% Such a short and easy word as \texttt{new} ought to be defined !
+%
+% \bfseries \CS{new} means:§\mdseries
+% \begin{itemize}[label=--,topsep=0pt,itemsep=0pt]
+% \item Check if the control sequence to define is available (\emph{ie} means |undefined| or |\relax|)
+% \item If that's OK: go on (with a side effect if the package \xpackage{tracing} is loaded)
+% \item If not : throw an error, and if in |scrollmode| or |nonstopmode| or |batchmode| do not overwrite
+%       the last meaning.
+% \end{itemize}
+%
+% That is really what means |\new|. No more, no less.
+%
+% \subsection{What \cs{renew} means}
+%
+% \bfseries \CS{renew} means:§\mdseries
+% \begin{itemize}[label=--,topsep=0pt,itemsep=0pt]
+% \item Check if the control sequence to redefine already has a meaning (different from |undefined| and also from |\relax|)
+% \item If that's OK : go on (with a side effect if the package \xpackage{tracing} is loaded)
+% \item If not : throw an error. But if in |srollmode|, |nonstopmode| or |batchmode| \textbf{do define} the control sequence.
+% \end{itemize}
+%
+% \subsection{What \cs{provide} means}
+%
+% \bfseries \CS{provide} means:§\mdseries
+% \begin{itemize}[label=--,topsep=0pt,itemsep=0pt]
+% \item Check if the control sequence to define already has a meaning (different from |undefined| and also from |\relax|)
+% \item If that's OK : go on (with a side effect if the package \xpackage{tracing} is loaded)
+% \item If not : silently do nothing.
+% \end{itemize}
+%
+% \subsection{Using \cs{new}}
+%
+% |\new| acts as a (expandable) prefix with the following syntax:§

+\NeedsTeXFormat{LaTeX2e}% LaTeX 2.09 can't be used (nor non-LaTeX)

+% |\ltxn@expandonce| is the copy of the |\expandonce| macro from \Xpackage{etoolbox}.

+%
+% \subsection{The prefixes scanner}
+%
+% The prefixes scanner is very simple in fact! All the job is based of |\futurelet|: |\futurelet|
+% reads the next token but does not remove it from the input string. We then just have to test
+% it with |\ifx| to conditionally append it into the prefix buffer: |\ltxn@prfx|. Otherwise,
+% we expand the prefix once and try again. Namely:
+%
+% \quad|\futurelet\x\testmacro|\quad\smex\quad if |\testmacro| ``returned false'' then:§
+% \quad|\expandafter\futurelet\expandafter\x\expandafter\testmacro|
+%
+% easy easy easy...
+%
+% If it happens that the expanded prefix is the same before and after expansion, then it means that was
+% a primitive. The only primitives allowed between |\new| and |\def| are:§
+% \begin{centering}\begin{tabular}{*{4}{m{2.5cm}}}
+% |\long| & |\global| & |\protected| & |\outer| \\
+% |\expandafter| & |\noexpand| & \hfil \textit{and} & |\relax|
+% \end{tabular}\end{centering}
+%
+% \begin{macro}{\ltxn@prefix}
+% This is the prefix scanner. We open a group at the very beginning for all definitions
+% will be local until the final definition:
+% \iffalse
+%<package>
+%<package>% This is the entry point of the prefixes scanner:
+%<package>% The whole job is done by \futurelet
