% \section{Introduction}
%
% \iffrenchdoc
%
% Cette toute petite extension a pour but de simplifier lﾃｩgﾃｨrement le
% dﾃｩboguage, notamment interactif, en fournissant quelques variantes de
% |\show| adaptﾃｩes aux objets introduits par \LaTeXe{} : commandes ﾃ�
% arguments optionnels, commandes robustes, environnements.
%
% \else
%
% This small package aims at making debugging (esp.\@ in an interactive
% way) easier, by providing |\show| variants suited to \LaTeXe's
% commands (with optional arguments or robust) and environments.
%
% \fi
%
% \section{Usage}
% 
% \iffrenchdoc
%
% \DescribeMacro{\showcmd}
% La commande |\showcmd| sert ﾃ� afficher une commande comme le ferait la
% primitive |\show| de \TeX, mais en effectuant en plus quelques tests
% pour savoir si la commande est une macro qui prend un argument
% optionnel (comme on peut en dﾃｩfinir avec |\newcommand|), ou qui a ﾃｩtﾃｩ
% dﾃｩfinie comme robuste avec |\DeclareRobustCommand|, ou ultﾃｩrieurement
% rendue robuste par |\MakeRobust| (fourni par \pf{fixltx2e}). Dans ce
% cas, la commande utilise aussi une ou plusieurs macros interne, que
% |\showcmd| affichera automatiquement pour vous.
%
% \DescribeMacro{\showcs}
% \DescribeMacro{\showenv}
% La variante |\showcs| fonctionne de la mﾃｪme maniﾃｨre, mais prend comme
% argument le \emph{nom} de la commande entre accolades : les deux
% formes |\showcmd\truc| et |\showcs{truc}| sont donc ﾃｩquivalentes.
% Enfin, |\showenv| montre les definitions de dﾃｩbut et de fin d'un
% environnement.
%
% \medbreak
%
% C'est tout pour la description des commandes. Il faut bien remarquer
% qu'elles ne sont pas infaillibles, et ne fonctionnent qu'avec les
% commandes crﾃｩes par les macros standard de \LaTeXe{} (et celles de
% \pf{xargs}, d'ailleurs) : elles n'essayent pas de prendre en compte
% des usages directs de |\@ifnextchar|, ni mﾃｪme de |\@ifstar| (pour le
% moment).
% 
% Pour les curieux, le code commentﾃｩ apparaﾃｮt ﾃ� la fin de la version
% anglaise de cette documentation
%
% \begin{center}\large
% C'est tout pour cette fois ! \\
% Amusez-vous bien avec \LaTeX{} !
% \end{center}
%
% \else
% 
% \DescribeMacro{\showcmd}
% The |\showcmd| command displays a command like \TeX's |\show|, but
% with a little bonus: it also checks if the macros takes an optional
% argument (like some commands defined with |\newcommand| do), or was
% made robust by using |\DeclareRobustCommand| or \pf{fixltx2e}'s
% |\MakeRobust|. Such commands use other(s) internal command(s), which
% |\showcmd| will also display for you.
%
% \DescribeMacro{\showcs}
% \DescribeMacro{\showenv}
% The |\showcs| command does the same thing as |\showcmd|, but takes the
% command's \emph{name} as its argument: |\showcmd\truc| is equivalent
% to |\showcs{truc}|. Finally, the |\showenv| command does the same for
% environments.
%
% \medbreak
%
% The previous commands will only work on simple commands defined with
% standard \LaTeXe{} commands (or, by the way, with \pf{xargs}): they
% do not try to guess such things as a direct use of |\@ifnextchar|, or
% even |\@ifstar| (at the moment).
