-%   \begin{docabstract}{Abstract}
-%     The package \pkg{ccool} for \LaTeX~is a \textit{key-value} interface, \nameref{usage:cs:ccool},
-%     on top of \pkg{xparse}'s document command parser. Global options control input processing and its expansion.
-%     By default, they are set to meet likely requirements, depending on context: the selected language,
-%     and which of text and math mode is active. These options can be overriden inline.
-%     This versality could find its use, for example, to encode notational conventions (such as \docexpand{\cs{Real}}{}|\mathbb{R}|)
-%     at the point where they are introduced in the \env{document} (``Let $\mathbb{R}$ denote real numbers'').
-%     Polymorphic commands can be generated by parameterizing the keys
-%     (for instance, one parameter value for style, another for a property).
-%     User input to \cs{Ccool} can optionally be serialized.
-%     This can useful for typesetting documents sharing the same notation.
-%   \end{docabstract}
-%   
-%   \selectlanguage{french}
-%   \begin{docabstract}{Résumé}
-%     L'extension~\pkg{ccool} pour \LaTeX~met à disposition une interface de type \textit{clé-valeur}, \nameref{usage:cs:ccool},
-%     destinée à faciliter la géneration de commandes. Les paramètres globaux contrôlant le traitement de ces \textit{clé-valeur} sont fixés
-%     par défaut pour répondre aux besoins courants, suivant le contexte (langage, mode textuel ou mathématique).
-%     Un exemple d'application, est la command-isation des conventions de notation (\docexpand{\cs{Reel}}{} |\mathbb{R}|),
-%     au point dans le \env{document} où elles sont introduites (``Soit~$\mathbb{R}$~les nombres réels.'').
