+%   
+%   \begin{abstract}\pkg{oops}~is a package for \LaTeX~(hence ``scribe'') that organizes (typically mathematical) definitions
+%     along two dimensions: functions and objects, hence ``OO''. Such definitions are made \textit{inline} thanks to a minimalist interface built upon \pkg{xparse}\cite{xparse}. To make a definition, use \cs{OopsNew}\docmarg{\pkgargobj}, where \pkgargobj~identifies an object, followed by input that alternates between `text' and instructions.
+%     The latter create and expand definitions using rules that can be modified at the package level or themselves inline.
+%     This framework is suitable for instance where \pkgargobj~ is either of \texttt{ModelA} and \texttt{ModelB},
+%     and each requires its own definition of, say, a \textit{space}. In this case, they would be encoded respectively as \cs{Space}\docmarg{\texttt{ModelA}} and \cs{Space}\docmarg{\texttt{ModelB}}. However, this would be verbose if most functions applied to just one object, so the package provides a generic one that is set by default to \pkggenobjdefault. For example, \verb|\OopsNew{Math}[Let~]{Space=\Omega}[~denote the sample space]{}|, followed by \verb|$\Space$|, expand to:
+%     ``\OopsNew{Math}[Let~]{Space=\Omega}[~denote the sample space]{}'' and ``$\Space$''.
+%     Other features automate repetitive formatting tasks. Altogether, ``practical''.

+%   \begin{enumerate}[label=\alph*)]
+%   \item By default, all commands are declared in the \docbody~of \cs{documentclass}.
+%   \item Arguments expecting a \doctl\cite{tex.stack:104023}, \dockvl\cite[l3keys]{interface3}, a character, and \docinlcode, are denoted respectively
+%     \meta{tl}, \meta{kvl}, \meta{char}, and \meta{code}.
+%   \item \marg{arg} is either \texttt{m} or \texttt{g} options\cite{xparse}, and \docopto{\meta{arg}} and \docopte{\meta{char}}{\meta{arg}} are \texttt{o} and \texttt{e} options\cite{xparse}.
+%   \item If we say that \meta{option} can be used to override \meta{default}, and \meta{option} is \docnovalue\cite{xparse}, we will treat it as though \meta{option}$=$\meta{default}.
+%   \item We say ``set the key to'' as shorthand for ``set the value associated with the key to''
+%   \item We call \cs{code}\marg{arg}, \meta{code} with \verb|#1| replaced by \marg{arg}
+%   \end{enumerate}
+%   
+%   The template for the description of functions and arguments is, where applicable:

+% See \doclist{math:ii}. Low priority as there are workarounds.
+%
+% \section{Disclaimer}\label{other:discl}
+% 
+% This package has not been tested beyond \autoref{part:listing}.
+%
+% Option type \texttt{G} is supported but not recommended by \pkg{xparse}\cite{xparse}, but it's really practical in this case.
