+section "Introduction"
+
+text{* This document is for those Isabelle users that have mastered
+the art of mixing \LaTeX\ text and Isabelle theories and never want to
+typeset a theorem by hand anymore because they have experienced the
+bliss of writing \verb!@!\verb!{thm[display]setsum_cartesian_product[no_vars]}!
+and seeing Isabelle typeset it for them:
+@{thm[display,eta_contract=false] setsum_cartesian_product[no_vars]}
+No typos, no omissions, no sweat!
+If you have not experienced that joy, read chapter 4, \emph{Presenting
+Theories}, of \cite{LNCS2283} first.
+
+If you have mastered the art of Isabelle's \emph{antiquotations},
+i.e.\ things like the above \verb!@!\verb!{thm...}!, beware: in your vanity
+you may be tempted to think that all readers of the stunning ps or pdf
+documents you can now produce at the drop of a hat will be struck with
+awe at the beauty unfolding in front of their eyes. Until one day you
+come across that very critical of readers known as the ``common referee''.
+He has the nasty habit of refusing to understand unfamiliar notation
+like Isabelle's infamous @{text"\<lbrakk> \<rbrakk> \<Longrightarrow>"} no matter how many times you
+explain it in your paper. Even worse, he thinks that using @{text"\<lbrakk>
+\<rbrakk>"} for anything other than denotational semantics is a cardinal sin
+that must be punished by immediate rejection.
+
+
+This document shows you how to make Isabelle and \LaTeX\ cooperate to
+produce ordinary looking mathematics that hides the fact that it was
+typeset by a machine. This involves additional syntax-related
+declarations for your theory file and corresponding \LaTeX\ macros. We
+explain how to use them but show neither. They can be downloaded from
+the web.

+
+text{* To print theorems as inference rules you need to include the
+\texttt{Rule} output syntax declarations in your theory and Didier
+Remy's \texttt{mathpartir} package for typesetting inference rules in
+your \LaTeX\ file.
+
+Writing \verb!@!\verb!{thm[mode=Rule] conjI[no_vars]}! produces
+@{thm[mode=Rule] conjI[no_vars]}, even in the middle of a sentence.
+The standard \texttt{display} attribute, i.e.\ writing
+\verb![mode=Rule,display]! instead of \verb![mode=Rule]!,
+displays the rule on a separate line using a smaller font:
+@{thm[mode=Rule,display] conjI[no_vars]}
+Centering a display does not work directly. Instead you can enclose the
+non-displayed variant in a \texttt{center} environment:
+
+\begin{quote}
+\verb!\begin{center}!\\
+\verb!@!\verb!{thm[mode=Rule] conjI[no_vars]} {\sc conjI}!\\
+\verb!\end{center}!
+\end{quote}
+also adds a label to the rule and yields
+\begin{center}
+@{thm[mode=Rule] conjI[no_vars]} {\sc conjI}
+\end{center}
+Of course you can display multiple rules in this fashion:
+\begin{quote}
+\verb!\begin{center}\isastyle!\\
+\verb!@!\verb!{thm[mode=Rule] conjI[no_vars]} {\sc conjI} \\[1ex]!\\
+\verb!@!\verb!{thm[mode=Rule] conjE[no_vars]} {\sc disjI$_1$} \qquad!\\
+\verb!@!\verb!{thm[mode=Rule] disjE[no_vars]} {\sc disjI$_2$}!\\
+\verb!\end{center}!
+\end{quote}
+yields
+\begin{center}\isastyle
+@{thm[mode=Rule] conjI[no_vars]} {\sc conjI} \\[1ex]
+@{thm[mode=Rule] disjI1[no_vars]} {\sc disjI$_1$} \qquad
+@{thm[mode=Rule] disjI2[no_vars]} {\sc disjI$_2$}
+\end{center}
+Note that we included \verb!\isastyle! to obtain
+the smaller font that otherwise comes only with \texttt{display}.

+% They are two forms
+% \mathrule [label]{[premisses}{conclusions}
+% or
+% \mathrule* [options]{[premisses}{conclusions}
+%
+% Premisses and conclusions are lists of elements separated by \\
+% Each \\ produces a break, attempting horizontal breaks if possible,
+% and vertical breaks if needed.
+%
+% An empty element obtained by \\\\ produces a vertical break in all cases.
+%
+% The former rule is aligned on the fraction bar.
+% The optional label appears on top of the rule
+% The second form to be used in a derivation tree is aligned on the last
+% line of its conclusion
+%
+% The second form can be parameterized, using the key=val interface. The
+% folloiwng keys are recognized:
+%
+% width set the width of the rule to val
+% narrower set the width of the rule to val\hsize
+% before execute val at the beginning/left
+% lab put a label [Val] on top of the rule
+% lskip add negative skip on the right
+% llab put a left label [Val], ignoring its width
+% left put a left label [Val]
+% right put a right label [Val]
+% rlab put a right label [Val], ignoring its width
+% rskip add negative skip on the left
+% vdots lift the rule by val and fill vertical space with dots
+% after execute val at the end/right
+%
+% Note that most options must come in this order to avoid strange
+% typesetting (in particular lskip must preceed left and llab and
+% rskip must follow rlab or right; vdots must come last or be followed by
+% rskip.
