 \chapter{Presenting Theories}
 \label{ch:thy-present}
 
-Due to the previous chapters the reader should have become sufficiently
-acquainted with elementary theory development in Isabelle/HOL.  The following
-interlude covers the seemingly ``marginal'' issue of presenting theories in a
-typographically pleasing manner.  Isabelle provides a rich infrastructure for
-concrete syntax of the underlying $\lambda$-calculus language, as well as
-document preparation of theory texts based on existing PDF-{\LaTeX}
-technology.

-As has been pointed out by Leibniz\index{Leibniz, Gottfried Wilhelm} more than
-300 years ago, \emph{notions} are in principle more important than
-\emph{notations}, but fair textual representation of ideas is vital to reduce
-the mental effort in actual applications.
