 \section{Introduction}
 \label{sec:intro}
-In this paper we describe the architecture and a few distintive features of the
-\emph{\MATITA} proof assistant. \MATITA{} was not conceived out of the blue
-one single day; it has been the next natural step in the evolution of one
-line of research we started six years ago. Thus, to better understand the
-system, we start from its historical roots.
