standard way to interact with the system. Several procedural proof assistants
have either adopted or cloned Proof General as their main user interface.
The authoring interface of \MATITA{} is a clone of the Proof General interface.
+On the contrary, the interface to interact with the library is rather
+innovative and directly inspired by the Web interfaces to our Web servers.
-\TODO{item che seguono:}
-\begin{itemize}
- \item sistema indipendente (da \COQ)
- \item compatibilit\`a con sistemi legacy
-\end{itemize}
+\MATITA{} is backward compatible with the XML library of proof objects exported
+from \COQ{}, but, in order to test the actual usability of the system, we are
+also developing a new library of basic results from scratch.
