+At first sight, Matita looks as (and partly is) a Coq clone. This is
+more the effect of the circumstances of its creation described 
+above than the result of a deliberate design. In particular, we
+(essentially) share the same foundational dialect of Coq (the
+Calculus of Inductive Constructions), the same implementative
+language (Ocaml), and the same (script based) authoring philosophy.
+However, as we shall see, the analogy essentially stops here. 
+
+In a sense; we like to think of Matita as the way Coq would 
+look like if entirely rerwritten from scratch: just to give an
+idea, although Matita currently supports almost all functionalities of
+Coq, it links 60000 lins of coaml code, against ... of Coq (and
+we are convinced that, starting from scratch againg, we could furtherly
+reduce our code in sensible way).
