+ Matita is <strong>traditional</strong>. Its logical foundation is the
Calculus of (Co)Inductive Constructions (CIC). It can re-use
mathematical concepts produced by other proof assistants like
<a href="http://coq.inria.fr">Coq</a> and encoded in an
proof language is procedural in the same spirit of LCF. </p>
<p> Matita is <strong>innovative</strong>: </p>
