  37       Matita is based on the
  38       Calculus of (Co)Inductive Constructions, and is compatible, at some
  39       extent, with <a href="http://coq.inria.fr">Coq</a>.
  40       It is a reasonably small and simple application, whose
  41       architectural and software complexity is meant to be mastered by
  42       students, providing a tool particularly suited for testing innovative
  43       ideas and solutions.
  44       Matita adopts a tactic based editing mode; (XML-encoded) proof objects
  45       are produced for storage and exchange.
