22 Matita (that means pencil in italian) is an experimental,

23 interactive theorem prover under development at the

24 <a href="http://www.cs.unibo.it">Computer Science Department</a> of the

25 <a href="http://www.unibo.it">University of Bologna</a>.

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.

57 The graphical interface has been inspired by CtCoq and

58 <a href="http://proofgeneral.inf.ed.ac.uk/">Proof General</a>.

59 It supports high quality bidimensional rendering of

60 proofs and formulae transformed on-the-fly to

61 <a href="http://www.w3.org/Math/">MathML</a> markup

80 (locally or on the World Wide Web) and

81 <a href="http://helm.cs.unibo.it/whelp/"> searched by means of

90 The tactical language, part of the proof language, has

91 step-by-step semantics, enabling inspection and replaying of deeply

92 structured proof scripts.
