 proving properties on numerical programs dealing with floating-point or
 fixed-point arithmetic.  It has been used to write robust floating-point
 filters for CGAL and it is used to certify elementary functions in CRlibm.
 While Gappa is intended to be used directly, it can also act as a backend
 prover for the Why3 software verification platform or as an automatic tactic
 for the Coq proof assistant.")
