proof process, the library comes with a comprehensive set of theorems that cover
not only these notions, but also some extensions such as parametric integrals,
two-dimensional differentiability, asymptotic behaviors.  It also offers some
automations for performing differentiability proofs.  Moreover, Coquelicot is a
conservative extension of Coq's standard library and provides correspondence
theorems between the two libraries.")
