+statements, achieved by relying on total functions in place of dependent types
+for limits, derivatives, integrals, power series, and so on.  To help with the
+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.")
