+5.14.0 C API available to XS modules running on older versions of
+Perl.  The features are centred around the function
+@code{cv_set_call_checker}, which allows XS code to attach a magical
+annotation to a Perl subroutine, resulting in resolvable calls to that
+subroutine being mutated at compile time by arbitrary C code.  This
+module makes @code{cv_set_call_checker} and several supporting
+functions available.")
