+This layer does \f(CW\*(C`read\*(C'\fR and \f(CW\*(C`write\*(C'\fR operations by \fBmmap()\fRing the file if possible, but falls back to the default behavior if not.
+.SH "IMPLEMENTATION NOTE"
+.IX Header "IMPLEMENTATION NOTE"
+\&\f(CW\*(C`PerlIO::mmap\*(C'\fR only exists to use XSLoader to load C code that provides support for using memory mapped IO. One does not need to explicitly \f(CW\*(C`use PerlIO::mmap;\*(C'\fR.
