=head1 NAME
PerlIO::mmap - Memory mapped IO
=head1 SYNOPSIS
open my $fh, '<:mmap', $filename;
=head1 DESCRIPTION
This layer does C<read> and C<write> operations by mmap()ing the file if possible, but falls back to the default behavior if not.
=head1 IMPLEMENTATION NOTE
C<PerlIO::mmap> only exists to use XSLoader to load C code that provides support for using memory mapped IO. One does not need to explicitly C<use PerlIO::mmap;>.
