+=head1 Overview
+The most common IO operations are C<print> and C<say> for writing and
+C<lines> and C<get> for reading. All four are available as subroutines
+(defaulting to the C<$*OUT> and C<$*ARGFILES> file handles) and as
+methods on file handles.
+File handles are of type C<IO::Handle>, and can be created with C<&open>.
+Paths are generally passed as strings or C<IO::Path> objects.
+C<&dir> returns C<IO::File> and C<IO::Dir> objects, which are
+subclasses of C<IO::Path>.
