+=head1 NAME
+
+Pod::Plainer - Perl extension for converting Pod to old style Pod.
+
+=head1 SYNOPSIS
+
+  use Pod::Plainer;
+
+  my $parser = Pod::Plainer -> new ();
+  $parser -> parse_from_filehandle(\*STDIN);
+
+=head1 DESCRIPTION
+
+Pod::Plainer uses Pod::Parser which takes Pod with the (new)
+'CE<lt>E<lt> .. E<gt>E<gt>' constructs
+and returns the old(er) style with just 'CE<lt>E<gt>';
+'<' and '>' are replaced by 'EE<lt>ltE<gt>' and 'EE<lt>gtE<gt>'.
+
+This can be used to pre-process Pod before using tools which do not
+recognise the new style Pods.
+
+=head2 EXPORT
+
+None by default.
