=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.
