=head1 NAME
Pod::Simple::Text -- format Pod as plaintext
=head1 SYNOPSIS
perl -MPod::Simple::Text -e \
"exit Pod::Simple::Text->filter(shift)->any_errata_seen" \
thingy.pod
=head1 DESCRIPTION
This class is a formatter that takes Pod and renders it as
wrapped plaintext.
Its wrapping is done by L<Text::Wrap>, so you can change
C<$Text::Wrap::columns> as you like.
This is a subclass of L<Pod::Simple> and inherits all its methods.
=head1 SEE ALSO
L<Pod::Simple>, L<Pod::Simple::TextContent>, L<Pod::Text>
