=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>
