- =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.
