=head1 NAME

Pod::Simple::DumpAsText -- dump Pod-parsing events as text

=head1 SYNOPSIS

perl -MPod::Simple::DumpAsText -e \

"exit Pod::Simple::DumpAsText->filter(shift)->any_errata_seen" \

thingy.pod

=head1 DESCRIPTION

This class is for dumping, as text, the events gotten from parsing a Pod

document. This class is of interest to people writing Pod formatters

based on Pod::Simple. It is useful for seeing exactly what events you

get out of some Pod that you feed in.

This is a subclass of L<Pod::Simple> and inherits all its methods.
