=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.
