=head1 NAME
Test::Valgrind::Parser::Suppressions::Text - Parse valgrind suppressions output as text blocks.
=head1 VERSION
Version 1.19
=cut
our $VERSION = '1.19';
=head1 DESCRIPTION
This is a L<Test::Valgrind::Parser::Text> object that can extract suppressions from C<valgrind>'s text output.
=cut
use Test::Valgrind::Suppressions;

=head1 METHODS
=head2 C<report_class>
Generated reports are C<Test::Valgrind::Report::Suppressions> objects.
Their C<data> member contains the raw text of the suppression.
