=head1 NAME

Test::Valgrind::Action::Suppressions - Generate suppressions for a given tool.

=head1 VERSION

Version 1.19

=cut

our $VERSION = '1.19';

=head1 DESCRIPTION

This action just writes the contents of the suppressions reports received into the suppression file.

=cut

use base qw<Test::Valgrind::Action Test::Valgrind::Action::Captor>;

=head1 METHODS

This class inherits L<Test::Valgrind::Action>.

=head2 C<new>

    my $tvas = Test::Valgrind::Action::Suppressions->new(
     name   => $name,
     target => $target,
     %extra_args,
    );

Your usual constructor.

You need to specify the suppression prefix as the value of C<name>, and the target file as C<target>.

Other arguments are passed straight to C<< Test::Valgrind::Action->new >>.
