 =head1 NAME
 
-Test::Valgrind::Tool::SuppressionsParser - Mock Test::Valgrind::Tool for parsing valgrind suppressions.
+Test::Valgrind::Parser::Suppressions::Text - Parse valgrind suppressions output as text blocks.

 =head1 DESCRIPTION
 
-This class provides a default C<parse_suppressions> method, so that real tools for which suppressions are meaningful can exploit it by inheriting.
-
-It's not meant to be used directly as a tool.
+This is a L<Test::Valgrind::Parser::Text> object that can extract suppressions from C<valgrind>'s text output.

-=head2 C<new>
-
-Just a croaking stub to remind you not to use this class as a real tool.
+use Test::Valgrind::Suppressions;
 
-If your tool both inherit from this class and from C<Test::Valgrind::Tool>, and that you want to dispatch the call to your C<new> to its ancestors', be careful with C<SUPER> which may end up calling this dieing version of C<new>.
-The solution is to either put C<Test::Valgrind::Tool> first in the C<@ISA> list or to explicitely call C<Test::Valgrind::Tool::new> instead of C<SUPER::new>.

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