=head1 NAME

Test::Builder::Formatter::LegacyResults - Encapsulate some legacy stuff.

=head1 DESCRIPTION

Older versions kept track of test results using an array of hashes. This is now
deprecated, but needs to still work for legacy code.

=head1 TEST COMPONENT MAP

  [Test Script] > [Test Tool] > [Test::Builder] > [Test::Bulder::Stream] > [Event Formatter]
                                                                                   ^
                                                                             You are here

A test script uses a test tool such as L<Test::More>, which uses Test::Builder
to produce results. The results are sent to L<Test::Builder::Stream> which then
forwards them on to one or more formatters. The default formatter is
L<Test::Builder::Fromatter::TAP> which produces TAP output.
