=head1 NAME
Test::Tester::Capture - Help testing test modules built with Test::Builder
=head1 DESCRIPTION
This is a subclass of Test::Builder that overrides many of the methods so
that they don't output anything. It also keeps track of it's own set of test
results so that you can use Test::Builder based modules to perform tests on
other Test::Builder based modules.
=head1 AUTHOR
Most of the code here was lifted straight from Test::Builder and then had
chunks removed by Fergal Daly <fergal@esatclear.ie>.
