    use CCCP::ConfigXML as => 'singletone';
    
    # like XML::Bare
    my $cnf = CCCP::ConfigXML->new( file => ['foo_config.xml', 'bar_config.xml'] );
    
    # now, you can read
    $cnf->{foo}->{name}->{value};                        # TestApp
    $cnf->{foo}->{component}->{foo}->{value};            # bar
    $cnf->{foo}->{component}->{name}->{value};           # Controller::Foo    
    $cnf->{foo}->{model}->{qux}->{value}                 # Stop!
    
    $cnf->add_file(baz_config.xml);
    $cnf->{foo}->{model}->{qux}->{value}                 # Go!
