=head1 NAME

ExtUtils::testlib - add blib/* directories to $^INCLUDE_PATH

=head1 SYNOPSIS

  use ExtUtils::testlib;

=head1 DESCRIPTION

After an extension has been built and before it is installed it may be
desirable to test it bypassing C<make test>. By adding

    use ExtUtils::testlib;

to a test program the intermediate directories used by C<make> are
added to $^INCLUDE_PATH.
