    <code class="code">//path/to:tool</code> will be built first and used from

    NB: For <code class="code">gentest()</code>, there's also
    <code class="code">test_tools</code> which behaves exactly the same, except
    is made available to <code class="code">test_cmd</code> instead.

    <code class="code">$TO
