they were defines as part of the
      <code class="code">outs</code> list:
    </p>

    <pre class="code-container">
      <!-- prettier-ignore -->
      <code data-lang="plz">
    Build finished; total time 230ms, incrementality 100.0%. Outputs:
    //:mocks:
      plz-out/gen/foo_mocks.go
      plz-out/gen/bar
      </code>
    </pre>

    <p>
      If instead of the folder <code class="code">plz-out/gen/bar</code>, it's
      preferable to have the output as
      <code class="code">plz-out/gen/bar/bar
