- <p>Creates a PostCSS plugin with a standard API.</p>

- <p>The plugin function receives 2 arguments: <a href="#root">Root</a>
- and <a href="#result">Result</a> instance. The function should mutate the provided
- <code>Root</code> node. Alternatively, you can create a new <code>Root</code> node
- and override the <code>result.root</code> property.</p>

- them as standalone tools.</p>
