New in version 1.12: The verbatim tag was added in Twig 1.12 (it was named raw before).
The verbatim tag marks sections as being raw text that should not be parsed. For example to put Twig syntax as example into a template you can use this snippet:
{% verbatim %}
<ul>
{% for item in seq %}
<li>{{ item }}</li>
{% endfor %}
</ul>
{% endverbatim %}
Note
The verbatim tag works in the exact same way as the old raw tag, but was renamed to avoid confusion with the raw filter.
