=head1 NAME

Template::Liquid::Tag::Comment - General Purpose Content Eater

=head1 Synopsis

    I love you{% comment %} and your sister {% endcomment %}.

=head1 Description

C<comment> is the simplest tag. Child nodes are not rendered so it effectively
swallows content.

    {% for article in articles %}
        <div class='post' id='{{ article.id }}'>
            <p class='title'>{{ article.title | capitalize }}</p>
            {% comment %}
                Unless we're viewing a single article, we will truncate
                article.body at 50 words and insert a 'Read more' link.
            {% endcomment %}
            ...
        </div>
    {% endfor %}

Code inside a C<comment> tag is not executed during rendering. So, this...

    {% assign str = 'Initial value' %}
    {% comment %}
        {% assign str = 'Different value' %}
    {% endcomment %}
    {{ str }}

...would print C<Initial value>.
