How can I use this in a page template?

The plugin is used when you call query_posts() from a theme template file so as to run your own query.

The following code is an example of what you could do to generate a list of the first 10 child pages from a parent page:

<div id="children">
        <dl>
        <?php query_posts('static=true&child_limit=10&child_of='.$id.'&order=ASC'); ?>
        <?php if(have_posts()) : while (have_posts()) : the_post(); ?>
        <dt><a href="<?php the_permalink();?>"><?php the_title();?>:</a></dt>
                <dd style=""><em><?php the_excerpt(); ?></em></dd>
        <?php endwhile; endif; ?>
        </dl>
</div>

How can I create a a page template which lists children of children?

If you want to create a hierarchical display with children of children then you will need to use nested loops which requires some care.

You will need to have the most up-to-date version of this plugin and then you can use the examples which are included with it in the page-templates folder.

The basic loops needed for a nested solution are as follows:

<div id="children">
        <dl>
        <?php query_posts('static=true&posts_per_page=-1&post_parent='.$id.'&order=ASC'); ?>
        <?php if(have_posts()) : while (have_posts()) : the_post(); ?>
        <?php   $inner_query = new WP_Query("post_type=page&posts_per_page=-1&post_parent={$id}&order=ASC");
                while ($inner_query->have_posts()) : $inner_query->the_post(); ?>
                    <dt><a href="<?php the_permalink();?>"><?php the_title();?>:</a></dt>
                    <dd style=""><em><?php the_excerpt(); ?></em></dd>
        <?php endwhile; endwhile; endif; ?>
        </dl>
</div>
