<para>When using the XSLT processor to manage dependencies and construct
the website, this parameter can be used to suppress the generation of
new and updated files. Effectively, this allows you to see what the
stylesheet would do, without actually making any changes.</para>
<para>Only applies when XSLT-based chunking is being used.</para>
