<para>Normally first chunk of document is displayed when you open HTML
Help file. If you want to display another topic, simply set its
filename by this parameter.</para>

<para>This is useful especially if you don't generate ToC in front of
your document and you also hide root element in ToC. E.g.:</para>

<programlisting><![CDATA[<xsl:param name="generate.book.toc" select="0"/>
<xsl:param name="htmlhelp.hhc.show.root" select="0"/>
<xsl:param name="htmlhelp.default.topic" select="'pr01.html'"/>]]></programlisting>
