+env.DocbookHtml(['manual.html','reference.html'], ['manual.xml','reference.xml'])

+<important xmlns="http://www.scons.org/dbxsd/v1.0"><para>Whenever you leave out the list of sources, you may not specify a file extension! The

+</para>
+</important>
+<para xmlns="http://www.scons.org/dbxsd/v1.0">The rules given above are valid for the Builders <link xmlns="http://www.scons.org/dbxsd/v1.0" linkend="b-DocbookHtml"><function>DocbookHtml</function></link>, 
+<link xmlns="http://www.scons.org/dbxsd/v1.0" linkend="b-DocbookPdf"><function>DocbookPdf</function></link>, <link xmlns="http://www.scons.org/dbxsd/v1.0" linkend="b-DocbookSlidesPdf"><function>DocbookSlidesPdf</function></link> and <link xmlns="http://www.scons.org/dbxsd/v1.0" linkend="b-DocbookXInclude"><function>DocbookXInclude</function></link>. For the 
+<link xmlns="http://www.scons.org/dbxsd/v1.0" linkend="b-DocbookMan"><function>DocbookMan</function></link> transformation you
+can specify a target name, but the actual output names are automatically
+set from the <literal>refname</literal> entries in your XML source.
+</para>
+
+<para xmlns="http://www.scons.org/dbxsd/v1.0">The Builders <link xmlns="http://www.scons.org/dbxsd/v1.0" linkend="b-DocbookHtmlChunked"><function>DocbookHtmlChunked</function></link>, <link xmlns="http://www.scons.org/dbxsd/v1.0" linkend="b-DocbookHtmlhelp"><function>DocbookHtmlhelp</function></link> and

+<listitem><para>the main target is always named <filename>index.html</filename>, i.e. the output name for the
+XSL transformation is not picked up by the stylesheets.
+</para>
+</listitem>
+</orderedlist>
+<para xmlns="http://www.scons.org/dbxsd/v1.0">As a result, there is simply no use in specifying a target HTML name.

+</para>
+<screen xmlns="http://www.scons.org/dbxsd/v1.0">env = Environment(tools=['docbook'])
+env.DocbookHtmlhelp('manual')
+</screen>
+
+<para xmlns="http://www.scons.org/dbxsd/v1.0">If you want to use a specific XSL file, you can set the
+additional <literal>xsl</literal> parameter to your
+Builder call as follows:
+</para>
+<screen xmlns="http://www.scons.org/dbxsd/v1.0">env.DocbookHtml('other.html', 'manual.xml', xsl='html.xsl')
+</screen>
+<para xmlns="http://www.scons.org/dbxsd/v1.0">Since this may get tedious if you always use the same local naming for your customized XSL files,
+e.g. <filename>html.xsl</filename> for HTML and <filename>pdf.xsl</filename> for PDF output, a set of
+variables for setting the default XSL name is provided. These are:
+</para>
+<screen xmlns="http://www.scons.org/dbxsd/v1.0">DOCBOOK_DEFAULT_XSL_HTML
