  <varlistentry id="t-docbook">
    <term>docbook</term>
    <listitem><para>This tool tries to make working with Docbook in SCons a little easier.
It provides several toolchains for creating different output formats,
like HTML or PDF. Contained in the package is
a distribution of the Docbook XSL stylesheets as of version 1.76.1.
As long as you don't specify your own stylesheets for customization,
these official versions are picked as default...which should reduce
the inevitable setup hassles for you.
</para>
<para>Implicit dependencies to images and XIncludes are detected automatically
if you meet the HTML requirements. The additional
stylesheet <filename>utils/xmldepend.xsl</filename> by Paul DuBois is used for this purpose.
</para>
<para>Note, that there is no support for XML catalog resolving offered! This tool calls
the XSLT processors and PDF renderers with the stylesheets you specified, that's it.
The rest lies in your hands and you still have to know what you're doing when
resolving names via a catalog.
</para>
<para>For activating the tool "docbook", you have to add its name to the Environment constructor,
like this
</para>
<screen>env = Environment(tools=['docbook'])
</screen>
<para>On its startup, the &t-docbook; tool tries to find a required <literal>xsltproc</literal> processor, and
a PDF renderer, e.g. <application>fop</application>. So make sure that these are added to your system's environment
<envar>PATH</envar> and can be called directly without specifying their full path.
</para>
<para>For the most basic processing of Docbook to HTML, you need to have installed
</para>
<itemizedlist><listitem><para>the Python <systemitem>lxml</systemitem>
binding to <systemitem>libxml2</systemitem>, or</para>
</listitem>
<listitem><para>a standalone XSLT processor, currently detected are <application>xsltproc</application>, <application>saxon</application>, <application>saxon-xslt</application>
and <application>xalan</application>.
</para>
</listitem>
</itemizedlist>
<para>Rendering to PDF requires you to have one of the applications
<application>fop</application> or <application>xep</application> installed.
</para>

<para>Creating a HTML or PDF document is very simple and straightforward. Say
</para>
<screen>env = Environment(tools=['docbook'])
env.DocbookHtml('manual.html', 'manual.xml')
env.DocbookPdf('manual.pdf', 'manual.xml')
</screen>
<para>to get both outputs from your XML source <filename>manual.xml</filename>. As a shortcut, you can
give the stem of the filenames alone, like this:
</para>
<screen>env = Environment(tools=['docbook'])
env.DocbookHtml('manual')
env.DocbookPdf('manual')
</screen>
<para>and get the same result. Target and source lists are also supported:
</para>
<screen>env = Environment(tools=['docbook'])
env.DocbookHtml(['manual.html','reference.html'], ['manual.xml','reference.xml'])
</screen>
<para>or even
</para>
<screen>env = Environment(tools=['docbook'])
env.DocbookHtml(['manual','reference'])
</screen>
<important><para>Whenever you leave out the list of sources, you may not specify a file extension! The
Tool uses the given names as file stems, and adds the suffixes for target and source files
accordingly.
</para>
</important>
<para>The rules given above are valid for the Builders &b-link-DocbookHtml;,
&b-link-DocbookPdf;, &b-link-DocbookEpub;, &b-link-DocbookSlidesPdf; and &b-link-DocbookXInclude;. For the
&b-link-DocbookMan; 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>The Builders &b-link-DocbookHtmlChunked;, &b-link-DocbookHtmlhelp; and
&b-link-DocbookSlidesHtml; are special, in that:
</para>
<orderedlist><listitem><para>they create a large set of files, where the exact names and their number depend
on the content of the source file, and
</para>
</listitem>
<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>As a result, there is simply no use in specifying a target HTML name.
So the basic syntax for these builders is always:
</para>
<screen>env = Environment(tools=['docbook'])
env.DocbookHtmlhelp('manual')
</screen>

<para>If you want to use a specific XSL file, you can set the
additional <parameter>xsl</parameter> parameter to your
Builder call as follows:
</para>
<screen>env.DocbookHtml('other.html', 'manual.xml', xsl='html.xsl')
</screen>
<para>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>DOCBOOK_DEFAULT_XSL_HTML
DOCBOOK_DEFAULT_XSL_HTMLCHUNKED
DOCBOOK_DEFAULT_XSL_HTMLHELP
DOCBOOK_DEFAULT_XSL_PDF
DOCBOOK_DEFAULT_XSL_EPUB
DOCBOOK_DEFAULT_XSL_MAN
DOCBOOK_DEFAULT_XSL_SLIDESPDF
DOCBOOK_DEFAULT_XSL_SLIDESHTML
</screen>
<para>and you can set them when constructing your environment:
</para>
<screen>
env = Environment(
    tools=['docbook'],
    DOCBOOK_DEFAULT_XSL_HTML='html.xsl',
    DOCBOOK_DEFAULT_XSL_PDF='pdf.xsl',
)
env.DocbookHtml('manual')  # now uses html.xsl

Sets &consvars; for building Qt3 applications.
</para>

<note><para>
This tool is only suitable for building targeted to Qt3,
which is obsolete
(<emphasis>the tool is deprecated since 4.3</emphasis>).
There are contributed tools for Qt4 and Qt5, see
<ulink url="https://github.com/SCons/scons-contrib">
https://github.com/SCons/scons-contrib</ulink>.
Qt4 has also passed end of life for standard support (in Dec 2015).
</para></note>

<para>
Note paths for these &consvars; are assembled
using the <function>os.path.join</function> method
so they will have the appropriate separator at runtime,
but are listed here in the various
entries only with the <literal>'/'</literal> separator
for simplicity.
</para>

<para>
In addition, the &consvars;
&cv-link-CPPPATH;,
&cv-link-LIBPATH; and
&cv-link-LIBS; may be modified
and the variables
&cv-link-PROGEMITTER;, &cv-link-SHLIBEMITTER; and &cv-link-LIBEMITTER;
are modified. Because the build-performance is affected when using this tool,
you have to explicitly specify it at Environment creation:
</para>

<example_commands>
Environment(tools=['default','qt'])
</example_commands>

<para>
The &t-qt; tool supports the following operations:
</para>

<para>
<emphasis role="strong">Automatic moc file generation from header files.</emphasis>
You do not have to specify moc files explicitly, the tool does it for you.
However, there are a few preconditions to do so: Your header file must have
the same filebase as your implementation file and must stay in the same
directory. It must have one of the suffixes
<filename>.h</filename>,
<filename>.hpp</filename>,
<filename>.H</filename>,
<filename>.hxx</filename>,
<filename>.hh</filename>.
You can turn off automatic moc file generation by setting
&cv-link-QT_AUTOSCAN; to <constant>False</constant>.
See also the corresponding
&b-link-Moc; Builder.
</para>

<para>
<emphasis role="strong">Automatic moc file generation from C++ files.</emphasis>
As described in the Qt documentation, include the moc file at the end of
the C++ file. Note that you have to include the file, which is generated
by the transformation
<literal>${QT_MOCCXXPREFIX}&lt;basename&gt;${QT_MOCCXXSUFFIX}</literal>, by default
<filename>&lt;basename&gt;.mo</filename>. A warning is generated after building the moc file if you
do not include the correct file. If you are using &f-link-VariantDir;, you may
need to specify <parameter>duplicate=True</parameter>.
You can turn off automatic moc file generation by setting &cv-QT_AUTOSCAN; to
<literal>False</literal>. See also the corresponding
&b-link-Moc; Builder.
</para>

<para>
<emphasis role="strong">Automatic handling of .ui files.</emphasis>
The implementation files generated from <filename>.ui</filename>
files are handled much the same as yacc or lex files.
Each <command>.ui</command> file given as a source of &b-link-Program;,
&b-link-Library; or &b-link-SharedLibrary;
will generate three files: the declaration file, the
implementation file and a moc file. Because there are also generated headers,
you may need to specify <parameter>duplicate=True</parameter> in calls to
&f-link-VariantDir;.

&b-link-Uic; Builder.
