/**
 * @author tomp 
 * 
 * Very simple Ant task for executing XQuery from within Ant build files. 
 * Simply set the queryfile= and/or some other options such as 
 * <tt>File outfile</tt>, <tt>boolean trace</tt> etc. <br/>
 * Example of an build file using this new (xquery) Ant task:
<pre>&lt;project name=&quot;XQueryExample&quot; default=&quot;main&quot; basedir=&quot;.&quot;&gt;

    &lt;property name=&quot;xmltools.home&quot; value=&quot;c:/devel/xml-tools&quot;/&gt;

    &lt;taskdef name=&quot;xquery&quot; classname=&quot;net.sf.tomp.xquery.ant.XQueryTask&quot;&gt;
        &lt;classpath&gt;
            &lt;fileset dir=&quot;${xmltools.home}/target/lib&quot;&gt;
                &lt;include name=&quot;*.jar&quot;/&gt;
            &lt;/fileset&gt;
            &lt;pathelement location=&quot;${xmltools.home}/target/xml-tools-1.0.jar&quot;/&gt;
        &lt;/classpath&gt;
    &lt;/taskdef&gt;

    &lt;target name=&quot;main&quot;&gt;
        &lt;xquery queryfile=&quot;tour.xq&quot; outfile=&quot;outfile.html&quot; verbose=&quot;yes&quot;/&gt;
    &lt;/target&gt;

&lt;/project&gt;</pre>
 It will give:<br/>
 <pre>Buildfile: build.xml

main:
   [xquery] net.sf.saxon.Query.main args=[-o, C:\devel\xml-tools\demo\outfile.html,
C:\devel\xml-tools\demo\tour.xq]

BUILD SUCCESSFUL
Total time: 2 seconds</pre>
