/**
		<h2><a name="java">NiceUnit</a></h2>
		<h3>Description</h3>
		<p>Runs unit tests for a Nice package.</p>
		All arguments to the NiceUnit task have to be placed as attributes in the niceunit xml-element.
		<h3>Parameters</h3>
		<table border="1" cellpadding="2" cellspacing="0">
			<tr>
				<td valign="top"><b>Attribute</b></td>
				<td valign="top"><b>Description</b></td>
				<td align="center" valign="top"><b>Required</b></td>
			</tr>
			<tr>
				<td valign="top">package</td>
				<td valign="top">The Nice package to test.</td>
				<td align="center" valign="top">Yes</td>
			</tr>
			<tr>
				<td valign="top">classpath</td>
				<td valign="top">Search path for compiled packages and libraries.</td>
				<td align="center" valign="top">No</td>
			</tr>
		</table>

		<h4>classpath</h4>
		<p><code>NiceUnit</code>'s <i>classpath</i> attribute is a PATH like structure and can also be set via a nested
		<i>classpath</i> element. This is very reasonable if you want to make your build script's pathes platform
		independent. </p>
		<h5>Example</h5>
<pre>
	&lt;niceunit package=&quot;test&quot; &gt;
	  &lt;classpath&gt;
	    &lt;pathelement location=&quot;\test.jar&quot;/&gt;
	    &lt;pathelement path=&quot;${java.class.path}&quot;/&gt;
	  &lt;/classpath&gt;
	&lt;/niceunit&gt;
</pre>
		<p>It is possible to use the <i>classpath</i> attribute together with the
		<i>classpath<i> nested tag. In this case the result is a concatenated path.</p>
		<p>It is highly recommended to use the nested version!<p>


		<h3>Examples</h3>
<pre>
	&lt;taskdef name=&quot;niceunit&quot; classname=&quot;nice.tools.ant.NiceUnit&quot;/&gt;
	&lt;target name=&quot;nice-tests&quot;&gt;
	  &lt;niceunit package=&quot;test&quot; /&gt;
	&lt;/target&gt;
</pre>
