<h1>TimestampSelector</h1>
<p>The TimestampSelector task takes either a nested <path> element,
or a path reference, and sets either a named property, or a <code>path</code>
instance to absolute pathnames of the files with either the N latest or earliest
modification dates (based on the <code>age</code> attribute)</p>

<h2>Parameters specified as nested elements</h2>
<a name="path"><h3>path</h3></a>
<p><a href="http://ant.apache.org/manual/using.html#path">Path</a>
is used to select sets of files or directories in which to find the
most recently modified file</p>
<h2>Example</h2>
<h3>Using a path reference</h3>
<pre>
<code>
<path id="mypath">
<fileset dir="${log.dir}">
<include name="update*.log" />
</fileset>
<path>
<timestampselector property="most.recent.logs"
pathref="mypath" count="3"
pathsep=";" />
<echo message="${most.recent.logs}" />
</code>
</pre>
<h3>Using a nested <code>path</code> element</h3>
<pre>
<code>
<timestampselector property="most.recent.logs"
count="3"
pathsep=";" >
<path>
<fileset dir="${log.dir}">
<include name="update*.log" />
</fileset>
<path>
</timestampselector>
<echo message="${most.recent.logs}" />
</code>
</pre>
<h3>Outputing to a <code>path</code> element</h3>
<pre>
<code>
<timestampselector outputsetref="most.recent.logs"
pathref="mypath" count="3">
<path>
<fileset dir="${log.dir}">
<include name="update*.log" />
</fileset>
<path>
</timestampselector>
<copy todir="somedir">
