<h2><a name="changelog">CvsChangeLog</a></h2>
<h3>Description</h3>
<p>Generates an XML-formatted report file of the change logs recorded in a
<a href="http://www.cvshome.org/" target="_top">CVS</a> repository. </p>
<p><b>Important:</b> This task needs "cvs" on the path. If it isn't, you will get
an error (such as error 2 on windows). If &lt;cvs&gt; doesn't work, try to execute cvs.exe
from the command line in the target directory in which you are working.

<h3>Parameters specified as nested elements</h3>
<h4><a name="user">user</a></h4>
<p>The nested <code>&lt;user&gt;</code> element allows you to specify a
mapping between a user ID as it appears on the CVS server and a name to
include in the formatted report.
Anytime the specified user ID has made a change in the repository, the
<code>&lt;author&gt;</code> tag in the report file will include
the name specified in <code>displayname</code> rather than the user ID.

<h4>Generate Report</h4>
<p>Ant includes a basic XSLT stylesheet that you can use to generate 
a HTML report based on the xml output. The following example illustrates
how to generate a HTML report from the XML report.</p>

<pre>
        &lt;style in="changelog.xml" 
               out="changelog.html" 
               style="${ant.home}/etc/changelog.xsl"&gt;
          &lt;param name="title" expression="Ant ChangeLog"/&gt;
          &lt;param name="module" expression="ant"/&gt;
          &lt;param name="cvsweb" expression="http://cvs.apache.org/viewcvs/"/&gt;
        &lt;/style&gt;
</pre>

<h4>Sample Output</h4>
<pre>
&lt;changelog&gt;
  &lt;entry&gt;
