<h2><a name="changelog">ChangeLog</a></h2>
<h3>Description</h3>

<p>Generates an XML-formatted report file of the change logs recorded
in a <a href="http://subversion.tigris.org/"
target="_top">Subversion</a> repository. </p>

<p><b>Important:</b> This task needs "svn" on the path. If it isn't,
you will get an error (such as error 2 on windows). If
<code>&lt;svn&gt;</code> doesn't work, try to execute svn.exe from the
command line in the target directory in which you are working.</p>

<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 Subversion 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.</p>

<h4>Generate Report</h4>
<p>This antlib 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="your-path-to/etc/changelog.xsl"&gt;
          &lt;param name="title" expression="Jakarta BCEL ChangeLog"/&gt;
          &lt;param name="repo" expression="http://svn.apache.org/repos/asf"/&gt;
        &lt;/style&gt;
</pre>
