<section><title>XSLF Cookbook</title>
<p>
This page offers a short introduction into the XSLF API. More examples can be found in the
<link href="http://svn.apache.org/repos/asf/poi/trunk/src/examples/src/org/apache/poi/xslf/usermodel/"> XSLF Examples</link>
in the POI SVN repository.
</p>
<note>
Please note that XSLF is still in early development and is a subject to incompatible changes in a future release.
