7<h1>Orange Modules</h1>
8
9<p>Orange modules are intended to extend basic Orange's functionality, or provide wrappers for easier use of some data mining techniques. They are already included in normal Orange distribution. Following set of pages provides description, demos and examples for selected modules.</p>

11<P>Note: The documentation posted on the web is updated from the CVS in
12real-time and refers to the latest snapshot of Orange. If you encounter
13any inconsistencies please compare the standalone documentation with the
14one on the web.</P>
