[mod_python] And how to use <%@ include %> directive ?

How do you do, everybody.

Please, help me a little.

When I try to use include directive it includes nothing.
For example:

<%
if username == 'Greptham':
        #
%>
<%@ include file='/full/path/to/file' %>

, but it includes nothing... Unfortunately... Even if I just wrote:
<@ include file='/path/to/file' %>

How to use it?
