The WebRss topic in each web contains the following text:

-----
<pre>
&lt;channel rdf:about="%<nop>SCRIPTURL{"view"}%/%<nop>INCLUDINGWEB%">
  &lt;title>%<nop>WIKITOOLNAME%'s &lt;nop>%<nop>INCLUDINGWEB% web&lt;/title>
  &lt;link>%<nop>SCRIPTURL{"view"}%/%<nop>INCLUDINGWEB%&lt;/link>
  &lt;description>(the description of the web). TWiki is a Web-Based Collaboration Platform for the Enterprise.&lt;/description>
