\section{ Description}
Interwiki is a way of representing wiki pages on other wikis.  To mark an\newline
interwiki link, type the name of the site, a colon, then the name of the page\newline
on the interwiki site.\newline
Text\_Wiki needs to know the URL for the various interwiki sites so it make\newline
clickable links; to tell Text\_Wiki the site names and urls, use the\newline
\texttt{setRenderConf()\footnote{http://example.com/index.php?page=MethodSetRenderConf}} method.  The array key should be the\newline
name of the site, and the array value should be the URL part leading up to the\newline
page-value.\newline
\begin{verbatim}

// [snip] create a Text_Wiki object called $wiki
// set up an array of interwiki site names and urls
$sites = array(
    'MeatBall'    => 'http://www.usemod.com/cgi-bin/mb.pl?%s',
    'Advogato'    => 'http://advogato.org/%s',
    'Wiki'        => 'http://c2.com/cgi/wiki?%s'
);
// configure the interwiki rule
$wiki->setRenderConf('xhtml', 'interwiki', 'sites', $sites);
\end{verbatim}

\newline
\begin{quote}
\textbf{Note:} Note the use of \%s in the above URL strings; the \%s will be\newline
\end{quote}

    replaced by the page name.  If you specify a string that does not have a\newline
    \%s in it, Text\_Wiki will assume that the page name should go at the very\newline
    end of the string.\end{document}
