++ Description
Interwiki is a way of representing wiki pages on other wikis. To mark an
interwiki link, type the name of the site, a colon, then the name of the page
on the interwiki site.
Text_Wiki needs to know the URL for the various interwiki sites so it make
clickable links; to tell Text_Wiki the site names and urls, use the
{{[MethodSetRenderConf setRenderConf()]}} method. The array key should be the
name of the site, and the array value should be the URL part leading up to the
page-value.

// [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);


Note: Note the use of %s in the above URL strings; the %s will be
replaced by the page name. If you specify a string that does not have a
%s in it, Text_Wiki will assume that the page name should go at the very
end of the string.
