destination file, as registered by `will_render`.
+If the second parameter is `undef`, the URL will be valid from any page on the
+wiki, or from the CGI; if possible it'll be a path starting with `/`, but an
+absolute URL will be used if the wiki and the CGI are on different servers.
+
If the third parameter is passed and is true, an absolute url will be
constructed instead of the default relative url.
