import Public.Web;
object w = Wiki.RenderEngine(Wiki.RuleFile.default_rules);
w->render("this __is__ a\\\\ test...");

REAL USAGE

You'll probably want to impliment your own RenderEngine. Start by inheriting the RenderEngine 
and then impliment at least the following methods:

public void appendLink(String.Buffer buf, string name, string view, string|void anchor)

public void appendCreateLink(String.Buffer buf, string name, string view)

public int(0..1) showCreate()

public int(0..1) exists(string name)
