Build Comment Web Pages option vanished

In VS.NET 2003 there used to be an option under Tools menu titled Build Comment Web Pages. I rarely used that feature in my projects but for some other reason I was looking for it. To my surprise it has vanished from there. I was pulling my hair for an hour and then gave up :-) Teemu Keiski pointed me to Sandcastle but then it is still in beta stage...

If anybody knows where it is immigrated or expelled then let me know. (No. I am not giving any awards for that :-)
