Point the website to a new app instead of welcome app---web2py

Hi, this is a simple question I imagine. I uplaoded my app to the web2py admin interface. Now I would like to know how I can point the default website to this new app instead of the welcome app. Thanks for the help.

Someone (I think the OP on this thread) asked the same question over at Stack Overflow and got an answer that looks right to me, so here's a link for anyone else looking for a solution
