I'm working on adding apturl support to Linux App Finder so programs in a deb repository can be installed just by clicking a link. Since not every system will have apturl installed, I'd like to be able to detect whether or not the browser can handle an apt: link and use the information to display appropriate instructions. Does anyone know how to do that?

The Marillat repository has been updated to its new location at http://www.debian-multimedia.org/. Ubuntu Dapper backports and the new Edgy mirrors have been added.
