I'm pleased to annouce that apturl support has been added to Linux App Finder. apturl is a program enabling single-click installs from within a browser. It is currently in the Ubuntu Gutsy repositories, but versions for Debian and Ubuntu Feisty are also available.
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?
