Comment 15 for bug 1271595

I've got a branch now which installs the file to /usr/share/appdata, but I'm struggling with verifying whether it works.

I'm testing on Ubuntu Yakkety with gnome-software (which I believe should use and display the information from appdata?). I don't see any effect when looking at the widelands package, nor for instance gnome-mines if I edit or replace the contents of the appdata file.

Is gnome-software actually using the appdata files, or is it just using regular package information? Is there any program on Ubuntu(/Debian) where I can easily test if this works?
