You are not installing a .desktop file for your application to tell
Nautilus /how/ to run your application, or when to show your
application in menus, etc. Nautilus (actually, GIO's AppLaunch code)
could probably guess and just do "app-name filename", but it's often
not going to work, e.g. if your app needs flags to tell it that you're
opening a file ("app-name -f filename"). That's why we have the
Desktop Entry Spec, and that's why applications install
app-name.desktop files in $(datadir)/applications.
