--- Comment #32 from Jeff Peeler jpeeler@redhat.com --- This is what I had in mind for the github handling:
http://people.redhat.com/jpeeler/gnome-shell-extension-system-monitor-applet...
Basically the source URL pointing to: https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet/tarball/%... where %{git} is a sha from master.
