[opensuse-buildservice] ymp for upgrade?

Hello, We want to create a ymp (1-Click) which will cause the user to upgrade all packages provided by our repository which are installed, but not ask the user to install anything which is not installed. Is such a thing possible? -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org
