It is written using the gtk toolkit. Max is also maintaining an rpm of the development version. You can download the latest source here . This release adds support for gShield 2.x and is current with gShield 2.0.3.
Source is available for download .
So I'm releasing it as source only for now. A note on the binaries. These are my first packages. They're currently not checking for dependencies automatically so beware, you might get errors loading shared libs. You will need to have gtk and gnome-xml installed in order to run.
