Well, if it weren't a day late and a dollar short in my completion of such tutorials at GTK and Glade, I behold thee HavenCo quittage application for your favority Linux Desktop. In other words, this application is just as useful as GTKtrue.
Therapeutic though, how everybody is quitting and not quitting havenco. This appy compliments Neale Pickett's web application, and spawned from its earlier predocessor, written in Gtk.
I hope you like it. Pull my finger.
