So I released 0.1 and 0.2. Now Caboodle has a menu bar (whee), an icon and a .desktop file.

To clarify something: you do not need OCaml or the Gtk+ and Cairo OCaml bindings to run Caboodle, just to compile it. I do not provide binaries at the moment, but if there's demand I can put up a pre-compiled Linux/x86 version.
