The app itself is certainly not 7MB Unpacked, its about 115kb including icons and stuff. All the bloat comes from libboost and libqt. The ugly libboost dependency will go away once the PySide people release "Shiboken". edit: Oh and yeah, it's optified and if I'm not mistaken it's dependencies are as well. Someone installed it a minute ago and told me he didn't lose a bit on /.
