It generates console scripts and .exe wrappers.
I decided not to implement find_package_data(), because it turned out to be a lot more complex than I thought it would be. In fact, it was complex enough that I was wondering if I might need to rewrite the entire distutils in order to make it work well. :(
Anyway, 0.6a2 is out, so enjoy. I'd be interested in hearing feedback on how the GUI wrappers should be done. I've already figured out how to compile a launcher variant that doesn't create a console window on Windows, so that part's easy. I guess we can always add fancy features for Mac et al later.
One thing I'm not too sure about for GUIs on non-Windows platforms is the whole detach or not-to-detach thing. On Windows, I was planning to make GUIs run detached from the current console, but I'm not sure if that's the "normal" thing to do on other platforms.
