CrossOver Support - Community Forums

Hey! This is not about using CrossOver itself but its inner workings, still I think this is the best place to ask.
I just discovered that, like with the Linux version, the CrossOver Mac UI is Python-based, too. But the executable is a binary and not the general purpose interpreter with arguments. Being a Python developer myself, I would like to know if this was customly built by CodeWeavers or maybe created by some App packaging toolkit that I could use for my own projects, since it seems perfectly integrated.
Thanks.

I don't know exactly how CrossOver builds/packages their app, but it's built with Python GTK. A common (and possibly the only) way to build Python GTK apps is to use gtk-osx, gtk-mac-bundler, and gtk-mac-integration. I tried including links to the projects but my comment keeps getting denied when I include them.

Edit: Got the links in by editing the message after posting.

Thanks, I already work with GTK+ & PyGObject. What I'm interested in is the packaging, e.g. how to make it an .app without using a launcher script to run the interpreter. That works, but is not as clean as the CrossOver way. "gtk-mac-bundler" might solve the problem of bundling the GTK libraries, but I would still need a binary first.
