Note: normally, you would use AddApp rather than Zero2Bundle. AddApp creates small launchers, which will download the application if required and store it in the cache. The launchers will automatically check for updates, run the correct binary for different platforms, and share libraries. Zero2Bundle, by contrast, copies the program and all required libraries into the created directory. This is useful if the target machine doesn't have a network connection, for example.
See also: 0export, which provides similar functionality for GNOME and KDE users.
