Universal Binary?

Hi all!
The "Universal Binary Programming Guidelines, Second Edition" is mainly about how to write universal binary.But there is no information about the principle of universal binary,such as how the universal binary works,how to generate them.Is there any document about these?

There must't be two "-arch" parameters,such as "-arch ppc -arch i386"(generating universal binary),with gcc command "gcc -E".So I also want to know how and when the gcc generates the universal binary ?
thks!
