How to create the control file for AutoYast2

Hi all, I try to install SuSE 8.0 from NFS server by using AutoYast2. I've already create a boot floppy. According to the document on AutoYast2 http://www.suse.de/~nashif/autoinstall/ you have to create the control file and make sure that package yast2-config-autoinst install on the system. 1) could somebody show me where can I get the package yast2-config-autoinst ? 2) How to create control file using the system ? Thank you very much, Long,
