Knoppix-installer only copy Knoppix from CD (DVD) to a hard disk and add some scripts? That is all?

(1) How can I localize (translate for my language) knoppix-installer in text mode and KDE graphical mode. Which files should I edit and what is the name of tool (program, software) I can do it?

(2) I would like to have knoppix-installer in two languages: english and polish. How can I do it?

Any ideas?

Please help.
