What you mean and where can i get that?
Please read the documentation of the tools you want to use instead of
pestering the mailing list with stupid questions.
Or try using Revisor instead of using livecd-creator directly. What you're
trying to use is not Revisor, it's the command-line livecd-creator tool
(which definitely expects you to know what you're doing). Revisor can be
found in your menu, it's a graphical application. But even when using
Revisor, reading the documentation is definitely a good idea!
