2 # TazLito - SliTaz Live Tool.
3 #
4 # Tazlito is a tool to help generating and configuring SliTaz LiveCD
5 # ISO images. You can creat a custom distro in one command from a list of
6 # packages, extract a existing ISO image to hack it, creat new initramfs
7 # and/or new ISO. Most commands must be run by root, expect the stats
8 # and the configuration file manipulation.
