There is a manual, faq and wiki here: http://live.debian.net/manual/html/ http://wiki.debian.org/DebianLive/FAQ http://wiki.debian.org/DebianLive/ The actual application is lh_config so type: lh_config --help for a list of options, then run lh_config to create the build directory, then lh_build to create the iso. You can edit the config files to modify the build and reuse the .deb files etc. drbongo
