mklivecd is a script for Linux distributions that allows for one to compile a "snapshot" of the current hard drive partition and all data which resides in it (all settings, applications, documents, bookmarks, etc.) and compress it into an ISO 9660 CD-image. This allows easy backup of a user's data and also makes it easy to create customized Linux-distribution. Some Linux-distributions like PCLinuxOS include a graphical frontend for easier script usage.
