In 2002, Sam Williams wrote Free as in Freedom, a biography of Richard M. Stallman. In its epilogue, Williams expressed hope that choosing to distribute his book under the GNU Free Documentation License would enable and encourage others to share corrections and their own perspectives through modifications to his work. Free as in Freedom (2.0) is Stallman's revision of the original biography. While preserving Williams's viewpoint, it includes factual corrections and extensive new commentary by Stallman, as well as new prefaces by both authors written for the occasion. It is a rare kind of biography, where the reader has the benefit of both the biographer's original words and the subject's response.

GRUB is a multiboot bootloader. It is used for initially loading the kernel of an operating system and then transferring control to it. The kernel then goes on to load the rest of the operating system. As a multiboot bootloader, GRUB handles the presence of multiple operating systems installed on the same computer; upon booting the computer, the user is presented with a menu to select one of the installed operating systems.
