-      GNU GRUB is a Multiboot boot loader. It was derived from GRUB, GRand
-      Unified Bootloader, which was originally designed and implemented by
-      Erich Stefan Boleyn.
-
-      Briefly, the boot loader is the first software program that runs when a
-      computer starts.  It is responsible for loading and transferring
-      control to the operating system kernel software (such as the Hurd or
-      the Linux).  The kernel, in turn, initializes the rest of the
-      operating system (e.g., GNU).
