    longDescription =
      '' 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).
