GRand Unified Bootloader (common files)
This package contains common files shared by the distinct flavours of GRUB.
It is shared between GRUB Legacy and GRUB 2, although a number of files
specific to GRUB 2 are here as long as they do not break GRUB Legacy.

grub-mkrescue needs the suggested packages mtools (for UEFI targets) and
xorriso.
