SUMMARY = "GRUB2 is the next-generation GRand Unified Bootloader" DESCRIPTION = "GRUB2 is the next generaion of a GPLed bootloader \ intended to unify bootloading across x86 operating systems. In \ addition to loading the Linux kernel, it implements the Multiboot \ standard, which allows for flexible loading of multiple boot images."
