+Description: GRand Unified Bootloader, version 2 (MIPS Loongson LEFI modules)
+ GRUB is a portable, powerful bootloader.  This version of GRUB is based on a

+  - Scripting in grub.cfg using BASH-like syntax.
+  - Support for modern partition maps such as GPT.
+  - Modular generation of grub.cfg via update-grub.  Packages providing GRUB

+ This package contains GRUB modules that have been built for use on MIPS
