GRUB is a portable, powerful bootloader. This version of GRUB is based on a cleaner design than its predecessors, and provides the following new features:

- 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 add-ons can plug in their own script rules and trigger updates by invoking update-grub.

This is a dependency package for a version of GRUB that has been built for use with the Xen hypervisor (i.e. PV-GRUB). Installing this package indicates that this version of GRUB should be the active boot loader.
