This module defines the Bootloader class.
Bootloader: a program to boot Kernels on a Host.

class Bootloader(boottool.boottool):
This class gives access to a host's bootloader services.
It can be used to add a kernel to the list of kernels that can be
booted by a bootloader. It can also make sure that this kernel will
be the one chosen at next reboot.
