From 296dc5bb53c430c8842ab7327d8a76b5750c64b4 Mon Sep 17 00:00:00 2001
From: Martin Whitaker <mageia@martin-whitaker.me.uk>
Date: Mon, 18 Dec 2017 10:54:01 +0000
Subject: Start creating a new set of tools for generating Mageia ISO images.

The aim is to share as much code as possible between the tool used
to generate the Live ISOs and the tool used to generate the classic
installer ISOs.

This is derived from the user/martinw/use-grub2 branch of draklive.
