mkcdimage

#!/usr/bin/env bash
#
# Script to create a bootable CD image file containing rEFInd.
# Usage:
#
#   ./mkcdimage {version}
#
# where {version} is the rEFInd version number.
#
# This script relies on the mcopy utility.
#
# The script creates an image file from the binary package
# stored in ../snapshots/{version}/refind-bin-{version}.zip
# The resulting CD image file is stored in
# ../snapshots/{version}/refind-cd-{version}.iso

StartDir=$(pwd)
Version=$1

# Unzip the binary archive file....
