#!/bin/sh

# Usage: makehdimage [image path/target dir]
#
# This script will compile all files needed to create a bootable Haiku image,
# create such an image, and copy the files to the correct location.
#
# You need the Userland FS Server package from Ingo Weinhold to successfully
# create the image, and you also need to have the UserlandFSServer running
# in the background when you start the script (as long as you don't use
# the target directory mode).
#
# If you don't specify the image, $sourceDir/haiku.image will be used. In
# the current default configuration, you have to start this script in the
# "current" directory of the Haiku tree. A 40 MB image will be created there.
#
# If you specify a target directory, no image is going to be created at
# all, and also the Userland FS Server is not needed.
#
# You may want to change it to suit your needs. Have fun!
