# Usage: makehdimage [-i includeFile] [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.
#
# If you don't specify the image, $sourceDir/haiku.image will be used. In
# the current default configuration, you have to start this script in the
# "current" directory of the Haiku tree. A 60 MB image will be created there.
#
# If you specify a target directory, no image is going to be created at
# all.
#
# If you pass `-i includeFile', the file is sourced before unmounting the
# image.
#
# The image is populated using the bfs_shell which is created from the sources.
# The bfs_shell emulates a mini-kernel evironment with a mounted BFS. The
# program fs_shell_command is used to deliver commands to it. Due to this
# setup a few things need to be kept in mind, if you intend to modify the
# script and want it to still work.
#
# All commands that modify the target (directory or image) are to be called
# through variables (defined after the jam invocation block). This ensures
# that both applications (creating and image and just installing the stuff in
# a target directory) do still work. Additionally there's a variable `sPrefix'
# defined, which has to be prepended to every source path, when passing the
# path to such a command.
#
# A further particularity to consider is changing the current working
# directory. When the shell command `cd' is invoked here, it affects only
# the shell which executes this script; the bfs_shell will know nothing of
# it. Hence, if you want the bfs_shell to know of a changed directory, you
# must tell it. There are two commands bound to variables: `$cd' should be
# used, when you want to change into a target directory, `$scd' when the
# source directory shall be changed. In the latter case you usually invoke
# first a normal shell `cd' and then the `$scd', so that both, the shell and
# the bfs_shell know about the new dir (depending on what you intend to do
# one may be enough, though).
