# Transform a qemu-cmd file to allow reuse.
#
# Usage: kvm-transform.sh bzImage console.log jitter_dir [ seconds ] < qemu-cmd-in > qemu-cmd-out
#
# bzImage: Kernel and initrd from the same prior kvm.sh run.
# console.log: File into which to place console output.
#
# The original qemu-cmd file is provided on standard input.
# The transformed qemu-cmd file is on standard output.
# The transformation assumes that the qemu command is confined to a
# single line. It also assumes no whitespace in filenames.
