# \brief Turn a Genode setup(run script) into a VM to be bootable in Seoul
# \author Alexander Boettcher
# \date 2014-09-21
#
# This run script starts the Seoul VMM booting from a multiboot Genode setup
# created by another Genode run script. The referenced run script can be
# adapted by tuning the variables run_script and build_dir below accordingly.
