# 86Box     A hypervisor and IBM PC system emulator that specializes in
#           running old operating systems and software designed for IBM
#           PC systems and compatibles from 1981 through fairly recent
#           system designs based on the PCI bus.
#
#           This file is part of the 86Box distribution.
