# mkcd.sh  -- Build DVX and create a CD-ROM ISO image for the target emulator
#
# Usage: ./mkcd.sh
#
# Builds the full DVX stack (dvx, tasks, shell, apps), then creates
# an ISO 9660 image from the bin/ directory.  The ISO uses short
# 8.3 filenames (-iso-level 1) for DOS compatibility.
#
# The ISO is placed in the emulator's data directory so it can be
# mounted as a CD-ROM drive.
