# Maintainer: Jesus Alonso <doragasu at hotmail dot com>
# NOTE: As I want these packages for Genesis/Megadrive development, they do
# only support the m68000 CPU. If you want to support other m68k variants,
# either modify _target_cpu to suit your needs, or go wild, remove the
# --with-cpu switches and change --disable-multilib with --enable-multilib.
# Be warned that multilib packages will take a lot more time to build, and
# will also require more disk space.
