# JoeyLib top-level Makefile.
#
# Usage:
#   source toolchains/env.sh    (first, every shell session)
#   make                        builds every target whose toolchain is present
#   make iigs                   builds Apple IIgs only
#   make amiga                  builds Commodore Amiga only
#   make atarist                builds Atari ST only
#   make dos                    builds MS-DOS only
#   make clean                  removes all build outputs
#
# The build references cross tools exclusively from toolchains/, set up
# by sourcing toolchains/env.sh. Do not invoke make without sourcing
# env.sh first or builds will fail with missing tool errors.
