# 
# note: when switching between different hardware targets, don`t forget
#       "make clean" in between
#
# tools required:
#  GNU Make, either VBCC or GCC for AmigaOS/68k, VASM
#  recent sana2.h , e.g. from RoadShow SDK
#
# porting:
#  you might need to adapt the paths (prefix for Compiler/Includes)
#  Some installations have ADE: instead of GG: on Amigaos
#  Recent work on AmigaOS cross toolchains suggest /opt/m68k-amigaos/sys-include
#  instead of the traditional os-include
