Makefile

# general
-include Makefile.config
# tools, sprites, lang, code entries need to be specified in Makefile.config
# though the Makefile itself provides default values that can be used if
# following the build instructions in README.md (using scoop to install the tools)
#
# You can override the default values by specifying them in Makefile.config
# this would be useful if e.g. you manually compiled gorender and it's not in your PATH
