'''
ENLIVEN subgame builder - creates ENLIVEN based on minetest_game
Merges mods & settings from old bash installer script

mt_conf_by_mod settings should be placed in minetest.conf
but go in f"{destination}/minetest.conf" by default. See also:
- patches/subgame/minetest.conf
  To define the game.
- patches/subgame/minetest.server-example.conf goes in the server only.
  - Place the result in the game directory such as will result in
    f"worlds/{world}/ENLIVEN/minetest.conf"
- patches/subgame/minetest.client-example.conf goes in clients only.
