 bzgas-recipe-bypass=Skip modifying these recipes (comma-separated list).
 bzgas-list=If enabled, the text command [color=orange]BZList[/color] will dump a file to the script-output directory with a full list of recipes modified.\nRecommended to turn this off after you are done configuring your other settings.
 bzgas-boiler=Natural gas mod currnelty can incorporate ElAdamo's public domain fluid boiler. If that mod is updated to 1.1, this may be removed.
 bzgas-handcraft=This enables an alternative wood-based handcrafting-only recipe for electronic circuits. Defaults to off, as bakelite only takes a few steps to make, but provided to enable varying playstyles.
+bzgas-force-spawn=Force a spawn of natural gas in the starting area, if the game does not spawn one.
