NetHack checks the following environment variables:
- NETHACKOPTIONS - You can define configuration options here.
- HACKOPTIONS - The same as NETHACKOPTIONS, but used only if NETHACKOPTIONS was not defined.
- WIZKIT - Allow wizard mode games to start with extra items.
- ROGUEOPTS - Set the ghost name in the Rogue level. For example, setting ROGUEOPTS's value to name=Foo would name the ghost to 'Foo'
- SHOPTYPE - For wizard mode debugging, forces a creation of a special room. For example, setting this to z will make a Treasure zoo on every level.
