Usage: $0 [OPTION...]

Application data can be found in ~/.var/app/com.bay12games.DwarfFortress/df_linux/

By default, this will launch plain Dwarf Fortress.
If a dfhack init file exists then it will launch DFHack by default.

If a file named .dfrc exists in df_linux, then it will be sourced before launching Dwarf Fortress.
If a file named .dfhackrc exists in df_linux, then it will be sourced before setting up dfhack.

Options:
 -d   Runs plain Dwarf Fortress
 -h   Runs dfhack, creating an init file if one doesn't already exist
 -t   Run dfhack with TWBT
