# To whomever it may concern:
#
# This directory menaces with spikes of Nix code. It is terrifying.
#
# If this is your first time here, you should probably install the dwarf-fortress-full package,
# for instance with:
#
# environment.systemPackages = [ pkgs.dwarf-fortress-packages.dwarf-fortress-full ];
#
# You can adjust its settings by using override, or compile your own package by
# using the other packages here.
#
# For example, you can enable the FPS indicator, disable the intro, pick a
# theme other than phoebus (the default for dwarf-fortress-full), _and_ use
# an older version with something like:
#
# environment.systemPackages = [
#   (pkgs.dwarf-fortress-packages.dwarf-fortress-full.override {
#      dfVersion = "0.44.11";
#      theme = "cla";
#      enableIntro = false;
#      enableFPS = true;
#   })
# ]
#
# Take a look at lazy-pack.nix to see all the other options.
#
# You will find the configuration files in ~/.local/share/df_linux/data/init. If
# you un-symlink them and edit, then the scripts will avoid overwriting your
# changes on later launches, but consider extending the wrapper with your
# desired options instead.
