# eliminated, though. Only usage should be for selecting the default config
# file (and for that we should really rather allow overriding the value of
# DEFAULT_CONFIG_FILE).
# There are a few game specific hacks which are currently controlled by this,
# too; we need to investigate those.
# * It does not currently adjust the logo. Ideally, if we ever get real plugin
# support, that should be necessary anymore anyway.
