CONFIG_DEFAULT_RESOURCES
  If defined, read resource configuration from the specified file if
  it cannot find the configuration file in the home directory.

CONFIG_EXTRA_SCREEN_INIT
  Can be a C code to be executed after the video mode is set, but before
  any other screen initialization is done.

CONFIG_GLOBAL_HASH_SIZE
  Size of global hash table when reading class definition file. This must
  be less than 65535.

CONFIG_LOCAL_HASH_SIZE
  Size of local hash table when reading class definition file. This must
  be less than 65535.

CONFIG_ERROR_CHECKING
  Define error checking level, where 9 is maximum. Lower numbers might
  improve speed but may make the program crash in some cases and may also
  cause security vulnerabilities.

CONFIG_EXTRA_SCREEN_INIT
  Can be a C code to be executed after the video mode is set, but before
  any other screen initialization is done.

CONFIG_LAUNCHER_PATH
  If defined, then it is the full path to a file to execute if Free Hero
  Mesh has been invoked with no command-line arguments, or if it is given
  the flag to run the launcher program instead.
  the flag to run the launcher program instead. (Maybe this should not be

  (Meant for storing scores on a multiuser system, somehow)

CONFIG_OMIT_EDITOR
  If defined, omit the level editor and picture editor, as well as the
  ability to import and export levels and pictures.
