 Other configuration available:
 - `CF_PARALLEL_DOWNLOADS` (default is 4): specify how many parallel mod downloads to perform
 - `CF_OVERRIDES_SKIP_EXISTING` (default is false): if set, files in the overrides that already exist in the data directory are skipped. **NOTE** world data is always skipped, if present.
