All of the options can be loaded into the config file, of which the template is provided in `config_template.ini`, and utilized with `python3 fanficdownload.py -c path_to_config.ini`.
For basic cron usage, this is not needed, `fanficfare -dowload-imap -u` should work if you're not integrating into calibre. This script is best used if you want to update the calibre library, for the usage of calibre-server for instance.
