"""
ArchiveBox config definitons (including defaults and dynamic config options).

Config Usage Example:

    archivebox config --set MEDIA_TIMEOUT=600
    env MEDIA_TIMEOUT=600 USE_COLOR=False ... archivebox [subcommand] ...

Config Precedence Order:

  1. cli args                 (--update-all / --index-only / etc.)
  2. shell environment vars   (env USE_COLOR=False archivebox add '...')
  3. config file              (echo "SAVE_FAVICON=False" >> ArchiveBox.conf)
  4. defaults                 (defined below in Python)
