# Transmission does not allow multiple blocklist by default or is not simple.
# This script merges multiple blocklist into one file.
# Be sure to restart your bt client/daemon to use the new iplist.
# Make sure to enable the blocklist and keep the url empty in your config file.
# Example:
#     "blocklist-enabled": true,
#     "blocklist-url": "",
