# @brief This script applies the Tor configuration stored at `${XDG_CONFIG_HOME:-HOME/.config}/tor/torrc` to the system and then restarts Tor
# @description
#     Tor is a network that uses onion routing, originally published by the US Navy. It is leveraged by privacy enthusiasts
#     and other characters that deal with sensitive material, like journalists and people buying drugs on the internet.
#     This script:
#
#     1. Determines the system configuration file location
#     2. Applies the configuration stored at `${XDG_CONFIG_HOME:-HOME/.config}/tor/torrc`
#     3. Enables and restarts the Tor service with the new configuration
