# @file Privoxy Configuration
# @brief This script applies the Privoxy configuration stored at `${XDG_CONFIG_HOME:-HOME/.config}/privoxy/config` to the system and then restarts Privoxy
# @description
#     Privoxy is a web proxy that can be combined with Tor to provide an HTTPS / HTTP proxy that can funnel all traffic
#     through Tor. This script:
#
#     1. Determines the system configuration file location
#     2. Applies the configuration stored at `${XDG_CONFIG_HOME:-HOME/.config}/privoxy/config`
#     3. Enables and restarts the Privoxy service with the new configuration
