      Supplies the main userspace tooling for using and configuring WireGuard tunnels, including the wg(8) and wg-quick(8) utilities.
      - wg : the configuration utility for getting and setting the configuration of WireGuard tunnel interfaces. The interfaces
        themselves can be added and removed using ip-link(8) and their IP addresses and routing tables can be set using ip-address(8)
        and ip-route(8). The wg utility provides a series of sub-commands for changing WireGuard-specific aspects of WireGuard interfaces.
      - wg-quick : an extremely simple script for easily bringing up a WireGuard interface, suitable for a few common use cases.
