+Description: fast, modern, secure kernel VPN tunnel (metapackage)
+ WireGuard is a novel VPN that runs inside the Linux Kernel and uses
+ state-of-the-art cryptography (the "Noise" protocol). It aims to be
+ faster, simpler, leaner, and more useful than IPSec, while avoiding
+ the massive headache. It intends to be considerably more performant
+ than OpenVPN. WireGuard is designed as a general purpose VPN for
+ running on embedded interfaces and super computers alike, fit for
+ many different circumstances. It runs over UDP.
+ .
+ This metapackage explicitly depends on both the kernel module and the
+ userspace tooling.
