%description
Yggdrasil is an early-stage implementation of a fully end-to-end encrypted IPv6 network. It is lightweight, self-arranging,
supported on multiple platforms and allows pretty much any IPv6-capable application to communicate securely with other Yggdrasil nodes.
Yggdrasil does not require you to have IPv6 Internet connectivity - it also works over IPv4.

Although Yggdrasil shares many similarities with cjdns, it employs a different routing algorithm based on a globally-agreed spanning
tree and greedy routing in a metric space, and aims to implement some novel local backpressure routing techniques. In theory,
Yggdrasil should scale well on networks with internet-like topologies.
