define Package/yggdrasil/description
 Yggdrasil builds end-to-end encrypted networks with IPv6.
 Beyond the similarities with cjdns is a different routing
 algorithm. This globally-agreed spanning tree uses greedy
 routing in a metric space. Back-pressure routing techniques
 allow advanced link aggregation bonding on per-stream basis.
 In turn, a single stream will span across multiple network
 interfaces simultaneously with much greater throughput.
