 define Package/babeld/description
- Babel is a loop-avoiding distance-vector routing protocol roughly based
- on DSDV and AODV, but with provisions for link cost estimation and
- redistribution of routes from other routing protocols.
- While it is optimised for wireless mesh networks, Babel will also work
- efficiently on wired networks. It will generate between 1.2 and 2.4 times
- the amount of routing traffic that RIPng would generate, while
- never counting to infinity.
+  Babel is a loop-avoiding distance-vector routing protocol for IPv6 and IPv4
+  with fast convergence properties. It is based on the ideas in DSDV, AODV and
+  Cisco's EIGRP, but is designed to work well not only in wired networks but
+  also in wireless mesh networks, and has been extended with support for
+  overlay networks. Babel is in the process of becoming an IETF Standard.
