+define Package/libjuice/description
+  libjuice ("JUICE is a UDP Interactive Connectivity Establishment library")
+  is a lightweight implementation of ICE (RFC 8445) in C, allowing to open
+  a peer-to-peer UDP connection between two hosts behind NAT by hole
+  punching, using STUN (RFC 8489) to gather reflexive candidates and
+  optionally TURN (RFC 8656) to relay. It also provides a minimal
+  STUN/TURN server implementation.
