+version: 2.1.0
+summary: Peer-to-peer VPN
+description: |
+  VpnCloud is a high performance peer-to-peer mesh VPN over UDP supporting strong encryption, 
+  NAT traversal and a simple configuration. It establishes a fully-meshed self-healing VPN
+  network in a peer-to-peer manner with strong end-to-end encryption based on elliptic curve
+  keys and AES-256. VpnCloud creates a virtual network interface on the host and forwards all
+  received data via UDP to the destination. It can work on TUN devices (IP based) and TAP 
+  devices (Ethernet based).
