+	  strongSwan is an OpenSource IPsec implementation for the
+	  Linux operating system. It is based on the discontinued
+	  FreeS/WAN project and the X.509 patch.
+
+	  The focus is on:
+	     - simplicity of configuration
+	     - strong encryption and authentication methods
+	     - powerful IPsec policies supporting large and complex VPN networks
+
+	  strongSwan provide many plugins. Only a few are presented here.
