+ help
+ This User-Mode Linux network transport allows one or more running
+ UMLs on a single host to communicate with each other and also
+ with the rest of the world using Virtual Distributed Ethernet,
+ an improved fork of uml_switch.
+
+ You must have libvdeplug installed in order to build the vde
+ transport into UML.
+
+ To use this form of networking, you will need to run vde_switch
+ on the host.
+
+ For more information, see <http://wiki.virtualsquare.org/>
+ That site has a good overview of what VDE is and also examples
+ of the UML command line to use to enable VDE networking.
+
+ If you need UML networking with VDE,
+ say Y.
