+Examples
+--------
+- Create a new port mapping for a specific IP address
+
+     java -jar PortMapper.jar -add -externalPort <port> -internalPort <port> -ip <ip-addr> -protocol tcp
+
+- Create a new port mapping for the local machine (just omit the IP)
+
+     java -jar PortMapper.jar -add -externalPort <port> -internalPort <port> -protocol tcp
+
+- Delete a port forwarding
+
+     java -jar PortMapper.jar -delete -externalPort <port> -protocol tcp
+
+- List existing port forwardings
+
+     java -jar PortMapper.jar -list
+
+UPnP libraries
+--------------
+
+PortMapper includes three third party UPnP libraries. If the default does not work for your device, try using a different library.

+- [Cling](http://4thline.org/projects/cling/): `org.chris.portmapper.router.cling.ClingRouterFactory` (default)
+- [weupnp](https://github.com/bitletorg/weupnp): `org.chris.portmapper.router.weupnp.WeUPnPRouterFactory`
+- [SBBI UPnP lib](https://sourceforge.net/projects/upnplibmobile/): `org.chris.portmapper.router.sbbi.SBBIRouterFactory`
+- `org.chris.portmapper.router.dummy.DummyRouterFactory` (for testing)
