+/**
+ * An implementation of the SelectChannelConnector which first tries to  
+ * inherit from a channel provided by the system. If there is no inherited
+ * channel available, or if the inherited channel provided not usable, then 
+ * it will fall back upon normal ServerSocketChannel creation.
+ * <p> 
+ * Note that System.inheritedChannel() is only available from Java 1.5 onwards.
+ * Trying to use this class under Java 1.4 will be the same as using a normal
+ * SelectChannelConnector. 
+ * <p> 
+ * Use it with xinetd/inetd, to launch an instance of Jetty on demand. The port
+ * used to access pages on the Jetty instance is the same as the port used to
+ * launch Jetty.
